Can I have arrayList of string in realm object android
提问by Salmaan
As we dont have any list data type in realm, how can we use ArrayList<String>in a realm object?
I had same question for the arrayLists of the custom models we make i.e. ArrayList<CustomModel>but for that I understand that we first have to make RealmObject of same Custom model using
由于我们在领域中没有任何列表数据类型，我们如何ArrayList<String>在领域对象中使用？
我对我们制作的自定义模型的 arrayLists 有同样的问题，即ArrayList<CustomModel>但为此我知道我们首先必须使用相同的自定义模型制作 RealmObject
public class CustomObject extends RealmObject {
private String name;
private String age;
}
and then I can use
然后我可以使用
private RealmList<CustomObject> customObjectList;
in another RealmObject
在另一个 RealmObject 中
Do i have to do same with arrayList of string?
1. Making String object
2. Use that object in Realm List
我必须对字符串的arrayList 做同样的事情吗？
1. 制作 String 对象
2. 在 Realm List 中使用该对象

Now it is possible to work with RealmList where T can be the following types: String, Integer, Boolean, Float, Double, Short, Long, Byte, byte[] and Date` (according to the official docs https://realm.io/docs/java/latest/#relationships, see Relationships -> List of Primitives)
现在可以使用 RealmList，其中 T 可以是以下类型：String、Integer、Boolean、Float、Double、Short、Long、Byte、byte[] 和 Date`（根据官方文档https://realm. io/docs/java/latest/#relationships，请参阅关系 -> 原语列表）
For example:
例如：
public RealmList<String> telephoneNumbers = new RealmList<>();
回答by Thomas Goyne
Yes, you have to manually box your strings in a StringObject. We'd like to add support for RealmList<String>, RealmList<Integer>, etc., but it's a long way out.
是的，您必须在 StringObject 中手动装箱您的字符串。我们想添加对RealmList<String>、RealmList<Integer>等的支持，但还有很长的路要走。
