Use it only on xml file layout.
Replace for example :
<Imageview
android:layout_width="source_width"
android:layout_height="source_height"
android:scaleType="centerCrop"
android:contentDescription="@null"
android:src="your_source"/>
By :
<fr.futurdigital.apps.android.circleimageview.CircleImageView
android:layout_width="source_width"
android:layout_height="source_height"
android:contentDescription="@null"
android:src="your_source"
custom:fill_color="#FFF"/>
Note : has only one custom attribut to set on xml -> if image is too small, we fill empty space with color chosen
See result :
