Android(安卓)xmlpull 方式解析xml文件

1.新建一个xml文件，放在res/xml目录下

1 <?xml version="1.0" encoding="utf-8"?>2 <citys>3     <city count="1400"  name="深圳">广东</city>4     <city count="1500"  name="广州">广东</city>5     <city count="1000"  name="武汉">湖北</city>6 </citys>

2.布局文件代码如下：

 1 <?xml version="1.0" encoding="utf-8"?> 2 <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 3     android:layout_width="fill_parent" 4     android:layout_height="fill_parent" 5     android:orientation="vertical" > 6  7     <Button  8         android:id="@+id/btn" 9         android:layout_width="wrap_content"10         android:layout_height="wrap_content"11         android:text="@string/btnmsg" />12 13     <EditText 14         android:id="@+id/edit"15         android:layout_width="fill_parent"16         android:layout_height="wrap_content" />17 18 </LinearLayout>

3.后台java解析代码如下：

 1 package ymw.main;  2  3 import java.io.IOException;  4  5 import org.xmlpull.v1.XmlPullParserException;  6  7 import ymw.main.R;  8  9 import android.app.Activity; 10 import android.content.res.XmlResourceParser; 11 import android.os.Bundle; 12 import android.view.View; 13 import android.widget.Button; 14 import android.widget.EditText; 15 16 public class XmlResourceParserSampleActivity extends Activity { 17  @Override 18     public void onCreate(Bundle savedInstanceState) { 19         super.onCreate(savedInstanceState); 20  setContentView(R.layout.main); 21         Button btn = (Button) findViewById(R.id.btn); 22         final EditText edit = (EditText) findViewById(R.id.edit); 23         btn.setOnClickListener(new View.OnClickListener() { 24  @Override 25             public void onClick(View v) { 26                 XmlResourceParser xpr = XmlResourceParserSampleActivity.this27                         .getResources().getXml(R.xml.myxml);// 找到xml文件28                 StringBuilder sb = new StringBuilder(); 29                 try { 30                     // 循环解析31                     while (xpr.getEventType() != XmlResourceParser.END_DOCUMENT) { 32                         if (xpr.getEventType() == XmlResourceParser.START_TAG) { 33                             // 获取标签的标签名34                             String name = xpr.getName(); 35                             if (name.equals("city")) { 36                                 sb.append("城市名称：" + xpr.getAttributeValue(1) 37                                         + "\n"); 38                                 sb.append("人口："39                                         + xpr.getAttributeValue(null, "count") 40                                         + "万\n"); 41                                 try { 42                                     sb.append("所属省份：" + xpr.nextText() + "\n\n"); 43                                 } catch (IOException e) { 44  e.printStackTrace(); 45  } 46  } 47  } 48                         try { 49  xpr.next(); 50                         } catch (IOException e) { 51  e.printStackTrace(); 52  } 53  } 54  edit.setText(sb.toString()); 55                 } catch (XmlPullParserException e) { 56  e.printStackTrace(); 57  } 58  } 59  }); 60  } 61 62 }
