I GOT THE ANSWER...FOR MY QUESTION

ITS AUTOSLIDER

 public class AutoSlider extends Activity {

    public int currentimageindex=0;
    Timer timer;
    TimerTask task;
    ImageView slidingimage;

    int[] IMAGE_IDS = {R.drawable.image1, R.drawable.image2, R.drawable.image3,
            R.drawable.image4};

    @Override
    protected void onCreate(Bundle savedInstanceState) 
{
    // TODO Auto-generated method stub
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
        final Handler mHandler = new Handler();

        // Create runnable for posting
        final Runnable mUpdateResults = new Runnable() {
            public void run() {

                AnimateandSlideShow();

            }
        };

        int delay = 1000; // delay for 1 sec.

        int period = 8000; // repeat every 4 sec.

        Timer timer = new Timer();

        timer.scheduleAtFixedRate(new TimerTask() {

        public void run() {

             mHandler.post(mUpdateResults);

        }

        }, delay, period);

    }

    public void onClick(View v) {

        finish();
        android.os.Process.killProcess(android.os.Process.myPid());
      }
       private void AnimateandSlideShow() {

        slidingimage = (ImageView)findViewById(R.id.ImageView_id);
        slidingimage.setImageResource(IMAGE_IDS[currentimageindex%IMAGE_IDS.length]);

        currentimageindex++;

      }

}

and in your XML have just the layout and the image view with its width,height and position.

You can use the View Pager along with the Timer: On each time tick change the page of the view pager using pager adapter:

Official defination of View pager:

Layout manager that allows the user to flip left and right through pages of data. You supply an implementation of a PagerAdapter to generate the pages that the view shows

Please look at some examples of View pager and view flippers :
