exiting the device. The initial reason is that the custom ViewGroup customviewabve intercepts the gesture event, so that the subview cannot respond if it fails to accept the event. Then we can go to the source code of the SlidingMenu control and find customviewabve. java, and then we find this method onInterceptTouchEvent (). This method is a method of ViewGroup to trigger onTouchEvent () to this ViewGroup and its various childView () previously, related events were intercepted. if onInterceptT
