回答1:

For some reason SupportMapFragment does not show my location button (or compass icon) when its placed inside <DrawerLayout> (<- as a root view), but there is a solution:

Put the whole <DrawerLayout> in <RelativeLayout> and remove <include> and just put whole activity_maps.xml in activity_main. Also to make it look better I would recommend moving activity_maps.xml and make a fragment from it, and then instead of <include> you would have:

<fragment
    android:id="@+id/map_fragment"
    class="com.yourpackage.MapFragment"
    android:layout_width="match_parent"
    android:layout_height="match_parent" />

You will have separated logic only for map in the fragment, an all activity stuff in activity. And we all know that MainActivity tends to grow over time for many reasons ;)
