android获取当前位置

Question

我正在测试一个使用 sumsung galaxy spica 获取当前位置的应用程序，它向我显示了与我的位置不同的另一个位置，并且与 AVD 中显示的位置不同!! gps 已激活，但我不知道问题到底出在哪里。这是我的代码

import android.location.Location;
import android.location.LocationListener;
import android.location.LocationManager;
import android.os.Bundle;
import android.view.KeyEvent;
import android.widget.Toast;

import com.google.android.maps.GeoPoint;
import com.google.android.maps.MapActivity;
import com.google.android.maps.MapController;
import com.google.android.maps.MapView;
import com.google.android.maps.MyLocationOverlay;

public class MaptestActivity extends MapActivity implements LocationListener {
    private MapView mapView = null;
    private LocationManager lm = null;
    private double lat = 0;
    private double lng = 0;
    private MapController mc = null;
    private MyLocationOverlay myLocation = null;

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    mapView = (MapView) this.findViewById(R.id.mapView);
    mapView.setBuiltInZoomControls(true);

    lm = (LocationManager) this.getSystemService(LOCATION_SERVICE);
    lm.requestLocationUpdates(LocationManager.GPS_PROVIDER, 10000, 0, this);
    lm.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 10000, 0, this);




    myLocation = new MyLocationOverlay(getApplicationContext(), mapView);
    myLocation.runOnFirstFix(new Runnable() {
        public void run() {
        mc.animateTo(myLocation.getMyLocation());
        mc.setZoom(17);
        mc = mapView.getController();
        lat = myLocation.getMyLocation().getLatitudeE6();
        lng = myLocation.getMyLocation().getLongitudeE6();
        Toast.makeText(
                getBaseContext(),
                "My Location : Latitude = " + lat + " Longitude = "
                    + lng, Toast.LENGTH_LONG).show();
        }
    });
    mapView.getOverlays().add(myLocation);
    }

    @Override
    protected void onResume() {
    super.onResume();
    myLocation.enableMyLocation();
    myLocation.enableCompass();
    }

    @Override
    protected boolean isRouteDisplayed() {
    return false;
    }

    @Override
    public boolean onKeyDown(int keyCode, KeyEvent event) {
    if (keyCode == KeyEvent.KEYCODE_S) {
        mapView.setSatellite(!mapView.isSatellite());
        return true;
    }
    return super.onKeyDown(keyCode, event);
    }

    public void onLocationChanged(Location location) {
    lat = location.getLatitude();
    lng = location.getLongitude();
    Toast.makeText(
        getBaseContext(),
        "Location change to : Latitude = " + lat + " Longitude = "
            + lng, Toast.LENGTH_SHORT).show();
    GeoPoint p = new GeoPoint((int) (lat * 1E6), (int) (lng * 1E6));
    mc.animateTo(p);
    mc.setCenter(p);
    }


    public void onProviderDisabled(String provider) {
    }


    public void onProviderEnabled(String provider) {
    }


    public void onStatusChanged(String provider, int status, Bundle extras) {
    }

}

这是我的 list

<?xml version="1.0" encoding="utf-8"?>

    package="com.manita.maptest"
    android:versionCode="1"

        <activity

    <uses-permission android:name="android.permission.ACCESS_COARSE" />
    <uses-permission android:name="android.permission.LOCATION" />

</manifest>

这里是 logcat 中的错误

我遇到了同样的问题

获取 GPS 信号时无需扩展 MapActivity

然后使用Activity，转发到MapActivity

虽然不知道原因:(
