Realm and Android DataBinding

Question

Я пытаюсь использовать Realm в своем приложении, но безуспешно. Проблема заключается в том, что я использую привязку данных и Realm в одном приложении.

Objectif, это позволяет пользователю использовать View, чтобы ввести некоторые данные, которые я получаю с привязки данных, и вставить в базу данных Realm

У меня есть следующее сообщение об ошибке:

Character is not part of the schema for this Realm 
    at io.realm.internal.modules.CompositeMediator.getMediator(CompositeMediator.java:172) 
    at io.realm.internal.modules.CompositeMediator.getTableName(CompositeMediator.java:90) 
    at io.realm.RealmSchema.getTable(RealmSchema.java:296) 
    at io.realm.Realm.createObjectInternal(Realm.java:817) 
    at io.realm.Realm.createObject(Realm.java:801)

    } 
    } 

    task clean(type: Delete) { 
     delete rootProject.buildDir

Вот моя деятельность, которые используют Сферу и DataBinding

final ActivityCreateBinding binding = DataBindingUtil.setContentView(this, R.layout.activity_create); 
    ButterKnife.bind(binding.getRoot()); 
    Realm.init(getApplicationContext()); 
    RealmConfiguration config = new RealmConfiguration.Builder().build(); 
    realm = Realm.getInstance(config); 
    realm.beginTransaction(); 
    character = realm.createObject(Character.class); 
    binding.setCharacter(character); 

и некоторые строки кода ниже в качестве слушателя я использую

realm.commitTransaction(); 

Я не understant чем проблема ...

Answer 1

Из документации:

Field types

Realm supports the following field types: boolean, byte, short, int, long, float, double, String, Date and byte[]. The integer types byte, short, int, and long are all mapped to the same type (long actually) within Realm.

Moreover, subclasses of RealmObject and RealmList<? extends RealmObject> are supported to model relationships.

Ну, у вас есть это:

private ObservableField<String> nbCaracteristicPointAvailableStringOb; 

Это не поддерживается поле RealmModel, так что это не сработает. Вы должны добавить аннотацию @Ignore.

@RealmClass 
public class Character extends RealmObject implements Serializable 
    //... 
    @Ignore 
    private ObservableField<String> nbCaracteristicPointAvailableStringOb; 

---

Кроме того, вы можете проверить, если это будет работать на всех, но я думаю, что было бы безопаснее использовать статический фабричный метод вместо инициализации всех этих списков и прочего в конструкторе по умолчанию, также используется при создании управляемых прокси.

public static Character create() { 
    Character character = new Character(); 
    character.initCharacter(); 
    return character; 
} 

(и на совершенно несвязанной заметка на полях, я не знаю, почему этот класс Serializable, почему вы хотите бросить RealmObject через ObjectOutputStream ...?)

EDIT: вы также можете попробовать заставить его работать, добавив плагин android-apt.

buildscript { 
    repositories { 
     jcenter() 
    } 
    dependencies { 
     classpath 'com.android.tools.build:gradle:2.3.0-alpha1' 
     classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8' 
     classpath "io.realm:realm-gradle-plugin:2.2.1" 
    } 
} 

Тогда

apply plugin: 'com.android.application' 
apply plugin: 'com.neenbedankt.android-apt' 
apply plugin: 'realm-android' 

//... 

compile 'com.jakewharton:butterknife:8.4.0' 
// ... 
apt 'com.jakewharton:butterknife-compiler:8.4.0'
