Android Google Maps v2 - set zoom level for myLocation

Solution 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));
    }
}

Solution 2:

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.

Solution 3:

with location - in new GoogleMaps SDK:

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

Solution 4:

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 (note the "15f" below is street level) :

 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))

note: just so you know different locations can have different max zoom levels. try to use googleMap.maxZoomLevel if you want to get the max or min zoom levels.

Solution 5:

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));
