ActiveAndroid SQLite异常'没有这样的表'

2014-11-03 82 views

我遇到了active-android的问题。 我试图获取用户位置，乘客人数和总体方向。 我想使用activeAndroid将这些保存到名为“Splits”的表中的手机存储中。 但是每当我打电话给save()的方法，我都会得到一长串的错误。 我试图重新安装应用程序，并在清单中更改我的数据库名称，但这些解决方案都无效。 请记住我很新的节目，所以如果可能的话，像我5.谢谢:)ActiveAndroid SQLite异常'没有这样的表'

这里是logcat的输出

这里是我的模型类的表

@Table(name = "Splits") 
public class Splits extends Model { 
    @Column(name = "startLat") 
    public double startLat; 
    @Column(name = "startLong") 
    public double startLong; 
    @Column(name = "passengers") 
    public int passengers; 
    @Column(name = "direction") 
    public String direction; 


    public Splits() 
    { 
     super(); 
    } 

    public Splits(double startLat, double startLong, int passengers, String direction) 
    { 
     this.startLat = startLat; 
     this.startLong = startLong; 
     this.passengers = passengers; 
     this.direction = direction; 
    }

虽然晚了，希望对此有所帮助。

从ActiveAndroid的官方网页在github上：

“这是因为ActiveAndroid 只生成架构如果没有现有数据库文件。为了在创建新模型后“重新生成”模式，最简单的方法是将从模拟器中卸载应用程序，并允许其完全重新安装。这是因为这将清除数据库文件和触发ActiveAndroid重新创建基于项目的注释模型中的表。”

是的，那是对的，你可以（而且我认为应该）使用** <元数据android：name =“AA_DB_VERSION”android：value =“X”/> **在清单中（如文档建议）并在您想要重新创建AA数据库（默认X = 1）时增加X. – Arthez 2016-02-10 18:13:06

'从模拟器卸载应用程序，并允许它被完全重新安装'工作..谢谢.. – 2016-02-22 08:28:02

似乎没有表称为分裂到您的分贝。如果您对数据库进行了更改，并且您正在一个真实设备（而非仿真器）中测试应用程序，则需要从设备（或至少其数据）中删除应用程序以刷新数据库。希望它有帮助=）

如前所述在这个问题我已经尝试过，没有运气那里我认为我的模型类会为我创建表？ 或者我得到activeandroid错误 – 2014-11-03 23:29:21

这还没有其中一个在模拟器上的作品之一，但没有 – 2016-12-07 12:36:21

您可能错误地配置了ActiveAndroid。在“常见问题”部分查看此tutorial。

这个初始化代码：

ActiveAndroid.initialize(this);

进入应用程序类。所以你可以扩展Application类并在OnCreate中使用初始化。 像

public class MyApplication extends Application{ 
    @Override 
    public void onCreate() { 
     super.onCreate(); 
     ActiveAndroid.initialize(this); 
    } 
}

确保你使用这个应用程序类在AndroidManifest.xml为您的应用程序。即，

<application android:name="com.exampleapp.MyApplication" ...>

参见：https://github.com/pardom/ActiveAndroid/wiki/Getting-started

似乎你已经忘记了就在构造函数模型类调用super（）：

public Splits(double startLat, double startLong, int passengers, String direction) 
{ 
    super(); 
    this.startLat = startLat; 
    this.startLong = startLong; 
    this.passengers = passengers; 
    this.direction = direction; 
}

另一种可能是你没有在你的Manifest文件中声明你的Model类。

“如果构造函数没有显式调用超类构造函数，则Java编译器会自动将调用插入到超类的无参构造函数中。”https://docs.oracle.com/javase /tutorial/java/IandI/super.html另外：“ActiveAndroid会浏览你所有的文件来找到你的Model类。” – nasch 2015-10-21 17:40:19

增量您AA_DB_VERSION在你的清单。这将迫使ActiveAndroid再生架构。
