How to remove ImageButton's standard background image?

Question

In ImageButton I want to remove the standard button background image. In http://developer.android.com it is said, that one must define his\her own background image or set the background color to be transparent. I tried to set a black background, but it didn't make any effect...

Answer 1

You can use android:background="@null" for your ImageButton.

Answer 2

The best choice is not set a transparent background to your ImageButton.

Give to your user a feedback when the button is tapped.

android:background="?attr/selectableItemBackgroundBorderless"
