Android xmlpull 方式解析xml文件

1.新建一个xml文件，放在res/xml目录下

 <?xml version="1.0" encoding="utf-8"?>
 <citys>
     <city count="1400"  name="深圳">广东</city>
     <city count="1500"  name="广州">广东</city>
     <city count="1000"  name="武汉">湖北</city>
 </citys>

2.布局文件代码如下：

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
     android:layout_width="fill_parent"
     android:layout_height="fill_parent"
     android:orientation="vertical" >
 
     <Button
         android:id="@+id/btn"
         android:layout_width="wrap_content"
         android:layout_height="wrap_content"
         android:text="@string/btnmsg" />
 
     <EditText
         android:id="@+id/edit"
         android:layout_width="fill_parent"
         android:layout_height="wrap_content" />
 
 </LinearLayout>

3.后台java解析代码如下：

 package ymw.main;
 
 import java.io.IOException;
 
 import org.xmlpull.v1.XmlPullParserException;
 
 import ymw.main.R;
 
 import android.app.Activity;
 import android.content.res.XmlResourceParser;
 import android.os.Bundle;
 import android.view.View;
 import android.widget.Button;
 import android.widget.EditText;
 
 public class XmlResourceParserSampleActivity extends Activity {
     @Override
     public void onCreate(Bundle savedInstanceState) {
         super.onCreate(savedInstanceState);
         setContentView(R.layout.main);
         Button btn = (Button) findViewById(R.id.btn);
         final EditText edit = (EditText) findViewById(R.id.edit);
         btn.setOnClickListener(new View.OnClickListener() {
             @Override
             public void onClick(View v) {
                 XmlResourceParser xpr = XmlResourceParserSampleActivity.this
                         .getResources().getXml(R.xml.myxml);// 找到xml文件
                 StringBuilder sb = new StringBuilder();
                 try {
                     // 循环解析
                     while (xpr.getEventType() != XmlResourceParser.END_DOCUMENT) {
                         if (xpr.getEventType() == XmlResourceParser.START_TAG) {
                             // 获取标签的标签名
                             String name = xpr.getName();
                             if (name.equals("city")) {
                                 sb.append("城市名称：" + xpr.getAttributeValue(1)
                                         + "\n");
                                 sb.append("人口："
                                         + xpr.getAttributeValue(null, "count")
                                         + "万\n");
                                 try {
                                     sb.append("所属省份：" + xpr.nextText() + "\n\n");
                                 } catch (IOException e) {
                                     e.printStackTrace();
                                 }
                             }
                         }
                         try {
                             xpr.next();
                         } catch (IOException e) {
                             e.printStackTrace();
                         }
                     }
                     edit.setText(sb.toString());
                 } catch (XmlPullParserException e) {
                     e.printStackTrace();
                 }
             }
         });
     }
