將數據插入到第二個表``我使用SQLite Database.I已經創建了兩個tables.first表是用戶表，它成功地創建和inserted.but在我的第二個表還成功創建，但不insert.this是我進步problem.Thank ..無法在Android的

這是OnClick事件在這裏嘗試調用插件的方法是存在於數據庫類

public void onClick(View v) { 
    String itemname; 
    String price; 
    int position; 
    if(v.getId()==R.id.id_btn_submit){ 
     //insert the price into database 
      itemname =mEditItemName.getText().toString(); 
      price =(mEditPrice.getText().toString()); 
      position=spinner.getSelectedItemPosition(); 

     if(itemname.isEmpty()){ 
      mEditItemName.setError("enter the item name"); 

     }else if(price.isEmpty()){ 
      mEditPrice.setError("pls enter the price"); 
     }else{ 
      dataBase=new DataBase(this); 
      position=position+1; 
      mItemId= dataBase.insertAll(itemname,price, String.valueOf(position)); 
     } 
     mEditItemName.setText(""); 
     mEditPrice.setText(""); 
     Log.d("bucky ","succefully insert "); 

    }

這是插入方法

public long insertAll(String itemname ,String price,String itemcategory){ 
    SQLiteDatabase sqLiteDatabase=databasehelper.getWritableDatabase(); 
    ContentValues content=new ContentValues(); 
    content.put(databasehelper.mITEMNAME, itemname); 
    content.put(databasehelper.mITEMPRICE, price); 
    content.put(databasehelper.mITEMCATEGORY, itemcategory); 
    long id=sqLiteDatabase.insert(databasehelper.mTABLEMENUITEM,null,content); 
    Log.d("bucky insert item", String.valueOf(id)); 
    return id; 
}

CREATE語句和UPDATE語句

public class DataBaseHelper extends SQLiteOpenHelper{ 
    private final static String mDATABASENAME="foodpanta"; 
    private final static int mVERSION=9; 
    private Context context; 
    //user information table

    public DataBaseHelper(Context context) { 
     super(context, mDATABASENAME, null, mVERSION); 
     this.context=context; 
     Message.message(context,"on constructor called"); 

    } 

    @Override 
    public void onCreate(SQLiteDatabase db) { 
     db.execSQL(mCREATETABLEUSER); 

     db.execSQL(mCREATETABLEMENU); 
     Message.message(context, "on create called"); 

    } 

    @Override 
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) { 
     db.execSQL("DROP TABLE IF EXISTS " + mTABLEUSERDETAIL); 

     db.execSQL("DROP TABLE IF EXISTS " + mTABLEMENUITEM); 
     Message.message(context, "on upgrade called"); 
     onCreate(db); 

    } 

}

你可以發佈你的堆棧跟蹤？ – Fustigador

我調試了代碼，發現id值是-1。 – rafeek

這是因爲它沒有插入。插入將返回插入值的PK值。 – Fustigador

INSERT INTO menuitem(item category,itemprice,itemname) VALUES (?,?,?)

還有就是你的錯誤，「項目類別」應爲「itemcategory」，你增加了一個空間的地方，和SQLite認爲你只是試圖插入四個值代替三個。

具體來說，在這裏：

private final static String mITEMCATEGORY="item category";
