如何在不传入上下文引用的情况下从类中的静态方法访问Android SharedPreferences？

public class MyApplication extends Application {
    private static SharedPreferences sharedPreferences;

    @Override
    public void onCreate() {
        super.onCreate();
        sharedPreferences = getSharedPreferences("my_prefs", Context.MODE_PRIVATE);
    }

    public static SharedPreferences getSharedPreferences() {
        return sharedPreferences;
    }
}

<application
    android:name=".MyApplication"
    ...
</application>

public class MyClass {
    public static void myStaticMethod() {
        SharedPreferences sharedPreferences = MyApplication.getSharedPreferences();
        // 使用SharedPreferences进行读写操作
    }
}
