我在地图片段中显示地图时遇到问题。我尝试了几种不同的解决方案,但地图仍为空白(灰色)。有人可以指出我做错了什么吗?我正在使用的SHA1指纹是我在 Android>中找到的指纹。构建
注意:如果它显示“来自开发者控制台的api密钥”,我当然会输入正确的密钥。

GoogleMap map;
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_01, container, false);
// Gets the MapView from the XML layout and creates it
mapView = (MapView) v.findViewById(R.id.map);
mapView.onCreate(savedInstanceState);
// Gets to GoogleMap from the MapView and does initialization stuff
map = mapView.getMap();
map.getUiSettings().setMyLocationButtonEnabled(false);
map.setMyLocationEnabled(true);
// Needs to call MapsInitializer before doing any CameraUpdateFactory calls
MapsInitializer.initialize(this.getActivity());
// Updates the location and zoom of the MapView
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(new LatLng(43.1, -87.9), 10);
map.animateCamera(cameraUpdate);
return v;

如果您获得灰色地图,则表明服务器存在通信问题。重新检查您的api密钥,您是否在谷歌地图控制台中激活了谷歌地图以获取ANDROID?控制台中的包名是否正确?你100%肯定吗?如果有疑问请重新创建调试apikey或发布。此外,如果地图是灰色的,必须有一些日志,请检查您的logcat以获取来自api的警告

更改硬盘后我遇到了同样的问题。
我在谷歌控制台上创建新的Api密钥,新的SHA1后解决了我的问题。
