FragmentTransaction

public abstract class FragmentTransaction
extends Object

java.lang.Object
↳	android.support.v4.app.FragmentTransaction

Static library support version of the framework's FragmentTransaction. 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. See the framework SDK documentation for a class overview.

Public methods
`abstract FragmentTransaction`	`add(Fragment fragment, String tag)` Calls `add(int, Fragment, String)` with a 0 containerViewId.

`abstract FragmentTransaction`	`add(int containerViewId, Fragment fragment)` Calls `add(int, Fragment, String)` with a null tag.

`abstract FragmentTransaction`	`addToBackStack(String name)` Add this transaction to the back stack.
`abstract FragmentTransaction`	`attach(Fragment fragment)` Re-attach a fragment after it had previously been detached from the UI with `detach(Fragment)`.
`abstract int`	`commit()` Schedules a commit of this transaction.
`abstract int`	`commitAllowingStateLoss()` Like `commit()` but allows the commit to be executed after an activity's state is saved.
`abstract void`	`commitNow()` Commits this transaction synchronously.
`abstract void`	`commitNowAllowingStateLoss()` Like `commitNow()` but allows the commit to be executed after an activity's state is saved.
`abstract FragmentTransaction`	`detach(Fragment fragment)` Detach the given fragment from the UI.
`abstract FragmentTransaction`	`disallowAddToBackStack()` Disallow calls to `addToBackStack(String)`.
`abstract FragmentTransaction`	`hide(Fragment fragment)` Hides an existing fragment.
`abstract boolean`	`isAddToBackStackAllowed()` Returns true if this FragmentTransaction is allowed to be added to the back stack.
`abstract boolean`	`isEmpty()`

`abstract FragmentTransaction`	`runOnCommit(Runnable runnable)` Add a Runnable to this transaction that will be run after this transaction has been committed.
`abstract FragmentTransaction`	`setAllowOptimization(boolean allowOptimization)` This method was deprecated in API level 26.1.0. This has been renamed `setReorderingAllowed(boolean)`.
`abstract FragmentTransaction`	`setBreadCrumbShortTitle(int res)` Set the short title to show as a bread crumb when this transaction is on the back stack.
`abstract FragmentTransaction`	`setBreadCrumbShortTitle(CharSequence text)` Like `setBreadCrumbShortTitle(int)` but taking a raw string; this method is not recommended, as the string can not be changed later if the locale changes.
`abstract FragmentTransaction`	`setBreadCrumbTitle(int res)` Set the full title to show as a bread crumb when this transaction is on the back stack.
`abstract FragmentTransaction`	`setBreadCrumbTitle(CharSequence text)` Like `setBreadCrumbTitle(int)` but taking a raw string; this method is not recommended, as the string can not be changed later if the locale changes.
`abstract FragmentTransaction`	`setCustomAnimations(int enter, int exit, int popEnter, int popExit)` Set specific animation resources to run for the fragments that are entering and exiting in this transaction.
`abstract FragmentTransaction`	`setCustomAnimations(int enter, int exit)` Set specific animation resources to run for the fragments that are entering and exiting in this transaction.
`abstract FragmentTransaction`	`setPrimaryNavigationFragment(Fragment fragment)` Set a currently active fragment in this FragmentManager as the primary navigation fragment.
`abstract FragmentTransaction`	`setReorderingAllowed(boolean reorderingAllowed)` Sets whether or not to allow optimizing operations within and across transactions.
`abstract FragmentTransaction`	`setTransition(int transit)` Select a standard transition animation for this transaction.
`abstract FragmentTransaction`	`setTransitionStyle(int styleRes)` Set a custom style resource that will be used for resolving transit animations.
`abstract FragmentTransaction`	`show(Fragment fragment)` Shows a previously hidden fragment.

Public methods

add

added in version 22.1.0

FragmentTransaction add (Fragment fragment, 
                String tag)

Calls add(int, Fragment, String) with a 0 containerViewId.

Parameters
`fragment`	`Fragment`
`tag`	`String`

Returns
`FragmentTransaction`

add

added in version 22.1.0

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 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)`.

Returns
`FragmentTransaction`	Returns the same FragmentTransaction instance.

add

added in version 22.1.0

FragmentTransaction add (int containerViewId, 
                Fragment fragment)

Calls add(int, Fragment, String) with a null tag.

Parameters
`containerViewId`	`int`
`fragment`	`Fragment`

Returns
`FragmentTransaction`

addSharedElement

added in version 22.1.0

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. sharedElement must 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`

addToBackStack

added in version 22.1.0

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`

attach

added in version 22.1.0

FragmentTransaction attach (Fragment fragment)

Re-attach a fragment after it had previously been detached from the UI with detach(Fragment). This causes its view hierarchy to be re-created, attached to the UI, an
