Android-Android GPS定位，得到径纬度

Question

为什么location一直为NULL呢？由于是空

double lat = loc.getLatitude(); //径纬度也就得不到了
double lng = loc.getLongitude();

    LocationManager locationManager = (LocationManager) this.getSystemService(Context.LOCATION_SERVICE);  
    String provider = LocationManager.GPS_PROVIDER;  
    Location location = locationManager.getLastKnownLocation(provider); //为null!!!

Answer 1

你试试以下代码：

 LocationManager locationManager = (LocationManager) this.getSystemService(MainActivity.LOCATION_SERVICE);
Criteria criteria = new Criteria();
criteria.setAccuracy(Criteria.ACCURACY_FINE);
String provider = locationManager.getBestProvider(criteria, true);
Location location = locationManager.getLastKnownLocation(provider);

最后你提取location的对应值就OK了。
