android - Parent click event not firing when recyclerview clicked

Question

I have a RecyclerView which is in a CardView that has a couple of TextViews. The CardView has a OnClickListener set and is fired off when clicking on the TextViews, but does not fire when clicking on the RecyclerView.

Here is what the CardView looks like:

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.CardView
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:card_view="http://schemas.android.com/apk/res-auto"
    android:id="@+id/card_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_margin="5dp"
    card_view:cardCornerRadius="4dp"
    card_view:cardElevation="5dp">

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:weightSum="100"
        android:minWidth="100dp">

        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:id="@+id/text1"
            android:textColor="@color/abc_primary_text_material_light"
            android:layout_weight="1"
            android:layout_gravity="center_horizontal" />

        <android.support.v7.widget.RecyclerView
            android:id="@+id/recyclerView"
            android:layout_width="match_parent"
            android:layout_height="0dp"
            android:listSelector="@color/highlighted_text_material_light"
            android:layout_weight="98" />

        <View
            android:layout_width="match_parent"
            android:layout_height="1dp"
            android:background="@android:color/black" />

        <RelativeLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:id="@+id/relativeSummary"
            android:orientation="horizontal"
            android:layout_weight="1">

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceLarge"
                android:id="@+id/text2"
                android:textAlignment="viewEnd"
                android:textColor="@color/abc_secondary_text_material_light"
                android:layout_marginLeft="5dp"
                android:layout_marginRight="5dp"
                android:gravity="start"
                android:singleLine="true"
                android:layout_alignParentLeft="true" />

            <TextView
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:textAppearance="?android:attr/textAppearanceLarge"
                android:id="@+id/text3"
                android:textColor="@color/abc_primary_text_material_light"
                android:layout_marginRight="5dp"
                android:layout_marginLeft="5dp"
                android:gravity="end"
                android:singleLine="true"
                android:layout_alignParentRight="true"
                android:layout_toRightOf="@+id/text2" />

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

I do not need a click listener on this RecyclerView and really only need the parent view's click event to fire when the RecyclerView is clicked (The same goes for the OnLongClick event). I also need the RecyclerView to scroll. Is the RecyclerView some how eating the click event and not passing it up to the parent?

There is a better solution. That is, subclass your CardView:

public class InterceptTouchCardView extends CardView {

    public InterceptTouchCardView(Context context) {
        super(context);
    }

    public InterceptTouchCardView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public InterceptTouchCardView(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    /**
     * Intercept touch event so that inner views cannot receive it.
     * 
     * If a ViewGroup contains a RecyclerView and has an OnTouchListener or something like that,
     * touch events will be directly delivered to inner RecyclerView and handled by it. As a result, 
     * parent ViewGroup won't receive the touch event any longer.
     */
    @Override
    public boolean onInterceptTouchEvent(MotionEvent ev) {
        return true;
    }
}
