Android : Android onItemClickListener does not work (No focusables in code)

This has been driving me crazy over the past several hours... and I feel like it's something obvious...

I've gotten my code down to a simple ListView with a single TextView in it, but still can't seem to make it work (I don't see the toast or log message in the console).

Any help is greatly appreciated! :)

MainActivity.java

public class MainActivity extends ActionBarActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        SparseArray<Data> data = createData();
        ListView listView = (ListView) findViewById(R.id.listView);
        final CustomListAdapter adapter = new CustomListAdapter(this, data);

        listView.setAdapter(adapter);

        listView.setOnItemClickListener(new OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView parent, View view, int position, long id) {
                Log.v("onItemClick", "Clicked");
                Toast.makeText(getApplicationContext(), "Clicked", Toast.LENGTH_SHORT).show();
            }
        });
    }
}

CustomListAdapter.java

public class CustomListAdapter extends BaseAdapter {
    private final SparseArray<Data> data;
    private LayoutInflater inflater;
    private final Activity activity;

    public CustomListAdapter(Activity activity, SparseArray<Data> data) {
        this.activity = activity;
        this.data = data;
        this.inflater = activity.getLayoutInflater();
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        Log.v("getItem", "" + position);
        return data.get(position);
    }

    @Override
    public long getItemId(int position) {
        return 0;
    }

    @Override
    public int getItemViewType(int position) {
        //TODO: Implement Image vs no image views
        return 0;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parentView) {
        if(convertView == null) {
            convertView = inflater.inflate(R.layout.data, null);
        }

        Data data = (Data) getItem(position);

        ((TextView) convertView.findViewById(R.id.dataTitle)).setText(data.getTitle());

        return convertView;
    }

    @Override
    public int getViewTypeCount() {
        // TODO Auto-generated method stub
        return 1;
    }

    @Override
    public boolean isEmpty() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean areAllItemsEnabled() {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean isEnabled(int arg0) {
        // TODO Auto-generated method stub
        return false;
    }

    @Override
    public boolean hasStableIds() {
        // TODO Auto-generated method stub
        return false;
    }
}

NOTE: I do see that the touch even is at least being registered by the device:
