In realm, how to query from a RealmList (Android)

Question

Check out following classes:

class Person{
    int id;
    String name;
    RealmList<Mail> mails;
    ...
}

class Mail{
    int id;
    String content;
    ...
}

I have a Person object (ie: mPerson) and I am accessing all Mails of the Person object by mPerson.getMails(). Till here everything is cool.

Here is the question: Is there way to query over the returned list such as findAllSortedAsync()?

Solution

Just use RealmList.where() to create a query. You can find document here

For example: RealmList<Mail> mails = person.getMails(); RealmResults<Mail> results = mails.where().equalTo("id", 1).findAllSortedAsync();
