android读取xml步骤

android读取xml方法
项目中经常会用到一些原始的xml文件，那么我们可以定义一些xml供程序使用，xml文件放置在res\xml目录下，通过Resources.getXML()方法访问。

import org.xmlpull.v1.XmlPullParser;
import org.xmlpull.v1.XmlPullParserException;

import android.content.res.Resources;
import android.content.res.XmlResourceParser;

import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class TestXmlActivity extends Activity {

    private TextView myTextView = null;
    private Button myButton = null;

    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.test_xml);

        myTextView = (TextView) findViewById(R.id.xmlContentTextView01);
        myButton = (Button) findViewById(R.id.xmlTestButton1);

        myButton.setOnClickListener(new OnClickListener() {

            public void onClick(View v) {
                int counter = 0;
                StringBuilder sb = new StringBuilder("");
                Resources r = getResources();
                XmlResourceParser xrp = r.getXml(R.xml.test);

                try {
                    // 当没有达到xml的逻辑结束终点
                    // getEventType方法返回读取xml当前的事件
                    while (xrp.getEventType() != XmlResourceParser.END_DOCUMENT) {
                        if (xrp.getEventType() == XmlResourceParser.START_TAG) {
                            String name = xrp.getName();
                            System.out.println(name);
                            if (name.equals("customer")) // 查找符合条件的
                            {
                                counter++; // 统计第几个节点
                                sb.append("第" + counter + "条客户信息：" + "\n");
                                sb.append(xrp.getAttributeValue(0) + "\n");

                                sb.append(xrp.getAttributeValue(3) + "\n");

                            }
                        }// 当读取到xml节点是一个元素的尾标记时
                        else if (xrp.getEventType() == XmlPullParser.END_TAG) {
                            // 控制台输出xml节点结束
                            System.out.println(xrp.getName() + "---End！");
                        } // 当读取到xml节点是文本时
                        else if (xrp.getEventType() == XmlPullParser.TEXT) {
                            // 输出文本
                            sb.append("姓名：" + xrp.getText() + "\n\n");
                        }
                        xrp.next();
                    }
                    myTextView.setText(sb.toString());
                } catch (XmlPullParserException e) {
                    e.printStackTrace();
                } catch (IOException e) {
                    e.printStackTrace();
