我在Android上使用XmlPullParser但get getText返回null。 为什么会这样?
代码,注释行给出null
ArrayList<String> titleList = new ArrayList<String>();
try {
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
factory.setNamespaceAware(true);
XmlPullParser xpp = factory.newPullParser();
xpp.setInput(this.getInputStream(), null);
int eventType = xpp.getEventType();
while (eventType != XmlPullParser.END_DOCUMENT) {
if (eventType == XmlPullParser.START_TAG) {
if (xpp.getName().equalsIgnoreCase(TITLE)) {
// MainActivity.itemsList.add(xpp.getText());
Log.d("XGamers", "a");
}
}``
eventType = xpp.next();
}
} catch (XmlPullParserException e) {
Log.e("XGamers", "XmlPullParserException in FeedParser");
} catch (IOException e) {
Log.e("XGamers", "IOException in FeedParser");
}
答案 0 :(得分:9)
试试这个:
if (xpp.getName().equalsIgnoreCase(TITLE)) {
if(xpp.next() == XmlPullParser.TEXT) {
MainActivity.itemsList.add(xpp.getText());
Log.d("XGamers", "a");
}
}
另外,请确保您的itemsList已初始化。
