我有一个Android应用程序,我正在使用带有位置侦听器的Google地图。当地图第一次出现时,我将位置侦听器中的缩放设置设置为12,我在Google地图开发中相当新,所以我想知道如何在不影响缩放的情况下更新位置,一旦用户捏住更改缩放?以下是我的位置监听器。如何在不更改用户设置的缩放的情况下更新地图标记?
/**
*Mylocationlistener class will give the current GPS location
*with the help of Location Listener interface
*/
private class Mylocationlistener implements LocationListener {
@Override
public void onLocationChanged(Location location) {
if (location != null) {
// ---Get current location latitude, longitude---
Log.d("LOCATION CHANGED", location.getLatitude() + "");
Log.d("LOCATION CHANGED", location.getLongitude() + "");
currentLocation = new LatLng(location.getLatitude(), location.getLongitude());
currentLatLng = new LatLng(location.getLatitude(), location.getLongitude());
Marker currentLocationMarker = map.addMarker(new MarkerOptions().position(currentLocation).title("Current Location"));
// Move the camera instantly to hamburg with a zoom of 15.
map.moveCamera(CameraUpdateFactory.newLatLngZoom(currentLatLng, 15));
// Zoom in, animating the camera.
map.animateCamera(CameraUpdateFactory.zoomTo(12), 2000, null);
if (!firstPass){
currentLocationMarker.remove();
}
firstPass = false;
Toast.makeText(MapViewActivity.this,"Latitude = "+
location.getLatitude() + "" +"Longitude = "+ location.getLongitude(),
Toast.LENGTH_LONG).show();
}
}
谢谢。有效。 – yams 2013-03-21 17:22:50
