- > TestViewRoot:dispatchTouchEvent (ActionDown)
->TestViewRoot:onInterceptTouchEvent (ActionDown)
->TestView:dispathTouchEvent (ActionDown)
->ManActivity:Testview OnTouchListener onTouch (ActionDown)
->TestView:onTouchEvent (ActionDown)
->MainActivity:dispatchTouchEvent (ActionUp)
->TestViewRoot:dispathcTouchEvent (ActionUp)
->TestViewRoot:onInterceptTouchEvent (ActionUp)
->TestView:dispatchTouchEvent (ActionUp)
->MainActivity: TestView onTouchListener onTouch (ActionUp)
-> TestView:onTouchEvent
->MainAvtivity: TestView onClickListener onClick
if TestViewRoot:onInterceptTouchEvent return true;
log below:
MainActivity:dispatchTouchEvent (ActionDown)
->TestViewRoot :dispatchTouchEvent (ActionDown)
->TestViewRoot onInterceptTouchEvent (ActionDown)
-> TestViewRoot onTouchEvent (ActiondonDown)
->MainActivity: onTouchEnvent (ActionDown)
->MainActivity: dispatchTouchEvent (ActionUp)
->MainActivity:onTouchEvent (ActonUp)
