推荐答案

由于某种原因 SupportMapFragment 将我的位置按钮(或指南针图标)放置在 中时，它不显示我的位置按钮(或指南针图标).(<- 作为根视图)，但有一个解决方案:

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:

将整个 放入 并删除 并只放入整个 activity_mapsactivity_main 中的 .xml.同样为了让它看起来更好，我建议移动 activity_maps.xml 并从中制作一个片段，然后你将拥有:

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" />

您将只为片段中的地图分离逻辑，活动中的所有活动内容.而且我们都知道 MainActivity 往往会随着时间的推移而增长，原因有很多 ;)

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 ;)
