La vista de lista personalizada no responde al evento de clic

Como puede imaginar, todo se carga bien, no se activa ningún evento de clic. Antes de comenzar, he leído tantos hilos sobre esto, sin embargo, por mi vida no puedo entenderlo. Aquí está el código.

activity_main.xml (Diseño principal para llamar a la lista)

<LinearLayout
    android:orientation="vertical" 
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">

     <ListView
         android:id="@android:id/list"
         android:layout_width="fill_parent"
         android:layout_height="fill_parent"

         />

</LinearLayout>

list_mainsegments_row.xml (fila personalizada)

    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:clickable="true"
        android:orientation="horizontal" 
        >

        <ImageView
            android:id="@+id/iconView"
            style="@style/generalPagesLogoStyle"
            android:layout_width="50dp"
            android:layout_height="50dp"
            android:layout_margin="@dimen/tendpPadding"
            android:scaleType="fitCenter"
            android:src="@drawable/ic_launcher" />

        <TextView
            android:id="@+id/titleMainSegments"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="left|center_vertical"
            android:layout_weight="0.5"
            android:text="Medium Text"
            android:textAppearance="?android:attr/textAppearanceMedium"
            android:textSize="@dimen/generalTextSize"
             />

        <ImageButton
            android:id="@+id/imageButton1"
            android:layout_width="30dp"
            android:layout_height="30dp"
            android:layout_gravity="center_vertical"
            android:scaleType="fitCenter"
            android:src="@drawable/arrow" />
    </LinearLayout>

MyAdapter.java

   public class MyAdapter extends ArrayAdapter<String> {

    public MyAdapter(Context context, int resource, int textViewResourceId,
            String[] strings) {
        super(context, resource, textViewResourceId, strings);
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        LayoutInflater inflater = LayoutInflater.from(getContext());
        // This is a single row
        View row = inflater.inflate(R.layout.list_mainsegments_row, parent,
                false);
        String[] items = getContext().getResources().getStringArray(
                R.array.segments_main);
        ImageView iv = (ImageView) row.findViewById(R.id.iconView);
        TextView tv = (TextView) row.findViewById(R.id.titleMainSegments);
        tv.setText(items[position]);
        organiseLayout(position, items, iv);
        return row;

    }

    private void organiseLayout(int position, String[] items, ImageView iv) {
        if (items[position].equals(getContext().getResources().getString(
                R.string.segment_one))) {
            iv.setImageResource(R.drawable.img1);
        }
        if (items[position].equals(getContext().getResources().getString(
                R.string.segment_two))) {
            iv.setImageResource(R.drawable.img2);
        }
    }
}

MainActivity.java

public class MainActivity extends ListActivity implements OnItemClickListener {

private MyAdapter mAdapter;

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

    mAdapter = new MyAdapter(this, android.R.layout.simple_list_item_1,
            R.id.titleMainSegments, getResources().getStringArray(
                    R.array.segments_main));

    setListAdapter(mAdapter);
    getListView().setOnItemClickListener(this);

}

public void onItemClick(AdapterView<?> parent, View view,
        int position, long id) {
    CharSequence text = "Item clicked";
    int duration = Toast.LENGTH_SHORT;
    Toast toast = Toast.makeText(this, text, duration);
    toast.setGravity(Gravity.CENTER_HORIZONTAL | Gravity.CENTER_VERTICAL,
            duration, duration);
    toast.show();
} }

No hay ningún error, por lo que el registro logCat no será útil. Todo sale bien, pero no se muestra Toast cuando se toca ListView.
