Android Question

XmlPullAttributes cannot be cast to XmlBlockParser

Custom xml file to view

This is an error produced from the above question

I managed to get the XML file saved into the assets folder, and loaded (and I can even navigate through the different parts of the parser and produce outputs from them) but when I try to pass the

XmlPullParser
to
LayoutInflater
I get the above error. I am not totally sure why it is happening though.

Below is the activity that I am using (the part of it that involves parsing the Xml file) as well as the xml file (called activity_main.sv) and the logcat.

Ignore the file extension of the xml file. I simply renamed it because the IDE was having fits about inclusion. If the xml file is saved in the res/layouts folder it works just fine (I know because I copied it directly out of the res/layouts folder).

public void onCreate(Bundle savedInstanceState){
...
try {
XmlPullParserFactory factory = XmlPullParserFactory.newInstance();
XmlPullParser parser = factory.newPullParser();
InputStream in = getResources().getAssets().open("views/activity_main.sv");
parser.setInput(new InputStreamReader(in));
LayoutInflater inflate = (LayoutInflater) getSystemService(Context.LAYOUT_INFLATER_SERVICE);
// The below line is line 73, the line which is giving me issue
View view = inflate.inflate(parser, null);
setContentView(view);
}catch(Exception e){
e.printStackTrace();
// Consider the below line Log.d("TAG","Well fuck me it didnt work"). AppLog is a custom class I created to help manage logging.
AppLog.log("Well fuck me it didnt work");
}
}


And my basic relativelayout saved as "activity_main.sv"

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
android:layout_height="match_parent" android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
android:paddingBottom="@dimen/activity_vertical_margin" tools:context=".MainActivity">

<TextView android:text="@string/hello_world" android:layout_width="wrap_content"
android:layout_height="wrap_content" />

</RelativeLayout>


And finally the logcat output

EDIT
After adding the factory.setValidating(true) statement. I have a different error now.
