我正在使用ormlite-core-4.46和ormlite-android-4.46，我仍然收到此错误。下面是我的异常跟踪日志：

这是具有外国集合的类：

@DatabaseTable(tableName = "activity")
public class CardActivity {

    @DatabaseField(generatedId = true)
    private int _id;

    @DatabaseField
    private String name;

    @DatabaseField
    private Date start;

    @DatabaseField
    private Date end;

    @ForeignCollectionField(eager = false)
    private ForeignCollection<Relation_Participants> participants;

这是具有上述类的外来字段的类：

@DatabaseTable(tableName = "relation_participants")
public class Relation_Participants {
    @DatabaseField(generatedId = true)
    private int _id;

    @DatabaseField(foreign = true)
    private CardActivity activity;

    @DatabaseField(foreign = true)
    private Player player;

有人知道问题是??? 这真让我疯狂!!

我假设android config.txt为ormlite_config.txt，所以我删除了文件，并再次生成文件，但问题仍然存在。以下是文件：

Answer 1

java.lang.IllegalArgumentException: Field FieldType:name=activity,
    class=Relation_Participants is a primitive class
    class com.lordcardrecorder.model.CardActivity but marked as foreign

因此，ORMLite认为您的Relation_Participants类是原始类型。我怀疑问题是Android ormlite_config.txt文件中的无效信息，它会缓存字段和类型信息。我会立即删除此文件，然后重新运行您的程序，看它是否有效。如果它没有，那么你需要重新生成它。

如果问题仍然存在，请发布列出ormlite_config.txt字段的Relation_Participants文件部分。是说它是原始的吗？

IllegalArgumentException：字段xxx是基本类类xxx，但标记为外部
