문자열 값 삽입 sqlite return null android

Question

나는 이것에 꽤 좌절감을 느낀다. 데이터베이스에 일부 문자열 값을 넣으려고 시도했지만 값이 4 개만 필드에 입력되었습니다. name = "O Teste 01"correct, total_time = "teste 1.gpx"wrong, total_distance "00:10:00" 일 "100"잘못된

다음 코드 : 내가 데이터를 삽입

:

  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"));

sqlite가에 데이터를 삽입 할 수있는 기능 : 미리

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 
}

좋아 ... 내 나쁜

나는 모든 필드를 받고되지 않았습니다! 아아

덕분에 어쨌든

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; 
}
