Left-right arrow indicators over a ViewPager

Question

I want to show left and right arrows over my ViewPager, to indicate swiping.

I added two ImageButtons over the ViewPager-element but those areas then block the ViewPager

Answer 1

I figured out a solution. It's very simple.

Instead of using ImageButtons for displaying the arrows, I now use ImageViews because they pass on any touch events to the layer underneath.

Then, I put transparent Buttons on the fragments themselves instead, that way they won't block the ViewPagers swiping behaviour but they will fire onClick Events!
