Question

我正在尝试使用FusedLocationApi获取用户当前位置，即使没有wifi或移动网络也是如此。

如何使用融合的位置API实现此目标？？

位置管理器具有此功能，我不想像在保险丝位置中那样使用位置管理器，因此我得到了最准确的结果，如何实现这一点，所以让我发表到目前为止的尝试

请参阅下面的代码

   mGoogleApiClient = new GoogleApiClient.Builder(this)
            .addConnectionCallbacks(this)
            .addOnConnectionFailedListener(this)
            .addApi(LocationServices.API).build();

    mGoogleApiClient.connect();

    mLocationRequest = new LocationRequest();
    mLocationRequest.setInterval(10000);
    mLocationRequest.setFastestInterval(5000);
    mLocationRequest.setSmallestDisplacement(300);
    mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
        PendingResult<Status> statusPendingResult = 
   LocationServices.FusedLocationApi.requestLocationUpdates(mGoogleApiClient, mLocationRequest, new LocationCallback() {
                        @Override
                        public void onLocationResult(LocationResult result) {
        Log.d("TAG", "onLocationResult" + result.getLastLocation().getLatitude() + " " + result.getLastLocation().getLongitude());
                        }

                        @Override
                        public void onLocationAvailability(LocationAvailability locationAvailability) {

                            Log.d("TAG", "onLocationAvailability: isLocationAvailable =  " + locationAvailability.isLocationAvailable());
                        }
                    }, null);

                    statusPendingResult.setResultCallback(new ResultCallback<Status>() {

                        @Override
                        public void onResult(Status status) {
                            if (status.getStatus().isSuccess()) {

                                Log.d("TAG", "Successfully requested location updates");

                            } else {

                                CommonMethods.setAddress("Couldn't find the location");
                                Toast.makeText(MainActivity.this, "Couldn't get the location. Make sure location is enabled on the device", Toast.LENGTH_SHORT).show();

                                Log.e("TAG",
                                        "Failed in requesting location updates, "
                                                + "status code: "
                                                + status.getStatusCode() + ", message: " + status
                                                .getStatusMessage());
                            }
                        }
                    });

通过添加此行

mLocationRequest.setSmallestDisplacement(300);

您意识到两个位置之间的差异距离应该为300米，您是否试图覆盖那么远的距离？

尝试将其删除

无法使用FusedLocationApi使位置离线（没有Wifi或移动网络）
