android button setPressed after onClick

Question

yesterday I noticed the possibility to integrate Fragments in older API Levels through the Compatibility package, but thats not really essential for the question. :)

I have a Button with an OnClickListener

Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(new OnClickListener() {
    @Override
    public void onClick(View v) {
        doSomething();
        button.setPressed(true);
    }
});

Because of the actual clicking, it is shown as pressed and after releasing the click, the button state is not pressed and stays that way.

Is there a simple way that keeps the button state pressed after releasing? First thing I can think of would be some sort of timer, but that seems unreasonable.

Just to note this is because Android is changing the setPressed both before and after your onClickEvent, so changing it yourself has no effect. Another way to get around this is to use the onTouchEvent.

button.setOnTouchListener(new OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        // show interest in events resulting from ACTION_DOWN
        if (event.getAction() == MotionEvent.ACTION_DOWN) return true;

        // don't handle event unless its ACTION_UP so "doSomething()" only runs once.
        if (event.getAction() != MotionEvent.ACTION_UP) return false;

        doSomething();
        button.setPressed(true);                    
        return true;
   }
});
