XmlPullParser getAttributeValue returns null

Question

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");

This works. I guess I was just assuming this wanted the same namespace as returned by getAttributeNamespace.

What are supposed to be passing (or not passing, as it seems) to this parameter anyway?

Works just use this in START_TAG case

Daksh Gargas Over a year ago

why do we always pass null in the first parameter(namespace) ?

I think its default value if attribute does not exist.
