No need to do any custom thing.As Android provides the facility like this in ViewFlipper class.It is actually made for it.

View Flipper:-

Simple ViewAnimator that will animate between two or more views that have been added to it. Only one child is shown at a time. If requested, can automatically flip between each child at a regular interval.

Its very nice and also built in support for animation so just use this for this purpose. To implement the ViewFlipper in your application I am sharing some good tutorials..

    You can also get more info at here. http://developer.android.com/reference/android/widget/ViewFlipper.html.

    Enjoy..!

    View Pager refer this is one option, otherwise you can add a simple gesture listener to your image view.

    //Adding gesture listener to image view.

    final GestureDetector gdt = new GestureDetector(new GestureListener());
        final ImageView imageView  = (ImageView) findViewById(R.id.image_view);
        imageView.setOnTouchListener(new OnTouchListener() {
            @Override
            public boolean onTouch(final View view, final MotionEvent event) {
                gdt.onTouchEvent(event);
                return true;
            }
        });

    //The gesture listener class

      private class GestureListener extends SimpleOnGestureListener {
            @Override
            public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX, float velocityY) {
                if(e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
//load previous image here
                    return false; // Right to left
                }  else if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY) {
//load next image here
                    return false; // Left to right
                }

                if(e1.getY() - e2.getY() > SWIPE_MIN_DISTANCE && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {
                    return false; // Bottom to top
                }  else if (e2.getY() - e1.getY() > SWIPE_MIN_DISTANCE && Math.abs(velocityY) > SWIPE_THRESHOLD_VELOCITY) {
                    return false; // Top to bottom
                }
                return false;
            }
        }
