ActiveAndroid SQLite異常'沒有這樣的表'

2014-11-03 78 views

我遇到了active-android的問題。 我試圖獲取用戶位置，乘客人數和總體方向。 我想使用activeAndroid將這些保存到名爲「Splits」的表中的手機存儲中。 但是每當我打電話給save()的方法，我都會得到一長串的錯誤。 我試圖重新安裝應用程序，並在清單中更改我的數據庫名稱，但這些解決方案都無效。 請記住我很新的節目，所以如果可能的話，像我5.謝謝:)ActiveAndroid SQLite異常'沒有這樣的表'

這裏是logcat的輸出

這裏是我的模型類的表

@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; 
    } 

}

我希望有人可以幫忙，我知道我張貼了一大堆，但我在這一點上越來越絕望。 在此先感謝

雖然晚了，希望對此有所幫助。

從ActiveAndroid的官方網頁在github上：

「這是因爲ActiveAndroid 只生成架構如果沒有現有數據庫文件。爲了在創建新模型後「重新生成」模式，最簡單的方法是將從模擬器中卸載應用程序，並允許其完全重新安裝。這是因爲這將清除數據庫文件和觸發ActiveAndroid重新創建基於項目的註釋模型中的表。」

是的，那是對的，你可以（而且我認爲應該）使用** <元數據android：name =「AA_DB_VERSION」android：value =「X」/> **在清單中（如文檔建議）並在您想要重新創建AA數據庫（默認X = 1）時增加X. – Arthez 2016-02-10 18:13:06

'從模擬器卸載應用程序，並允許它被完全重新安裝'工作..謝謝.. – 2016-02-22 08:28:02

似乎沒有表稱爲分裂到您的分貝。如果您對數據庫進行了更改，並且您正在一個真實設備（而非仿真器）中測試應用程序，則需要從設備（或至少其數據）中刪除應用程序以刷新數據庫。希望它有幫助=）

如前所述在這個問題我已經嘗試過，沒有運氣那裏我認爲我的模型類會爲我創建表？ 或者我得到activeandroid錯誤 – 2014-11-03 23:29:21

這還沒有其中一個在模擬器上的作品之一，但沒有 – 2016-12-07 12:36:21

您可能錯誤地配置了ActiveAndroid。在「常見問題」部分查看此tutorial。

這個初始化代碼：

ActiveAndroid.initialize(this);

進入應用程序類。所以你可以擴展Application類並在OnCreate中使用初始化。 像

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

確保你使用這個應用程序類在AndroidManifest.xml爲您的應用程序。即，

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

似乎你已經忘記了就在構造函數模型類調用super（）：

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

另一種可能是你沒有在你的Manifest文件中聲明你的Model類。

「如果構造函數沒有顯式調用超類構造函數，則Java編譯器會自動將調用插入到超類的無參構造函數中。」https://docs.oracle.com/javase /tutorial/java/IandI/super.html另外：「ActiveAndroid會瀏覽你所有的文件來找到你的Model類。」 – nasch 2015-10-21 17:40:19

增量您AA_DB_VERSION在你的清單。這將迫使ActiveAndroid再生架構。
