推荐答案

假设preference的WORLD_READABLE，这可能工作：

Assuming the preference are WORLD_READABLE, this might work:

final ArrayList<HashMap<String,String>> LIST = new ArrayList<HashMap<String,String>>();
Context myContext = createPackageContext("com.example", 
Context.MODE_WORLD_WRITEABLE); // where com.example is the owning  app containing the preferences
  SharedPreferences testPrefs = myContext.getSharedPreferences 
("test_prefs", Context.MODE_WORLD_READABLE); 


Map<String, ?> items = testPrefs .getAll();
for(String s : items.keySet()){
    //do somthing like String value=  items.get(s).toString());
    }
