推荐答案

您可以使用gson.jar存储类对象为共享preferences。 您可以立即下载这个罐子从这里https://$c$c.google.com/p/google-gson/downloads/list

You can use gson.jar to store class objects into SharedPreferences. You can downlaod this jar from here https://code.google.com/p/google-gson/downloads/list

//Creating a shared preference
SharedPreferences  mPrefs = getPreferences(MODE_PRIVATE);

要保存

     Editor prefsEditor = mPrefs.edit();
     Gson gson = new Gson();
     String json = gson.toJson(MyObject);
     prefsEditor.putString("MyObject", json);
     prefsEditor.commit();

中检索

    Gson gson = new Gson();
    String json = mPrefs.getString("MyObject", "");
    MyObject obj = gson.fromJson(json, MyObject.class);
