我已经阅读了很多关于这个问题的话题,但没有任何帮助。 所以我想在SupportMapFragment中运行GoogleMap。在FragmentActivity中,我在onCreate方法
中初始化了地图@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.content_frame);
// Initialize Google Maps Android API
try {
MapsInitializer.initialize(this);
} catch (GooglePlayServicesNotAvailableException e) {
e.printStackTrace();
}
...
我的MapFragment代码看起来与此完全相同
public class MapFragment extends SupportMapFragment {
private final String TAG = getClass().getSimpleName();
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.map, null);
}
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
}
@Override
public void onViewCreated(View view, Bundle savedInstanceState) {
super.onViewCreated(view, savedInstanceState);
GoogleMap gMap = this.getMap();
Log.d(TAG,
"getMap() " + ((gMap == null) ? "null" : gMap.toString()));
// Setting Location and Zoom
gMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(
40.76793169992044f, -73.98180484771729f), 14.0f));
}
}
每次我使用getMap方法获取null ...任何想法?

在将谷歌播放服务更新到最新版本后面临类似问题。 通过在清单
中添加元数据解决了我的问题<meta-data
android:name="com.google.android.gms.version"
android:value="@integer/google_play_services_version" />
