Android :: ListView Item From Custom Adapter Not Selectable

I'm making a custom adapter so that I can display a list of items with icons which looks like the menu that comes up when you long click the home screen. For some reason though the list items are not clickable. The can be navigated to with the D-pad but they cannot be clicked in any way. I thought maybe the problem was with the AlertDialog I was using so I replaced a working adapter I had elsewhere but I have the same issue there. My adapter looks like this:

ArrayList<IconListItem> mItems; LayoutInflater mInflater;
public IconListAdapter(Context context, ArrayList<IconListItem> items) {
mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
mItems = items;
} public IconListAdapter(Context context) {
this(context, new ArrayList<IconListItem>());
} public void add(IconListItem item) { mItems.add(item);
notifyDataSetChanged(); return item;
} public void remove(IconListItem item) { mItems.remove(item); notifyDataSetChanged();
} @Override public int getCount() { return mItems.size();
} @Override public IconListItem getItem(int position) { return mItems.get(position);
} @Override public long getItemId(int position) { return position;
} @Override public View getView(int position, View convertView, ViewGroup parent) { View view;
if(convertView == null){ view = mInflater.inflate(R.layout.two_line_icon_list_item, null);
} else { view = convertView; } IconListItem item = mItems.get(position);

TextView lineOne = (TextView) view.findViewById(R.id.firstLine);
TextView lineTwo = (TextView) view.findViewById(R.id.secondLine);
ImageView iconImage = (ImageView) view.findViewById(R.id.icon);
lineOne.setVisibility(View.VISIBLE); lineTwo.setVisibility(View.VISIBLE);
iconImage.setVisibility(View.VISIBLE); lineOne.setText(item.getText());
if (item.getSubtext() == null) lineTwo.setVisibility(View.GONE);
else lineTwo.setText(item.getSubtext());
if (item.getIcon() == null) iconImage.setVisibility(View.GONE);
else iconImage.setImageDrawable(item.getIcon());
return view; }

And the XML it's inflating:
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="6dip" >
<ImageView android:id="@+id/icon" android:layout_width="wrap_content"
android:layout_height="fill_parent" android:layout_marginRight="6dip" />
<LinearLayout android:orientation="vertical" android:layout_width="wrap_content"
android:layout_weight="1" android:layout_height="fill_parent" >
<TextView android:layout_width="fill_parent" android:layout_height="wrap_content"
android:layout_weight="1"android:gravity="center_vertical"
android:id="@+id/firstLine" android:ellipsize="marquee" android:inputType="text" />
<TextView android:layout_width="wrap_content" android:layout_height="0dip"
android:layout_weight="1" android:ellipsize="marquee"
android:id="@+id/secondLine" android:inputType="text" />
</LinearLayout> </LinearLayout>

When I say they are not clickable, I mean that they items do not highlight in orange when I press them nor does onItemClick ever get called. In my code I have this, a different adapter for another purpose and it works perfectly

this.foos= foos; fa = new FooAdapter(this.foos); fooList.setAdapter(fa);
// View the details for an item when it is selected
fooList.setOnItemClickListener(new OnItemClickListener() {
@Override public void onItemClick(AdapterView<?> arg0, View arg1, int arg2, long arg3) {
Intent i = new Intent(MyActivity.this, MyOtherActivity.class);
i.putExtra("foo", ((fooAdapter)arg0.getAdapter()).getItem(arg2));
i.putExtra("list_position", arg2);
MyActivity.this.startActivityForResult(i, 0);
} } );

But when I swap out the first 3 lines for
IconListAdapter ila = new IconListAdapter(this);
ila.add(0, "Test 1", android.R.drawable.ic_menu_mylocation);
ila.add(0, "Test 2", android.R.drawable.ic_menu_edit);
ila.add(0, "Test 3", android.R.drawable.ic_menu_search);
groupList.setAdapter(ila);
I t stops working.
