Group

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,
