A Fragment is a piece of an application's user interface or behavior that can be placed in an[Activity](https://developer.android.com/reference/kotlin/android/app/Activity). Interaction with fragments is done through[FragmentManager](https://developer.android.com/reference/kotlin/android/app/FragmentManager), which can be obtained via[Activity.getFragmentManager()](https://developer.android.com/reference/kotlin/android/app/Activity#getFragmentManager())and[Fragment.getFragmentManager()](https://developer.android.com/reference/kotlin/android/app/Fragment#getFragmentManager()). The Fragment class can be used many ways to achieve a wide variety of results. In its core, it represents a particular operation or interface that is running within a larger[Activity](https://developer.android.com/reference/kotlin/android/app/Activity). A Fragment is closely tied to the Activity it is in, and can not be used apart from one. Though Fragment defines its own lifecycle, that lifecycle is dependent on its activity: if the activity is stopped, no fragments inside of it can be started; when the activity is destroyed, all fragments will be destroyed. All subclasses of Fragment must include a public no-argument constructor. The framework will often re-instantiate a fragment class when needed, in particular during state restore, and needs to be able to find this constructor to instantiate it. If the no-argument constructor is not available, a runtime exception will occur in some cases during state restore. Topics covered here: 1. [Older Platforms](https://developer.android.com/reference/kotlin/android/app/Fragment#OlderPlatforms) 2. [Lifecycle](https://developer.android.com/reference/kotlin/android/app/Fragment#Lifecycle) 3. [Layout](https://developer.android.com/reference/kotlin/android/app/Fragment#Layout) 4. [Back Stack](https://developer.android.com/reference/kotlin/android/app/Fragment#BackStack) | ### Developer Guides | | For more information about using fragments, read the[Fragments](https://developer.android.com/guide/components/fragments.html)developer guide. ### Older Platforms While the Fragment API was introduced in[android.os.Build.VERSION_CODES#HONEYCOMB](https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#HONEYCOMB:kotlin.Int), a version of the API at is also available for use on older platforms through androidx.fragment.app.FragmentActivity. See the blog post[Fragments For All](http://android-developers.blogspot.com/2011/03/fragments-for-all.html)for more details. ### Lifecycle Though a Fragment's lifecycle is tied to its owning activity, it has its own wrinkle on the standard activity lifecycle. It includes basic activity lifecycle methods such as[onResume](https://developer.android.com/reference/kotlin/android/app/Fragment#onResume()), but also important are methods related to interactions with the activity and UI generation. The core series of lifecycle methods that are called to bring a fragment up to resumed state (interacting with the user) are: 1. #onAttach called once the fragment is associated with its activity. 2. [onCreate](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreate(android.os.Bundle))called to do initial creation of the fragment. 3. [onCreateView](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateView(android.view.LayoutInflater,%20android.view.ViewGroup,%20android.os.Bundle))creates and returns the view hierarchy associated with the fragment. 4. [onActivityCreated](https://developer.android.com/reference/kotlin/android/app/Fragment#onActivityCreated(android.os.Bundle))tells the fragment that its activity has completed its own android.app.Activity#onCreate. 5. [onViewStateRestored](https://developer.android.com/reference/kotlin/android/app/Fragment#onViewStateRestored(android.os.Bundle))tells the fragment that all of the saved state of its view hierarchy has been restored. 6. [onStart](https://developer.android.com/reference/kotlin/android/app/Fragment#onStart())makes the fragment visible to the user (based on its containing activity being started). 7. [onResume](https://developer.android.com/reference/kotlin/android/app/Fragment#onResume())makes the fragment begin interacting with the user (based on its containing activity being resumed). As a fragment is no longer being used, it goes through a reverse series of callbacks: 1. [onPause](https://developer.android.com/reference/kotlin/android/app/Fragment#onPause())fragment is no longer interacting with the user either because its activity is being paused or a fragment operation is modifying it in the activity. 2. [onStop](https://developer.android.com/reference/kotlin/android/app/Fragment#onStop())fragment is no longer visible to the user either because its activity is being stopped or a fragment operation is modifying it in the activity. 3. [onDestroyView](https://developer.android.com/reference/kotlin/android/app/Fragment#onDestroyView())allows the fragment to clean up resources associated with its View. 4. [onDestroy](https://developer.android.com/reference/kotlin/android/app/Fragment#onDestroy())called to do final cleanup of the fragment's state. 5. [onDetach](https://developer.android.com/reference/kotlin/android/app/Fragment#onDetach())called immediately prior to the fragment no longer being associated with its activity. ### Layout Fragments can be used as part of your application's layout, allowing you to better modularize your code and more easily adjust your user interface to the screen it is running on. As an example, we can look at a simple program consisting of a list of items, and display of the details of each item. An activity's layout XML can include``tags to embed fragment instances inside of the layout. For example, here is a simple layout that embeds one fragment: The layout is installed in the activity in the normal way: The titles fragment, showing a list of titles, is fairly simple, relying on[ListFragment](https://developer.android.com/reference/kotlin/android/app/ListFragment)for most of its work. Note the implementation of clicking an item: depending on the current activity's layout, it can either create and display a new fragment to show the details in-place (more about this later), or start a new activity to show the details. The details fragment showing the contents of a selected item just displays a string of text based on an index of a string array built in to the app: In this case when the user clicks on a title, there is no details container in the current activity, so the titles fragment's click code will launch a new activity to display the details fragment: However the screen may be large enough to show both the list of titles and details about the currently selected title. To use such a layout on a landscape screen, this alternative layout can be placed under layout-land: Note how the prior code will adjust to this alternative UI flow: the titles fragment will now embed the details fragment inside of this activity, and the details activity will finish itself if it is running in a configuration where the details can be shown in-place. When a configuration change causes the activity hosting these fragments to restart, its new instance may use a different layout that doesn't include the same fragments as the previous layout. In this case all of the previous fragments will still be instantiated and running in the new instance. However, any that are no longer associated with a \ tag in the view hierarchy will not have their content view created and will return false from[isInLayout](https://developer.android.com/reference/kotlin/android/app/Fragment#isInLayout()). (The code here also shows how you can determine if a fragment placed in a container is no longer running in a layout with that container and avoid creating its view hierarchy in that case.) The attributes of the \ tag are used to control the LayoutParams provided when attaching the fragment's view to the parent container. They can also be parsed by the fragment in #onInflate as parameters. The fragment being instantiated must have some kind of unique identifier so that it can be re-associated with a previous instance if the parent activity needs to be destroyed and recreated. This can be provided these ways: - If nothing is explicitly supplied, the view ID of the container will be used. - `android:tag`can be used in \ to provide a specific tag name for the fragment. - `android:id`can be used in \ to provide a specific identifier for the fragment. ### Back Stack The transaction in which fragments are modified can be placed on an internal back-stack of the owning activity. When the user presses back in the activity, any transactions on the back stack are popped off before the activity itself is finished. For example, consider this simple fragment that is instantiated with an integer argument and displays that in a TextView in its UI: A function that creates a new instance of the fragment, replacing whatever current fragment instance is being shown and pushing that change on to the back stack could be written as: After each call to this function, a new entry is on the stack, and pressing back will pop it to return the user to whatever previous state the activity UI was in. Fragments appearing or disappearing do not generate system events for accessibility, so set a title on your fragments with[View.setAccessibilityPaneTitle(CharSequence)](https://developer.android.com/reference/kotlin/android/view/View.html#setAccessibilityPaneTitle(kotlin.CharSequence))to notify accessibility users of these UI transitions. ## Summary | Nested classes || |------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | open | [InstantiationException](https://developer.android.com/reference/kotlin/android/app/Fragment.InstantiationException) Thrown by[Fragment.instantiate(Context, String, Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#instantiate(android.content.Context,%20kotlin.String,%20android.os.Bundle))when there is an instantiation failure. | | open | [SavedState](https://developer.android.com/reference/kotlin/android/app/Fragment.SavedState) State information that has been retrieved from a fragment instance through[FragmentManager.saveFragmentInstanceState](https://developer.android.com/reference/kotlin/android/app/FragmentManager#saveFragmentInstanceState(android.app.Fragment)). | | Inherited constants || |---|---| | From class[ComponentCallbacks2](https://developer.android.com/reference/kotlin/android/content/ComponentCallbacks2.html#) |----------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html) | [TRIM_MEMORY_BACKGROUND](https://developer.android.com/reference/kotlin/android/content/ComponentCallbacks2.html#TRIM_MEMORY_BACKGROUND:kotlin.Int)

Called by the system when the device configuration changes while your component is running. Note that, unlike activities, other components are never restarted when a configuration changes: they must always deal with the results of the change, such as by re-retrieving resources. At the time that this function has been called, your Resources object will have been updated to return resource values matching the new configuration.

This is called when the overall system is running low on memory, and actively running processes should trim their memory usage. While the exact point at which this will be called is not defined, generally it will happen when all background process have been killed. That is, before reaching the point of killing processes hosting service and foreground UI that we would like to avoid killing.
| || ## Public constructors ### Fragment Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` Fragment() ``` Default constructor.**Every** fragment must have an empty constructor, so it can be instantiated when restoring its activity's state. It is strongly recommended that subclasses do not have other constructors with parameters, since these constructors will not be called when the fragment is re-instantiated; instead, arguments can be supplied by the caller with[setArguments](https://developer.android.com/reference/kotlin/android/app/Fragment#setArguments(android.os.Bundle))and later retrieved by the Fragment with[getArguments](https://developer.android.com/reference/kotlin/android/app/Fragment#getArguments()). Applications should generally not implement a constructor. Prefer[onAttach(android.content.Context)](https://developer.android.com/reference/kotlin/android/app/Fragment#onAttach(android.content.Context))instead. It is the first place application code can run where the fragment is ready to be used - the point where the fragment is actually associated with its context. Some applications may also want to implement #onInflate to retrieve attributes from a layout resource, although note this happens when the fragment is attached. ## Public methods ### dump Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun dump(     prefix: String!,     fd: FileDescriptor!,     writer: PrintWriter!,     args: Array! ): Unit ``` **Deprecated:** *Deprecated in Java.* Print the Fragments's state into the given stream. | Parameters || |----------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `prefix` | [String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!:Text to print at the front of each line. | | `fd` | [FileDescriptor](https://developer.android.com/reference/kotlin/java/io/FileDescriptor.html#)!:The raw file descriptor that the dump is being sent to. | | `writer` | [PrintWriter](https://developer.android.com/reference/kotlin/java/io/PrintWriter.html#)!:The PrintWriter to which you should dump your state.

By default fragments are shown. You can find out about changes to this state with[onHiddenChanged](https://developer.android.com/reference/kotlin/android/app/Fragment#onHiddenChanged(kotlin.Boolean)). Note that the hidden state is orthogonal to other states -- that is, to be visible to the user, a fragment must be both started and not hidden. ### isInLayout Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun isInLayout(): Boolean ``` **Deprecated:** *Deprecated in Java.* Return true if the layout is included as part of an activity view hierarchy via the \ tag. This will always be true when fragments are created through the \ tag,*except*in the case where an old fragment is restored from a previous state and it does not appear in the layout of the current state. ### isRemoving Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun isRemoving(): Boolean ``` **Deprecated:** *Deprecated in Java.* Return true if this fragment is currently being removed from its activity. This is*not*whether its activity is finishing, but rather whether it is in the process of being removed from its activity. ### isResumed Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun isResumed(): Boolean ``` **Deprecated:** *Deprecated in Java.* Return true if the fragment is in the resumed state. This is true for the duration of[onResume()](https://developer.android.com/reference/kotlin/android/app/Fragment#onResume())and[onPause()](https://developer.android.com/reference/kotlin/android/app/Fragment#onPause())as well. ### isStateSaved Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun isStateSaved(): Boolean ``` **Deprecated:** *Deprecated in Java.* Returns true if this fragment is added and its state has already been saved by its host. Any operations that would change saved state should not be performed if this method returns true, and some operations such as[setArguments(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#setArguments(android.os.Bundle))will fail. | Return || |------------------------------------------------------------------------------------|------------------------------------------------------------------| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | true if this fragment's state has already been saved by its host | ### isVisible Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun isVisible(): Boolean ``` **Deprecated:** *Deprecated in Java.* Return true if the fragment is currently visible to the user.

It can be used to do final initialization once these pieces are in place, such as retrieving views or restoring state. It is also useful for fragments that use[setRetainInstance(boolean)](https://developer.android.com/reference/kotlin/android/app/Fragment#setRetainInstance(kotlin.Boolean))to retain their instance, as this callback tells the fragment when it is fully associated with the new activity instance. This is called after[onCreateView](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateView(android.view.LayoutInflater,%20android.view.ViewGroup,%20android.os.Bundle))and before[onViewStateRestored(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onViewStateRestored(android.os.Bundle)). If you override this method you*must*call through to the superclass implementation. | Parameters || |----------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `savedInstanceState` | [Bundle](https://developer.android.com/reference/kotlin/android/os/Bundle.html#)?:If the fragment is being re-created from a previous saved state, this is the state.

This follows the related Activity API as described there in[Activity.onActivityResult(int, int, Intent)](https://developer.android.com/reference/kotlin/android/app/Activity#onActivityResult(kotlin.Int,%20kotlin.Int,%20android.content.Intent)). | Parameters || |---------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `requestCode` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):The integer request code originally supplied to startActivityForResult(), allowing you to identify who this result came from. | | `resultCode` | [Int](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-int/index.html):The integer result code returned by the child activity through its setResult(). | | `data` | [Intent](https://developer.android.com/reference/kotlin/android/content/Intent.html#)!:An Intent, which can return result data to the caller (various data can be attached to Intent "extras"). | ### onAttach Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 23](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onAttach(activity: Activity!): Unit ``` **Deprecated:** *Use[onAttach(android.content.Context)](https://developer.android.com/reference/kotlin/android/app/Fragment#onAttach(android.content.Context))instead.*
If you override this method you*must*call through to the superclass implementation. ### onAttach Added in[API level 23](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onAttach(context: Context!): Unit ``` **Deprecated:** *Deprecated in Java.* Called when a fragment is first attached to its context.[onCreate(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreate(android.os.Bundle))will be called after this. If you override this method you*must*call through to the superclass implementation. ### onAttachFragment Added in[API level 24](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onAttachFragment(childFragment: Fragment!): Unit ``` **Deprecated:** *Deprecated in Java.* Called when a fragment is attached as a child of this fragment. This is called after the attached fragment's`onAttach`and before the attached fragment's`onCreate`if the fragment has not yet had a previous call to`onCreate`. | Parameters || |-----------------|-----------------------------------------------------------------------------------------------------------------| | `childFragment` | [Fragment](https://developer.android.com/reference/kotlin/android/app/Fragment#)!:child fragment being attached | ### onConfigurationChanged Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onConfigurationChanged(newConfig: Configuration): Unit ``` **Deprecated:** *Deprecated in Java.* Called by the system when the device configuration changes while your component is running. Note that, unlike activities, other components are never restarted when a configuration changes: they must always deal with the results of the change, such as by re-retrieving resources. At the time that this function has been called, your Resources object will have been updated to return resource values matching the new configuration. For more information, read[Handling Runtime Changes](https://developer.android.com/guide/topics/resources/runtime-changes.html). If you override this method you*must*call through to the superclass implementation. | Parameters || |-------------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `newConfig` | [Configuration](https://developer.android.com/reference/kotlin/android/content/res/Configuration.html#):The new device configuration. This value cannot be`null`. | ### onContextItemSelected Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onContextItemSelected(item: MenuItem!): Boolean ``` **Deprecated:** *Deprecated in Java.* This hook is called whenever an item in a context menu is selected. The default implementation simply returns false to have the normal processing happen (calling the item's Runnable or sending a message to its Handler as appropriate). You can use this method for any items for which you would like to do processing without those other facilities. Use[MenuItem.getMenuInfo()](https://developer.android.com/reference/kotlin/android/view/MenuItem.html#getMenuInfo())to get extra information set by the View that added this menu item. Derived classes should call through to the base class for it to perform the default menu handling. | Parameters || |--------|----------------------------------------------------------------------------------------------------------------------------------| | `item` | [MenuItem](https://developer.android.com/reference/kotlin/android/view/MenuItem.html#)!:The context menu item that was selected. | | Return || |------------------------------------------------------------------------------------|---------------------------------------------------------------------------------------------------| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | boolean Return false to allow normal context menu processing to proceed, true to consume it here. | ### onCreate Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onCreate(savedInstanceState: Bundle?): Unit ``` **Deprecated:** *Deprecated in Java.* Called to do initial creation of a fragment. This is called after[onAttach(android.app.Activity)](https://developer.android.com/reference/kotlin/android/app/Fragment#onAttach(android.app.Activity))and before[onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateView(android.view.LayoutInflater,%20android.view.ViewGroup,%20android.os.Bundle)), but is not called if the fragment instance is retained across Activity re-creation (see[setRetainInstance(boolean)](https://developer.android.com/reference/kotlin/android/app/Fragment#setRetainInstance(kotlin.Boolean))). Note that this can be called while the fragment's activity is still in the process of being created. As such, you can not rely on things like the activity's content view hierarchy being initialized at this point. If you want to do work once the activity itself is created, see[onActivityCreated(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onActivityCreated(android.os.Bundle)). If your app's`targetSdkVersion`is[android.os.Build.VERSION_CODES#M](https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#M:kotlin.Int)or lower, child fragments being restored from the savedInstanceState are restored after`onCreate`returns. When targeting[android.os.Build.VERSION_CODES#N](https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#N:kotlin.Int)or above and running on an N or newer platform version they are restored by`Fragment.onCreate`. If you override this method you*must* call through to the superclass implementation. | Parameters || |----------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `savedInstanceState` | [Bundle](https://developer.android.com/reference/kotlin/android/os/Bundle.html#)?:If the fragment is being re-created from a previous saved state, this is the state.

Unlike[onCreateOptionsMenu](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateOptionsMenu(android.view.Menu,%20android.view.MenuInflater)), this will be called every time the context menu is about to be shown and should be populated for the view (or item inside the view for[AdapterView](https://developer.android.com/reference/kotlin/android/widget/AdapterView.html#)subclasses, this can be found in the`menuInfo`)). Use[onContextItemSelected(android.view.MenuItem)](https://developer.android.com/reference/kotlin/android/app/Fragment#onContextItemSelected(android.view.MenuItem))to know when an item has been selected. The default implementation calls up to[Activity.onCreateContextMenu](https://developer.android.com/reference/kotlin/android/app/Activity#onCreateContextMenu(android.view.ContextMenu,%20android.view.View,%20android.view.ContextMenu.ContextMenuInfo)), though you can not call this implementation if you don't want that behavior. It is not safe to hold onto the context menu after this method returns. Called when the context menu for this view is being built. It is not safe to hold onto the menu after this method returns. | Parameters || |------------|--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `menu` | [ContextMenu](https://developer.android.com/reference/kotlin/android/view/ContextMenu.html#)!:The context menu that is being built | | `v` | [View](https://developer.android.com/reference/kotlin/android/view/View.html#)!:The view for which the context menu is being built | | `menuInfo` | [ContextMenu.ContextMenuInfo](https://developer.android.com/reference/kotlin/android/view/ContextMenu.ContextMenuInfo.html#)!:Extra information about the item for which the context menu should be shown. This information will vary depending on the class of v. | ### onCreateOptionsMenu Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onCreateOptionsMenu(     menu: Menu!,     inflater: MenuInflater! ): Unit ``` **Deprecated:** *Deprecated in Java.* Initialize the contents of the Activity's standard options menu. You should place your menu items in to menu. For this method to be called, you must have first called[setHasOptionsMenu](https://developer.android.com/reference/kotlin/android/app/Fragment#setHasOptionsMenu(kotlin.Boolean)). See[Activity.onCreateOptionsMenu](https://developer.android.com/reference/kotlin/android/app/Activity#onCreateOptionsMenu(android.view.Menu))for more information. | Parameters || |--------|---------------------------------------------------------------------------------------------------------------------------------| | `menu` | [Menu](https://developer.android.com/reference/kotlin/android/view/Menu.html#)!:The options menu in which you place your items. | **See Also** - [#setHasOptionsMenu](https://developer.android.com/reference/kotlin/android/app/Fragment#setHasOptionsMenu(kotlin.Boolean)) - [#onPrepareOptionsMenu](https://developer.android.com/reference/kotlin/android/app/Fragment#onPrepareOptionsMenu(android.view.Menu)) - [#onOptionsItemSelected](https://developer.android.com/reference/kotlin/android/app/Fragment#onOptionsItemSelected(android.view.MenuItem)) ### onCreateView Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onCreateView(     inflater: LayoutInflater!,     container: ViewGroup?,     savedInstanceState: Bundle! ): View? ``` **Deprecated:** *Deprecated in Java.* Called to have the fragment instantiate its user interface view. This is optional, and non-graphical fragments can return null (which is the default implementation). This will be called between[onCreate(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreate(android.os.Bundle))and[onActivityCreated(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onActivityCreated(android.os.Bundle)). If you return a View from here, you will later be called in[onDestroyView](https://developer.android.com/reference/kotlin/android/app/Fragment#onDestroyView())when the view is being released. | Parameters || |----------------------|------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `inflater` | [LayoutInflater](https://developer.android.com/reference/kotlin/android/view/LayoutInflater.html#)!:The LayoutInflater object that can be used to inflate any views in the fragment, | | `container` | [ViewGroup](https://developer.android.com/reference/kotlin/android/view/ViewGroup.html#)?:If non-null, this is the parent view that the fragment's UI should be attached to. The fragment should not add the view itself, but this can be used to generate the LayoutParams of the view. | | `savedInstanceState` | [Bundle](https://developer.android.com/reference/kotlin/android/os/Bundle.html#)!:If non-null, this fragment is being re-constructed from a previous saved state as given here. | | Return || |---------------------------------------------------------------------------------|-------------------------------------------------| | [View](https://developer.android.com/reference/kotlin/android/view/View.html#)? | Return the View for the fragment's UI, or null. | ### onDestroy Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onDestroy(): Unit ``` **Deprecated:** *Deprecated in Java.* Called when the fragment is no longer in use.

This may be called immediately after the fragment is created from a tag in a layout file. Note this is*before* the fragment's[onAttach(android.app.Activity)](https://developer.android.com/reference/kotlin/android/app/Fragment#onAttach(android.app.Activity))has been called; all you should do here is parse the attributes and save them away. This is called every time the fragment is inflated, even if it is being inflated into a new instance with saved state. It typically makes sense to re-parse the parameters each time, to allow them to change with different configurations. Here is a typical implementation of a fragment that can take parameters both through attributes supplied here as well from[getArguments()](https://developer.android.com/reference/kotlin/android/app/Fragment#getArguments()): Note that parsing the XML attributes uses a "styleable" resource. The declaration for the styleable used here is: The fragment can then be declared within its activity's content layout through a tag like this: This fragment can also be created dynamically from arguments given at runtime in the arguments Bundle; here is an example of doing so at creation of the containing activity: If you override this method you*must* call through to the superclass implementation.

This is generally tied to[Activity.onResume](https://developer.android.com/reference/kotlin/android/app/Activity#onResume())of the containing Activity's lifecycle. If you override this method you*must*call through to the superclass implementation. ### onSaveInstanceState Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onSaveInstanceState(outState: Bundle!): Unit ``` **Deprecated:** *Deprecated in Java.* Called to ask the fragment to save its current dynamic state, so it can later be reconstructed in a new instance of its process is restarted. If a new instance of the fragment later needs to be created, the data you place in the Bundle here will be available in the Bundle given to[onCreate(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreate(android.os.Bundle)),[onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateView(android.view.LayoutInflater,%20android.view.ViewGroup,%20android.os.Bundle)), and[onActivityCreated(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onActivityCreated(android.os.Bundle)). This corresponds to[Activity.onSaveInstanceState(Bundle)](https://developer.android.com/reference/kotlin/android/app/Activity#onSaveInstanceState(android.os.Bundle))and most of the discussion there applies here as well. Note however:*this method may be called at any time before[onDestroy()](https://developer.android.com/reference/kotlin/android/app/Fragment#onDestroy())*. There are many situations where a fragment may be mostly torn down (such as when placed on the back stack with no UI showing), but its state will not be saved until its owning activity actually needs to save its state. | Parameters || |------------|------------------------------------------------------------------------------------------------------------------------------| | `outState` | [Bundle](https://developer.android.com/reference/kotlin/android/os/Bundle.html#)!:Bundle in which to place your saved state. | ### onStart Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onStart(): Unit ``` **Deprecated:** *Deprecated in Java.* Called when the Fragment is visible to the user. This is generally tied to[Activity.onStart](https://developer.android.com/reference/kotlin/android/app/Activity#onStart())of the containing Activity's lifecycle. If you override this method you*must*call through to the superclass implementation. ### onStop Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onStop(): Unit ``` **Deprecated:** *Deprecated in Java.* Called when the Fragment is no longer started. This is generally tied to[Activity.onStop](https://developer.android.com/reference/kotlin/android/app/Activity#onStop())of the containing Activity's lifecycle. If you override this method you*must*call through to the superclass implementation. ### onTrimMemory Added in[API level 14](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onTrimMemory(level: Int): Unit ``` **Deprecated:** *Deprecated in Java.* Called when the operating system has determined that it is a good time for a process to trim unneeded memory from its process. You should never compare to exact values of the level, since new intermediate values may be added -- you will typically want to compare if the value is greater or equal to a level you are interested in. To retrieve the processes current trim level at any point, you can use[ActivityManager.getMyMemoryState(RunningAppProcessInfo)](https://developer.android.com/reference/kotlin/android/app/ActivityManager#getMyMemoryState(android.app.ActivityManager.RunningAppProcessInfo)).

This gives subclasses a chance to initialize themselves once they know their view hierarchy has been completely created. The fragment's view hierarchy is not however attached to its parent at this point. | Parameters || |----------------------|---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `view` | [View](https://developer.android.com/reference/kotlin/android/view/View.html#)!:The View returned by[onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateView(android.view.LayoutInflater,%20android.view.ViewGroup,%20android.os.Bundle)). | | `savedInstanceState` | [Bundle](https://developer.android.com/reference/kotlin/android/os/Bundle.html#)?:If non-null, this fragment is being re-constructed from a previous saved state as given here. | ### onViewStateRestored Added in[API level 17](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun onViewStateRestored(savedInstanceState: Bundle!): Unit ``` **Deprecated:** *Deprecated in Java.* Called when all saved state has been restored into the view hierarchy of the fragment. This can be used to do initialization based on saved state that you are letting the view hierarchy track itself, such as whether check box widgets are currently checked. This is called after[onActivityCreated(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onActivityCreated(android.os.Bundle))and before[onStart()](https://developer.android.com/reference/kotlin/android/app/Fragment#onStart()). If you override this method you*must*call through to the superclass implementation. | Parameters || |----------------------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `savedInstanceState` | [Bundle](https://developer.android.com/reference/kotlin/android/os/Bundle.html#)!:If the fragment is being re-created from a previous saved state, this is the state. | ### postponeEnterTransition Added in[API level 26](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun postponeEnterTransition(): Unit ``` **Deprecated:** *Deprecated in Java.* Postpone the entering Fragment transition until[startPostponedEnterTransition()](https://developer.android.com/reference/kotlin/android/app/Fragment#startPostponedEnterTransition())or[FragmentManager.executePendingTransactions()](https://developer.android.com/reference/kotlin/android/app/FragmentManager#executePendingTransactions())has been called. This method gives the Fragment the ability to delay Fragment animations until all data is loaded. Until then, the added, shown, and attached Fragments will be INVISIBLE and removed, hidden, and detached Fragments won't be have their Views removed. The transaction runs when all postponed added Fragments in the transaction have called[startPostponedEnterTransition()](https://developer.android.com/reference/kotlin/android/app/Fragment#startPostponedEnterTransition()). This method should be called before being added to the FragmentTransaction or in[onCreate(android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreate(android.os.Bundle)),[onAttach(android.content.Context)](https://developer.android.com/reference/kotlin/android/app/Fragment#onAttach(android.content.Context)), or[onCreateView(android.view.LayoutInflater,android.view.ViewGroup,android.os.Bundle)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateView(android.view.LayoutInflater,%20android.view.ViewGroup,%20android.os.Bundle))}.[startPostponedEnterTransition()](https://developer.android.com/reference/kotlin/android/app/Fragment#startPostponedEnterTransition())must be called to allow the Fragment to start the transitions. When a FragmentTransaction is started that may affect a postponed FragmentTransaction, based on which containers are in their operations, the postponed FragmentTransaction will have its start triggered. The early triggering may result in faulty or nonexistent animations in the postponed transaction. FragmentTransactions that operate only on independent containers will not interfere with each other's postponement. Calling postponeEnterTransition on Fragments with a null View will not postpone the transition. Likewise, postponement only works if FragmentTransaction optimizations are enabled. **See Also** - [android.app.Activity#postponeEnterTransition()](https://developer.android.com/reference/kotlin/android/app/Activity#postponeEnterTransition()) - [android.app.FragmentTransaction#setReorderingAllowed(boolean)](https://developer.android.com/reference/kotlin/android/app/FragmentTransaction#setReorderingAllowed(kotlin.Boolean)) ### registerForContextMenu Added in[API level 11](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` open fun registerForContextMenu(view: View!): Unit ``` **Deprecated:** *Deprecated in Java.* Registers a context menu to be shown for the given view (multiple views can show the context menu). This method will set the[OnCreateContextMenuListener](https://developer.android.com/reference/kotlin/android/view/View.OnCreateContextMenuListener.html#)on the view to this fragment, so[onCreateContextMenu(android.view.ContextMenu,android.view.View,android.view.ContextMenu.ContextMenuInfo)](https://developer.android.com/reference/kotlin/android/app/Fragment#onCreateContextMenu(android.view.ContextMenu,%20android.view.View,%20android.view.ContextMenu.ContextMenuInfo))will be called when it is time to show the context menu. | Parameters || |--------|---------------------------------------------------------------------------------------------------------------------------| | `view` | [View](https://developer.android.com/reference/kotlin/android/view/View.html#)!:The view that should show a context menu. | **See Also** - [#unregisterForContextMenu(View)](https://developer.android.com/reference/kotlin/android/app/Fragment#unregisterForContextMenu(android.view.View)) ### requestPermissions Added in[API level 23](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) Deprecated in[API level 28](https://developer.android.com/guide/topics/manifest/uses-sdk-element.html#ApiLevels) ``` fun requestPermissions(     permissions: Array,     requestCode: Int ): Unit ``` **Deprecated:** *Deprecated in Java.* Requests permissions to be granted to this application. These permissions must be requested in your manifest, they should not be granted to your app, and they should have protection level[#PROTECTION_DANGEROUS dangerous](https://developer.android.com/reference/kotlin/android/content/pm/PermissionInfo.html#), regardless whether they are declared by the platform or a third-party app. Normal permissions[android.content.pm.PermissionInfo#PROTECTION_NORMAL](https://developer.android.com/reference/kotlin/android/content/pm/PermissionInfo.html#PROTECTION_NORMAL:kotlin.Int)are granted at install time if requested in the manifest. Signature permissions[android.content.pm.PermissionInfo#PROTECTION_SIGNATURE](https://developer.android.com/reference/kotlin/android/content/pm/PermissionInfo.html#PROTECTION_SIGNATURE:kotlin.Int)are granted at install time if requested in the manifest and the signature of your app matches the signature of the app declaring the permissions. Call[shouldShowRequestPermissionRationale(java.lang.String)](https://developer.android.com/reference/kotlin/android/app/Fragment#shouldShowRequestPermissionRationale(kotlin.String))before calling this API to check if the system recommends to show a rationale UI before asking for a permission. If your app does not have the requested permissions the user will be presented with UI for accepting them. After the user has accepted or rejected the requested permissions you will receive a callback on[onRequestPermissionsResult(int,java.lang.String[],int[])](https://developer.android.com/reference/kotlin/android/app/Fragment#onRequestPermissionsResult(kotlin.Int,%20kotlin.Array,%20kotlin.IntArray))reporting whether the permissions were granted or not. Note that requesting a permission does not guarantee it will be granted and your app should be able to run without having this permission. This method may start an activity allowing the user to choose which permissions to grant and which to reject. Hence, you should be prepared that your activity may be paused and resumed. Further, granting some permissions may require a restart of you application. In such a case, the system will recreate the activity stack before delivering the result to[onRequestPermissionsResult(int,java.lang.String[],int[])](https://developer.android.com/reference/kotlin/android/app/Fragment#onRequestPermissionsResult(kotlin.Int,%20kotlin.Array,%20kotlin.IntArray)). When checking whether you have a permission you should use[android.content.Context#checkSelfPermission(String)](https://developer.android.com/reference/kotlin/android/content/Context.html#checkSelfPermission(kotlin.String)). Calling this API for permissions already granted to your app would show UI to the user to decide whether the app can still hold these permissions. This can be useful if the way your app uses data guarded by the permissions changes significantly. You cannot request a permission if your activity sets[noHistory](https://developer.android.com/reference/kotlin/android/R.styleable.html#AndroidManifestActivity_noHistory:kotlin.Int)to`true`because in this case the activity would not receive result callbacks including[onRequestPermissionsResult(int,java.lang.String[],int[])](https://developer.android.com/reference/kotlin/android/app/Fragment#onRequestPermissionsResult(kotlin.Int,%20kotlin.Array,%20kotlin.IntArray)). | Parameters || |---------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `permissions` | [Array](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-array/index.html)\<[String](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-string/index.html)!\>:The requested permissions.
