在android中获取并解析CSV文件

Question

我正在尝试从http://download.finance.yahoo.com/d/quotes.csv?s=msft&f=sl1p2获取一个csv文件然后解析它以便我可以将价格和价格变成一个对象设置两个属性.有没有办法可以用android库做到这一点？

编辑:这是联合的当前状态(不工作):

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");
              String name = RowData[0];
              String price = RowData[1];
              String change = RowData[2];

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

尝试这样的事情:

    //--- 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
        }
    }

希望这可以帮助.

第一部分:

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()
    )
  );

对于第二部分,Harry是对的,只需按照他的代码,或使用一些库: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...");
    }
