this article is to customize a viewgroup, wrapped around the original ListView, and placed on this particular interface. Since event distribution is performed at a level, we can override the dispatchtouchevent method of this outer layer of custom ViewGroup to implement an event distribution mechanism that controls all child view This allows us to implement the response mechanism of the touch events we want in this particular interface.Write a custom framelayout called interceptorframelayout, ov

, all the events of the component must be handled by ourselves. In this case, we also need to handle the event. therefore: because of the two situations mentioned above, we have to handle the event on our own. 2. with the motivation to process events, we need to understand how the android system handles complex events. the android system provides three related methods for all events. The following uses Touch events as an example to describe. The three methods are: DispatchTouchEvent (MotionEvent

Android development-touch Event Processing MechanismAndroid touch message transmission mechanismEach user touch (onClick, onLongClick, onScroll, etc .) it is composed of one ACTION_DOWN + n ACTION_MOVE + 1 ACTION_UP. A user must first have an ACTION_DOWN response when touching the user, and there must be an ACTION_UP when touching the user. (Of course, if it is intercepted on the way, it may not exist !) So how does View distribute messages and intercept messages?1. View and its subclass have tw
