MapFragment.getMap()自2014年12月起就被弃用,随着2016年6月27日的新版本,getMap()已被删除。现在,好的(也是唯一的)方法是使用getMapAsync()

有关更多详细信息,请参阅:

以前不推荐使用的getMap()函数在Google Play services SDK中不再可用。(它仍然可以在Android设备上提供的Google Play services APK中使用。)getMap()函数自2014年12月以来一直被弃用。有关从getMap()转换为getMapAsync()的帮助,请参阅发布日志

你可以看一下


如果您在从getMap()切换到getMapAsync()时遇到问题,您还可以查看答案。
