your problem can be solved easily following this actions:

1. Using a empty activity title (you can set the title with a empty string like "")

2. Use a spinner inside Toolbar layout with the spinner that your want.

   <android.support.v7.widget.Toolbar
       android:id="@+id/toolbar"
       android:layout_width="match_parent"
       android:layout_height="?attr/actionBarSize"
       android:background="?attr/colorPrimary"
       app:popupTheme="@style/ThemeOverlay.AppCompat.Light">
   
       <Spinner
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"/>
   </android.support.v7.widget.Toolbar>
   

3. Do whatever your want with your spinner. :)
