  <p>This is my implementation in xml:</p>
  
  <pre><code>&lt;android.support.design.widget.FloatingActionButton
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:layout_marginBottom="16dp"
      android:layout_alignParentBottom="true"
      android:layout_centerHorizontal="true"
      android:src="@drawable/white_plus"
      android:id="@+id/plusIcon"
      android:padding="0dp"
      app:pressedTranslationZ="12dp"
      app:elevation="6dp"
      app:paddingEnd="0dp"
      app:paddingStart="0dp"
      android:clickable="true"/&gt;
  </code></pre>
