[英]Android current gps location incorrect
我正在使用三星spica 1.5测试当前的gps位置应用程序,但它不会显示我的当前位置,而只是显示另一个位置。
这是我的代码:
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;
private String current;
private PositionMarkersList positionMarkersList = 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);
mc = mapView.getController();
mc.setZoom(15);
myLocation = new MyLocationOverlay(getApplicationContext(), mapView);
myLocation.runOnFirstFix(new Runnable() {
public void run() {
mc.animateTo(myLocation.getMyLocation());
mc.setZoom(17);
}
});
mapView.getOverlays().add(myLocation);
GeoPoint pp=myLocation.getMyLocation();
//addPosition(pp);
if (myLocation.isMyLocationEnabled()!=false)
{
GeoPoint p =myLocation.getMyLocation();
lat= p.getLatitudeE6();
lng= p.getLongitudeE6();
Toast.makeText(getBaseContext(),
"geolocalisation activÈ lat: "+lat+ " long: " +lng,
Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(getBaseContext(),
"geolocalisation desactivÈe" ,
Toast.LENGTH_SHORT).show();
}
}
@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) {
}
//ajout d'une position
private void addPosition(GeoPoint geoPoint) {
OverlayItem overlayitem = new OverlayItem(geoPoint, current, current);
positionMarkersList.addMarker(overlayitem);
}
}
请问有人对此有任何想法吗?
当我单击“运行”以测试该应用程序时,我具有要测试的方式列表(虚拟设备...),但其中有一个“!” 靠近电话的名字,我也不知道为什么。
谢谢!
public Location getCurrentLocation() {
try {
LocationManager lm = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
// ---Get the status of GPS---
boolean isGPS = lm.isProviderEnabled(LocationManager.GPS_PROVIDER);
// If GPS is not enable then it will be on
if (!isGPS) {
Intent intent = new Intent(
"android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
sendBroadcast(intent);
}
Location location = lm
.getLastKnownLocation(LocationManager.GPS_PROVIDER);
if (location == null) {
location = lm
.getLastKnownLocation(LocationManager.NETWORK_PROVIDER);
}
return location;
} catch (Exception e) {
e.printStackTrace();
}
return null;
}
您必须使用Google API制作虚拟设备。
另外,在显示您的设备位置的位置上,我是否可以知道地图上显示的位置与您当前的位置有多远?
确保在AndroidManifest.xml中包含对位置服务的正确权限!!!!
GPS:ACCESS_FINE_LOCATION
WIFI:ACCESS_COARSE_LOCATION
