ANDROID: Creating a button that needs to be pushed for X seconds

What I am looking for is to have a button where:

If you just push it, does nothing.

If you push and hold it for, let's say, 3 seconds, perform an action().

Any idea of what to do?

Thank you in advance.

If you want to be able to specify the time, here is an implementation of OnTouchListener that does that for you, without using a Timer:

class TimedTouchListener implements OnTouchListener{
    private final long millisRequired = 3000;
    private long downTime;

    @Override
    public boolean onTouch(View v, MotionEvent event){
        switch(event.getAction()){
        case MotionEvent.ACTION_DOWN:
            downTime = System.currentTimeMillis();
            return true;
            break;
        case MotionEvent.ACTION_UP:
            long upTime = System.currentTimeMillis();
            if( upTime - downTime > millisRequired ){
                doAction(); //doAction can be a method call, or any code you want to be executed.
                return true;
            }else{
                return true;
            }
        }
        return false;
    }
}

If you don't need to specify the time, just go with an OnLongClickListener as suggested by others.

Thats what the LongClickListener is for: http://developer.android.com/reference/android/view/View.OnLongClickListener.html

button.setOnTouchListener(new View.OnTouchListener() {

    @Override
    public boolean onTouch(View view, MotionEvent event) {
        // remeber here that ACTION_DOWN has occured
        // set the timer for 3 seconds
        // if ACTION_UP occured and timer has elapsed, then call action().
    }});

or as ntc noticed, you can use OnLongClickListener instead.
