<pre><code>&lt;RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent" &gt;

&lt;RelativeLayout
    android:id="@+id/layoutTop"
    android:layout_width="match_parent"
    android:layout_height="200dp"
    android:background="#355482" &gt;
&lt;/RelativeLayout&gt;

&lt;RelativeLayout
    android:id="@+id/layoutBottom"
    android:layout_width="match_parent"
    android:layout_height="0dp"
    android:layout_alignParentBottom="true"
    android:layout_below="@+id/layoutTop"
    android:background="@drawable/loading" &gt;

    &lt;TextView
        android:id="@+id/textView1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="113dp"
        android:text="Profile"
        android:textColor="#355482"
        android:textSize="20dp"
        android:textStyle="bold" /&gt;
&lt;/RelativeLayout&gt;

&lt;ImageView
    android:id="@+id/overlapImage"
    android:layout_width="150dp"
    android:layout_height="150dp"
    android:layout_alignParentTop="true"
    android:layout_centerHorizontal="true"

    android:adjustViewBounds="true"
    android:background="@drawable/round_image"
    android:src="@drawable/ic_launcher" /&gt;
</code></pre>

<p>
this is round_image.xml:</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;

&lt;shape xmlns:android="http://schemas.android.com/apk/res/android" 
android:shape="oval"&gt;

&lt;solid android:color="#ffffff" /&gt;
&lt;corners android:radius="2dp"/&gt;

&lt;size
    android:height="80dp"
    android:width="80dp" /&gt;

&lt;padding
    android:bottom="0dp"
    android:left="0dp"
    android:right="0dp"
    android:top="0dp" /&gt;

&lt;/shape&gt;
</code></pre>
