Android XML解析listview

别裁伪体亲风雅，转益多师是汝师。这篇文章主要讲述Android XML解析listview相关的知识，希望能为你提供帮助。
我使用本教程http://www.androidbegin.com/tutorial/android-xml-parse-images-and-texts-tutorial/来实现XML解析，如果我想将url更改为这个http://gis.taiwan.net.tw/XMLReleaseALL_public/activity_C_f.xml，该怎么做？因为xml格式不同。如果有类似的问题请通知我。谢谢。
每个listitem都有一个标签，但我的网址只包含所有标签的'Infos'。

答案更改getXmlFromUrl()中的URL，然后更改parser.getValue(e, **RANK**)中的键。无论您的格式是什么，您都需要指定获取数据的密钥，然后相应地保存。
另一答案在该教程中，作者正在从XML的TEXT标记中读取值。但在您的情况下，您需要从属性名称获取值。

private void parseRequestResultXML(InputStream stream) {arraylist=new ArrayList< HashMap< String,String> > (); try { XmlPullParserFactory factory = XmlPullParserFactory.newInstance(); XmlPullParser parser = factory.newPullParser(); parser.setInput(stream, null); HashMap< String, String> map = null; int eventType = parser.getEventType(); while (eventType != XmlPullParser.END_DOCUMENT) { switch (parser.getEventType()) {case XmlPullParser.START_DOCUMENT: //Log.i("TAG", " Start document " + parser.getName()); break; case XmlPullParser.START_TAG: //Log.i("TAG", " Start tag " + parser.getName()); String tag=parser.getName(); if(tag.equals("Info")){ //read values from Info tag Log.i("TAG","reading info"); String id=parser.getAttributeValue(null, "Id"); String name=parser.getAttributeValue(null, "Name"); String website=parser.getAttributeValue(null, "Website"); //do same for other valuesmap = new HashMap< String, String> (); map.put("id", id); map.put("name", name); map.put("website", website); arraylist.add(map); }break; case XmlPullParser.END_TAG: //Log.i("TAG", " End tag " + parser.getName()); break; default: break; } eventType=parser.next(); //get next event type }//reading all values from list for (Map< String,String> e : arraylist) { Log.d("TAG"," Row ID "+e.get("id")+" Name "+e.get("name")+" Website "+e.get("website")); }} catch (XmlPullParserException e) { e.printStackTrace(); } catch (IOException e1) { e1.printStackTrace(); } }

更新：在XMLParser.java中添加此方法

public InputStream getInputStreamFromUrl(String url) { String xml = null; try { DefaultHttpClient httpClient = new DefaultHttpClient(); HttpPost httpPost = new HttpPost(url); HttpResponse httpResponse = httpClient.execute(httpPost); HttpEntity httpEntity = httpResponse.getEntity(); return httpEntity.getContent(); } catch (UnsupportedEncodingException e) { e.printStackTrace(); } catch (ClientProtocolException e) { e.printStackTrace(); } catch (IOException e) { e.printStackTrace(); } return null; }

在doInBackground

arraylist = new ArrayList< HashMap< String, String> > (); XMLParser parser = new XMLParser(); // Retrieve nodes from the given URL address InputStream stream = parser.getInputStreamFromUrl("http://www.androidbegin.com/tutorial/xmlparseimgtxt.xml"); if (stream != null){ parseRequestResultXML(stream); stream.close(); }
