swipe animation in layouts: android

I know the animation effects and how to apply them to views(layouts) for onclicklistener, ontouchlistener etc. but which event occurs when i slide the layout to left or right.

previousButton.setOnClickListener(new OnClickListener()  {
      @Override 
        publicvoid onClick(View v) {  
              viewFlipper.setInAnimation(MainActivity.this,R.anim.view_transition_in_right);
               viewFlipper.setOutAnimation(MainActivity.this,R.anim.view_transition_out_right);
               viewFlipper.showPrevious();  
      }  
    });  
}

i dont want onclicklistener. ie)if i touch and slide the current layout to left, it should go out and next layout should be in current view.how to do this?

Make your activity implement the onGestureListener.

then in you activity add 

private GestureDetector gestureScanner;
gestureScanner = new GestureDetector(this);
private static final int SWIPE_MIN_DISTANCE = 100;
    private static final int SWIPE_THRESHOLD_VELOCITY = 100;

Then overrid the onTouchEvent(MotionEvent event) like below:

@Override
    public boolean onTouchEvent(MotionEvent event) {
        return gestureScanner.onTouchEvent(event);
    }

Also Finally you need to overide onFling method something like:

@Override
    public boolean onFling(MotionEvent e1, MotionEvent e2, float velocityX,
            float velocityY) {
        /* on scroll to the next page */
        if (e2.getX() - e1.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY
                ) {
            //Ur code goes here
        }
        /* on scroll to the previous page  */
        else if (e1.getX() - e2.getX() > SWIPE_MIN_DISTANCE
                && Math.abs(velocityX) > SWIPE_THRESHOLD_VELOCITY
                ) {
            //ur code goes here.
        }
        return false;
    }

Hope this helps.

You need the View pager -

ViewPager

Very easy to implement too, you just provide an adapter in a similar way that you would with a ListView.

You should use Fragments for sliding between views. Use FragmentActivity and Fragment(for each view).android developers example

Or you can just use this opensource library
