Override View.drawableStateChanged to detect state_pressed

Browse source 
Unlike on JB, View.setPressed(boolean) is never called when the view
is pressed on ICS. To detect a pressed state of the view, we need to
override View.drawableStateChanged() and check the drawable state
contains state_pressed.
