This is the simplest way that I designed. Try this.
dependencies
-
implementation ‘androidx.appcompat:appcompat:1.3.0-beta01’
-
implementation ‘androidx.cardview:cardview:1.0.0’
<android.support.v7.widget.CardView android:layout_width="80dp" android:layout_height="80dp" android:elevation="12dp" android:id="@+id/view2" app:cardCornerRadius="40dp" android:layout_centerHorizontal="true" android:innerRadius="0dp" android:shape="ring" android:thicknessRatio="1.9"> <ImageView android:layout_height="80dp" android:layout_width="match_parent" android:id="@+id/imageView1" android:src="@drawable/YOUR_IMAGE" android:layout_alignParentTop="true" android:layout_centerHorizontal="true"> </ImageView> </android.support.v7.widget.CardView>
If you are working on android versions above lollipop
<android.support.v7.widget.CardView android:layout_width="80dp" android:layout_height="80dp" android:elevation="12dp" android:id="@+id/view2" app:cardCornerRadius="40dp" android:layout_centerHorizontal="true"> <ImageView android:layout_height="80dp" android:layout_width="match_parent" android:id="@+id/imageView1" android:src="@drawable/YOUR_IMAGE" android:scaleType="centerCrop"/> </android.support.v7.widget.CardView>
Adding Border to round ImageView – LATEST VERSION
Wrap it with another CardView slightly bigger than the inner one and set its background color to add a border to your round image. You can increase the size of the outer CardView to increase the thickness of the border.
<androidx.cardview.widget.CardView
android:layout_width="155dp"
android:layout_height="155dp"
app:cardCornerRadius="250dp"
app:cardBackgroundColor="@color/white">
<androidx.cardview.widget.CardView
android:layout_width="150dp"
android:layout_height="150dp"
app:cardCornerRadius="250dp"
android:layout_gravity="center">
<ImageView
android:layout_width="150dp"
android:layout_height="150dp"
android:src="@drawable/default_user"
android:scaleType="centerCrop"/>
</androidx.cardview.widget.CardView>
