The support library has been superseded by[AndroidX](https://developer.android.com/jetpack/androidx)which is part of[Jetpack](https://developer.android.com/jetpack). We recommend using the AndroidX libraries in all new projects. You should also consider[migrating](https://developer.android.com/jetpack/androidx/migrate)existing projects to AndroidX. To find the AndroidX class that maps to this deprecated class, see the AndroidX support library[class mappings](https://developer.android.com/jetpack/androidx/migrate/class-mappings). ` public abstract class FragmentTransaction ` ` extends Object `` ` |---|--------------------------------------------| | java.lang.Object || | ↳ | android.support.v4.app.FragmentTransaction |
*** ** * ** *** Static library support version of the framework's[FragmentTransaction](https://developer.android.com/reference/android/app/FragmentTransaction.html). Used to write apps that run on platforms prior to Android 3.0. When running on Android 3.0 or above, this implementation is still used; it does not try to switch to the framework's implementation.

## Public methods ### add added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction add (Fragment fragment, String tag) ``` Calls[add(int, Fragment, String)](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#add(int, android.support.v4.app.Fragment, java.lang.String))with a 0 containerViewId.
| Parameters || |------------|-------------------| | `fragment` | `Fragment`
| | `tag` | `String`
| | Returns || |-----------------------------------------------------------------------------------------------------------|--------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) |
| ### add added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction add (int containerViewId, Fragment fragment, String tag) ``` Add a fragment to the activity state. This fragment may optionally also have its view (if[Fragment.onCreateView](https://developer.android.com/reference/android/support/v4/app/Fragment#onCreateView(android.view.LayoutInflater, android.view.ViewGroup, android.os.Bundle))returns non-null) into a container view of the activity.
| Parameters || |-------------------|----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `containerViewId` | `int`: Optional identifier of the container this fragment is to be placed in. If 0, it will not be placed in a container.
| | `fragment` | `Fragment`: The fragment to be added. This fragment must not already be added to the activity.
| | `tag` | `String`: Optional tag name for the fragment, to later retrieve the fragment with[FragmentManager.findFragmentByTag(String)](https://developer.android.com/reference/android/support/v4/app/FragmentManager#findFragmentByTag(java.lang.String)).
| | Returns || |-----------------------------------------------------------------------------------------------------------|-------------------------------------------------------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) | Returns the same FragmentTransaction instance.
| ### add added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction add (int containerViewId, Fragment fragment) ``` Calls[add(int, Fragment, String)](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#add(int, android.support.v4.app.Fragment, java.lang.String))with a null tag.
| Parameters || |-------------------|-------------------| | `containerViewId` | `int`
| | `fragment` | `Fragment`
| | Returns || |-----------------------------------------------------------------------------------------------------------|--------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) |
| ### addSharedElement added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction addSharedElement (View sharedElement, String name) ``` Used with custom Transitions to map a View from a removed or hidden Fragment to a View from a shown or added Fragment.sharedElementmust have a unique transitionName in the View hierarchy.
| Parameters || |-----------------|---------------------------------------------------------------------------------------------------------| | `sharedElement` | `View`: A View in a disappearing Fragment to match with a View in an appearing Fragment.
| | `name` | `String`: The transitionName for a View in an appearing Fragment to match to the shared element.
| | Returns || |-----------------------------------------------------------------------------------------------------------|--------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) |
| **See also:** - [setSharedElementReturnTransition(Object)](https://developer.android.com/reference/android/support/v4/app/Fragment#setSharedElementReturnTransition(java.lang.Object)) - [setSharedElementEnterTransition(Object)](https://developer.android.com/reference/android/support/v4/app/Fragment#setSharedElementEnterTransition(java.lang.Object)) ### addToBackStack added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction addToBackStack (String name) ``` Add this transaction to the back stack. This means that the transaction will be remembered after it is committed, and will reverse its operation when later popped off the stack.
| Parameters || |--------|-----------------------------------------------------------------------| | `name` | `String`: An optional name for this back stack state, or null.
| | Returns || |-----------------------------------------------------------------------------------------------------------|--------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) |
| ### attach added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction attach (Fragment fragment) ``` Re-attach a fragment after it had previously been detached from the UI with[detach(Fragment)](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#detach(android.support.v4.app.Fragment)). This causes its view hierarchy to be re-created, attached to the UI, and displayed.
| Parameters || |------------|-------------------------------------------------| | `fragment` | `Fragment`: The fragment to be attached.
| | Returns || |-----------------------------------------------------------------------------------------------------------|-------------------------------------------------------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) | Returns the same FragmentTransaction instance.
| ### commit added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int commit () ``` Schedules a commit of this transaction. The commit does not happen immediately; it will be scheduled as work on the main thread to be done the next time that thread is ready. A transaction can only be committed with this method prior to its containing activity saving its state. If the commit is attempted after that point, an exception will be thrown. This is because the state after the commit can be lost if the activity needs to be restored from its state. See[commitAllowingStateLoss()](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#commitAllowingStateLoss())for situations where it may be okay to lose the commit.

| Returns || |-------|-----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | `int` | Returns the identifier of this transaction's back stack entry, if[addToBackStack(String)](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#addToBackStack(java.lang.String))had been called. Otherwise, returns a negative number.
| ### commitAllowingStateLoss added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` int commitAllowingStateLoss () ``` Like[commit()](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#commit())but allows the commit to be executed after an activity's state is saved. This is dangerous because the commit can be lost if the activity needs to later be restored from its state, so this should only be used for cases where it is okay for the UI state to change unexpectedly on the user.
| Returns || |-------|--------| | `int` |
| ### commitNow added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void commitNow () ``` Commits this transaction synchronously. Any added fragments will be initialized and brought completely to the lifecycle state of their host and any removed fragments will be torn down accordingly before this call returns. Committing a transaction in this way allows fragments to be added as dedicated, encapsulated components that monitor the lifecycle state of their host while providing firmer ordering guarantees around when those fragments are fully initialized and ready. Fragments that manage views will have those views created and attached. Calling`commitNow`is preferable to calling[commit()](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#commit())followed by[executePendingTransactions()](https://developer.android.com/reference/android/support/v4/app/FragmentManager#executePendingTransactions())as the latter will have the side effect of attempting to commit*all*currently pending transactions whether that is the desired behavior or not. Transactions committed in this way may not be added to the FragmentManager's back stack, as doing so would break other expected ordering guarantees for other asynchronously committed transactions. This method will throw[IllegalStateException](https://developer.android.com/reference/java/lang/IllegalStateException)if the transaction previously requested to be added to the back stack with[addToBackStack(String)](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#addToBackStack(java.lang.String)). A transaction can only be committed with this method prior to its containing activity saving its state. If the commit is attempted after that point, an exception will be thrown. This is because the state after the commit can be lost if the activity needs to be restored from its state. See[commitAllowingStateLoss()](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#commitAllowingStateLoss())for situations where it may be okay to lose the commit.

### commitNowAllowingStateLoss added in[version 24.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` void commitNowAllowingStateLoss () ``` Like[commitNow()](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#commitNow())but allows the commit to be executed after an activity's state is saved. This is dangerous because the commit can be lost if the activity needs to later be restored from its state, so this should only be used for cases where it is okay for the UI state to change unexpectedly on the user.
### detach added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction detach (Fragment fragment) ``` Detach the given fragment from the UI. This is the same state as when it is put on the back stack: the fragment is removed from the UI, however its state is still being actively managed by the fragment manager. When going into this state its view hierarchy is destroyed.
| Parameters || |------------|-------------------------------------------------| | `fragment` | `Fragment`: The fragment to be detached.
| | Returns || |-----------------------------------------------------------------------------------------------------------|-------------------------------------------------------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) | Returns the same FragmentTransaction instance.
| ### disallowAddToBackStack added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction disallowAddToBackStack () ``` Disallow calls to[addToBackStack(String)](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#addToBackStack(java.lang.String)). Any future calls to addToBackStack will throw[IllegalStateException](https://developer.android.com/reference/java/lang/IllegalStateException). If addToBackStack has already been called, this method will throw IllegalStateException.
| Returns || |-----------------------------------------------------------------------------------------------------------|--------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) |
| ### hide added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction hide (Fragment fragment) ``` Hides an existing fragment. This is only relevant for fragments whose views have been added to a container, as this will cause the view to be hidden.

| ### runOnCommit added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction runOnCommit (Runnable runnable) ``` Add a Runnable to this transaction that will be run after this transaction has been committed. If fragment transactions are[optimized](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#setReorderingAllowed(boolean))this may be after other subsequent fragment operations have also taken place, or operations in this transaction may have been optimized out due to the presence of a subsequent fragment transaction in the batch. If a transaction is committed using[commitAllowingStateLoss()](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#commitAllowingStateLoss())this runnable may be executed when the FragmentManager is in a state where new transactions may not be committed without allowing state loss. `runOnCommit`may not be used with transactions[added to the back stack](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#addToBackStack(java.lang.String))as Runnables cannot be persisted with back stack state.[IllegalStateException](https://developer.android.com/reference/java/lang/IllegalStateException)will be thrown if[addToBackStack(String)](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#addToBackStack(java.lang.String))has been previously called for this transaction or if it is called after a call to`runOnCommit`.

| ### setPrimaryNavigationFragment added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction setPrimaryNavigationFragment (Fragment fragment) ``` Set a currently active fragment in this FragmentManager as the primary navigation fragment. The primary navigation fragment's[child FragmentManager](https://developer.android.com/reference/android/support/v4/app/Fragment#getChildFragmentManager())will be called first to process delegated navigation actions such as[popBackStack()](https://developer.android.com/reference/android/support/v4/app/FragmentManager#popBackStack())if no ID or transaction name is provided to pop to. Navigation operations outside of the fragment system may choose to delegate those actions to the primary navigation fragment as returned by[getPrimaryNavigationFragment()](https://developer.android.com/reference/android/support/v4/app/FragmentManager#getPrimaryNavigationFragment()). The fragment provided must currently be added to the FragmentManager to be set as a primary navigation fragment, or previously added as part of this transaction.

| Parameters || |------------|---------------------------------------------------------------------------| | `fragment` | `Fragment`: the fragment to set as the primary navigation fragment
| | Returns || |-----------------------------------------------------------------------------------------------------------|----------------------------------------------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) | the same FragmentTransaction instance
| ### setReorderingAllowed added in[version 26.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction setReorderingAllowed (boolean reorderingAllowed) ``` Sets whether or not to allow optimizing operations within and across transactions. This will remove redundant operations, eliminating operations that cancel. For example, if two transactions are executed together, one that adds a fragment A and the next replaces it with fragment B, the operations will cancel and only fragment B will be added. That means that fragment A may not go through the creation/destruction lifecycle. The side effect of removing redundant operations is that fragments may have state changes out of the expected order. For example, one transaction adds fragment A, a second adds fragment B, then a third removes fragment A. Without removing the redundant operations, fragment B could expect that while it is being created, fragment A will also exist because fragment A will be removed after fragment B was added. With removing redundant operations, fragment B cannot expect fragment A to exist when it has been created because fragment A's add/remove will be optimized out. It can also reorder the state changes of Fragments to allow for better Transitions. Added Fragments may have[onCreate(Bundle)](https://developer.android.com/reference/android/support/v4/app/Fragment#onCreate(android.os.Bundle))called before replaced Fragments have[onDestroy()](https://developer.android.com/reference/android/support/v4/app/Fragment#onDestroy())called. [postponeEnterTransition()](https://developer.android.com/reference/android/support/v4/app/Fragment#postponeEnterTransition())requires`setReorderingAllowed(true)`. The default is`false`.
| Parameters || |---------------------|---------------------------------------------------------------------------------------------------------------------------------------------------| | `reorderingAllowed` | `boolean`:`true`to enable optimizing out redundant operations or`false`to disable optimizing out redundant operations on this transaction.
| | Returns || |-----------------------------------------------------------------------------------------------------------|--------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) |
| ### setTransition added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction setTransition (int transit) ``` Select a standard transition animation for this transaction. May be one of[TRANSIT_NONE](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#TRANSIT_NONE),[TRANSIT_FRAGMENT_OPEN](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#TRANSIT_FRAGMENT_OPEN),[TRANSIT_FRAGMENT_CLOSE](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#TRANSIT_FRAGMENT_CLOSE), or[TRANSIT_FRAGMENT_FADE](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction#TRANSIT_FRAGMENT_FADE).

| | Returns || |-----------------------------------------------------------------------------------------------------------|--------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) |
| ### show added in[version 22.1.0](https://developer.android.com/topic/libraries/support-library/revisions) ``` FragmentTransaction show (Fragment fragment) ``` Shows a previously hidden fragment. This is only relevant for fragments whose views have been added to a container, as this will cause the view to be shown.
| Parameters || |------------|----------------------------------------------| | `fragment` | `Fragment`: The fragment to be shown.
| | Returns || |-----------------------------------------------------------------------------------------------------------|-------------------------------------------------------| | [FragmentTransaction](https://developer.android.com/reference/android/support/v4/app/FragmentTransaction) | Returns the same FragmentTransaction instance.
