How can I make the spinner width same as largest available item width

Question

I realize even I use wrap_content for my spinner (I avoid using match_parent as I do not want the spinner overly long), and using match_parent

In such Cases where you want to list all country or have big list
Try : spinnerMode="dialog" as show below :

<Spinner
    android:id="@+id/spinnerId"
    android:layout_width="wrap_content"
    android:dropDownWidth="match_parent"
    android:layout_height="wrap_content"
    android:layout_marginBottom="10dp"
    android:spinnerMode="dialog"/>
