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 <a href="https://stackoverflow.com/questions/13739990/map-view-following-user-mylocationoverlay-type-functionality-for-android-maps/13753518#13753518">this question</a>
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:
<pre><code>@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));
 }
}
</code></pre>

You can also use:

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 <a href="https://developers.google.com/maps/documentation/android/reference/com/google/android/gms/maps/CameraUpdateFactory#zoomBy%28float,%20android.graphics.Point%29">this</a> for more information about zoom methods available in the <code>CameraUpdateFactory</code>.

Here are the <a href="https://developers.google.com/maps/documentation/android-sdk/views#zoom" rel="noreferrer">approximate zoom levels</a> and what they do :

<pre><code>1: World
5: Landmass/continent
10: City
15: Streets
20: Buildings
</code></pre>

so you could do something like this to zoom to street level for example (note the "15f" below is street level) :

<pre><code> 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))
</code></pre>

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

blocks|key|197358|text|与HeatfanJohn的解决方案略有不同，在HeatfanJohn的解决方案中，我相对于当前的缩放级别更改了缩放：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|197359|//+Zoom+out+just+a+little

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

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

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

//To set that just use

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

Is it possible to change the zoom level for myLocation with the new Google Maps API v2?

If you set <code>GoogleMap.setEnableMyLocation(true);</code>, you get a button on the map to find your location. 

If you click on it, then 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?

是否可以使用新的Google Maps API v2更改myLocation的缩放级别？如果您设置了GoogleMap.setEnableMyLocation(true);，您将在地图上获得一个按钮来查找您的位置。如果你点击它，地图会带你到你所在的位置，并将其放大到一定程度。我可以将此缩放更改为更小或更多吗？
