Android implements Flip flip animation

The example of this paper describes the Android to achieve the Flip flip animation effect method, to share for your reference.

The specific implementation code is as follows:

LinearLayout locationLL = (LinearLayout) findViewById(R.id.locationLL);
LinearLayout baseLL = (LinearLayout) findViewById(R.id.baseLL);

private void flipit() {
 Interpolator accelerator = new AccelerateInterpolator();
 Interpolator decelerator = new DecelerateInterpolator();
    final LinearLayout visibleList,invisibleList;
    final ObjectAnimator visToInvis, invisToVis;
    if (locationLL.getVisibility() == View.GONE) {
      visibleList = baseLL;
      invisibleList = locationLL;
      visToInvis = ObjectAnimator.ofFloat(visibleList, "rotationY", 0f, 90f);
      invisToVis = ObjectAnimator.ofFloat(invisibleList, "rotationY", -90f, 0f);
    } else {
      invisibleList = baseLL;
      visibleList = locationLL;
      visToInvis = ObjectAnimator.ofFloat(visibleList, "rotationY", 0f, -90f);
      invisToVis = ObjectAnimator.ofFloat(invisibleList, "rotationY", 90f, 0f);
    }
    visToInvis.setDuration(300);
    invisToVis.setDuration(300);
    visToInvis.setInterpolator(accelerator);
    invisToVis.setInterpolator(decelerator);
    visToInvis.addListener(new AnimatorListenerAdapter() {
      @Override
      public void onAnimationEnd(Animator anim) {
        visibleList.setVisibility(View.GONE);
        invisToVis.start();
        invisibleList.setVisibility(View.VISIBLE);
      }
    });
    visToInvis.start();
}

I hope the examples described in this article will be of some help to Android programming.
