XmlPullParser getAttributeValue returns null

问题

I have the following XML structure stored in my assets/xml folder:

<?xml version="1.0" encoding="utf-8"?>
<homescreen>
    <homeitem name="Name1"
              subtext="Description1"
              icon="iconresource1" />
    <homeitem name="Name2"
              subtext="Description2"
              icon="iconresource2" />
    <homeitem name="Name3"
              subtext="Description3"
              icon="iconresource3" />
</homescreen>

I'm reading each individual homeitem using an XmlPullParser:

int event;
String TAG_ITEM = "homeitem";
while ((event = parser.next()) != XmlPullParser.END_DOCUMENT) {
    if (event == XmlPullParser.START_TAG) {
        String tag = parser.getName();
        if (TAG_ITEM.equals(tag)) {
            // Works - Logs "Name1"
            Log.d(LOG_NAME, parser.getAttributeValue(0));

            // Works - Logs "name"
            Log.d(LOG_NAME, parser.getAttributeName(0));

            // Works - Logs ""
            Log.d(LOG_NAME, parser.getAttributeNamespace(0));

            // Fails - Logs null
            Log.d(LOG_NAME, parser.getAttributeValue(XmlPullParser.NO_NAMESPACE, "name"));
        }
    }
}

My problem is: using getAttributeValue(String, String) always returns null. Using getAttributeValue(Integer) works fine. What am I doing wrong?

try this :

parser.getAttributeValue(null, "name");
