PopupMenu显示时滚动工具栏

Question

我正在使用包含Toolbar和TabLayout的AppbarLayout的CoordinatorLayout,并包含ViewPager,显示包含CardView的RecyclerView的3个片段.

问题是当单击CardView上的ImageView(3个点)PopupMenu显示但工具栏向上滚动.

这是带工具栏的设计

单击然后工具栏上的问题消失

这是我的容器活动xml

更换

PopupMenu popupMenu = new PopupMenu(MainActivity.this,view);

至

PopupMenu popupMenu = new PopupMenu(MainActivity.this,view, Gravity.RIGHT);

会帮助你.
