ConstraintLayout not wrapping content
I have a constraintLayout inside a cardview. Buttons are arranged in grid format as shown in picture. But for some reason whitespace is displayed below buttons. I want to remove this whitespace.
Here is xml code
<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_marginRight="8dp"
android:layout_marginStart="8dp"

app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintTop_toTopOf="@+id/bSpecialisation5" />
</android.support.constraint.ConstraintLayout>
</android.support.v7.widget.CardView>
I have tried changing width and height to match_parent wrap_content

Your CardView doesn't wrap content because of all the vertical elements should be placed "packed" chain.
So I've added app:layout_constraintVertical_chainStyle="packed" and some additional vertical margins:
<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"
app:layout_constraintRight_toRightOf="parent"
app:layout_constraintBottom_toTopOf="@+id/vDividerInSpecialisationCard"
app:layout_constraintVertical_chainStyle="packed"/>
<View

app:layout_constraintTop_toBottomOf="@+id/tvSearchBySpecialisation"
app:layout_constraintLeft_toLeftOf="parent"
app:layout_constraintRight_toRightOf="parent"
