Welcome all
I'm developing an augmented reality app that consists in a camera view with
some linear layouts on the screen representing the position of a POI in the
camera.
The LinearLayouts contains some view elements that implements
onTouchListener and have the action to open a new activity when ACTION_UP
event is called.
The problem is that ACTION_UP is never called. When i press on one of the
POIs on the camera screen, the element calls ACTION_DOWN and instantly
after that, ACTION_CANCEL is being called.
I read that ACTION_CANCEL occurs when the parent takes possession of the
motion, for example when the user has dragged enough across a list view
that it will start scrolling instead of letting you press the buttons
inside of it. You can find out more about it at the viewgroup documentation
of onInterceptTouchEvent.
The problem is that i dont understand what i'm doing wrong.
This is my code of the ontouch in the element that it is displayed on the
linearlayout representing a POI on the camera AR View:
public class Element implements OnTouchListener{...
@Override
public boolean onTouch(View v, MotionEvent event) {
if( event.getAction() == MotionEvent.ACTION_DOWN){
return true;
}else if( event.getAction() == MotionEvent.ACTION_UP){
parent.doAction(this.action);
return true;
}else if(event.getAction() == MotionEvent.ACTION_MOVE){
return true;
} else if(event.getAction() == MotionEvent.ACTION_CANCEL){
return true;
}
return true;
}
Thanks
