Material Design Spinner

How to use this material design "spinner"

I'm just going to be honest and say this was stupid. It pissed me off because why would you remove a spinner to essentially make a text view? Google got too many people to be this annoying to devs. Anyway let me show you the xml and the kotlin code...

XML

fragment_main.xml

<com.google.android.material.textfield.TextInputLayout
            android:layout_width="250dp"
            android:layout_height="wrap_content"
            android:layout_marginTop="16dp"
            android:hint="@string/select_one"
     style="@style/Widget.MaterialComponents.TextInputLayout.OutlinedBox.Dense.ExposedDropdownMenu"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toTopOf="parent">

        <AutoCompleteTextView
            android:id="@+id/dropdown_value"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:inputType="none"/>

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

list_item_dropdown.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="10dp"
    android:maxLines="1"
    android:textAppearance="?attr/textAppearanceSubtitle1"/>

Kotlin File

MainFragment.kt

private var list = listOf("word 1", "word 2", "word 3")
val adapter = ArrayAdapter(requireContext(), R.layout.list_item_dropdown, actionList)
binding.dropdownValue.setAdapter(adapter)
binding.dropdownValue.setOnItemClickListener { parent, view, position, id ->
    Log.d("FRAG", list[position])
}

I do believe this is a cleaner dropdown menu but figuring this stuff out took like 2 days and I think that's a lot for something that should be simple. Regardless I hope this helps someone out. Save yourself time and prosper.
