mapFragment.getMap()将返回Null getMapAsync (OnMapReadyCallback callback)方法答案 1 :(得分：0)
我有同样的问题，我解决了。 解决方案不是添加
<fragment
android:id="@+id/map"
android:name="com.google.android.gms.maps.SupportMapFragment"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="center" />
在您的布局中。
在Fragment / Activity中按代码添加SupportMapFragment！注意：在添加之前，您需要检查它是否已添加。如果您需要，我会稍后展示我的代码！
