How to have a transparent ImageButton: Android

DON'T USE A TRANSAPENT OR NULL LAYOUT because then the button (or the generic view) will no more highlight at click!!!

I had the same problem and finally I found the correct attribute from Android API to solve the problem. It can apply to any view.

Use this in the button specifications:

android:background="?android:selectableItemBackground"

Try using null for the background ...

android:background="@null"
