私はこれにかなりイライラしています。データベース内にいくつかの文字列値を入れようとしましたが、値を取得するフィールドは 4 つだけです。違う

次のコード:

データを挿入する場所：

            DatabaseHandler db = new DatabaseHandler(this);

        db.deleteStats(5);
        db.deleteStats(6);

        db.addStats(new Stats(  "O Teste 01", 
                                "teste 1.gpx", 
                                "00:10:00",
                                "100.00", 
                                "10.0",
                                "10.0", 
                                "20.0", 
                                "20", 
                                "1", 
                                "10", 
                                "100", 
                                "1", 
                                "2012-07-15 12:00:00"));

データを sqlite に挿入する関数:

    public void addStats(Stats st) 
{
    SQLiteDatabase db = this.getWritableDatabase();

    ContentValues values = new ContentValues();

    values.put(DatabaseHandler.COLUMN_NAME, st.getmName());
    values.put(DatabaseHandler.COLUMN_FILENAME, st.getmFilename());
    values.put(DatabaseHandler.COLUMN_TOTAL_TIME, st.getmTotalTime());
    values.put(DatabaseHandler.COLUMN_TOTAL_DISTANCE, st.getmTotalDistance());
    values.put(DatabaseHandler.COLUMN_AVG_SPEED, st.getmAvgSpeed());
    values.put(DatabaseHandler.COLUMN_MIN_SPEED, st.getmMinSpeed());
    values.put(DatabaseHandler.COLUMN_MAX_SPEED, st.getmMaxSpeed());
    values.put(DatabaseHandler.COLUMN_ACUM_ALTITUDE, st.getmAcumAltitude());
    values.put(DatabaseHandler.COLUMN_MIN_ALTITUDE, st.getmMinAltitude());
    values.put(DatabaseHandler.COLUMN_MAX_ALTITUDE, st.getmMaxAltitude());
    values.put(DatabaseHandler.COLUMN_CALORIES, st.getmCalories());
    values.put(DatabaseHandler.COLUMN_MOD, st.getmMod());
    values.put(DatabaseHandler.COLUMN_DATE, st.getmDate());

    // Adiciona linha
    db.insert(DatabaseHandler.TABLE_STATS, null, values);
    db.close(); // fechando a conexão à base de dados
}

前もって感謝します！

わかりました、悪い...

私はすべてのフィールドを取得していませんでした! ああああ

とにかくありがとう

 public List<Stats> getAllStats() {
    List<Stats> statsList = new ArrayList<Stats>();
    // Select All Query
    String selectQuery = "SELECT  * FROM " + TABLE_STATS;

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

    // looping through all rows and adding to list
    if (cursor.moveToFirst()) {
        do {
            Stats linha = new Stats();
            linha.setmId(Integer.parseInt(cursor.getString(0)));
            linha.setmName(cursor.getString(1));
            linha.setmFilename(cursor.getString(2));
            linha.setmTotalDistance(cursor.getString(3));
            linha.setmAvgSpeed(cursor.getString(4));
            linha.setmMinSpeed(cursor.getString(5));
            linha.setmMaxSpeed(cursor.getString(6));
            linha.setmAcumAltitude(cursor.getString(7));
            linha.setmMinAltitude(cursor.getString(8));
            linha.setmMaxAltitude(cursor.getString(9));
            linha.setmCalories(cursor.getString(10));
            linha.setmMod(cursor.getString(11));
            linha.setmDate(cursor.getString(12));
            // Adding contact to list
            statsList.add(linha);
        } while (cursor.moveToNext());
    }

    // return estatísticas list
    return statsList;
