but the image will not stay on after I released the button. I want to click the button and the button change to a new image. Can this be done?

Answer 1

in onClick method you need to change the Button's image, this way..

public void onClick(View v) {
    if(v==buttonName){
        buttonName.setBackgroundResource(R.drawable.imageName);
    }       
}
