ImageView in circular through xml

Question

I'd Like to make any image from my ImageView to be circular with a border.

I searched but couldn't find any useful information (anything that I tried didn't work).

How can I achieve this through xml: Create an ImageView with certain src and make it circular with a border?

Answer 1

This is the simplest way that I designed. Try this.

dependencies: compile 'com.android.support:appcompat-v7:23.1.1'
              compile 'com.android.support:design:23.1.1'
              compile 'com.android.support:cardview-v7:23.1.1'

<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 colour 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>

 </androidx.cardview.widget.CardView>
