I've got a simple ListView and an ArrayAdapter. But when android goes to draw the screen, I get a null pointer exception every time. Here's the stack:

The code is really simple too. The XML:
<LinearLayout 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:background="#0099cc"
tools:context=".FullscreenActivity"
android:orientation="vertical">
<ListView
android:id="@+id/status_view"
android:layout_width="match_parent"
android:layout_height="wrap_content" >
</ListView>
</LinearLayout>
And the code:
String test[] = {"Line 1","Line 2"};
ListView status = (ListView) findViewById(R.id.status_view);
ArrayAdapter<String> statusList = new ArrayAdapter<String>(this,android.R.layout.simple_list_item_1,R.id.status_view,test);
status.setAdapter(statusList);
I've seen tons of examples that do this same thing, and most people are getting this error when they have a string array with some null pointers in it. As you can see, this is not the case here. Anyone else fought with this before?
