Android中Google地图中的位置查询

Question

I have made an app utilizing Google Maps. I have added a marker of my current location in it. However, as soon as I open the app, I want it to zoom in to my location instead of showing the whole world at the 95302 23535919711008489 location first. How do I accomplish this?

Answer 1

Use animateCamera() as below

@Override
public void onLocationChanged(Location location) {
    LatLng latLng = new LatLng(location.getLatitude(), location.getLongitude());
    CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngZoom(latLng, 10);
    map.animateCamera(cameraUpdate);
    locationManager.removeUpdates(this);
}

Please read the docs

Answer 2

  LatLng cameraLatLng = new LatLng(savedLat, savedLng); googleMap = ((SupportMapFragment) getSupportFragmentManager() .findFragmentById(R.id.map)).getMap(); googleMap.animateCamera(CameraUpdateFactory .newLatLngZoom(cameraLatLng, 7)) 

savedLat, savedLng your current location longitude and latitude.You can change zoom number ( 7 ) to your fitting.
