注意：我在这个类中使用android.support.v4 lib

public class CustomMapFragment extends SupportMapFragment
因此，
CustomMapFragment
是一个
SupportMapFragment

view = inflater.inflate(R.layout.map_layout, container,false);
…您正试图将另一个
SupportMapFragment
充气到其中

这样做不好

可以使用
CustomMapFragment
extend
SupportMapFragment
（并删除其
onCreateView（）
plus
map\u layout.xml
）或使用您的
map\u layout.xml
。不要两者都做

在您的情况下，一切都很完美，只需检查是否在清单文件中添加了两个键

如果一切都和谷歌代码一样，那么请检查清单文件在我的情况下，我添加了地理键和地图键，这就是为什么会发生异常

注意-不要在清单文件中添加两个键删除映射键

meta-data
        android:name="com.google.android.maps.v2.API_KEY"
        android:value="@string/google_maps_key"/>
上面的代码并添加此代码

 <meta-data
        android:name="com.google.android.geo.API_KEY"
        android:value="@string/auto_location"/>

 <meta-data
        android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version"/>
