Gruplar, aynı anda birden fazla bileşenin görünürlüğünü değiştirmek istediğinizde kullanabileceğiniz görünmeyen sarmalayıcılardır.
Örnek:
<androidx.constraintlayout.widget.Group
android:id="@+id/group"
android:visibility="gone"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:constraint_referenced_ids="textView1,textView2,textView3,barrier" />
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="16dp"
android:text="Header"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent" />
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginStart="16dp"
android:layout_marginTop="8dp"
android:text="Subheader"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toBottomOf="@+id/textView1" />
<androidx.constraintlayout.widget.Barrier
android:id="@+id/barrier"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
app:barrierDirection="end"
app:constraint_referenced_ids="textView2,textView1" />
<TextView
android:id="@+id/textView3"
android:layout_width="0dp"
android:layout_height="wrap_content"
android:layout_marginStart="8dp"
android:text="Test Text Test Text Test Text Test Text Test Text Test Text Test Text Test Text"
app:layout_constraintStart_toEndOf="@+id/barrier"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintTop_toTopOf="parent" />
Group'a ait android:visibility="gone" değeri visible yapılırsa,
