Default Deleting An Earthquake Record

I am new to Android and I am working through Chapter 7. Everything is running smoothly; however, I am trying to figure out a way to delete a record from the earthquake database content provider. I know the methods for deleting rows is already written in the earthquakeProvider class, but my problem is I can't figure out how to implement that. I was thinking an onLongClickListener in the main activity that preforms the request.

Here is what I have so far:

(Earthquake.java)
Code:
  earthquakeListView.setOnItemLongClickListener(new OnItemLongClickListener() {

	@Override
	public boolean onItemLongClick(AdapterView _av, View _v, int _index,
			long arg3) {
		 ContentResolver cr = getContentResolver();
		 cr.delete(EarthquakeProvider.CONTENT_URI, selectedQuake, null);

		return false;
	}
	  
  });
This is not working and any help would be much appreciated.
