How to get zoom level from CameraUpdate - android

My requirement is MAX_ZOOM_LEVEL = 14.
Calculating zoom using bounds zoom more than MAX_ZOOM_LEVEL.
LatLngBounds.Builder boundsBuilder = new LatLngBounds.Builder();
if (i < maxNearestMarkers) {
boundsBuilder.include(marker.getPosition());
}
CameraUpdate boundCameraUpdate = CameraUpdateFactory.newLatLngBounds(bounds, width,height,padding);
map.animateCamera(boundCameraUpdate);
CameraUpdate class
public final class CameraUpdate {
private final zzd zzaRp;
CameraUpdate(zzd remoteObject) {
this.zzaRp = (zzd)zzx.zzz(remoteObject);
}
public zzd zzzH() {
return this.zzaRp;
}
}
so how to get zoom level before animating camera to new CameraUpdate.
I required something like algo given below before map.animateCamera(boundCameraUpdate);
if cameraUpdate.zoom > MAX_ZOOM_LEVEL
then cameraUpdate.zoom = MAX_ZOOM_LEVEL
THANKSSS
Note: already doing so but it's zoom in and bounce back to MAX_ZOOM_LEVEL
#Override
public void onCameraChange(CameraPosition cameraPosition) {
mZoom = cameraPosition.zoom;
Log.d("Zoom", String.valueOf(cameraPosition.zoom));
if (cameraPosition.zoom > MAX_ZOOM_LEVEL) {
map.animateCamera(CameraUpdateFactory.zoomTo(MAX_ZOOM_LEVEL));
}
}

Google maps style with a marker cluster

can i add a Map style with a marker cluster in android? because i try with this line:
#Override
public void onMapReady(GoogleMap googleMap) {
mMap = googleMap;
mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
MapStyleOptions style = loadRawResourceStyle(Mapa.this, R.raw.estilo_map);
mMap.setMapStyle(style);
mMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(-33.502482, -70.573841), 8));
mMap.getUiSettings().setMapToolbarEnabled(false);
mMap.getUiSettings().setMyLocationButtonEnabled(true);
mMap.getUiSettings().setZoomControlsEnabled(false);
if (ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
return;
}
mMap.setMyLocationEnabled(true);
mMap.setMinZoomPreference(10);
mMap.setMaxZoomPreference(20);
mMap.setLatLngBoundsForCameraTarget(new LatLngBounds(new LatLng(-33.660048, -70.801025),new LatLng(-33.271212, -70.471835)));
mClusterManager = new ClusterManager<>(Mapa.this, mMap);
RenderClusterInfoWindow renderer = new RenderClusterInfoWindow(Mapa.this, mMap, mClusterManager);
mClusterManager.setRenderer(renderer);
mMap.setOnCameraIdleListener(mClusterManager);
mMap.setOnMarkerClickListener(mClusterManager);
mMap.setOnInfoWindowClickListener(mClusterManager);
clusterMarcadores();
mClusterManager.setOnClusterItemClickListener(new ClusterManager.OnClusterItemClickListener<FormatoMarcadores>() {
#Override
public boolean onClusterItemClick(FormatoMarcadores formatoMarcadores) {//abrir valorar y reportar aqui
Log.d("ciclovia", formatoMarcadores.getTitle());
d.ruta(formatoMarcadores.getTitle(), mMap);
markerClick(formatoMarcadores.getTitle(),formatoMarcadores.getPosition());
return false;
}
});
mClusterManager.setOnClusterClickListener(new ClusterManager.OnClusterClickListener<FormatoMarcadores>() {
#Override
public boolean onClusterClick(Cluster<FormatoMarcadores> cluster) {
mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(cluster.getPosition(), (float) Math.floor(mMap.getCameraPosition().zoom + 2)));
return true;
}
});
mClusterManager.cluster();
mMap.setOnMapClickListener(new GoogleMap.OnMapClickListener() {
#Override
public void onMapClick(LatLng latLng) {
d.quitarPolyline();
if (bottomSheet.isHideable()){
bottomSheet.setState(BottomSheetBehavior.STATE_HIDDEN);
}
}
});
}
and i have this: link to picture
maps works perfectly without style, and if i use the mMap.setMapStyle(style); as boolean, i get the style is applied correctly
Create you map theme from here
Download your style.json -> copy in raw resorce file
mGoogleMap.setMapStyle(

DefaultClusterRenderer getMarker() returning null when zooming

I want to change the background of the cluster marker on click. I do this via
#Override
onClusterClick(Cluster<MyObject> cluster) {
Marker marker = renderer.getMarker(cluster);
marker.setIcon(....);
}
This works fine expect for one case: When I zoom in or out and the number of cluster markers doesn't change. For example, if I had a 15 cluster and a 5 cluster, then zoom a level in or out, the same two clusters remain. Clicking on one of these now renderer.getMarker(cluster) returns null. If they re-cluster after zooming, getMarker is not null.
My DefaultClusterRenderer is below. I checked the marker on onClusteredRendered and it's never null. Is this a bug in the DefaultClusterRenderer or should I do something else?
private class MyRenderer extends DefaultClusterRenderer<MyObject> {
private IconGenerator iconGenerator;
private float density;
public MyRenderer(Context context, GoogleMap map, ClusterManager<MyObject> clusterManager) {
super(context, map, clusterManager);
density = context.getResources().getDisplayMetrics().density;
}
#Override
protected void onBeforeClusterItemRendered(MyObject item, MarkerOptions markerOptions) {
markerOptions.icon(BitmapDescriptorFactory.fromResource(R.drawable.my_pin));
}
#Override
protected void onBeforeClusterRendered(Cluster<MyObject> cluster, MarkerOptions markerOptions) {
if(iconGenerator == null) {
iconGenerator = new IconGenerator(getActivity());
iconGenerator.setContentView(makeTextView(getActivity()));
}
iconGenerator.setBackground(makeBackground(false));
markerOptions.icon(BitmapDescriptorFactory.fromBitmap(iconGenerator.makeIcon(String.valueOf(cluster.getSize()))));
}
#Override
protected void onClusterRendered(Cluster<MyObject> cluster, Marker marker) {
super.onClusterRendered(cluster, marker);
// Marker is never null here
}
#Override
protected boolean shouldRenderAsCluster(Cluster<MyObject> cluster) {
return cluster.getSize() > 1;
}
private ShapeDrawable makeBackground(boolean isClicked) {
ShapeDrawable background = new ShapeDrawable(new OvalShape());
background.setColorFilter(ContextCompat.getColor(getActivity(),
isClicked ? R.color.cluster_marker_clicked : R.color.cluster_marker_unclicked), PorterDuff.Mode.SRC_ATOP);
return background;
}
private SquareTextView makeTextView(Context context) {
SquareTextView squareTextView = new SquareTextView(context);
ViewGroup.LayoutParams layoutParams = new ViewGroup.LayoutParams(-2, -2);
squareTextView.setLayoutParams(layoutParams);
squareTextView.setTextColor(ContextCompat.getColor(getActivity(), R.color.white));
squareTextView.setTypeface(Utils.getFontBold(getActivity()));
squareTextView.setId(com.google.maps.android.R.id.text);
int twelveDpi = (int) (12.0F * density);
squareTextView.setPadding(twelveDpi, twelveDpi, twelveDpi, twelveDpi);
return squareTextView;
}
public IconGenerator getIconGenerator(boolean isClicked) {
iconGenerator.setBackground(makeBackground(isClicked));
return iconGenerator;
}
}
Initializing the ClusterManager:
final ClusterManager<MyObject> mClusterManager = new ClusterManager<>(getActivity(), googleMap);
mClusterManager.addItems(items);
renderer = new CustomRenderer(getActivity(), googleMap, mClusterManager);
mClusterManager.setRenderer(renderer);
mClusterManager.cluster();
mClusterManager.setOnClusterItemClickListener(this);
googleMap.setOnMarkerClickListener(mClusterManager);
#antonio: This initialization is working for me:
public class MapsActivity extends FragmentActivity
implements ClusterManager.OnClusterClickListener<MyObject> {
// ...
private void setUpClusterer() {
googleMap.moveCamera(CameraUpdateFactory.newLatLngZoom(new LatLng(51.503186, -0.126446), 10));
mClusterManager = new ClusterManager<MyObject>(this, googleMap);
mClusterManager.setOnClusterClickListener(this);
renderer = new MyRenderer(this, googleMap, mClusterManager);
mClusterManager.setRenderer(renderer);
googleMap.setOnCameraChangeListener(mClusterManager);
googleMap.setOnMarkerClickListener(mClusterManager);
addItems();
}
private void addItems() {
// Set some lat/lng coordinates to start with.
double lat = 51.5145160;
double lng = -0.1270060;
// Add ten cluster items in close proximity, for purposes of this example.
for (int i = 0; i < 10; i++) {
double offset = i / 60d;
lat = lat + offset;
lng = lng + offset;
MyObject offsetItem = new MyObject(lat, lng);
mClusterManager.addItem(offsetItem);
}
}
#Override
public boolean onClusterClick(final Cluster<MyObject> cluster) {
Marker marker = renderer.getMarker(cluster);
marker.setIcon(BitmapDescriptorFactory.fromResource(R.drawable.my_newpin));
return true;
}
}
Couldn't get renderer.getMarker(cluster) to return a marker in that case above. A work around was to create:
Map <Cluster<MyObject>, Marker> clusterMarkerMap = new HashMap<>();
then add them on the DefaultClusterRenderer callback because the marker is never null there:
#Override
protected void onClusterRendered(Cluster<MyObject> cluster, Marker marker) {
super.onClusterRendered(cluster, marker);
clusterMarkerMap.put(cluster, marker);
}
Because the DefaultClusterManager clears them when the camera position changes, wipe the cluster marker map before it creates new ones:
googleMap.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition cameraPosition) {
// Clear the map here because the markers will be recreated
// when the manager is notified of a (zoom level) camera change
if(zoomLevelChanged)
clusterMarkerMap.clear();
mClusterManager.onCameraChange(cameraPosition);
}
});
Now I can get the marker successfully clusterMarkerMap.get(cluster)

Google map on camera change going in a circular loop

On camera change gets called again and again while animation is going on in google maps. Is it getting triggered because the animation has not finished? If so, how to get the callback which notifies the animation has stopped.
Here is my code:
map.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition cameraPosition) {
showLocations(location);
}
});
private void showLocations() {
for (int i = 0; i < 2; i++) {
Marker m = map.addMarker(new MarkerOptions().position(latlngs.get(i))
.icon(BitmapDescriptorFactory.fromResource(R.drawable.some_icon)));
markers.add(m);
}
LatLngBounds.Builder builder = new LatLngBounds.Builder();
for (Marker marker : markers) {
builder.include(marker.getPosition());
}
LatLngBounds bounds = builder.build();
CameraUpdate cameraUpdate = CameraUpdateFactory.newLatLngBounds(bounds, 100);
map.animateCamera(cameraUpdate);
}
Calling map.animateCamera() causes the OnCameraChangeListener to be called, so you can't change the camera unless you're planning on removing the listener as part of its logic. For example:
map.setOnCameraChangeListener(new GoogleMap.OnCameraChangeListener() {
#Override
public void onCameraChange(CameraPosition cameraPosition) {
map.setOnCameraChangeListener(null);
showLocations(location);
}
});
