Android Imageview problem

            
ImageView
android: focusableInTouchMode = "true"
src is a selector
Only two properties within the selector
state_focused = true and false, show two pictures

ImageView event
OnclickListener display a Toast

Question:
selector effective, you can switch the picture, but the switch will not respond Onclic first event, the focus must be on ImageView clicking again will respond to events

If ImageView property focusableInTouchMode, then Selector is useless, Toast will display properly, that is a normal event

If OnclickListener changed to OnTouch where Event.ACTION_DOWN words Selector will not use, Toast also normal,

How to solve this problem, the effect is to be achieved when clicked ImageView will replace the background, while responding to the event display Toast
