Get and Parse CSV file in android

I'm trying to get a csv file from http://download.finance.yahoo.com/d/quotes.csv?s=msft&f=sl1p2 then parse it so that I can get the price and the price changed into an object that sets both properties. Is there a way that I can do this with the android libraries?

Edit: Here's the current state of the union (not working):

HttpClient httpClient = new DefaultHttpClient();
        HttpContext localContext = new BasicHttpContext();
        HttpGet httpGet = new HttpGet(uri);
        HttpResponse response = httpClient.execute(httpGet, localContext);
        String result = "";

        BufferedReader reader = new BufferedReader(new InputStreamReader(response.getEntity().getContent()));

        String line = null;
        while ((line = reader.readLine()) != null){
              result += line + "\n";
              String[] RowData = result.split("\n");
              Str开发者_高级运维ing name = RowData[0];
              String price = RowData[1];
              String change = RowData[2];

              stock.setPrice(Double.parseDouble(price));
              stock.setTicker(name);
              stock.setChange(change);
            }

Try something like this:

    //--- Suppose you have input stream `is` of your csv file then:

    BufferedReader reader = new BufferedReader(new InputStreamReader(is));
    try {
        String line;
        while ((line = reader.readLine()) != null) {
             String[] RowData = line.split(",");
             date = RowData[0];
             value = RowData[1];
            // do something with "data" and "value"
        }
    }
    catch (IOException ex) {
        // handle exception
    }
    finally {
        try {
            is.close();
        }
        catch (IOException e) {
            // handle exception
        }
    }

Hope this helps.

For the first part:

HttpClient httpClient = new DefaultHttpClient();
HttpContext localContext = new BasicHttpContext();
HttpGet httpGet = new HttpGet("http://download.finance.yahoo.com/d/quotes.csv?s=msft&f=sl1p2");
HttpResponse response = httpClient.execute(httpGet, localContext);
String result = "";

BufferedReader reader = new BufferedReader(
    new InputStreamReader(
      response.getEntity().getContent()
    )
  );

For the second part, Harry is right, just follow his code, or use some libraries: http://commons.apache.org/sandbox/csv/

CSVReader reader = new CSVReader(** Insert your Reader here **);
    String [] nextLine;
    while ((nextLine = reader.readNext()) != null) {
        // nextLine[] is an array of values from the line
        System.out.println(nextLine[0] + nextLine[1] + "etc...");
    }
