For apps developing against android.os.Build.VERSION_CODES#HONEYCOMB or later, tabs are typically presented in the UI using the new ActionBar.newTab() and related APIs for placing tabs within their action bar area.

Protected methods

onSaveInstanceState

protected open fun 
        onSaveInstanceState
(outState: Bundle!): Unit

Deprecated:

This class was deprecated in API level 21.

Called to retrieve per-instance state from an activity before being killed so that the state can be restored in #onCreate or #onRestoreInstanceState (the Bundle populated by this method will be passed to both).

This method is called before an activity may be killed so that when it comes back some time in the future it can restore its state. For example, if activity B is launched in front of activity A, and at some point activity A is killed to reclaim resources, activity A will have a chance to save the current state of its user interface via this method so that when the user returns to activity A, the state of the user interface can be restored via #onCreate or #onRestoreInstanceState.

Do not confuse this method with activity lifecycle callbacks such as #onPause, which is always called when an activity is being placed in the background or on its way to destruction, or #onStop which is called before destruction. One example of when #onPause and #onStop is called and not this method is when a user navigates back from activity B to activity A: there is no need to call #onSaveInstanceState on B because that particular instance will never be restored, so the system avoids calling it. An example when #onPause is called and not #onSaveInstanceState is when activity B is launched in front of activity A: the system may avoid calling #onSaveInstanceState on activity A if it isn't killed during the lifetime of B since the state of the user interface of A will stay intact.

The default implementation takes care of most of the UI per-instance state for you by calling android.view.View#onSaveInstanceState() on each view in the hierarchy that has an id, and by saving the id of the currently focused view (all of which is restored by the default implementation of #onRestoreInstanceState). If you override this method to save additional information not captured by each individual view, you will likely want to call through to the default implementation, otherwise be prepared to save all of the state of each view yourself.

If called, this method will occur after #onStop for applications targeting platforms starting with android.os.Build.VERSION_CODES#P. For applications targeting earlier platform versions this method will occur before #onStop and there are no guarantees about whether it will occur before or after #onPause.

Parameters
outState Bundle!: Bundle in which to place your saved state.

onChildTitleChanged

protected open fun 
        onChildTitleChanged
(childActivity: Activity!, title: CharSequence!): Unit

Deprecated:

This class was deprecated in API level 21.

onPostCreate

protected open fun 
        onPostCreate
(icicle: Bundle?): Unit

Deprecated:

This class was deprecated in API level 21.

Called when activity start-up is complete (after #onStart and #onRestoreInstanceState have been called). Applications will generally not implement this method; it is intended for system classes to do final initialization after application code has run.

Derived classes must call through to the super class's implementation of this method. If they do not, an exception will be thrown.


If you override this method you must call through to the superclass implementation.
Parameters
savedInstanceState Bundle?: If the activity is being re-initialized after previously being shut down then this Bundle contains the data it most recently supplied in #onSaveInstanceState. Note: Otherwise it is null. This value may be null.

onRestoreInstanceState

protected open fun 
        onRestoreInstanceState
(state: Bundle!): Unit

Deprecated:

This class was deprecated in API level 21.

This method is called after #onStart when the activity is being re-initialized from a previously saved state, given here in savedInstanceState. Most implementations will simply use #onCreate to restore their state, but it is sometimes convenient to do it here after all of the initialization has been done or to allow subclasses to decide whether to use your default implementation. The default implementation of this method performs a restore of any view state that had previously been frozen by #onSaveInstanceState.

This method is called between #onStart and #onPostCreate.

Parameters
savedInstanceState Bundle!: the data most recently supplied in #onSaveInstanceState.
