android - SugarORM - 'listall' 返回空列表

Question

我有这门课:

public class ProfileData extends SugarRecord {
@Expose
public Data data;

public ProfileData(Data data) {
    this.data = data;
}

public static class Data {
    public long id;
    @Expose
    public String email;
    @Expose
    public String name;
    @Expose
    public String surname;
    @Expose
    public String address;
    @Expose
    public String city;
    @Expose
    public long pesel;
    @Expose
    public long phone;
    @Expose
    public long userId;
    @Expose
    public long clubId;
    @Expose
    public String fullName;
    @Expose
    public long clientStatusId;
    @Expose
    public String provider;
    @Expose
    public String uid;
    @Expose
    public boolean gender;


    public Data(long id, String email, String name, String surname, String address, String city,
                long pesel, long phone, long userId, long clubId, String fullName,
                long clientStatusId, String provider, String uid, boolean gender) {
        this.id = id;
        this.email = email;
        this.name = name;
        this.surname = surname;
        this.address = address;
        this.city = city;
        this.pesel = pesel;
        this.phone = phone;
        this.userId = userId;
        this.clubId = clubId;
        this.fullName = fullName;
        this.clientStatusId = clientStatusId;
        this.provider = provider;
        this.uid = uid;
        this.gender = gender;
    }
}

我使用来自 JSON(使用 Gson)的数据填充此类。然后我调用 save() 方法(“数据”对象是 ProfileData 的一个实例):

data.save();

我的下一步是:

List<ProfileData> profileList = ProfileData.listAll(ProfileData.class);

并且 profileList 是空的。

我将这一行放入 AndroidManifest:

<meta-data
        android:name="DATABASE"
        android:value="sugar_example_my.db" />
    <meta-data
        android:name="VERSION"
        android:value="2" />
    <meta-data
        android:name="QUERY_LOG"
        android:value="true" />
    <meta-data
        android:name="DOMAIN_PACKAGE_NAME"
        android:value="com.example.my" />

最后在我的 App 类中我放了这行:

SugarContext.init(this);

有什么建议吗？

编辑:

我通过将 public Data() {} 添加到 Data 类并移动

解决了这个问题

extends SugarRecord

从 ProfileData 到数据。

我认为问题在于你的列表应该是List<Data>
