我有这个 xml:

<?xml version='1.0' encoding='UTF-8' standalone='yes' ?>
  <alllogs count="5">
    <log number="+919876543210" time="1365589432804" date="Wed Apr 10 15:53:52 GMT+05:30 2013" type="2" duration="0" new="1" name="360 chhotein" numbertype="2" numberlabel="null" />
    <log number="+919876543210" time="1365595887261" date="Wed Apr 10 17:41:27 GMT+05:30 2013" type="2" duration="0" new="1" name="360 chhotein" numbertype="2" numberlabel="null" />
    <log number="+919876543210" time="1365596387590" date="Wed Apr 10 17:49:47 GMT+05:30 2013" type="2" duration="0" new="1" name="360 chhotein" numbertype="2" numberlabel="null" />
    <log number="+919876543210" time="1365596787051" date="Wed Apr 10 17:56:27 GMT+05:30 2013" type="2" duration="0" new="1" name="null" numbertype="null" numberlabel="null" />
    <log number="0041786095382" time="1365740469738" date="Fri Apr 12 09:51:09 GMT+05:30 2013" type="2" duration="0" new="1" name="null" numbertype="null" numberlabel="null" />
  </alllogs>

我使用的解析器是android原生的XMLPullParser

我无法更改 XML 格式，但如果值得，我可以使用另一个 android 兼容的解析器。

如果不清楚它必须适合这样的类:

try {
        String file = Environment.getExternalStorageDirectory() + File.separator + "SmsContactsBackup/logs/calllogs_20130412125502.xml";
         XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
         factory.setNamespaceAware(true);
         XmlPullParser parser = factory.newPullParser();
         FileInputStream fis = new FileInputStream(file);
         parser.setInput(new InputStreamReader(fis));
         Log.d("Response", ""+convertStreamToString(fis));
         int eventType = parser.getEventType();
         String name = null;
         while (eventType != XmlPullParser.END_DOCUMENT)
         {
             //String name = parser.getName();

             if(eventType == XmlPullParser.START_DOCUMENT) {
                 System.out.println("Start document");
             }else if(eventType == XmlPullParser.START_TAG) {
                 name = parser.getName();
                 if (name.equalsIgnoreCase("alllogs")){
                     count = Integer.parseInt(parser.getAttributeValue("", "count"));
                }else if(name.equalsIgnoreCase("log"))
                {
                    phone_no.add(parser.getAttributeValue("", "number"));
                }
                 System.out.println("Start tag "+parser.getName());
             }else if(eventType == XmlPullParser.END_TAG) {
                 name = parser.getName();
                 System.out.println("End tag "+parser.getName());
             }
             eventType = parser.next();
         }
    } catch (FileNotFoundException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (XmlPullParserException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (IOException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } catch (Exception e) {
        // TODO Auto-generated catch block
        e.printStackTrace();
    } 

事件类型不正确和 IOException。

最佳答案

最后我得到了这样的解决方案我使用了 Dom 解析

public class MainActivity extends Activity {

    ArrayList<String> mImageLink;
    ArrayList<String> phone_no;
    int count;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
         mImageLink = new ArrayList<String>();
         phone_no = new ArrayList<String>();

         try {
         File file = new File("mnt/sdcard/Backup_Apps/call_logs/calllog_35777569.xml");
         InputStream is = new FileInputStream(file.getPath());
         DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
         DocumentBuilder db = dbf.newDocumentBuilder();
         Document doc = db.parse(new InputSource(is));
         doc.getDocumentElement().normalize();

         NodeList nodeList = doc.getElementsByTagName("alllogs");

         for (int i = 0; i < nodeList.getLength(); i++) {

             Node node = nodeList.item(i);

             Element fstElmnt = (Element) node;

             mImageLink.add(fstElmnt.getAttribute("count"));
             count = Integer.parseInt(mImageLink.get(i));

         }
         NodeList n = doc.getElementsByTagName("log");

         for (int j = 0; j < count; j++) {
             Node node = n.item(j);

             Element fstElmnt = (Element) node;

             phone_no.add(fstElmnt.getAttribute("number"));

        }
     } catch (Exception e) {
         System.out.println("XML Pasing Excpetion = " + e);
     }
 }
}
