I have a container ViewGroup, lets call it screen inside a ScrollView. This container view hosts a number of other Views let's call them widgets, and some of them are interested in preventing the ScrollView from scrolling and using the MotionEvent theirselves (for example a pannable image)
I can't figure out the proper event intercept strategy to use. ScrollView always processes the event before the children, or the children process the event but scrollview is disabled.
I read about issuing getParent().requestDisableInterceptTouchEvent() in the child views if this view wants to capture the event, but their onTouchEvent is not called, I suppose because ScrollView has engulfed the event beforehand. I guess the fact that I have 2 levels of layers (container + widgets) prevents this from working, I suppose the container ViewGroup has to play an important part here, but I can't figure out which one...
Can I know, at the ScrollView's onInterceptTouchEvent level, which widget on the container viewGroup has been touched to decide if I should intercept or not?
or...
How can the 'widget' layers in the ViewGroup get the event before ScrollView so I can call getParent().onRequestDisableInterceptTouch() ... or is it getParent().getParent().onRequestDisableInterceptTouch()?
Thanks in advance
