Android xmlpull 方式解析xml檔案

標籤：

1.建立一個xml檔案，放在res/xml目錄下

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

2.布局檔案代碼如下：

 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     <EditText14         android:id="@+id/edit"15         android:layout_width="fill_parent"16         android:layout_height="wrap_content" />17 18 </LinearLayout>

3.後台java解析代碼如下：

 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     @Override18     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             @Override25             public void onClick(View v) {26                 XmlResourceParser xpr = XmlResourceParserSampleActivity.this27                         .getResources().getXml(R.xml.myxml);// 找到xml檔案28                 StringBuilder sb = new StringBuilder();29                 try {30                     // 迴圈解析31                     while (xpr.getEventType() != XmlResourceParser.END_DOCUMENT) {32                         if (xpr.getEventType() == XmlResourceParser.START_TAG) {33                             // 擷取標籤的標籤名34                             String name = xpr.getName();35                             if (name.equals("city")) {36                                 sb.append("城市名稱：" + xpr.getAttributeValue(1)37                                         + "\n");38                                 sb.append("人口："39                                         + xpr.getAttributeValue(null, "count")40                                         + "萬\n");41                                 try {42                                     sb.append("所屬省份：" + 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 }
