public List getAllNapChecks() に列を設定するたびに、何が問題なのかわかりません。バグが発生し、列が5つしかないと言われます。何時間もこれを行っていることを知りません..よろしくお願いします..たださらに必要かどうかを伝える

public List<NapCheck> getAllNapChecks() {
    List<NapCheck> NapList = new ArrayList<NapCheck>();
    // Select All Query
    String selectQuery = "SELECT  * FROM " + TABLE_NapS;

    SQLiteDatabase db = this.getWritableDatabase();
    Cursor cursor = db.rawQuery(selectQuery, null);

    // looping through all rows and adding to list
    if (cursor.moveToFirst()) {
        do {
            NapCheck nap = new NapCheck();
            nap.setID(Integer.parseInt(cursor.getString(0)));
            nap.setName(cursor.getString(1));
            nap.setMall(cursor.getString(2));
            nap.setLatit(cursor.getString(3));
            nap.setLongit(cursor.getString(4));

この行は、ほとんどの場合問題が発生する場所です..

            nap.setLongit(cursor.getString(5));

            // Adding nap to list
            NapList.add(nap);
        } while (cursor.moveToNext());
    }

    // return nap list
    return NapList;
}

KEY_INTER（最後のフィールド）の後の不要なスペースとカンマが問題の変更だと思います。

Cursor cursor = db.query(TABLE_NapS, new String[] { KEY_ID,
        KEY_NAME, KEY_MALL, KEY_LATIT, KEY_LONGIT, KEY_INTER}, KEY_ID + "=?",
        new String[] { String.valueOf(id) }, null, null, null, null);

おそらく、これはあなたが作成した最初の DB スキーマではありません。

DB スキーマを編集する場合は、DB バージョンを増やす必要があります。それ以外の場合、 onUpdate() は呼び出されません。

試す：

private static final int DATABASE_VERSION = 2;
