Get screen width and height in a Fragment
提问by pengwang
If I extend activity in my app I can get width and height:
如果我在我的应用程序中扩展活动，我可以获得宽度和高度：
DisplayMetrics displaymetrics = new DisplayMetrics();
getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int wwidth = displaymetrics.widthPixels;
or
或者
Display display = getWindowManager().getDefaultDisplay();
stageWidth = display.getWidth();
stageHeight = display.getHeigth();
But at present I extend fragment and I can't use the above code to get the width.
但是目前我扩展了片段并且我不能使用上面的代码来获取宽度。

Try below modifed code of yours
尝试以下修改后的代码
DisplayMetrics displaymetrics = new DisplayMetrics();
getActivity().getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
int height = displaymetrics.heightPixels;
int width = displaymetrics.widthPixels;
or
或者
Display display = getActivity().getWindowManager().getDefaultDisplay();
stageWidth = display.getWidth();
stageHeight = display.getHeigth();
Basically you just required to put getActivity()(to get the context) before getWindowManager()function.
基本上你只需要getActivity()在getWindowManager()函数之前放置（获取上下文）。

This will give you what you want without needing for context or view:
这将为您提供所需的内容，而无需上下文或视图：
import android.content.res.Resources;
int width = Resources.getSystem().getDisplayMetrics().widthPixels;
int height = Resources.getSystem().getDisplayMetrics().heightPixels;

This code also works with Fragments:
此代码也适用于片段：
int width = getResources().getConfiguration().screenWidthDp;
int height = getResources().getConfiguration().screenHeightDp;
For comparing orientation:
用于比较方向：
if(getResources().getConfiguration().orientation == Configuration.ORIENTATION_LANDSCAPE){...}
