I am having a silly problem with a OnItemCliskListener for my ListView. It works well when the XML is very simple but after I improve its complexity, the OnItemCliskListener stop working

In other words, I have a ListView with just a TextView. But if I turn my ListView into a more complex list with other TextView, an Icon a CheckBox, the ClickListener stop working.

If I run exactly the same code changing just the XML, the OnItemCliskListener stops working. I would be rather grateful if you could help me

WORKING LIST VIEW:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:orientation="vertical"
    android:layout_height="fill_parent">
    <TextView android:id="@+id/title"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:layout_toLeftOf="@+id/appCheck"
        android:layout_toRightOf="@+id/appIcon"
        android:textAppearance="?android:attr/textAppearanceLarge">
    </TextView>
</RelativeLayout>

NOT WORKING LISTVIEW:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="fill_parent" android:orientation="vertical"
    android:layout_height="fill_parent">
    <ImageView android:src="@drawable/icon" android:id="@+id/appIcon"
        android:layout_width="30px" android:layout_height="40px"></ImageView>
    <CheckBox android:id="@+id/appCheck"
        android:layout_width="wrap_content" android:layout_height="wrap_content"
        android:layout_alignParentRight="true"></CheckBox>
    <TextView android:id="@+id/title"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:layout_toLeftOf="@+id/appCheck"
        android:layout_toRightOf="@+id/appIcon"
        android:textAppearance="?android:attr/textAppearanceLarge">
    </TextView>
    <TextView android:id="@+id/subtitle"
        android:layout_height="wrap_content" android:layout_width="wrap_content"
        android:layout_toLeftOf="@+id/appCheck"
        android:layout_toRightOf="@+id/appIcon" android:layout_below="@+id/title"
        android:textAppearance="?android:attr/textAppearanceSmall">
    </TextView>
</RelativeLayout>

            tabHost = getTabHost();
            tabHost.setOnTabChangedListener(this);

            ListView runningAppList = (ListView) findViewById(R.id.running_app_listview);
            List<String> list3Strings = new ArrayList<String>();
            list3Strings.add("Item 1");

                        int position, long id) {
                    Toast.makeText(MyTabsActivity.this, "EUREKA", Toast.LENGTH_SHORT).show();
                }

                }

I've figured out that when a custom ListView contains focusable elements, onListItemClick won't work (I think it's the expected behaviour). So I've just removed the focus from the custom view and it did the trick. In other words, I added the following commands to my view:

android:focusable="false"
android:focusableInTouchMode="false"

The full explanation is avaiable here: How to fire onListItemClick in Listactivity with buttons in list?
