Answer 1

You can also remove the padding of spinner in xml

Only need to set padding to 0dp.

    <Spinner
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_gravity="left"
        android:padding="0dp"     
        android:id="@+id/my_spinner">

Answer 2

If yo don't want to mess in Java Code and have it in styles

Search for this file (Cmd+Shift+O) abc_spinner_textfield_background_material.xml

and copy to your project. Remove all inset values from root element and refer the file as background of your spinner.

In my case it looks like this (drawable/spinner_background.xml)

<inset xmlns:android="http://schemas.android.com/apk/res/android">
    <selector>
        <item
            android:state_checked="false"
            android:state_pressed="false">
            <layer-list>
                <item android:drawable="@drawable/abc_textfield_default_mtrl_alpha" />
                <item android:drawable="@drawable/abc_spinner_mtrl_am_alpha" />
            </layer-list>
        </item>
        <item>
            <layer-list>
                <item android:drawable="@drawable/abc_textfield_activated_mtrl_alpha" />
                <item android:drawable="@drawable/abc_spinner_mtrl_am_alpha" />
            </layer-list>
        </item>
    </selector>
</inset>

and in my styles.xml I use it this way

<style name="DxSpinner" parent="@style/Widget.AppCompat.Spinner.Underlined">
    <item name="android:background">@drawable/spinner_background</item>
</style>
