Button only clickable after X seconds

Question

I am trying to create a button which is only clickable after for example 3 seconds. It should display a countdown, when 0 is reached, one can click the button and an action gets performed. For example when the Activity gets called, the button displays a "3" first and counts down to "0", only then one can click on the button.

Any ideas how to achieve this?

Answer 1

you should use CountDownTimer for that:

timer = new CountDownTimer( 3000, 1000 ) {
  @Override public void onTick( long millisUntilFinished ) {
    button.setText( "count down " + millisUntilFinished );
  }
  @Override public void onFinish() { 
    button.setOnClickListener( onClickListener );
  }
};

somewhere down below:

timer.start()
