通常使用FusedLocationProviderClient来获取我的智能手机的速度,但是即使它躺在我办公室的桌子上不动数小时,其速度值有时也会达到20,有时甚至超过100。 我相信原因是建筑物中的GPS信号不好? 这是我的代码:
locationRequest = new LocationRequest();
locationRequest.setInterval(1000);
locationRequest.setFastestInterval(1000);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);
locationCallback = new LocationCallback(){
@Override
public void onLocationResult(LocationResult locationResult){
super.onLocationResult(locationResult);
for(Location location : locationResult.getLocations()){
if (location != null) {
tv_speedField.setText("" + location.getSpeed());
}
}
}
};
