需要解析的xml内容：

http封装类：

package com.tudou.activity.work3;
    
    import java.io.IOException;
    import java.io.InputStream;
    import java.net.HttpURLConnection;
    import java.net.URL;
    
    import android.util.Log;
    
    public class HttpUtil {
    	public static InputStream getInputStream(String path) {
    		try {
    			URL url = new URL(path);
    			HttpURLConnection conn = (HttpURLConnection) url.openConnection();
    			conn.setDoInput(true);
    			conn.setReadTimeout(3000);
    			conn.setConnectTimeout(3000);
    			conn.setRequestMethod("POST");
    			if (conn.getResponseCode() == 200) {
    				Log.d("mylog", "getResponseCode:" + 200);
    				return conn.getInputStream();
    			}
    		} catch (IOException e) {
    			e.printStackTrace();
    		}
    		return null;
    	}
    }

使用xmlpull解析xml，直接用json封装：

package com.tudou.activity.work3;
    
    import java.io.IOException;
    import java.io.InputStream;
    import java.util.List;
    
    import org.json.JSONException;
    import org.json.JSONObject;
    import org.xmlpull.v1.XmlPullParser;
    import org.xmlpull.v1.XmlPullParserException;
    import org.xmlpull.v1.XmlPullParserFactory;
    
    import android.util.Log;
    
    public class XmlParser {
    	public static String getXML(InputStream inputStream, String inputEncoding) {
    		JSONObject obj = new JSONObject();
    		try {
    			// Log.d("mylog", "XmlParser" + 200);
    			XmlPullParser parser = XmlPullParserFactory.newInstance()
    					.newPullParser();
    			parser.setInput(inputStream, inputEncoding);
    			int eventType = parser.getEventType();
    			JSONObject obj2 = new JSONObject();
    			JSONObject obj3 = new JSONObject();
    			JSONObject obj4 = new JSONObject();
    			while (eventType != XmlPullParser.END_DOCUMENT) {
    				// Log.d("mylog", "eventType:" + eventType);
    				switch (eventType) {
    				case XmlPullParser.START_DOCUMENT:
    					break;
    				case XmlPullParser.START_TAG:
    					Log.d("mylog", "name:" + parser.getName());
    					if ("uploadPhoto".equals(parser.getName())) {
    						obj2.put(parser.getName(), parser.nextText());
    					} else if ("specifyFriends".equals(parser.getName())) {
    						obj2.put(parser.getName(), parser.nextText());
    					} else if ("sharWx".equals(parser.getName())) {
    						obj2.put(parser.getName(), parser.nextText());
    					} else if ("emoji".equals(parser.getName())) {
    						obj2.put(parser.getName(), parser.nextText());
    					} else if ("score".equals(parser.getName())) {
    						obj2.put(parser.getName(), parser.nextText());
    					} else if ("photo".equals(parser.getName())) {
    						obj3.put(parser.getName(), parser.nextText());
    					} else if ("supplementaryQuestion".equals(parser.getName())) {
    						obj3.put(parser.getName(), parser.nextText());
    					} else if ("collect".equals(parser.getName())) {
    						obj3.put(parser.getName(), parser.nextText());
    					} else if ("elective".equals(parser.getName())) {
    						obj4.put(parser.getName(), parser.nextText());
    					}
    					break;
    				case XmlPullParser.END_TAG:
    					if ("app".equals(parser.getName())) {
    						obj.put("dynamic", obj2);
    						obj.put("doubt", obj3);
    						obj.put("courses", obj4);
    					}
    					break;
    				default:
    					break;
    				}
    				eventType = parser.next();
    			}
    		} catch (XmlPullParserException e) {
    			e.printStackTrace();
    		} catch (IOException e) {
    			e.printStackTrace();
    		} catch (JSONException e) {
    			e.printStackTrace();
    		} finally {
    			try {
    				inputStream.close();
    			} catch (IOException e) {
    				e.printStackTrace();
    			}
    		}
    		return obj.toString();
    	}
    }

activity，此处练手不考虑效率，直接放在主线程中了：

package com.tudou.activity.work3;
    
    import com.tudou.activity.R;
    
    import android.app.Activity;
    import android.os.Bundle;
    import android.util.Log;
    
    public class HomeWork3 extends Activity {
    	String path = "http://software.webtrn.cn/cms/res_base/software_webtrn_cn/privacy/config/tyxl/appConfiguration.xml";
    
    	@Override
    	protected void onCreate(Bundle savedInstanceState) {
    		super.onCreate(savedInstanceState);
    		setContentView(R.layout.homework3);
    	}
    	
    	@Override
    	protected void onStart() {
    		super.onStart();
    		String result = XmlParser.getXML(HttpUtil.getInputStream(path), "utf-8");
    		Log.d("mylog", "result:" + result);
    	}
    }

顺便贴一个练手的界面。
