领域和Android数据绑定

我试图在我的应用中使用Realm,但没有成功。问题似乎是我在同一个应用程序中使用数据绑定和Realm。

objectif,让用户使用View输入我通过数据绑定获得的一些数据,并插入到Realm数据库中

我有以下错误:

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)

这是我的模块build.gradle

}

这是我的项目build.gradle

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

  }
  allprojects {
      repositories {
       jcenter()
     }
  }

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

这是我使用Realm和DataBinding的活动

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);

我在侦听器中的某些代码行使用

  realm.commitTransaction();

我不明白这是什么问题......

此致

1 个答案:

答案 0 :(得分:1)

来自文档:

  

字段类型

     

Realm支持以下字段类型:boolean,byte,short,int,long,float,double,String,Date和byte []。整数类型byte,short,int和long都映射到Realm中的相同类型(实际上很长)。

     

此外,支持RealmObjectRealmList<? extends RealmObject>的子类来建模关系。

嗯,你也有这个:

 private ObservableField<String> nbCaracteristicPointAvailableStringOb;

这不是受支持的RealmModel字段,因此不会起作用。您必须添加@Ignore注释。

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

此外,您可以测试这是否可行,但我认为使用静态工厂方法更安全,而不是在也使用的默认构造函数中初始化所有这些列表和内容实例化托管代理时。

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

(在完全不相关的旁注中,我不知道为什么这个类是Serializable,你为什么要通过ObjectOutputStream抛出一个RealmObject?)

编辑:你也可以尝试通过添加android-apt插件来强制它工作。

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"
    }
}

然后

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'
