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

Because IE is the event is the global and Firefox event is local, not very convenient to use, this time we have to assemble their own common event operation, encapsulation into class for easy reuse Copy Code code as follows: /** Class Event Usage: Event.getevent (); Get Ie,firefox Event Event.gettarget () to get IE's srcelement or Firefox target Event.isie (); IE Event.clientx (); Get Ie,fox's Mouse x coordinates Event.clienty (); Gets the mouse y-coordinate of the Ie,fox */
