我在平板电脑上正在获取longitude=0.0
和latitude=0.0
,而在手机上可以正常使用。
我使用的是LocationManager.NETWORK_PROVIDER
而不是GPS_PROVIDER
,请问是什么原因?
Logcat输出?
那是我的代码:
// Acquire a reference to the system Location Manager
locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);
// Define a listener that responds to location updates
locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
// Called when a new location is found by the network location provider.
longitude=location.getLongitude();
latitude=location.getLatitude();
}
public void onStatusChanged(String provider, int status, Bundle extras) {}
public void onProviderEnabled(String provider) {}
public void onProviderDisabled(String provider) {}
};
//Or use LocationManager.GPS_PROVIDER
String locationProvider = LocationManager.NETWORK_PROVIDER;
// Register the listener with the Location Manager to receive location updates
locationManager.requestLocationUpdates(locationProvider, 0, 0, locationListener);
Location lastKnownLocation = locationManager.getLastKnownLocation(locationProvider);
if(lastKnownLocation!=null){
longitude=lastKnownLocation.getLongitude();
latitude=lastKnownLocation.getLatitude();
}
最佳答案
在设备设置中查看位置设置。这似乎与您的代码无关,但与您的设备设置有关。在我的Ginger面包中,它是:
设置->位置和安全->使用无线网络
