Android XML解析列表视图

我使用本教程来实现XML解析，如果我想将url更改为这一个，如何做到这一点？因为xml格式不同。如果有类似的问题，请通知我。谢谢

每个listitem中都有一个标记，但我的url在开始时只包含“Infos”，其中包括所有标记

更改

getXmlFromUrl（）

中的URL，然后更改

parser.getValue（e，**RANK**）

中的键。无论您的格式是什么，都需要指定获取数据的键，然后进行相应的保存

标记中读取值。但在您的情况下，需要从属性名中获取值

private void parseRequestResultXML(InputStream stream) {

        arraylist=new ArrayList<HashMap<String,String>>();

        try {

            while (eventType != XmlPullParser.END_DOCUMENT) {

                        String name=parser.getAttributeValue(null, "Name");
                        String website=parser.getAttributeValue(null, "Website");

    }

在
doInBackground

arraylist = new ArrayList<HashMap<String, String>>();
XMLParser parser = new XMLParser();
// Retrieve nodes from the given URL address
InputStream stream = parser.getInputStreamFromUrl("http://www.androidbegin.com/tutorial/xmlparseimgtxt.xml");
if (stream != null){
    parseRequestResultXML(stream);
    stream.close();
}

arraylist=newarraylist（）；
XMLParser=新的XMLParser（）；
//从给定的URL地址检索节点
InputStream=解析器。getInputStreamFromUrl（“http://www.androidbegin.com/tutorial/xmlparseimgtxt.xml");
if（流！=null）{
parseRequestResultXML（流）；
stream.close（）；
}
为什么要负面评论？为什么不留下评论？更改getXmlFromUrl中的URL？没有注意到标记格式不同吗？谢谢。但我不知道应该从代码中替换哪一行。只需调用方法，并将inputstream作为参数。stream.close（）；在句柄异常上说我应该将私有void parseRequestResultXML放在哪里？在DownloadXML中。。。about stream.close（）捕获异常。把它放在try块中。不起作用，begin标记是dude，你需要更改键来获取数据。如果新标记是info，那么您可以像这样检查它，如果（tag.equals（“info”））。所有内容都是用代码编写的。
