问题描述

有没有办法在静态方法中获取当前的Context实例?

Is there a way to get the current Context instance inside a static method?

我正在寻找这种方式,因为我讨厌每次更改上下文"实例时都会保存.

I'm looking for that way because I hate saving the 'Context' instance each time it changes.

推荐答案

执行以下操作:

在Android Manifest文件中,声明以下内容.

In the Android Manifest file, declare the following.

<application android:name="com.xyz.MyApplication">

</application>

然后编写课程:

public class MyApplication extends Application {

    private static Context context;

    public void onCreate() {
        super.onCreate();
        MyApplication.context = getApplicationContext();
    }

    public static Context getAppContext() {
        return MyApplication.context;
    }
}

现在到处都调用MyApplication.getAppContext()以静态获取您的应用程序上下文.

Now everywhere call MyApplication.getAppContext() to get your application context statically.
