Tag that references current theme in xml causes force close

I'm in the middle of implementing themes for my application right now, and everything's been going really smooth until as of late. I've been using the android:background="?thin_border" tag to provide a background for linearlayouts with items that I want visually grouped together. The problem I'm running into is when I try to use this tag in an xml with a custom class as one of the elements, and try to add this background tag.

I've got an xml file that looks generally like so:

<?xml version="1.0" encoding="utf-8"?>
<com.atraudes.CustomLayout1 xmlns:android="http://schemas.android.com/apk/res/android"
    android:orientation="horizontal" 
    android:layout_height="wrap_content" 
    android:layout_width="fill_parent"
    android:layout_gravity="fill_vertical">
    <LinearLayout android:orientation="vertical" 
        android:layout_height="fill_parent"
        android:layout_weight="0" 
        android:background="?thin_border" 
        android:layout_width="wrap_content" />
    ...
</com.atraudes.CustomLayout1>

and the custom class has two constructors:

public class CustomLayout1 extends LinearLayout {
    public CustomLayout1(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public CustomLayout1(Context context) {
        super(context);
    }
    ...
}

with some other functions that store values, manipulate the data, etc. The custom layout class is only ever called directly in the xml, and the xml is inflated like so:

LayoutInflater inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
v = (CustomLayout1) inflater.inflate(R.layout.customlayout1, null);

The problem I'm running into is that I'm getting these error messages:

The error seems to be caused by the android:background="?thin_border" tag. If I remove it from the layout, it inflates fine, and the program continues on. As soon as I add it back in, I get these errors and the program stops.

I would be incredibly grateful of any input you might have. Thank you!

After pulling my hair out over this for the past day (and much longer than that in the past), I figured out the problem. I was setting the theme on the activity before setContent(), which was applying the theme for the activity just fine. I finally figured out that running setTheme() on the context as well fixed the problem. The context holds the theme info, which gets passed to the custom view upon inflation. I assumed that setting the theme on the activity was setting it on the context as well :-/

int customTheme = R.style.customTheme;
setTheme(customTheme);
getApplicationContext().setTheme(customTheme);
setContentView(R.layout.mainactivitylayout);

The only other thing I did differently was during inflation:

v = (CustomLayout1) inflater.inflate(R.layout.customlayout1, parent, false);

parent being a parent layout. This was being done in a ListView adapter, so it was right there :-)

should look like this

<?xml version="1.0" encoding="utf-8"?>
<com.atraudes.CustomLayout1 xmlns:android="http://schemas.android.com/apk/res/android"
   android:orientation="horizontal" 
   android:layout_height="wrap_content" 
   android:layout_width="fill_parent"
   android:layout_gravity="fill_vertical">
<LinearLayout android:orientation="vertical" 
    android:layout_height="fill_parent"
    android:layout_weight="0" 
    style="@styles/thin_border"
    android:layout_width="wrap_content" />

and your style should by

<style name="thin_boarder>
 <item name="android:background">@drawable/customstyle_button_editing</item>
</style>
