In Android, how to create an outlined dropdown menu (spinner) as specified by the material design documentation? [closed]

They’ve updated material design library:

<com.google.android.material.textfield.TextInputLayout
    style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.ExposedDropdownMenu"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:hint="@string/hint_text">

  <com.google.android.material.textview.MaterialAutoCompleteTextView
      android:id="@+id/filled_exposed_dropdown"
      android:layout_width="match_parent"
      android:layout_height="wrap_content"/>

</com.google.android.material.textfield.TextInputLayout>
