Last item covered by bottom navigation

Question

So, I have this problem. My last item of recyclerview is covered by my bottom navigation. The bottom navigation is in activity. The recyclerview is in the fragment. I not found the answer.

Here is my fragment layout, which contain the recyclerview

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    tools:context=".PromoFragment">

    <!-- TODO: Update blank fragment layout -->
    <android.support.v7.widget.RecyclerView
        android:id="@+id/promo_recyclerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"
        android:layout_marginBottom="110dp">

    </android.support.v7.widget.RecyclerView>
</android.support.constraint.ConstraintLayout>

Here is my item layout that I use in recyclerview

<android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:padding="5px">

        <android.support.v7.widget.CardView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:layout_marginStart="8dp"
            android:layout_marginTop="8dp"
            android:layout_marginEnd="8dp"
            android:id="@+id/card_pertama"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">

               <include layout="@layout/card_promo_layout"/>

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

</android.support.constraint.ConstraintLayout>

Here is the image of the result from my code

Add android:paddingBottom="56dp" to your Fragment that contains RecyclerView or to the closest parent layout of RecyclerView. For example:

<android.support.constraint.ConstraintLayout 
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:paddingBottom="56dp"
    tools:context=".PromoFragment">

    <!-- TODO: Update blank fragment layout -->
    <android.support.v7.widget.RecyclerView
        android:id="@+id/promo_recyclerview"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">
    </android.support.v7.widget.RecyclerView>
</android.support.constraint.ConstraintLayout>

P.S. 56dp - is the height of BottomNavigationView according to Material Design. So value of paddingBottom must be the same as the height of BottomNavigationView
