获取GPS状态的位置已更改

我正在使用GPS服务来获取纬度和频率在我的应用程序中的经度。当信号可用时,我能够获得纬度和经度。一旦我得到修复,如果我必须去GPS无法获得位置修复的地方,它仍然显示最后的位置。我想得到当前的位置而不是其他。我已经尝试使用onLocationChanged()和onGpsStatusChanged()两者来获取GPS状态,但它没有给我结果。

@Override
public void onGpsStatusChanged(int arg0) {
    // TODO Auto-generated method stub
    if (event == GpsStatus.GPS_EVENT_STARTED) {
        Log.d("zmenaGPS" , "GPS event started ");
        GpsStatus gs = mlocManager.getGpsStatus(null);
        Toast.makeText(getApplicationContext(),String.valueOf(gs),Toast.LENGTH_LONG).show();

    } else if (event == GpsStatus.GPS_EVENT_STOPPED) {
        Log.d("zmenaGPS" , "GPS event stopped ");
        GpsStatus gs = mlocManager.getGpsStatus(null);
        Log.d("zmenaGPSgps status" , String.valueOf(gs));
        Toast.makeText(getApplicationContext(),String.valueOf(gs),Toast.LENGTH_LONG).show();

    } else if (event == GpsStatus.GPS_EVENT_FIRST_FIX) {
        Log.d("zmenaGPS" , "GPS fixace ");
        Toast.makeText(getApplicationContext(),"First Fix",Toast.LENGTH_LONG).show();
    } else if (event == GpsStatus.GPS_EVENT_SATELLITE_STATUS) {
        Log.d("zmenaGPS" , "GPS EVET NECO ");
    } 

}

使用NETWORK_PROVIDER来获取所有时间的更新位置。 喜欢这个..

public Location getLocation() {
        try {
            locationManager = (LocationManager) mContext
                    .getSystemService(Context.LOCATION_SERVICE);

            // getting GPS status
            isGPSEnabled = locationManager
                    .isProviderEnabled(LocationManager.GPS_PROVIDER);

            // getting network status
            isNetworkEnabled = locationManager
                    .isProviderEnabled(LocationManager.NETWORK_PROVIDER);

            if (!isGPSEnabled && !isNetworkEnabled) {
                // no network provider is enabled
            } else {
                this.canGetLocation = true;
                if (isNetworkEnabled) {
                    locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 0, 0, locationListenerNetwork);
//                  locationManager.requestLocationUpdates(
//                          LocationManager.NETWORK_PROVIDER,
//                          MIN_TIME_BW_UPDATES,
//                          MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                    Log.d("Network", "Network");
                    if (locationManager != null) {
                        location = locationManager
                                .getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
                        if (location != null) {
                            latitude = location.getLatitude();
                            longitude = location.getLongitude();
                        }
                    }
                }
                // if GPS Enabled get lat/long using GPS Services
                if (isGPSEnabled){
                    if (location == null){
                        locationManager.requestLocationUpdates(LocationManager.GPS_PROVIDER, 0, 0, locationListenerGps);
//                      locationManager.requestLocationUpdates(
//                              LocationManager.GPS_PROVIDER,
//                              MIN_TIME_BW_UPDATES,
//                              MIN_DISTANCE_CHANGE_FOR_UPDATES, this);
                        Log.d("GPS Enabled", "GPS Enabled");
                        if (locationManager != null) {
                            location = locationManager
                                    .getLastKnownLocation(LocationManager.GPS_PROVIDER);
                            if (location != null) {
                                latitude = location.getLatitude();
                                longitude = location.getLongitude();
                            }
                        }
                    }
                }
            }
//          if (!isGPSEnabled) {
//              showSettingsAlert();
//          } 
        } catch (Exception e){
            e.printStackTrace();
        }

        return location;
    }

希望这有帮助

答案 1 :(得分:1)

听起来您想要获取当前位置,并且您想知道当前位置何时未知,因此您不要尝试使用旧位置。在这种情况下,您可以尝试获取当前位置,然后测试它是否旧。

long fresh=60000; // 1 minute in milliseconds
if(System.currentTimeMillis()-location.getTime()>fresh)
    // Do something useful with location

如果您无法使用GPS获取该位置,则可能需要使用NETWORK PROVIDER获取该位置,并与上次位置修复进行比较,以了解哪一个更好并相应地使用。
