GridLayout 佈局中, 怎麼設定header 為一橫條

我依照這邊的只是施作想達到一樣的效果

預期

但實際變成這樣

我設定RecylerView是如下設置
...
viewBinding.recyclerView.setAdapter(adapter);
viewBinding.recyclerView.setHasFixedSize(true);
GridLayoutManager gridLayoutManager = new GridLayoutManager(viewBinding.getRoot().getContext(), 2);
viewBinding.recyclerView.setLayoutManager(gridLayoutManager);

...

header view xml

<androidx.constraintlayout.widget.ConstraintLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="56dp">

<ImageView
    android:id="@+id/imageView13"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="16dp"
    android:src="@mipmap/face_003"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toStartOf="parent"
    app:layout_constraintTop_toTopOf="parent"/>

<TextView
    android:id="@+id/title"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginStart="8dp"
    android:text="誒羅喔誒羅"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintStart_toEndOf="@+id/imageView13"
    app:layout_constraintTop_toTopOf="parent" />

<TextView
    android:id="@+id/moreBtn"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_marginEnd="16dp"
    android:text="ＭotoMoto >>"
    app:layout_constraintBottom_toBottomOf="parent"
    app:layout_constraintEnd_toEndOf="parent"
    app:layout_constraintTop_toTopOf="parent" />

</androidx.constraintlayout.widget.ConstraintLayout>

Start by comparing the Add-group wiki example with the shown RecyclerView and GridLayoutManager setup. Review the header view XML and determine why the header does not occupy the full two-column row. Done means the header matches the expected full-width screenshot while the item grid remains two columns.
