使用Kotlin和GSON:

fun <T> SharedPreferences.writeList(gson: Gson, key: String, data: List<T>) {
    val json = gson.toJson(data)
    edit { putString(key, json) }
}

inline fun <reified T> SharedPreferences.readList(gson: Gson, key: String): List<T> {
    val json = getString(key, "[]") ?: "[]"
    val type = object : TypeToken<List<T>>() {}.type
    
    return try {
        gson.fromJson(json, type)
    } catch(e: JsonSyntaxException) {
        emptyList()
    }
}

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

别忘了实现Serializable:

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

最好的方法是使用GSON转换为JSOn字符串并保存此字符串到SharedPreference。 我还使用这种方式缓存响应。

我的utils类保存列表到SharedPreferences

public class SharedPrefApi {
    private SharedPreferences sharedPreferences;
    private Gson gson;

    public SharedPrefApi(Context context, Gson gson) {
        this.sharedPreferences = context.getSharedPreferences(PREFS_NAME, Context.MODE_PRIVATE);
        this.gson = gson;
    } 

    ...

    public <T> void putList(String key, List<T> list) {
        SharedPreferences.Editor editor = sharedPreferences.edit();
        editor.putString(key, gson.toJson(list));
        editor.apply();
    }

    public <T> List<T> getList(String key, Class<T> clazz) {
        Type typeOfT = TypeToken.getParameterized(List.class, clazz).getType();
        return gson.fromJson(getString(key, null), typeOfT);
    }
}

使用

// for save
sharedPrefApi.putList(SharedPrefApi.Key.USER_LIST, userList);

// for retrieve
List<User> userList = sharedPrefApi.getList(SharedPrefApi.Key.USER_LIST, User.class);

下面的代码是公认的答案，为新手(我)多写几行，例如。说明了如何将set类型对象转换回arrayList，并提供了关于`之前操作的附加指导。putStringSet'和。getstringset '。(谢谢你邪恶)

// shared preferences
   private SharedPreferences preferences;
   private SharedPreferences.Editor nsuserdefaults;

// setup persistent data
        preferences = this.getSharedPreferences("MyPreferences", MainActivity.MODE_PRIVATE);
        nsuserdefaults = preferences.edit();

        arrayOfMemberUrlsUserIsFollowing = new ArrayList<String>();
        //Retrieve followers from sharedPreferences
        Set<String> set = preferences.getStringSet("following", null);

        if (set == null) {
            // lazy instantiate array
            arrayOfMemberUrlsUserIsFollowing = new ArrayList<String>();
        } else {
            // there is data from previous run
            arrayOfMemberUrlsUserIsFollowing = new ArrayList<>(set);
        }

// convert arraylist to set, and save arrayOfMemberUrlsUserIsFollowing to nsuserdefaults
                Set<String> set = new HashSet<String>();
                set.addAll(arrayOfMemberUrlsUserIsFollowing);
                nsuserdefaults.putStringSet("following", set);
                nsuserdefaults.commit();
