使用这个自定义类:

public class SharedPreferencesUtil {

    public static void pushStringList(SharedPreferences sharedPref, 
                                      List<String> list, String uniqueListName) {

        SharedPreferences.Editor editor = sharedPref.edit();
        editor.putInt(uniqueListName + "_size", list.size());

        for (int i = 0; i < list.size(); i++) {
            editor.remove(uniqueListName + i);
            editor.putString(uniqueListName + i, list.get(i));
        }
        editor.apply();
    }

    public static List<String> pullStringList(SharedPreferences sharedPref, 
                                              String uniqueListName) {

        List<String> result = new ArrayList<>();
        int size = sharedPref.getInt(uniqueListName + "_size", 0);

        for (int i = 0; i < size; i++) {
            result.add(sharedPref.getString(uniqueListName + i, null));
        }
        return result;
    }
}

使用方法:

SharedPreferences sharedPref = getPreferences(Context.MODE_PRIVATE);
SharedPreferencesUtil.pushStringList(sharedPref, list, getString(R.string.list_name));
List<String> list = SharedPreferencesUtil.pullStringList(sharedPref, getString(R.string.list_name));

您可以将其转换为Map Object来存储它，然后在检索SharedPreferences时将值更改回ArrayList。

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;
    }

为什么不把数组列表放在应用程序类上呢?它只有在应用被杀死时才会被销毁，所以，只要应用可用，它就会一直存在。

别忘了实现Serializable:

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

还有Kotlin:

fun SharedPreferences.Editor.putIntegerArrayList(key: String, list: ArrayList<Int>?): SharedPreferences.Editor {
    putString(key, list?.joinToString(",") ?: "")
    return this
}

fun SharedPreferences.getIntegerArrayList(key: String, defValue: ArrayList<Int>?): ArrayList<Int>? {
    val value = getString(key, null)
    if (value.isNullOrBlank())
        return defValue
    return ArrayList (value.split(",").map { it.toInt() }) 
}
