Estoy tratando de agregar una vista de clic simple a un elemento de una vista de reciclador, pero por alguna razón tengo que hacer clic en un elemento dos veces en lugar de una para realizar una acción. Con un solo clic, parece que la vista del reciclador no detecta un clic. En el siguiente, sin embargo, detecta el clic y realiza una acción adecuada.

XML:

<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/cardView"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    >

    <RelativeLayout
        android:id="@+id/rlContainer"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:clickable="true"
        android:focusable="true"
        android:focusableInTouchMode="true"
        android:background="@drawable/selector_inventory_recycler_item"
        android:padding="16dp">

        <ImageView
            android:id="@+id/item_photo"
            android:layout_width="100dp"
            android:layout_height="100dp"

            android:layout_alignParentTop="true"
            android:layout_marginRight="16dp"
            />

        <TextView
            android:id="@+id/txtItemName"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_toRightOf="@+id/item_photo"
            android:textSize="16sp"
            />

        <TextView
            android:id="@+id/txtItemQuantity"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/txtItemName"

            android:layout_toRightOf="@+id/item_photo"
            />

        <TextView

            android:layout_below="@+id/txtItemQuantity"
            android:layout_toRightOf="@+id/item_photo"
            />

    </RelativeLayout>
