如何在单例中避免Android上下文中的静态字段？

public class MySingleton {
    private static WeakReference<Context> contextRef;

    public static void setContext(Context context) {
        contextRef = new WeakReference<>(context);
    }

    public static Context getContext() {
        if (contextRef != null) {
            return contextRef.get();
        }
        return null;
    }
}

public class MySingleton {
    private Context context;

    private static MySingleton instance;

    private MySingleton(Context context) {
        this.context = context;
    }

    public static synchronized MySingleton getInstance(Context context) {
        if (instance == null) {
            instance = new MySingleton(context);
        }
        return instance;
    }

    // 其他方法...
}
