是否可以在不使用位置偵聽器的情況下獲取Android MapView中的當前位置？

Question

我有一個MapView應用程序。當應用程序啓動時，它應顯示當前位置。這個怎麼做？

Answer 1

試試這個

public class MyLocationOnMap extends MapActivity { 

     private LocationManager hdLocMgr; 
     private String hdLocProvider; 


     onCreate(...) { 
      : 
     Criteria hdCrit = new Criteria(); 
     hdCrit.setAccuracy(Criteria.ACCURACY_COARSE); 
     hdCrit.setAltitudeRequired(false); 
     hdCrit.setBearingRequired(false); 
     hdCrit.setCostAllowed(true); 
     hdCrit.setPowerRequirement(Criteria.POWER_LOW); 

     hdLocMgr = (LocationManager) getSystemService(Context.LOCATION_SERVICE); 

     hdLocProvider = hdLocMgr.getBestProvider(hdCrit, true); 

     Location location = hdLocMgr.getLastKnownLocation(hdLocProvider); 

     Double dlat = location.getLatitude(); 
     Double dlon = location.getLongitude(); 
       : 
     } 

} 

Answer 2

使用位置管理器，您可以：獲取您的當前位置

選擇一個位置提供

String providerName = LocationManager.GPS_PROVIDER; 
LocationProvider gpsProvider; 
gpsProvider = locationManager.getProvider(providerName); 

查找位置提供使用標準

Criteria criteria = new Criteria(); 
criteria.setAccuracy(Criteria.ACCURACY_COARSE); 
criteria.setPowerRequirement(Criteria.POWER_LOW); 
criteria.setAltitudeRequired(false); 
criteria.setBearingRequired(false); 
criteria.setSpeedRequired(false); 
Criteria.setCostAllowed(true); 

String bestProvider = locationManager.getBestProvider(criteria, true); 

Location location = 
     locationManager.getLastKnownLocation(bestProvider); 
    updateWithNewLocation(location); 

    locationManager.requestLocationUpdates(bestProvider , 2000, 10, 
      locationListener);
