Android on Drawer Closed Listener

When you setup the ActionBarDrawerToggle you can “implement” the onDrawerClosed and onDrawerOpened callbacks. See the following example from the Docs:

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout,
            R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close) {

        /** Called when a drawer has settled in a completely closed state. */
        public void onDrawerClosed(View view) {
            super.onDrawerClosed(view);
            // Do whatever you want here
        }

        /** Called when a drawer has settled in a completely open state. */
        public void onDrawerOpened(View drawerView) {
            super.onDrawerOpened(drawerView);
            // Do whatever you want here
        }
    };
// Set the drawer toggle as the DrawerListener
mDrawerLayout.addDrawerListener(mDrawerToggle);

Edit: Now the setDrawerListener is deprecated, use addDrawerListener instead.
