I have no issue with it being deprecated, and I prefer not to use the getMapAsync() if I don't have to. But here for some reason I recieve the error "Cannot resolve method 'getMap()'"我从另一个应用程序复制代码，其中方法getMap（）仅仅被弃用，所以我怀疑问题出在代码本身。我不推荐使用它，如果不需要，我更喜欢不使用getMapAsync（）。但由于某种原因，我收到了错误. I also recieve an error。我还收到错误Though I can't be sure if it's connected to this issue.虽然我无法确定它是否与此问题有关。The getMap() method was previously deprecated, and now it's been removed. If you look at the documentation for SupportMapFragment, it's not there.推荐答案您也可以在发行说明中查看 a>： $ bAnd from the blog post:从博客文章可以看到：So, just use getMapAsync(), it's simple.First have your Fragment implement the OnMapReadyCallback interface:首先让你的Fragment实现OnMapReadyCallback接口：public class FragmentWithMap extends android.support.v4.app.Fragment implements OnMapReadyCallback {Then, modify your setUpMapIfNeeded() code, and add the onMapReady() callback: $然后，修改你的setUpMapIfNeeded（）代码，并添加onMapReady（）回调： pre $ code > private void setUpMapIfNeeded（）{ if（mMap == null）{ SupportMapFragment mapFrag =（SupportMapFragment）getChildFragmentManager（）。findFragmentById（R.id.fragment_map2）; mapFrag.getMapAsync（this）; } } @Override public void onMapReady（GoogleMap googleMap）{ mMap = googleMap; setUpMap（）; }private void setUpMapIfNeeded() { if (mMap == null) { SupportMapFragment mapFrag = (SupportMapFragment) getChildFragmentManager().findFragmentById(R.id.fragment_map2); mapFrag.getMapAsync(this); }}@Overridepublic void onMapReady(GoogleMap googleMap) { mMap = googleMap; setUpMap();} 这篇关于无法解析方法getMap（）的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 1403页，肝出来的..
