Question

我试图从结果中获取name属性。到处看，无法弄清楚。当我登录时，我得到了这个：

[Person {id = 0，name =＆＃39; Jonathon＆＃39;，age = 21}]

如何仅访问名称，而不是完整结果？

protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    Realm realm = Realm.getDefaultInstance();

    realm.executeTransaction(new Realm.Transaction() {
        @Override
        public void execute(Realm realm) {
            Person person = realm.createObject(Person.class);
            person.setName("Jonathon");
            person.setAge(21);
        }
    });

    RealmQuery<Person> query = realm.where(Person.class).equalTo("name", "Jonathon");
    RealmResults<Person> result = query.findAll();

    Log.d("Result", result.toString());
}

Answer 1

RealmQuery<Person> query = realm.where(Person.class).equalTo("name", "Jonathon");
RealmResults<Person> result = query.findAll();

Person person = result.get(0);
Log.d("Result", person.getName());

Answer 2

您的查询似乎运行正常。
