Hello Tj Estrella Manzano RelativeLayout rel;

in button1.setOnClickListener write this rel=(RelativeLayout)findViewById(R.id.rel);

rel.setBackgroundColor(Color.BLUE);

This is the code to change the background color.

if you want to change the background image then you have to create a final Drawable

Drawable drawable = res.getDrawable(R.drawable.a); // a is the name of image stored in Drawable folder

and then rel.setBackground(drawable);
