Answer 1

For delayed actions in Android I'd recommend using the Android Handler class with its postDelayed() method.

Create a handler for your Activity as a member variable:

private Handler mHandler = new Handler(); 

And then add your delay action as follows:

mHandler.postDelayed(new Runnable() { 
        public void run() { 
            //Do you thing here
        } 
    },2000);
