How to allow user to set background of a custom android launcher

Question

I wanted to provided users with an option to set the background my custom launcher. However, the code I tried only set the background of the default home screen and not of my launcher. Can I make the code to change the background of my custom launcher.

Answer 1

What do you mean by launcher? You can just put some buttons up and have each one do something along the lines of this

public void setActivityBackgroundColor(int color) {
        View view = this.getWindow().getDecorView();
        view.setBackgroundColor(color);
    }

and obviously change the color to the ones you want them to be able to select.
