Dynamically setting bg image with viewgroup.layoutparams

Question

I have a grid view that I reuse a few times in an app. Separate activities drive what data appears. I would like to set different bg images for each activity.

What I would like to do is avoid creating multiple layouts by using viewgroup.layoutparams.

Currently, I have this:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.grid_view);

But I would like to have something like this:

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.grid_view, ViewGroup.LayoutParams.View_background(R.drawable.background1));

Only one issue: there is no View_background layout parm...

This is an RTM but I can't seem to find it. Anyone know what it is? Is there one?

You can not change background using LayoutParams. Instead, assign an ID to the root view in your XML file and use this code to change the background:
findViewById(R.id.your_view).setBackgroundResource(R.drawable.background1);
