Classes

ActionBarDrawerToggle This class is deprecated. Please use ActionBarDrawerToggle in support-v7-appcompat.

This class provides a handy way to tie together the functionality of DrawerLayout and the framework ActionBar to implement the recommended design for navigation drawers.

To use ActionBarDrawerToggle, create one in your Activity and call through to the following methods corresponding to your Activity callbacks:

Call syncState() from your Activity's onPostCreate to synchronize the indicator with the state of the linked DrawerLayout after onRestoreInstanceState has occurred.

ActionBarDrawerToggle can be used directly as a DrawerLayout.DrawerListener, or if you are already providing your own listener, call through to each of the listener methods from your own.
