使用这个对象——> TinyDB——Android-Shared-Preferences-Turbo非常简单。

TinyDB tinydb = new TinyDB(context);

把

tinydb.putList("MyUsers", mUsersArray);

得到

tinydb.getList("MyUsers");

更新

一些有用的例子和故障排除可以在这里找到:Android共享偏好TinyDB putListObject函数

从SharedPreference中保存和检索ArrayList

 public static void addToPreference(String id,Context context) {
        SharedPreferences sharedPreferences = context.getSharedPreferences(Constants.MyPreference, Context.MODE_PRIVATE);
        ArrayList<String> list = getListFromPreference(context);
        if (!list.contains(id)) {
            list.add(id);
            SharedPreferences.Editor edit = sharedPreferences.edit();
            Set<String> set = new HashSet<>();
            set.addAll(list);
            edit.putStringSet(Constant.LIST, set);
            edit.commit();

        }
    }
    public static ArrayList<String> getListFromPreference(Context context) {
        SharedPreferences sharedPreferences = context.getSharedPreferences(Constants.MyPreference, Context.MODE_PRIVATE);
        Set<String> set = sharedPreferences.getStringSet(Constant.LIST, null);
        ArrayList<String> list = new ArrayList<>();
        if (set != null) {
            list = new ArrayList<>(set);
        }
        return list;
    }

我使用相同的方式保存和检索字符串，但这里我使用HashSet作为数组列表的中介

使用HashSet保存arrayList到SharedPreferences:

1-我们创建SharedPreferences变量(在数组发生变化的地方)

2 -我们将数组列表转换为HashSet

3 -然后放入stringSet并应用

4 -你在HashSet中获取stringset并重新创建ArrayList来设置HashSet。

public class MainActivity extends AppCompatActivity {
    ArrayList<String> arrayList = new ArrayList<>();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SharedPreferences prefs = this.getSharedPreferences("com.example.nec.myapplication", Context.MODE_PRIVATE);

        HashSet<String> set = new HashSet(arrayList);
        prefs.edit().putStringSet("names", set).apply();


        set = (HashSet<String>) prefs.getStringSet("names", null);
        arrayList = new ArrayList(set);

        Log.i("array list", arrayList.toString());
    }
}

public static void WriteSharePrefrence1(Context context, String key, 
ArrayList<HashMap<String, String>> value)
{
    final SharedPreferences preferences = 
    PreferenceManager.getDefaultSharedPreferences(context);
    SharedPreferences.Editor editor = preferences.edit();
    Gson gson = new Gson();
    String json = gson.toJson(value);
    editor.putString(key, json);
    editor.commit();
}
public static ArrayList<HashMap<String, String>> ReadSharePrefrence1(Context context, 
 String key)
{
    String data;
    Gson gson = new Gson();
    ArrayList<HashMap<String, String>> items = new ArrayList<>();
    final SharedPreferences preferences = 
    PreferenceManager.getDefaultSharedPreferences(context);
    final SharedPreferences.Editor editor = preferences.edit();
    data = preferences.getString(key, "");

    Type type = new TypeToken<ArrayList<HashMap<String, String>>>() {}.getType();
    items = gson.fromJson(data, type);

    return items;
}

别忘了实现Serializable:

Class dataBean implements Serializable{
 public String name;
}
ArrayList<dataBean> dataBeanArrayList = new ArrayList();

该方法用于存储/保存数组列表:-

 public static void saveSharedPreferencesLogList(Context context, List<String> collageList) {
            SharedPreferences mPrefs = context.getSharedPreferences("PhotoCollage", context.MODE_PRIVATE);
            SharedPreferences.Editor prefsEditor = mPrefs.edit();
            Gson gson = new Gson();
            String json = gson.toJson(collageList);
            prefsEditor.putString("myJson", json);
            prefsEditor.commit();
        }

该方法用于检索数组列表:-

public static List<String> loadSharedPreferencesLogList(Context context) {
        List<String> savedCollage = new ArrayList<String>();
        SharedPreferences mPrefs = context.getSharedPreferences("PhotoCollage", context.MODE_PRIVATE);
        Gson gson = new Gson();
        String json = mPrefs.getString("myJson", "");
        if (json.isEmpty()) {
            savedCollage = new ArrayList<String>();
        } else {
            Type type = new TypeToken<List<String>>() {
            }.getType();
            savedCollage = gson.fromJson(json, type);
        }

        return savedCollage;
    }
