RIpple effect on RecyclerView not working on light tap

I have tried to implement the ripple effect on my RecyclerView. Here's my layout for it :

<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"
        android:layout_marginTop="7dp"
        android:layout_marginLeft="16dp"
        android:layout_marginRight="16dp"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        card_view:cardCornerRadius="5dp"
        android:clickable="true"
        card_view:cardElevation="5dp"
        android:focusable="true"
        android:foreground="?android:attr/selectableItemBackground">

            <LinearLayout
                android:layout_width="wrap_content"
                android:layout_height="wrap_content"
                android:orientation="vertical"
                android:padding="16dp">

                <TextView
                    //some properties />

                <TextView
                    //some properties />

                <TextView
                    //some properties />
            </LinearLayout>

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

In order to implement the onclick listener I basically followed this tutorial here: http://sapandiwakar.in/recycler-view-item-click-handler/

The problem is that the ripple effect,generated thanks to the lines :

android:clickable="true"
android:focusable="true"
android:foreground="?android:attr/selectableItemBackground"

is not working on light (it's to say quick) presses. When I just quickly tap the screen, the click listener is triggered. It means that the touch event have been detected, however there is no ripple effect showing. If I want to see the ripple effect, I have to maintain for a bit longer the pressure on the screen before releasing.

Is there a way to correct this behaviour and show a ripple effect even for quick presses?

This happens because you have used addOnItemTouchListener for item click listener. Just create an interface in RecyclerAdapter

In adapter create an interface

public interface OnItemClickListener {
    void onItemClick(Item item);
}

private final List<ContentItem> items;
private final OnItemClickListener listener;

public Adapter(List<ContentItem> items, OnItemClickListener listener) 
{
   this.items = items;
   this.listener = listener;
}

@Override 
public void onBindViewHolder(ViewHolder holder, int position) {
   holder.bind(items.get(position), listener);
}


//In your Activity
recycler.setAdapter(new Adapter(items, new 
Adapter.OnItemClickListener() {
@Override public void onItemClick(ContentItem item) {
    Toast.makeText(getContext(), "Item Clicked", Toast.LENGTH_LONG).show();
}
}));

instead of below code and it will work like a charm.

recyclerView.addOnItemTouchListener( 
    new RecyclerItemClickListener(context, new RecyclerItemClickListener.OnItemClickListener() {
      @Override public void onItemClick(View view, int position) {
        // TODO Handle item click
      }
   })
);

Asked long ago but thought it might help someone, I faced the similar issue and used postDelayed method .

   ( new Handler()).postDelayed(new Runnable() {
        @Override
        public void run() {
           //your code 
        }
    }, 100);
