You can try this as simple

// when you click this demo image

image.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
    image.setImageResource(R.drawable.secondimage);
    //add some codes

try this:

image.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {
        switch(event.getAction()){
        case MotionEvent.ACTION_DOWN:
            image.setImageResource(R.drawable.b);
            break;
        case MotionEvent.ACTION_UP:
            image.setImageResource(R.drawable.a);
            break;
        }
        return true;
    }
});
