Answer 1

Make it in code perhaps. Put a listener on the button and when the button is clicked the background is changed.

Answer 2

You can do it easily within the code.

boolean isPressed = false;
button.setOnClickListener(buttonListener);

OnClickListener buttonListener = new OnClickListener() {
    @Override
    public void onClick(View v) {
        if(isPressed)
           button.setBackgroundResource(R.drawable.icon1);
        else
           button.setBackgroundResource(R.drawable.icon2);

        isPressed = !isPressed;
   }
};

Simple way

btn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
    btn.setBackgroundDrawable(getResources().getDrawable(R.drawable.locationbutton_on));
                }
        });
