You can try this way:

runnable = new Runnable() {

        @Override
        public void run() {
            handler.postDelayed(runnable, 3000);
            imageSwitcher.setAutoStart(true);  
            imageSwitcher.startFlipping();
        }
    };

Change

imageSwitcher= (ViewFlipper) new ViewFlipper(this).findViewById(R.id.sportspersons);

To

imageSwitcher= (ViewFlipper) findViewById(R.id.sportspersons);
