logcatはどこですか？投稿してください。 – Vucko

これは、人々がSQLを書くことを許可してはいけない理由です。 – njzk2

アプリケーションのこの後の「姓」列を追加しましたか？はいの場合は、デバイスからアプリケーションを完全にアンインストールしてからもう一度インストールして実行してください。 – Vickyexpert

あなたの作成テーブルクエリはそれを台無しにしています。列名とその型は間にスペースを入れ、コンマもありません。これを使用する

@Override 
public void onCreate(SQLiteDatabase db) { 
    String CREATE_AttendanceList_TABLE = "CREATE TABLE " + TABLE_AttendanceList + "(" 
     + KEY_ID + " INTEGER PRIMARY KEY," 
     + KEY_reg_no + " TEXT," 
     + KEY_firstname + " TEXT," 
     + KEY_lastname + " TEXT," 
     + KEY_surname + " TEXT" + ")"; 
    db.execSQL(CREATE_AttendanceList_TABLE); 
}

最初にアプリをアンインストールしてから、更新されたコードを実行する必要があります。

ありがとう...私は、プロジェクトをクリアして再構築しましたが、logcatにも同じエラーがあります。 –

あなたのデバイスから古いアプリをインストールしましたか？古いアプリをインストールする必要があります。 – Rohit5k2

ありがとうございます。私は今、より多くのエラー（構文エラー）を持っていますが、私は "テーブルAttendanceListは、姓の名前の列を持っていない"と表示されません幸せです。 –
