Indeed there is 1 problem, I want to apply a margin top de dropdown popup. I tried 1 thing for that which didn't work : popupTheme There is my spinner :

<androidx.appcompat.widget.AppCompatSpinner
                android:popupBackground="@color/bgChoicesSpinner"
                android:popupTheme="@style/popupOverlay"
                android:dropDownWidth="match_parent"
                android:layout_marginTop="30dp"
                android:layout_marginStart="5dp"

        <item name="android:layout_marginTop">10dp</item>
        <item name="android:background">@color/bgChoicesSpinner</item>
    </style>

Answer 1

Use the android:dropDownVerticalOffset="xxdp" attribute.

   <androidx.appcompat.widget.AppCompatSpinner
        android:spinnerMode="dropdown"
        android:dropDownVerticalOffset="40dp"
        ...
        />
