从ServiceAdapter中获取数据

Question

我有一个使用ViewHolders的BaseAdapter类来显示已检查的应用列表。我使用SharedPreferences存储选中的应用程序，以便检查已检查的应用程序。我想要实现的是将我的服务类中的已检查应用程序理想地存储在arraylist或类似的东西中。

问题是密钥是我以前用来获取值在BaseAdapter类中的，我无法从服务类中获取它所以我不得不重新创建获取包列表和迭代的方法通过for循环。

我也无法检查我的Service类中是否已选中holder复选框，因为这是在我的BaseAdapter类中完成的。

尽管在BaseAdapter中传递了上下文并将getApplicationContext与SharedPreferences一起使用，但我无法获得服务类中已检查应用的列表。我不知道现在在哪里转。我已经尝试过使用静态变量，尝试从BaseAdapter类获取上下文等所有内容。

这是我的适配器类（我已经评论了我在哪里获得了被检查的应用程序）：

最终，我可以尝试完成工作，以便在我的服务类中获取已检查应用的列表。所以，无论什么时候我运行服务，我都有已检查的应用程序列表。每当应用程序打开时，重新打开，重新启动或执行任何操作等等。

帮助表示赞赏。如果还有什么我可以补充的，请告诉我。

我最终在SharedPreferences中创建了一个新数据库，仅存储已检查的应用程序。
