显示空白灰色地图的 Google 地图片段 [英] Google Maps fragment showing blank grey map

问题描述

我无法在我的地图片段中显示地图.我尝试了几种不同的解决方案，但地图仍然空白(灰色).有人可以指出我做错了什么吗?我使用的 SHA1 指纹是我在 Android > Build 中找到的指纹.

I'm having problems with getting the map in my map fragment to show. I have tried several different solutions but the map remains blank (grey). Can somebody please point out what I'm doing wrong? The SHA1 fingerprint I'm using is the one I found in Android > Build.

注意:上面写着来自开发者控制台的 api 密钥"，我当然已经输入了正确的密钥.

Fragment01.java

import com.google.android.gms.maps.CameraUpdate;
import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.MapView;
import com.google.android.gms.maps.MapsInitializer;
import com.google.android.gms.maps.model.LatLng;

import android.os.Bundle;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class Fragment01 extends Fragment {
MapView mapView;
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;
}
}

推荐答案

如果您得到一张灰色地图，则是与服务器的通信问题.重新检查您的 api 密钥，您是否在谷歌地图控制台中为 ANDROID 激活了谷歌地图?您在控制台中的包名称是否正确?你100%确定吗?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，则必须有一些日志，请检查您的 logcat 是否有来自 api 的警告

If you are getting a grey map it's a communication issue with the servers. Recheck your api key, did you activate google map in the google map console for ANDROID ? is your package name correct in the console ? Are you 100% sure ? If there is doubt ReCreate a debug apikey or release. Also if the map is grey there must be some log, check your logcat for warnings from the api
