I cannot read the AttributeSet from my XML resources

Question

I'm trying to read an AttributeSet from an XML resource file. The relevant code is the following:

//This happens inside an Activity
        Resources r = getResources();
        XmlResourceParser parser = r.getXml(R.layout.testcameraoverlay);
        AttributeSet as = Xml.asAttributeSet(parser);

        int count = as.getAttributeCount(); //count is 0!!??

count == 0, so Android is not reading any attributes at all!

The XML file(R.layout.testcameraoverlay):

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:text="@string/app_name" android:id="@+id/TextView01" android:layout_width="wrap_content" android:layout_height="wrap_content">
</TextView>

Why can't I read the attributes?

Answer 1

The problem was a misunderstanding of the functioning of the parser. After the line:

XmlResourceParser parser = r.getXml(R.layout.testcameraoverlay);

the parser is at the beginning of the document and hasn't yet read any element, therefore there is no attributeset because the attributes are of course always relative to the current element. So to fix this I had to do the following which is iterating over the elements until I get to "TextView":

    AttributeSet as = null;
    Resources r = getResources();
    XmlResourceParser parser = r.getLayout(R.layout.testcameraoverlay);

    int state = 0;
    do {
        try {
            state = parser.next();
        } catch (XmlPullParserException e1) {
            e1.printStackTrace();
        } catch (IOException e1) {
            e1.printStackTrace();
        }       
        if (state == XmlPullParser.START_TAG) {
            if (parser.getName().equals("TextView")) {
                as = Xml.asAttributeSet(parser);
                break;
            }
        }
    } while(state != XmlPullParser.END_DOCUMENT);
