SQLite Insert Data Failure

Question

Iveはログを記録して登録するデータベースを作成しましたが、うまくいきましたが、データベースを作成して収益を追加してもエラーは発生しませんでした。トーストメッセージが失敗したと言います。正しい変数は以下のコードを添付します。

DatabseHelperコードinsertIncomeはここに挿入する一つのimtryingのクラスのコードである：

} 

モデルクラスを拡張

public int iAmount; 
    public String iMethod; 
    public String iDate; 

    public Income(int iAmount, String iMethod, String iDate) { 
     iAmount = iAmount; 
     iMethod = iMethod; 
     iDate = iDate; 
    } 



    public int getiAmount() { 
     return iAmount; 
    } 

    public void setiAmount(int incAmount) { 
     this.iAmount = incAmount; 
    } 

    public String getiMethod() { 
     return iMethod; 
    } 

    public void setiMethod(String iMethod) { 
     this.iMethod = iMethod; 
    } 

    public String getiDate() { 
     return iDate; 
    } 

    public void setDate(String iDate) { 
     iDate = iDate; 
    } 






}

Answer 1

Createテーブルクエリの最後にcommaがありません。

使用：

private String CREATE_INCOME_TABLE = "CREATE TABLE " + TABLE_INCOME + " (ID INTEGER PRIMARY KEY AUTOINCREMENT, " + 
     " FIRSTNAME TEXT, LASTNAME TEXT, FAVFOOD TEXT);"; 

終わりに二重引用符内のカンマを追加 - すべてのテーブルクエリを作成します。
