How to set Circular Image View Background black in android?

Image View background reflect only inside the circle not outside the circle. I tried so many things but not able do that. Anybody please me. Thanks!!

Solution

Make an .xml file in drawable folder with this content:

<?xml version="1.0" encoding="utf-8"?>
<shape
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:shape="oval">
     <solid
        android:color="@color/black"/>
</shape>

Then set this file as your background.
