这个动画自己粘 这里写反 很酸爽

控制上下左右弹出
右
popupWindow.showAsDropDown(view, view.getWidth(), -view.getHeight());
左
popupWindow.showAsDropDown(view, -popupWindow.getWidth(), -view.getHeight());
全屏
popupWindow.showAtLocation(findViewById(android.R.id.content), Gravity.BOTTOM, 0, 0);
上
popupWindow.showAsDropDown(view, 0, -(popupWindow.getHeight() + view.getMeasuredHeight()));
