How to have a tiled background

Today, I wanted to have a tiled background in my activity.
Until now, my android application only had a stretched image, so I though it was a good time for a change !

Having a background pattern that repeat itself seems like a very common idea, in particular on mobile development where you do not want to spend too much memory on a big image !



But actually it took much more time that I would have think to find this one !
I finally came up with this code :

public void onCreate(Bundle savedInstanceState)

{

super.onCreate(savedInstanceState);

setContentView(R.layout.main_menu);

View MainLayoutView = (View) findViewById(R.id.MainLayout);

BitmapDrawable MyTiledBG = new BitmapDrawable( BitmapFactory.decodeResource(getResources(), R.drawable.background) );

MyTiledBG.setTileModeXY( Shader.TileMode.REPEAT , Shader.TileMode.REPEAT );

MainLayoutView.setBackgroundDrawable( MyTiledBG );

<...>

}

(note that you can use also Shader.TileMode.MIRROR to have a different repeatition pattern )

This code works fine, but I would have prefered a XML way to do this.

I've seen the BitmapDrawable attribute defined in the SDK, but couldn't come with anything working...
