Why does my program crash after I add Listview? Android

I am attempting to connect a listview lv to its id using

        ListView lv = (ListView) findViewById(R.id.ImTrackingListView);

However whenever it hits this step my program crashes and sends it to the Source not found page. Here is my code

public class ImTracking extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.imtrackinglayout);
        ListView lv = (ListView) findViewById(R.id.imtrackinglistview);

I checked to make sure that there wasn't another id with the same name. Hopefully someone can help me find out why this is happening.

edit here is the xml (I changed the id to lowercase)

 <?xml version="1.0" encoding="utf-8"?>
 <LinearLayout
   xmlns:android="http://schemas.android.com/apk/res/android"
  android:orientation="vertical"
  android:layout_width="fill_parent"
  android:layout_height="fill_parent">


 <ListView   android:layout_width="fill_parent"
android:layout_height="fill_parent" android:id="@+id/imtrackinglistview"></ListView>

 </LinearLayout>

Here is my logcat response

Try cleaning your project, for some reason the error contains a TextView.

There is a class cast exception in ImTracking file , post the error from log cat.Select E - and the last exception thrown would be in red , paste that.
