How to make imageview over another view in Android ?

There are at least 3 ways to put imageview on another imageview. Simple Order This way is just put the imageview after the other imageview in XML file. It is simple like that. The first view will be underneath the second one. Using FrameLayout <FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="wrap_content" android:layout_height="wrap_content" > <ImageView android:id="@+id/imageView2" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/t" /> <ImageView android:id="@+id/imageView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:src="@drawable/ic_launcher" /> </FrameLayout> The second image will be on top. Put imageview on another imageview exactly <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/white" > <ImageView android:id="@+id/inside_imageview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_marginBottom="5dip" android:layout_marginTop="5dip" android:src="@drawable/frame" /> <ImageView android:id="@+id/outside_imageview" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignTop="@id/inside_imageview" android:layout_alignBottom="@id/inside_imageview" android:layout_alignLeft="@id/inside_imageview" android:layout_alignRight="@id/inside_imageview" android:scaleType="fitXY" /> </RelativeLayout> As you can see, the second imageview has those properties.
