ConstraintLayout не переносит содержимое

Question

ConstraintLayout не переносит содержимое

У меня есть ограничение внутри карты. Кнопки расположены в виде сетки, как показано на рисунке. Но почему-то пробелы отображаются под кнопками. Я хочу удалить этот пробел.

Вот код XML

             <android.support.v7.widget.CardView
        android:id="@+id/cvSpecialisations"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp"
        app:cardElevation="2dp"
        app:layout_constraintLeft_toLeftOf="parent"
        app:layout_constraintRight_toRightOf="parent"
        app:layout_constraintTop_toBottomOf="@+id/bViewAll">

        <android.support.constraint.ConstraintLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content">


            <TextView

Ваш CardView не переносит содержимое, поскольку все вертикальные элементы должны быть помещены в "упакованную" цепочку.

Итак, я добавил app:layout_constraintVertical_chainStyle="packed" и некоторые дополнительные вертикальные поля:

<android.support.v7.widget.CardView
    android:id="@+id/cvSpecialisations"
    android:layout_width="0dp"
    android:layout_height="wrap_content"
    android:layout_marginTop="8dp"
    app:cardElevation="2dp"
    app:layout_constraintLeft_toLeftOf="parent"
    app:layout_constraintRight_toRightOf="parent"
    app:layout_constraintTop_toBottomOf="@+id/bViewAll" >

    <android.support.constraint.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content">

        <TextView
            android:id="@+id/tvSearchBySpecialisation"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="8dp"
            android:layout_marginLeft="8dp"
            android:layout_marginRight="8dp"
            android:text="Search by specialisation"
            android:textSize="14dp"
            app:layout_constraintTop_toTopOf="parent"
            app:layout_constraintLeft_toLeftOf="parent"

    </android.support.constraint.ConstraintLayout>

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

Это должно выглядеть так:
