androd使用Realm实现数据存储到手机数据库

但是这个对象类要是继承RealmObject ；
publicclassDogextendsRealmObject{
private String name;
privateint age;
@PrimaryKey
private String id;
public String getName(){
return name;
}
publicvoidsetName(String name){
this.name = name;
}
publicintgetAge(){
return age;
}
publicvoidsetAge(int age){
this.age = age;
}
public String getId() {
return id;
}
publicvoidsetId(String id){
this.id = id; }}
