安卓：获取屏幕分辨率/像素的整数值 [英] Android: Get the screen resolution / pixels as integer values

问题描述

这是一个上，我发现没有答案很简单的问题：/ 我怎样才能快速进入屏幕分辨率（宽，高）作为整数值？

this is a really simple question on which I've found no answer :/ How can I quickly access the screen resolution (width, height) as integer values?

我已经试过这一个，但它总是在我的模拟器显示零：

I've tried this one, but it always shows zero on my emulator:

DisplayMetrics dm = new DisplayMetrics();
int width = dm.widthPixels / 2;

在我来说，我想动态创建一个表tableRows，每块包含两个COLS。这COLS都应当填写半个屏幕的宽度。

In my case I want to dynamically create a table with tableRows, each containing two cols. This cols all shall fill half of the screen in width.

有人可以给我一个提示？

Can someone give me a hint?

推荐答案

最简单的方法将是实施<一个href="http://developer.android.com/reference/android/view/View.html#onSizeChanged%28int,%20int,%20int,%20int%29"相对=nofollow> onSizeChanged 。你可能会得到一个0值，因为该观点尚未初始化。你不能拨打以上code在例如查看构造。

The easiest way will be to implement onSizeChanged. You are probably getting a value of 0 because the view hasn't initialized yet. You can't call the above code in the View constructor for example.
