从服务访问共享首选项 [英] Access shared preference from a service

问题描述

我对android很陌生.

I am fairly new to android.

我的应用程序中有活动.我使用共享首选项来存储与该活动有关的一些数据.现在，如何从另一个服务类访问那些存储的数据?是否有可能?

I have an activity in my application. I used shared preferences to store some data related to that activity. Now, how can I access those stored data from another service class? Is it possible?

非常感谢您的关注.

推荐答案

看到您已经在扩展Context的应用程序组件中，则可以简单地使用:

Seeing as you're already in an application component that extends Context, you can simply use:

SharedPreferences prefs = this.getSharedPreferences("Pref name", Context.MODE_PRIVATE);

确保在onCreate()或之后调用此电话.

Make sure you call this in or after onCreate().
