Android fetch data from database using arraylist

I'm fetching data from database using arraylist, but some double values convert into round off values.

public ArrayList<HashMap<String, String>> getTrackList() {
    SQLiteDatabase db = dbHelper.getReadableDatabase();
    String selectQuery = "SELECT * FROM TRACK";

    ArrayList<HashMap<String, String>> trackList = new ArrayList<HashMap<String, String>>();

    trackList.clear();

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

    if (cursor.moveToFirst()) {
        do {
            HashMap<String, String> track = new HashMap<String, String>();
            track.put("LATITUDE", cursor.getString(cursor.getColumnIndex("LATITUDE")));
            track.put("LONGITUDE", cursor.getString(cursor.getColumnIndex("LONGITUDE")));
            track.put("DATE", cursor.getString(cursor.getColumnIndex("DATE")));
            track.put("SPEED", cursor.getString(cursor.getColumnIndex("SPEED")));
            track.put("ACCURACY", cursor.getString(cursor.getColumnIndex("ACCURACY")));
            track.put("PROVIDER", cursor.getString(cursor.getColumnIndex("PROVIDER")));
            track.put("DISTANCE", cursor.getString(cursor.getColumnIndex("DISTANCE")));

            trackList.add(track);
        } while (cursor.moveToNext());
    }
    jSon = new Gson().toJson(trackList);
    cursor.close();
    return trackList;
}

here latitude, longitude and distance are double values, distance is same as database, but latitude or longitude are not same, suppose latitude is 22.8569874 in database but it returns 22.857
