Android XmlPullParser 解析xml

Android 解析Xml 的方式有多种,SAX、DOM、Pull 都可以实现,这里使用的是其中的一种.
下面的代码主要是在IntentService 里面解析一个xml 白名单的.主要是记录一下,时间长了容易忘记.

public class NameListServices extends IntentService {
	private final static String TAG = "NameListServices";

	private List infos = new ArrayList();
	public NameListServices() {
		super("NameListServices");
	}

	@Override
	protected void onHandleIntent(Intent intent) {
		Log.i(TAG, "onHandleIntent");
		if(intent != null) {
			String uri = intent.getStringExtra("uri");
			InputStream is = null;
			if(uri != null) {
				try {
					is = getContentResolver().openInputStream(Uri.fromFile(new File(uri)));
					readXml(is);
					//updateInfoToDB();
				} catch (FileNotFoundException e) {
					e.printStackTrace();
					if(is != null) {
						try {
							is.close();
						} catch (IOException e1) {
							e1.printStackTrace();
						}
					}
				}
			}
		}
	}

	private void readXml(InputStream is) {
		Log.i(TAG, "readXml");
		try {
			XmlPullParser parser = Xml.newPullParser();
			parser.setInput(is, "UTF-8");
			int eventType = parser.getEventType();

			AppInfo appInfo ;
			while(eventType != XmlPullParser.END_DOCUMENT) {
				switch (eventType) {
				case XmlPullParser.START_DOCUMENT:
					break;
				case XmlPullParser.START_TAG:
					String name = parser.getName();
					if(name != null && name.trim().equals("AppInfo")) {
						String pkg = parser.getAttributeValue(null,"pkg");
						String type = parser.getAttributeValue(null,"type");
						appInfo = new AppInfo(pkg, type);
						Log.i(TAG, "appInfo:" + appInfo);
						infos.add(appInfo);
					}
					break;
				case XmlPullParser.END_TAG:
					break;

				default:
					break;
				}
				eventType = parser.next();
			}
		}catch (XmlPullParserException e) {
			e.printStackTrace();
		} catch (IOException e) {
			e.printStackTrace();
		}finally {
			if(is != null) {
				try {
					is.close();
				} catch (IOException e) {
					e.printStackTrace();
				}
			}
		}
	}
