Android Google Maps v2 - set zoom level for myLoca

问题:

Is it possible to change the zoom level for myLocation with the new Google Maps API v2? If you set GoogleMap.setEnableMyLocation(true); you get a button on the map to find your location. If you click on it, the map will bring you to your location and zoom it in to some level. Can I change this zoom to be less or more?

回答1:

It's doubtful you can change it on click with the default myLocation Marker. However, if you would like the app to automatically zoom in on your location once it is found, I would check out my answer to this question

Note that the answer I provided does not zoom in, but if you modify the onLocationChanged method to be like the one below, you can choose whatever zoom level you like:

@Override
public void onLocationChanged(Location location) 
{
    if( mListener != null )
    {
        mListener.onLocationChanged( location );

        //Move the camera to the user's location and zoom in!
        mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(location.getLatitude(), location.getLongitude()), 12.0f));
    }
}

You can also use:

mMap.animateCamera( CameraUpdateFactory.zoomTo( 17.0f ) );    

To just change the zoom value to any desired value between minimum value=2.0 and maximum value=21.0.

The API warns that not all locations have tiles at values at or near maximum zoom.

See this for more information about zoom methods available in the CameraUpdateFactory.

with location - in new GoogleMaps SDK:

mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(chLocation,14));

回答4:

Slightly different solution than HeatfanJohn's, where I change the zoom relatively to the current zoom level:

// Zoom out just a little
map.animateCamera(CameraUpdateFactory.zoomTo(map.getCameraPosition().zoom - 0.5f));

回答5:

In onMapReady() Method

change the zoomLevel to any desired value.

float zoomLevel = (float) 18.0;
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(latLng, zoomLevel));

Here are the approximate zoom levels and what they do :

1: World
5: Landmass/continent
10: City
15: Streets
20: Buildings

so you could do something like this to zoom to street level for example :

 override fun onMapReady(googleMap: GoogleMap?) {
    googleMap?.mapType = GoogleMap.MAP_TYPE_NORMAL
    googleMap?.addMarker(MarkerOptions()
            .position(LatLng(37.4233438, -122.0728817))
            .title("cool place")

            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_ROSE)))

    googleMap?.animateCamera(CameraUpdateFactory.newLatLngZoom(LatLng(37.4233438, -122.0728817), 15f))

回答7:

you have to write only one line in maps_activity.xml

map:cameraZoom="13"

I hope this will solve your problem...

回答8:

Location locaton;
double latitude = location.getlatitude;
double longitude = location.getlongitude;

If you want to save the zoom or get it all the time,you just need to call the following

int zoom = mMap.getCameraPosition().zoom;

//To set that just use

mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(getlatitude(), getlongitude),zoom);

回答9:

Even i recently had the same query....some how none of the above mentioned setmaxzoom or else map:cameraZoom="13" did not work So i found that the depenedency which i used was old please make sure your dependency for google maps is correct this is the newest use this

compile 'com.google.android.gms:play-services:11.8.0'

You can use

    CameraUpdate center = CameraUpdateFactory.newLatLng(new LatLng(location.getLatitude(), location.getLongitude()));
    CameraUpdate zoom = CameraUpdateFactory.zoomTo(12);
