adding CheckBox to list row loses my onItemClick events?

I have a ListView with an ArrayList adapter. The rows are not very complex (an Image on the left, a LinearLayout with TextViews inside, and a CheckBox on the right ... the layout is copied in below.) The goal is to have a QuickAction bar come up if the user clicks on the image or text, and have the CheckBox change state if the user clicks on the CheckBox. I have each part working independently, but not when they're together in the layout - somehow, I'm losing the onItemClick event.

The "QuickAction" bar is activated by OnItemClickListener(), and it works fine - unless I have the CheckBox in the layout, in which case the CheckBox works fine (using onClick()) but the onItemClickListener is never fired if the user clicks in the row but outside the CheckBox. The layout (minus some style stuff) is:

<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/vw1"
    android:layout_width="fill_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <ImageView android:id="@+id/img"
        android:layout_alignParentLeft="true"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"/>

    <CheckBox android:id="@+id/ckb"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentRight="true"
    android:layout_gravity="right"
    android:checked="false" />

<!-- stack text in middle section of the row -->
    <LinearLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <TextView android:id="@+id/text1"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content""/>

        <TextView android:id="@+id/text2"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"/>
    </
