How to set background color on autocomplete exposed dropdown menu?

Currently working on setting up an Exposed Dropdown menu item using the material design components and guidelines for menus. However when displaying my autocomplete text view it does not have the same background as my other text fields.

I have tried setting the boxBackgroundColor attribute on the TextInputLayout to a different color and modifying background on the Autocomplete TextView. Also I have tired seeing if I could modify the popup theme for the menu but have had no luck.

 // In the onCreateView of fragment

        ArrayAdapter<String> adapter = new ArrayAdapter<>(getContext(), R.layout.dropdown_menu_popup_item, getResources().getStringArray(R.array.down_payment_method_selection));
        monthsAtEmploymentSelection.setAdapter(adapter);

<com.google.android.material.textfield.TextInputLayout
                style="@style/Widget.MaterialComponents.TextInputLayout.FilledBox.ExposedDropdownMenu"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:layout_marginStart="8dp"
                android:layout_marginEnd="8dp"
                android:hint="@string/months_at_employment_hint"
                app:boxBackgroundColor="@color/white">

                <AutoCompleteTextView
                    android:id="@+id/months_at_employment_selection"
                    android:layout_width="match_parent"
                    android:layout_height="wrap_content" />

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

<!--dropdown_menu_popup_item.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="wrap_content"
    android:padding="16dp"
    android:ellipsize="end"
    android:maxLines="1"
    android:textAppearance="?attr/textAppearanceSubtitle1"
    android:background="@color/white"/>

I would like the background to be transparent or match the current background that is set to white. Currently it is an off white that does not match the fields.

Thanks to this issue, I learn that this can be done programatically:

val autoCompleteTv = binding.yourAutoCompleteTextView
autoCompleteTv.setDropDownBackgroundDrawable(
        ColorDrawable(ContextCompat.getColor(context, R.color.your_desired_color))
)
