Estou tentando adicionar uma simples Click View a um item de uma visão de reciclador, mas, por algum motivo, preciso clicar em um item duas vezes em vez de uma vez para executar uma ação. Com um único clique, parece que o Recycler View não detecta um clique. No próximo, porém, ele detecta o clique e executa uma ação adequada.

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_alignParentLeft="true"
            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:id="@+id/txtItemPrice"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_below="@+id/txtItemQuantity"
            android:layout_toRightOf="@+id/item_photo"
            />

    </RelativeLayout>

</android.support.v7.widget.CardView>
