Did you add clickable=true to your View?

[android-developers] Re: Missing ACTION_UP
So I set an onClickListener for the view and got the correct behavior. I do the highlight background in the onTouchEvent and then remove the background in the onClickListener. It's not pretty, but I don't see any other way, since ACTION_UP never seems to occur. However, this creates another problem. The view is swallowing the click and I want it passed up to the parent for other processing. Is there a method I can call in the onClickListener to cause the click to be passed up the view stack rather than consumed? -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Missing ACTION_UP
It's unfortunate that onClick and onTouch do not use the same approach, where the method returns a true if it handled the event and the parent shouldn't get the event a false if the parent should get the event. -- You received this message because you are subscribed to the Google Groups Android Developers group.

Well, if the docs say it clearly, its fine I guess.

[android-developers] Re: Missing ACTION_UP
True, except the inconsistency results in an incompleteness. The onClick documentation doesn't state what mechanism has been created in the onClick case to produce the same effect as returning a false in the onTouch case.

[android-developers] Re: Missing ACTION_UP
It occurs to me that this may be a consequence of the _kind_ of view I'm using. In this case, it's a TextView. I notice that the only onTouch event that the default TextView passes to my onTouch method is ACTION_DOWN. I'm guessing I need to set some flags elsewhere to get other events for this type of view. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Missing ACTION_UP
Scanning through the TextView docs did not reveal any flags that I think would effect whether or not the ACTION_UP event was passed to onTouch. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Missing ACTION_UP
Now here's an AMAZING thing. When I change onTouch to return true (indicating that the event is handled) then the ACTION_UP event _is_ passed to onTouch. So returning false as a result of the ACTION_DOWN somehow tells the stack to pass the subsequent ACTION_UP to onTouch. This is not a fix, however, since I need to pass the event to the upper view layers for other processing. -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Missing ACTION_UP
It looks like the only workaround is brute force. I can extend TextView to add a myParentView variable and then call the myParentView.onTouchEvent. Of course I'll also return true from onTouch so that I will successfully receive the ACTION_UP event. But what a hack! -- You received this message because you are subscribed to the Google Groups Android Developers group.

[android-developers] Re: Missing ACTION_UP
OK, just for the reference of others, there's the fix, which works.
Returning true means the subsequent ACTION_UP is received. calling the
onTouchEvent method of the parent ensures that the event gets passed
up the stack. Of course, there's another method to set myParent.
@Override
public boolean onTouch(View
arg0, MotionEvent event) {
switch(
event.getAction() ){
case
MotionEvent.ACTION_DOWN:
setBackgroundResource(R.color.on_touch_orange);
break;
case
MotionEvent.ACTION_UP:
setBackgroundResource(0);
break;
}
if( myParent != null ) {
myParent.onTouchEvent(event);
}
return true;
}} );

I don't know why you had a problem with this in the first place. I have custom views where I override the OnTouch and I get ACTION_DOWN and ACTION_UP messages just fine. Also, why do you want to pass the message to the parent anyway?
