Show multiple images in a imageView one after another with left to right flip effect repeatedly

Suppose I have multiple images in drawable folder(ex-8 images). I want to show all these images in a imageView one after another with left to right flip effect repeatedly(

ex-img[0],img[1],……img[8],img[0],img[1],…………
). How can I do this?

private void AnimateandSlideShow() {
image1 = (ImageView)findViewById(R.id.imageView1);
image1.setImageResource(img[currentimageindex1%img.length]);
currentimageindex1++;
Animation rotateimage = AnimationUtils.loadAnimation(this, R.anim.custom_anim);
image1.startAnimation(rotateimage);
}

Use custom function rotate image using handler for interval to change image,here i change image vice verse direction :

    private ImageView image1;
    private int[] imageArray;
    private int currentIndex;
    private int startIndex;
    private int endIndex;
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);

        image1 = (ImageView)findViewById(R.id.imageView1);
        imageArray = new int[8];
        imageArray[0] = R.drawable.one;
        imageArray[1] = R.drawable.two;
        imageArray[2] = R.drawable.three;
        imageArray[3] = R.drawable.four;
        imageArray[4] = R.drawable.five;
        imageArray[5] = R.drawable.six;
        imageArray[6] = R.drawable.seven;
        imageArray[7] = R.drawable.eight;

        startIndex = 0;
        endIndex = 7;
        nextImage();


    }

    public void nextImage(){
        image1.setImageResource(imageArray[currentIndex]);
        Animation rotateimage = AnimationUtils.loadAnimation(this, R.anim.custom_anim);
        image1.startAnimation(rotateimage);
        currentIndex++;
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                if(currentIndex>endIndex){
                    currentIndex--;
                    previousImage();
                }else{
                    nextImage();
                }

            }
        },1000); // here 1000(1 second) interval to change from current  to next image  

    }
    public void previousImage(){
        image1.setImageResource(imageArray[currentIndex]);
        Animation rotateimage = AnimationUtils.loadAnimation(this, R.anim.custom_anim);
        image1.startAnimation(rotateimage);
        currentIndex--;
        new Handler().postDelayed(new Runnable() {
            @Override
            public void run() {
                if(currentIndex<startIndex){
                    currentIndex++;
                    nextImage();
                }else{
                    previousImage(); // here 1000(1 second) interval to change from current  to previous image 
                }
            }
        },1000);

    }
