java - Android中从URL读取XML文件

Question

我尝试了多种从链接打开 XML 文件的方法，但所有方法都没有任何效果。为了确保解析 XML 文件的效果良好，我下载了该文件并将其放入 Asset 文件夹中，以便解析所有这些内容。由此我们可以推断出读取url时出现的错误

网址为http://feeds.bbci.co.uk/sport/0/football/rss.xml?edition=uk

HttpClient httpclient = new DefaultHttpClient();
HttpGet httppost = new HttpGet(url.toString());
HttpResponse response = httpclient.execute(httppost);
InputStream in=response.getEntity().getContent();

或者

HttpURLConnection con=(HttpURLConnection)url.openConnection();
InputStream in=con.getInputStream();

或者

InputStream in =url.openStream();

请帮帮我

我的问题已经解决，感谢大家的帮助。当我从 Url 获取文件时，我应该使用 AsyncTask 类

public void xmlReader() {

        try {

            URL url = new URL("http://feeds.bbci.co.uk/sport/0/football/rss.xml");

            DocumentBuilderFactory documentBuilderFactory = DocumentBuilderFactory
                    .newInstance();
            DocumentBuilder documentBuilder = documentBuilderFactory
                    .newDocumentBuilder();
            Document document = documentBuilder.parse(new InputSource(url
                    .openStream()));

            nodlist = document.getElementsByTagName("Youritem");

            for (int i = 0; i < nodlist.getLength(); i++) {
                Element element = (Element) nodlist.item(i);

                NodeList nodlistid = element.getElementsByTagName("Id");
                Element id = (Element) nodlistid.item(0);


                NodeList nodlistBaslik = element.getElementsByTagName("tagname1");
                Element baslik = (Element) nodlistBaslik.item(0);

                NodeList nodlistDetay = element.getElementsByTagName("tagname2");
                Element detay = (Element) nodlistDetay.item(0);

                NodeList nodlistKaynak = element.getElementsByTagName("tagname3");
                Element lat = (Element) nodlistKaynak.item(0);

                NodeList nodelistMedia = element.getElementsByTagName("tagname4");
                Element longi = (Element) nodelistMedia.item(0);

                NodeList nodelistTur = element.getElementsByTagName("tagname5");
                Element tur = (Element) nodelistTur.item(0);
                // String resimURL =
                // resim.getAttributes().getNamedItem("url").getNodeValue();

                NodeList nodelistMedia1 = element.getElementsByTagName("enclosure");    
                Element picture= (Element) nodelistMedia1.item(0);
                String pictureURL = resim.getAttributes().getNamedItem("picturetagname").getNodeValue();    

                xmltagname1.add(tagname1.getChildNodes().item(0).getNodeValue());
                xmltagname2.add(tagname2.getChildNodes().item(0).getNodeValue());
                xmltagname3.add(tagname3.getChildNodes().item(0).getNodeValue());
                xmltagname4.add(tagname4.getChildNodes().item(0).getNodeValue());
                xmltagname5.add(tagname5.getChildNodes().item(0).getNodeValue());


            }

        } catch (Exception e) {
            e.printStackTrace();
        }

    }

我认为这个方法可以帮助你..放轻松
