Android: Changing Background-Color of the Activity (Main View)

Question

I want to change the background color of my Main-View (not a Button or a Text-View) just the real background which is usually black... I got this code:

view.setBackgroundColor(0xfff00000); 

This is inside an OnClickListener, but it just changes the background of the Button.

Try creating a method in your Activity something like...

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

Then call it from your OnClickListener passing in whatever colour you want.
