andriod滚轮选择生日 例子源码下载

由于Android项目开源所致，市面上出现了N多安卓软件市场。为了让我们开发的软件有更多的用户使用，我们需要向N多市场发布，软件升级后，我们也必须到安卓市场上进行更新，给我们增加了工作量。因此我们有必要给我们的Android应用增加自动更新的功能。既然实现自动更新，我们首先必须让我们的应用知道是否存在新版本的软件，因此我们可以在自己的网站上放置配置文件，存放软件的版本信息： 2 baidu_xinwen_1.1.0 http://gdown.baidu.com/data/wisegame/f98d235e39e29031/baiduxinwen.apk在这里我使用的是XML文件，方便读取。由于XML文件内容比较少，因此可通过DOM方式进行文件的解析public class ParseXmlService{ public HashMap parseXml(InputStream inStream) throws Exception { HashMap hashMap = new HashMap(); // 实例化一个文档构建器工厂 DocumentBuilderFactory factory = DocumentBuilderFactory.newInstance(); // 通过文档构建器工厂获取一个文档构建器 DocumentBuilder builder = factory.newDocumentBuilder(); // 通过文档通过文档构建器构建一个文档实例 Document document = builder.parse(inStream); //获取XML文件根节点 Element root = document.getDocumentElement(); //获得所有子节点 NodeList childNodes = root.getChildNodes(); for (int j = 0; j < childNodes.getLength(); j ) { //遍历子节点 Node childNode = (Node) childNodes.item(j); if (childNode.getNodeType() == Node.ELEMENT_NODE) { Element childElement = (Element) childNode; //版本号 if ("version".equals(childElement.getNodeName())) { hashMap.put("version",childElement.getFirstChild().getNodeValue()); } //软件名称 else if (("name".equals(childElement.getNodeName()))) { hashMap.put("name",childElement.getFirstChild().getNodeValue()); } //下载地址 else if (("url".equals(childElement.getNodeName()))) { hashMap.put("url",childElement.getFirstChild().getNodeValue()); } } } return hashMap; }}通过parseXml()方法，我们可以获取服务器上应用的版本、文件名以及下载地址。紧接着我们就需要获取到我们手机上应用的版本信息：/** * 获取软件版本号 * * @param context * @return */private int getVersionCode(Context context){ int versionCode = 0; try { // 获取软件版本号， versionCode = context.getPackageManager().getPackageInfo("com.szy.update", 0).versionCode; } catch (NameNotFoundException e) { e.printStackTrace(); } return versionCode;}           通过该方法我们获取到的versionCode对应AndroidManifest.xml下android:versionCode。android:versionCode和android:versionName两个属性分别表示版本号，版本名称。versionCode是整数型，而versionName是字符串。由于versionName是给用户看的，不太容易比较大小，升级检查时，就可以检查versionCode。把获取到的手机上应用版本与服务器端的版本进行比较，应用就可以判断处是否需要更新软件。处理流程
