字段槽0，-1的錯誤請求。 = numRows行1，爲numColumns = 8

我嘗試以檢索針對Android DATABSE整個數據... 字段槽0，-1的錯誤請求。 = numRows行1，爲numColumns = 8

SQLite的查詢： -

Cursor c = db.rawQuery("SELECT * FROM stud",null);

但例外： -

@kalpana，請你分享一下你的代碼（其實我的程序控制器沒有進入getChildCursor（）方法。 –

哈哈經過2天的工作，在這種情況下，今天我的前輩（Vijar Sir）建議我將id（primary_Key）名稱爲：_id &其運行成功，

現在如果你說爲什麼實施PHONE_CONTACT後：here比上面盤旋Contacts._ID，你會發現_id與它關聯的字符串。

private static final String[] CONTACTS_PROJECTION = new String[] 
{ 
    Contacts._ID, 
    Contacts.DISPLAY_ 
};
