Hello， I resolved this issue! Same as my previous post, I put a transparent layout onto the top and make it consume all OnTouchEvent(). After this, other views under this top layout will lost focus when OnTouch happens(It is not I want ); by tracing, I found when Ontouch happen, before OnTouchEvent() is called back, framework will deprive these view's focus which is setFocusableInTouchMode(false); As a result, when all views under this top layout are setFocusableInTouchMode(true); this issue is resolved. OnTouch will not have any influence onto other views' focus! Thank you!
