问题描述
我想从获取csv文件http://download.finance.yahoo.com/d/quotes.csv?s=msft&f=sl1p2 然后解析它,以便我可以得到的价格和价格变成一个对象,设置两个属性。有没有一种方法,我可以做这个与Android库?
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?
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);
}
推荐答案
/ p>
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
}
}
希望这有帮助。
