Android Button Tooltip
Is there any way to construct a view where a Button exists on top of another Button? Each button would need to have their own distinct onClick listeners.
The image below shows an iOS version of what I’m trying to achieve in Android.
The “i” portion is another image and shows a tooltip of sorts. The view is currently a LinearLayout.

Yes, it is very easy. Start with a RelativeLayout, or similar, and proceed as normal.
