Please take a look at my xml:

<android.support.constraint.ConstraintLayout
    android:id="@+id/constraintLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="?attr/actionBarSize">

    <RelativeLayout
        android:id="@+id/layout_info"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimaryDark"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent"/>

    <include
        layout="@layout/page"
        android:layout_width="match_parent"
        android:layout_height="0dp"/>

</android.support.constraint.ConstraintLayout>

I'm not able to add constraint to the <include>. The app namespace doesn't work (it works for the RelativeLayout) and auto fill doesn't show the constraint attributes. I want the included layout's height to be the remaining space in the ConstraintLayout, but how do I do it without constraints! Please help.

<include layout="@layout/layout_no_friends_avalable"
                 android:id="@+id/inc_no_friend"
                 android:layout_width="match_parent"
                 android:layout_height="0dp"
                 app:layout_constraintBottom_toBottomOf="parent"
                 app:layout_constraintEnd_toEndOf="parent"
                 app:layout_constraintTop_toBottomOf="@+id/toolbar_main"
        />

When adding constraints in <include> tag we must use android:layout_width and android:layout_height both attributes.
