推荐答案

迟到不止一次=)这是我的决定，允许您将PopupMenu设置为指定的坐标.代码不是很好，但是可以.

Better late than once =) This is my decision, allows you to set PopupMenu to the specified coordinates. The code is not very good but it works.

public void show(Activity activity, float x, float y)
{
    final ViewGroup root = (ViewGroup) activity.getWindow().getDecorView().findViewById(android.R.id.content);

    final View view = new View(context);
    view.setLayoutParams(new ViewGroup.LayoutParams(1, 1));
    view.setBackgroundColor(Color.TRANSPARENT);

    root.addView(view);

    view.setX(x);
    view.setY(y);

    PopupMenu popupMenu = new PopupMenu(context, view, Gravity.CENTER);

    popupMenu.setOnDismissListener(new PopupMenu.OnDismissListener()
    {
        @Override
        public void onDismiss(PopupMenu menu)
        {
            root.removeView(view);
        }
    });

    popupMenu.show();
}
