android - XMLPullparser getEventType 每次都返回 0

Question

我一直在尝试解析 XML 文件，但 getEventType 方法总是返回 0。并且 While 循环一直在执行。

public class FlowerPullParser 

{

public static List<Flower> parseFed(String content) throws XmlPullParserException, IOException
{

    XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
    XmlPullParser parser = factory.newPullParser();

    parser.setInput(new StringReader(content));

    int eventType = parser.getEventType();

    do
    {

        if(eventType == XmlPullParser.START_TAG)
            Log.i("start-tag",parser.getText());


        else if(eventType ==  XmlPullParser.END_TAG)
            Log.i("End-tag",parser.getText());

        else if(eventType ==  XmlPullParser.TEXT)
            Log.i("Text-tag",parser.getText());


    eventType = parser.next();  
    }while(eventType != XmlPullParser.END_DOCUMENT);
    return null;

}
    }

这是我从中获取 XML 的链接

Flowers.xml

XML 正常出现(通过变量内容)，似乎我的代码有一些错误，但我不明白我做错了什么。答案和建议需要

谢谢!

尝试这种方式，希望这能帮助您解决问题。

        XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
        factory.setNamespaceAware(true);
        XmlPullParser xpp = factory.newPullParser();

        xpp.setInput(new StringReader(content.replace("&","&")));
        int eventType = xpp.getEventType();
        while (eventType != XmlPullParser.END_DOCUMENT) {
            if(eventType == XmlPullParser.START_DOCUMENT) {
                System.out.println("Start document");
            } else if(eventType == XmlPullParser.START_TAG) {
                System.out.println("Start tag "+xpp.getName());
            } else if(eventType == XmlPullParser.END_TAG) {
                System.out.println("End tag "+xpp.getName());
            } else if(eventType == XmlPullParser.TEXT) {
                System.out.println("Text "+xpp.getText());
            }
            eventType = xpp.next();
        }
