How can we create a XMLWriter?The writer when passed to the parser will write the XML to the specified outputStream. Is there any direct class in android to acheive this? Thanks in advance.

推荐答案

使用 XmlSerializer的实现你的目标。
你可以得到一些想法创建XML <一个href=\"http://www.ibm.com/developerworks/opensource/library/x-android/index.html#list11\">here.

示例

private String writeXml(List<Message> messages){
    XmlSerializer serializer = Xml.newSerializer();
    StringWriter writer = new StringWriter();
    try {
        serializer.setOutput(writer);
        serializer.startDocument("UTF-8", true);
        serializer.startTag("", "messages");
        serializer.attribute("", "number", String.valueOf(messages.size()));
        for (Message msg: messages){
            serializer.startTag("", "message");
            serializer.attribute("", "date", msg.getDate());
            serializer.startTag("", "title");
            serializer.text(msg.getTitle());
            serializer.endTag("", "title");
            serializer.startTag("", "url");
            serializer.text(msg.getLink().toExternalForm());
            serializer.endTag("", "url");
            serializer.startTag("", "body");
            serializer.text(msg.getDescription());
            serializer.endTag("", "body");
            serializer.endTag("", "message");
        }
        serializer.endTag("", "messages");
        serializer.endDocument();
        return writer.toString();
    } catch (Exception e) {
        throw new RuntimeException(e);
    } 
}
