如何从退出中删除闪烁显示动画并使其从触摸点显示

Question

我想要实现的目标是：

1. 当单击recyclerView中的某个项目时，详细信息活动应显示，从我的手指接触到的点开始 屏幕。

2. 当我触摸向上箭头按钮或后退按钮时，细节活动应以圆形显示结束并停在 我的手指最初触摸了屏幕。

我的代码：

MyRecyclerViewHolder

private OnGridItemClickedListener itemClickedListener

    public MyRecyclerViewHolder(View itemView,  OnGridItemClickedListener itemClickedListener) {
        super(itemView);
        ButterKnife.bind(this, itemView);
        this.itemClickedListener = itemClickedListener;
        rippleView.setOnTouchListener(touchListener);
    }


    private View.OnTouchListener touchListener = new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            if (event.getAction() == MotionEvent.ACTION_UP) {
                itemClickedListener.onItemClick(getAdapterPosition(), null, (int)event.getY(), (int)event.getX());
            }
            return true;
        }
    };

MyFragment

// Removed irrelevant codes
 MyAdapter adapter = new MyAdapter(itemsList, true);
 recyclerView.setLayoutManager(new GridAutoFitLayoutManager(getActivity(), MyConvert.dpToPx(150, getActivity())));
 recyclerView.setAdapter(adapter);
 recyclerView.setHasFixedSize(true);

 adapter.setOnGridItemClickedListener(new OnGridItemClickedListener() {
     @Override
     public void onItemClick(int position, String stringId, int y, int x) {
         launchMyDetailsActivity(position, y, x);
     }
 });

 private void launchMyDetailsActivity(int index, int y, int x) {
     Intent intent = new Intent(getActivity(), MyDetailsActivity.class);
     intent.putExtra(Keys.EXTRA_Y, y);
     intent.putExtra(Keys.EXTRA_X, x);
     startActivity(intent);
 }

MyDetailsActivity

// Removed irrelevant codes

 @Override
 protected void onCreate(Bundle savedInstanceState) {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.activity_grid_details);
     ButterKnife.bind(this);
     setSupportActionBar(toolbar);
     getSupportActionBar().setDisplayHomeAsUpEnabled(true);
     setViewListeners();
     startEnterTransition();
 }

 private void startEnterTransition () {
     coordinatorLayout.post(new Runnable() {
         @Override
         public void run() {
             int x = getIntent().getIntExtra(Keys.EXTRA_X, 0);
             int y = getIntent().getIntExtra(Keys.EXTRA_Y, 0);

             if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP && x != 0 && y != 0) {
                 // get the final radius for the clipping circle
                 int finalRadius = Math.max(coordinatorLayout.getWidth(), coordinatorLayout.getHeight()) / 2;

                 // create the animator for this view (the start radius is zero)
                 Animator anim = ViewAnimationUtils.createCircularReveal(coordinatorLayout, x, y, 0, finalRadius);

                 // make the view visible and start the animation
                 coordinatorLayout.setVisibility(View.VISIBLE);
                 anim.start();
             }
         }
     });
 }

 private void startExitTransition () {
     int x = getIntent().getIntExtra(Keys.EXTRA_X, 0);
     int y = getIntent().getIntExtra(Keys.EXTRA_Y, 0);

     if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP && x != 0 && y != 0) {
         int initialRadius = coordinatorLayout.getWidth() / 2;

         Animator anim = ViewAnimationUtils.createCircularReveal(coordinatorLayout, x, y, initialRadius, 0);

         anim.addListener(new AnimatorListenerAdapter() {
             @Override
             public void onAnimationEnd(Animator animation) {
                 super.onAnimationEnd(animation);
                 coordinatorLayout.setVisibility(View.INVISIBLE);
                 supportFinishAfterTransition();
             }
         });

         anim.start();

     } else {
         supportFinishAfterTransition();
     }
 }

 @Override
 public void onBackPressed() {
     startExitTransition();
 }

 @Override
 public boolean onOptionsItemSelected(MenuItem item) {
     switch (item.getItemId()) {

         case android.R.id.home:
             startExitTransition();
             return true;
     }

     return super.onOptionsItemSelected(item);
 }

问题

1. 揭幕动画从屏幕的左上角开始，即使我点击的项目接近底部，也靠近汉堡图标 的屏幕。退出动画也是如此，它停在屏幕的左上角

2. 退出动画结束后，屏幕闪烁，并不会一直发生，但确实会发生。

已实施解决方案

我在viewHolder中尝试了这个：itemView.getX()和itemView.getY()，itemView.getRight()和itemView.getTop()。这些出现了    要解决上面的第一个问题，但动画的进入和退出点总是从recyclerView项目的位置开始。

请问如何解决上面的数字和2个问题？
