A:

Hide dropdown icon
 <Spinner
  android:layout_width="wrap_content"
  android:layout_height="wrap_content"
  android:background="@android:color/transparent"/>

or cover another view
<RelativeLayout
  android:layout_width="match_parent"
  android:layout_height="wrap_content">

  <Spinner
      android:layout_width="match_parent"
      android:layout_height="wrap_content"
      android:layout_centerVertical="true"/>

  <ImageView
      android:layout_width="30dp"
      android:layout_height="30dp"
      android:layout_alignParentEnd="true"
      android:layout_centerVertical="true"
      android:background="#fff"/>
</RelativeLayout>
