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 constructors

FragmentTransaction()

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, String tag)

Add a fragment to the activity state.

abstract FragmentTransaction add(int containerViewId, Fragment fragment)

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

abstract 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.

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 remove(Fragment fragment)

Remove an existing fragment.

abstract FragmentTransaction replace(int containerViewId, Fragment fragment, String tag)

Replace an existing fragment that was added to a container.

abstract FragmentTransaction replace(int containerViewId, Fragment fragment)

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

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.

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

FragmentTransaction

add

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.
