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)
                                        + "
");
                                sb.append("人口："
                                        + xpr.getAttributeValue(null, "count")
                                        + "万
");
                                try {
                                    sb.append("所属省份：" + xpr.nextText() + "

");
                                } catch (IOException e) {
                                    e.printStackTrace();
                                }
                            }
                        }
                        try {
                            xpr.next();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                    }
                    edit.setText(sb.toString());
                } catch (XmlPullParserException e) {
                    e.printStackTrace();
                }
            }
        });
    }

}
