Monodroid 屏幕尺寸 [英] Monodroid screen dimensions

问题描述

我正在尝试引用 WindowManger 以便我可以获得默认屏幕的尺寸，但我似乎找不到对它的引用.(这是 API 8，froyo 2.2).我什至尝试过:

I'm trying to reference WindowManger so I can get the default screen's dimensions but I can't seem to find reference to it. (this is API 8, froyo 2.2). I even tried:

dynamic wm = Android.App.Application.Context.GetSystemService(Android.Content.Context.WindowService);
Display display = wm.getDefaultDisplay();

但是得到一个错误，指出 Object 没有响应 getDefaultDisplay.

But got an error indicating that Object doesn't respond to getDefaultDisplay.

我也试过:

var wm = (IWindowManager)Android.App.Application.Context.GetSystemService(Android.Content.Context.WindowService);
Display display = wm.DefaultDisplay;

但我收到了无效的强制转换异常.

But I get an invalid cast exception.

看到这篇文章，但我无法解决<代码>窗口管理器.知道这里发生了什么吗?

Saw this post, but I can't resolve WindowManager. Any ideas what's going on here?

推荐答案

WindowManager 是 IWindowManager 接口.尝试使用 .JavaCast<T 而不是演员表>() 扩展方法:

WindowManager is the IWindowManager interface. Instead of the cast, try using the .JavaCast<T>() extension method:

var wm = context.GetSystemService(Android.Content.Context.WindowService)
    .JavaCast<IWindowManager>();
var d  = wm.DefaultDisplay;
