为什么我的User类集成了BaseObservable，里面写了@Bindable没有生成BR

[bethinner]

public class User extends BaseObservable{
private String firstName;
private String lastName;

@Bindable
public String getFirstName() {
    return firstName;
}

public void setFirstName(String firstName) {
    this.firstName = firstName;
    notifyPropertyChanged(BR.firstName);
}
@Bindable
public String getLastName() {
    return lastName;
}

public void setLastName(String lastName) {
    this.lastName = lastName;
    notifyPropertyChanged(BR.lastName);
}
@Bindable
public String getTotalName() {
    return this.firstName  + this.lastName;
}

}

BR,用不了
