FragmentTransaction

Bit mask that is set for all enter transitions.

Bit mask that is set for all exit transitions.

Fragment is being removed from the stack

Fragment should simply fade in or out; that is, no strong navigation associated with it except that it is appearing or disappearing for some reason.

Fragment is being added onto the stack

No animation for transition.

Not set up for a transition.

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

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

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.

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.

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

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() for situations where it may be okay to lose the commit.

Like 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.

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.

Disallow calls to addToBackStack(String). Any future calls to addToBackStack will throw IllegalStateException. If addToBackStack has already been called, this method will throw IllegalStateException.

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.

Returns true if this FragmentTransaction is allowed to be added to the back stack. If this method would return false, addToBackStack(String) will throw IllegalStateException.

Remove an existing fragment. If it was added to a container, its view is also removed from that container.

Replace an existing fragment that was added to a container. This is essentially the same as calling remove(Fragment) for all currently added fragments that were added with the same containerViewId and then add(int, Fragment, String) with the same arguments given here.

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

Set the short title to show as a bread crumb when this transaction is on the back stack, as used by FragmentBreadCrumbs.

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.

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.

Set the full title to show as a bread crumb when this transaction is on the back stack, as used by FragmentBreadCrumbs.

Set specific animation resources to run for the fragments that are entering and exiting in this transaction. The popEnter and popExit animations will be played for enter/exit operations specifically when popping the back stack.

Set specific animation resources to run for the fragments that are entering and exiting in this transaction. These animations will not be played when popping the back stack.

Select a standard transition animation for this transaction. May be one of TRANSIT_NONE, TRANSIT_FRAGMENT_OPEN, or TRANSIT_FRAGMENT_CLOSE

Set a custom style resource that will be used for resolving transit animations.

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.
