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;
    }

/**
 *     Save and get ArrayList in SharedPreference
 */

JAVA:

public void saveArrayList(ArrayList<String> list, String key){
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(activity);
    SharedPreferences.Editor editor = prefs.edit();
    Gson gson = new Gson();
    String json = gson.toJson(list);
    editor.putString(key, json);
    editor.apply();    

}

public ArrayList<String> getArrayList(String key){
    SharedPreferences prefs = PreferenceManager.getDefaultSharedPreferences(activity);
    Gson gson = new Gson();
    String json = prefs.getString(key, null);
    Type type = new TypeToken<ArrayList<String>>() {}.getType();
    return gson.fromJson(json, type);
}

科特林

fun saveArrayList(list: java.util.ArrayList<String?>?, key: String?) {
    val prefs: SharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity)
    val editor: Editor = prefs.edit()
    val gson = Gson()
    val json: String = gson.toJson(list)
    editor.putString(key, json)
    editor.apply()
}

fun getArrayList(key: String?): java.util.ArrayList<String?>? {
    val prefs: SharedPreferences = PreferenceManager.getDefaultSharedPreferences(activity)
    val gson = Gson()
    val json: String = prefs.getString(key, null)
    val type: Type = object : TypeToken<java.util.ArrayList<String?>?>() {}.getType()
    return gson.fromJson(json, type)
}

您可以将其转换为JSON字符串，并将字符串存储在SharedPreferences中。

正如@nirav所说，最好的解决方案是使用Gson实用工具类将其作为json文本存储在sharedpreferences中。下面是示例代码:

//Retrieve the values
Gson gson = new Gson();
String jsonText = Prefs.getString("key", null);
String[] text = gson.fromJson(jsonText, String[].class);  //EDIT: gso to gson


//Set the values
Gson gson = new Gson();
List<String> textList = new ArrayList<String>(data);
String jsonText = gson.toJson(textList);
prefsEditor.putString("key", jsonText);
prefsEditor.apply();

Android sharedpreferences允许您将基本类型(Boolean, Float, Int, Long, String和StringSet，自API11以来可用)作为xml文件保存在内存中。

任何解决方案的关键思想都是将数据转换为这些基本类型之一。

我个人喜欢将my list转换为json格式，然后将其保存为SharedPreferences值中的字符串。

为了使用我的解决方案，你必须添加谷歌gsonlib。

在gradle中只需添加以下依赖项(请使用谷歌的最新版本):

compile 'com.google.code.gson:gson:2.6.2'

保存数据(HttpParam是你的对象):

List<HttpParam> httpParamList = "**get your list**"
String httpParamJSONList = new Gson().toJson(httpParamList);

SharedPreferences prefs = getSharedPreferences(**"your_prefes_key"**, Context.MODE_PRIVATE);
SharedPreferences.Editor editor = prefs.edit();
editor.putString(**"your_prefes_key"**, httpParamJSONList);

editor.apply();

检索数据(HttpParam是你的对象):

SharedPreferences prefs = getSharedPreferences(**"your_prefes_key"**, Context.MODE_PRIVATE);
String httpParamJSONList = prefs.getString(**"your_prefes_key"**, ""); 

List<HttpParam> httpParamList =  
new Gson().fromJson(httpParamJSONList, new TypeToken<List<HttpParam>>() {
            }.getType());
