我正在尝试通过 GPS 的更新每秒向地图添加一个圆圈。我将如何传递位置 location = locationmanager.getLastKnownLocation(provider); 每秒做一个新的圈子？这是我到目前为止所拥有的。
public class MainActivity extends Activity implements LocationListener{
Location myLocation;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
GoogleMap mMap;
mMap = ((MapFragment) getFragmentManager().findFragmentById(R.id.map)).getMap();
mMap.setMyLocationEnabled(true);
Location myLocation;
LocationManager locationmanager = (LocationManager) getSystemService(LOCATION_SERVICE);
Criteria cr = new Criteria();
String provider = locationmanager.getBestProvider(cr, true);
Location location = locationmanager.getLastKnownLocation(provider);
locationmanager.requestLocationUpdates(provider, 1000, 0, (LocationListener) this);
CircleOptions circleOptions = new CircleOptions()
.center(new LatLng( , ))
.radius(3.048); // In meters
Circle circle = mMap.addCircle(circleOptions);
}
}
