Create a RelativeLayout
with a background of the yellow color and add the circle image on top.
This is a far more dynamic solution than using a single image as the RelativeLayout
will change size depending on screen size/orientation and not affect the sizing of the circle
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="#ffc20e">
<ImageView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:background="@drawable/circle_image" />
</RelativeLayout>
