How to highlight images in android (automatically)?

I have an answer ... for my question

HIS 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 there is only a layout and image with its width, height and position.
