Why is a button clickable when theres another layout overlaying it?

Question

I got a Layout which is relatively positioned. In it I got (by now) two things:

• A Clickable Button which is bound to an onClick-Event
• A LinearLayout which is overlaying the full screen

Although the LinearLayout is overlaying the button, the button is still clickable. Even if there's another button in the overlay.

How can I avoid this?

Answer 1

The overlaying views (and layouts) have to implement an onClick listener to catch the event, otherwise the event is dispatched on the underlaying views.
