    By default set the color of your parent layout and initialize it in Activity as:

    android:background="@color/green" or
layout.setBackgroundColor(Color.GREEN); onCreate of your activity

LinearLayout layout=(LinearLayout) findViewById(R.id.layout);

    Initialize 4 buttons in activity on their click write:

    layout.setBackgroundColor(Color.RED);
layout.setBackgroundColor(Color.BLUE);
layout.setBackgroundColor(Color.YELLOW);
layout.setBackgroundColor(Color.GREEN);

    where layout is your main layout of xml file

    set above color on particular buttons click events
