My Activity has a listView with an ActionBar. When the list item is long clicked, it will trigger the contextual action mode. However, the action mode will be lost during the screen rotation.
I know I can restore the state by re-triggerring the Action mode in onsaveInstanceState/restoreInstancestate methods. But I wondering is there any built-in method in Action mode to restore its state?
Thanks!
Declaring android:configChanges in AndroidManifest.xml will instruct Activity Manager to not recreating your activity (default behavior) for those config changes, in which case your action bar state will be reset.
android:configChanges="orientation|screenSize"
By default, this declaration will route the next lifecycle callback to onConfigurationChanged(), then onResume().
If your application doesn't need to update resources during a specific configuration change and you have a performance limitation that requires you to avoid the activity restart, then you can declare that your activity handles the configuration change itself, which prevents the system from restarting your activity.
