Android：更改WindowManager添加的View的LayoutParams
我有由 WindowManager 管理的覆盖 View，就像这个问题。
简而言之，它看起来像这样：
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
my_view_layout_params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
wm.addView(my_view, my_view_layout_params);
它可以工作，但是如果我需要更改布局参数，我需要删除 View 并再次添加它，就像这样：
wm.removeView(my_view);
wm.addView(my_view, my_view_layout_params);
它看起来不是很漂亮。我尝试执行 my_view.setLayoutParams(my_view_layout_params) ，但不幸的是它不起作用。我该怎么做？
I have overlay View managed by WindowManager, just like in this question.
Briefly, it looks like this:
WindowManager wm = (WindowManager) getSystemService(WINDOW_SERVICE);
my_view_layout_params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.TYPE_SYSTEM_OVERLAY,
WindowManager.LayoutParams.FLAG_WATCH_OUTSIDE_TOUCH,
PixelFormat.TRANSLUCENT);
wm.addView(my_view, my_view_layout_params);
It works, but if i need to change layout params, i need to remove View and add it again, like that:
wm.removeView(my_view);
wm.addView(my_view, my_view_layout_params);
It looks not very beautiful. I tried to do my_view.setLayoutParams(my_view_layout_params), but it does not work unfortunately. How can i do it?

你可以使用这个：
You can use this:
WindowManager 有一个
updateViewLayout()成员...这肯定正是您想要的吗？WindowManager has an
updateViewLayout()member... surely that's exactly what you want?
