You can use Handler with recursion

boolean firstOpen = false;
public void animateDrawer(){
    new Handler().postDelayed(new Runnable() {
                        @Override
                        public void run() {
                         if(!firstOpen)
                           {
                             // open your Drawer here
                             firstOpen = true;
                             animateDrawer();
                           }
                           else
                           {
                             // close your Drawer here
                           }
                        }
                    },1000);
//1000 is a 1 second delay
}

How can i close it, after 1 sec – Jaison_Joseph Sep 28 '16 at 08:21
It is working on a boolean condition on first 1 sec it will call itself, and after 2 sec it will not call itself so after closing the drawer it will end itself. – Nitesh Sep 28 '16 at 08:23

You can either use CountDown Timer,

new CountDownTimer(30000, 1000) {

    public void onTick(long millisUntilFinished) {
        mTextField.setText("seconds remaining: " + millisUntilFinished / 1000);
       //here you can have your logic to set text to edittext
    }

    public void onFinish() {
        mTextField.setText("done!");
    }

}.start();

Or Post Delayed,

final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
      @Override
      public void run() {
        //Do something after 100ms
        Toast.makeText(c, "check", Toast.LENGTH_SHORT).show();  
        handler.postDelayed(this, 2000);
      }
    }, 1500);

You can use Handler to achieve wait time in your code

Handler handler = new Handler();
            handler.postDelayed(new Runnable() {
                public void run() {
                    // Actions to do after 1 second
                }
            }, 1000);
