出现错误是因为Google已经删除了
getMap()
,但我不知道有什么替代方案。更新
在您的主要活动中定义private GoogleMap gMap
并实施OnMapReadyCallback
并实施onMapReady
方法
SupportMapFragment supportMapFragment = (SupportMapFragment)
getSupportFragmentManager().findFragmentById(R.id.map);
supportMapFragment.getMapAsync(this);
在onMapReady
中,您应该写这一行
gMap=googleMap
,那么你就可以在onMapReady中做你想做的事了
- 获取当前位置
- 自定义地图设置
- 而且
OnCreate
方法中使用这些行的时候了
SupportMapFragment supportMapFragment = (SupportMapFragment)
getSupportFragmentManager().findFragmentById(R.id.map);
supportMapFragment.getMapAsync(this);
它应该可以解决您的问题,希望它能帮助您我要求我在4月份实现,您能提供更多的代码吗?
