ActiveAndroid不保存表

Question

我正在使用ActiveAndroid库来使用数据库，但是当我尝试保存对象时，它说没有这样的表。 我尝试过更新数据库版本并卸载我的应用程序，但是仍然没有运气。 任何帮助将不胜感激。 谢谢！

这些是错误：

这是我的代码：

AlarmModel.java （GenericModel扩展了com.activeandroid.Model；它仅包含CRUD操作）

package com.martyawesome.smartyalarm.models;

import java.util.List;

import com.activeandroid.annotation.Column;
import com.activeandroid.annotation.Table;
import com.cmai.al.models.GenericModel;

@Table(name = "alarm")
public class AlarmModel extends GenericModel<Object> {

@Column(name = "alarmId")
public int id;

@Column(name = "name")
public String name;

@Column(name = "hour")
public int timeHour;

@Column(name = "minute")
public int timeMinute;

@Column(name = "sunday")
public int sunday;

@Column(name = "monday")
public int monday;

@Column(name = "tuesday")
public int tuesday;

@Column(name = "wednesday")
public int wednesday;

@Column(name = "thursday")
public int thursday;

@Column(name = "friday")
public int friday;

@Column(name = "saturday")
public int saturday;

@Column(name = "weekly")
public int repeatWeekly;

@Column(name = "tone")
public String alarmTone;

@Column(name = "isEnabled")
public int isEnabled;

@Column(name = "isOnSnooze")
public int isOnSnooze;

@Column(name = "snoozeTime")
public int snoozeTime;

public List<AlarmModel> getAll() {
    return super.getAll(getCurrentClass());
}

public void update(AlarmModel model) {
    super.update(getCurrentClass(), model);
}

public void updateAll(List<AlarmModel> models) {
    super.updateAll(getCurrentClass(), models);
}

public void deleteAll() {
    super.deleteAll(getCurrentClass());
}

}

AndroidManifest.xml

...
<application android:name="com.activeandroid.app.Application"
...
<meta-data
    android:name="AA_DB_NAME"
    android:value="smartyalarm.db" />
<meta-data
    android:name="AA_DB_VERSION"
    android:value="2" />
</application>

Answer 1

我认为您的AlarmModel类应该扩展com.activeandroid.Model ，而不是GenericModel<Object> 。

Answer 2

您的模型类需要实现Serializable。
