Question

Answer 1

In your layout put a spinner, for example

<Spinner
    android:id="@+id/spinner"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:spinnerMode="dropdown"/>

Then, create an adapter for your spinner See here 'how to'

for 2 scroll list, you can do it like this in your adapter item layout

<LinearLayout
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:orientation="horizontal">

    <NumberPicker
        android:id="@+id/picker_month"
        android:layout_width="wrap_content"
        android:theme="@style/NumberPickerText"
        android:layout_height="wrap_content"
        android:layout_marginEnd="20dp"
        android:layout_marginRight="20dp">

    </NumberPicker>

    <NumberPicker
        android:id="@+id/picker_year"
        android:theme="@style/NumberPickerText"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content">

    </NumberPicker>

</LinearLayout>
