Order of items in HashSet not correct

Question

As an exercise I am developing a simple notes application. Obviously the notes have to be saved persistently so I have the following method:

public static void s         


        

Answer 1

As requested, here is an example of serializing using a JSONArray.

Store the data:

SharedPreferences.Editor editor = sharedPreferences.edit();
editor.putString("jsonArray", new JSONArray(list).toString());
editor.commit();

Retreive the data:

try {
    JSONArray jsonArray = new JSONArray(sharedPreferences.getString(
            "jsonArray", null));
    // jsonArray contains the data, use jsonArray.getString(index) to
    // retreive the elements

} catch (JSONException e) {
    e.printStackTrace();
}
