[android] Overlapping Views in Android

Is it possible to have overlapping views in Android? I would like to have an ImageView with a transparent png in the front and another view in the background.

edit:

This is what I have at the moment, the problem is that the image in the imageView is not transparent, the parts that should be transparent are just black.

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:id="@+id/gallerylayout"
>
<Gallery android:id="@+id/overview"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    />

 <ImageView android:id="@+id/navigmaske"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:src="@drawable/navigmask"
    /> 

</RelativeLayout>

edit:

I got it to work, it was a theme file from another programmer on the team. Just changed this

<item name="android:background">#FF000000</item>

to this

<item name="android:background">#00000000</item>

The simples way arround is to put -40dp margin at the buttom of the top imageview

Visible gallery changes visibility which is how you get the gallery over other view overlap. the Home sample app has some good examples of this technique.

Also, take a look at FrameLayout, that's how the Camera's Gallery application implements the Zoom buttons overlay.

Yes, that is possible. The challenge, however, is to do their layout properly. The easiest way to do it would be to have an AbsoluteLayout and then put the two images where you want them to be. You don't need to do anything special for the transparent png except having it added later to the layout.

If you want to add you custom Overlay screen on Layout, you can create a Custom Linear Layout and get control of drawing and key events. You can my tutorial- Overlay on Android Layout- http://prasanta-paul.blogspot.com/2010/08/overlay-on-android-layout.html
