Answer 1

You can use this piece of code to run after a 3 sec delay.

new Timer().schedule(new TimerTask() {          
    @Override
    public void run() {

        // run your code here    

    }
}, 3000);

Answer 2

Make a sign of boolean in your postdelayed method. Init the sign as true,when the activity is finnished , set the value of sign as false.

Answer 3

You can use removeCallbacks(runnable) method of the handler using which you are calling postDelayed() method. For example, if you used:

mHandler.postDelayed(mRunnable, mTime)

for refreshing the activity, then use

mHandler.removeCallbacks(mRunnable)

in onPause() method of the activity.
