Android:更改 WindowManager 添加的 View 的 LayoutParams [英] Android: change LayoutParams of View added by WindowManager

问题描述

我有由 WindowManager 管理的叠加 View，就像在 this问题.

I have overlay View managed by WindowManager, just like in this question.

简而言之，它看起来像这样:

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);

它有效，但如果我需要更改布局参数，我需要删除 View 并再次添加它，如下所示:

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);

看起来不是很漂亮.我试图做 my_view.setLayoutParams(my_view_layout_params)，但不幸的是它不起作用.我该怎么做?

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?

推荐答案

WindowManager 有一个 updateViewLayout() 成员...确定这正是您想要的吗?

WindowManager has an updateViewLayout() member... surely that's exactly what you want?

windowManager.updateViewLayout(my_view, my_view_layout_params);
