changing getMap to GetMapAsync

I am trying to create an interactive infoWindow based on one of the answers from Stack Overflow.
However, I am getting an error with getMap() used in the code. Although I've tried with getMapAsync(), I'm unable to resolve the problem. Please help me. If any new code is available for an interactive infowindow with a button, then please share the code.

The error is coming because Google has removed getMap(), but I dont know the alternative solution for this.

UPDATE
Define private GoogleMap gMapand implement OnMapReadyCallback in your main Activity and implement onMapReady method
in onMapReady you should write this line
gMap = googleMap, then you can do what you want in onMapReady
getting current location
custom setting for your map
and ...
now it's time to use this lines in your OnCreate method
SupportMapFragment supportMapFragment = (SupportMapFragment)
getSupportFragmentManager().findFragmentById(R.id.map);
supportMapFragment.getMapAsync(this);
it should solve your problem, hope it helped you

how to get direction to the shortest path outside circle in google maps android, when my current location is inside 2 or more circles?

How to get direction to the nearest location outside circle if the blue dots is the current location?
1[1
and how to display markers ONLY around the current location in radius 2000m? I have stored the mapping lanslide in database and it displays when the app launch and it needs 7-9 seconds to load these markers. now i need to display only around the current location in order the app going smooth.
[these are the mapping dots of lanslide]
im doing my final projet, and I have a fEature which is really difficult.
Im on my android project, making a warning application on android about lanslide disaster, I do the mapping dots of lanslide locations and collect about 150 couples of lattitudes and longitudes and put it on database.
I assume if the user inside a circle, they are in lanslide location and they are not safe
the red zone radius is 2KM from the center of circle.
the orange zone radius is 1km from the center of circle.
the yellow zone radius is 500m from the center of circle
when the app is launch, the map will show up and animate the camera to my current location.
and then the app will tell the user if they are safe or not.
if the user OUTSIDE THE CIRCLE, then the user is safe. but,
if the current location inside the circle, then the user is not safe.
WHEN THE USER IS NOT SAFE, THE APP will give direction to shortest path outside the circle.
My app is almost done, except the last feature, I'm out of idea how to figure it out,
HOW THE APP CAN GIVE THE DIRECTION TO THE SHORTEST PATH OUTSIDE A CIRCLE??
unfortunately, how can the app will get direction to the shorthest outside circle for user if the CURRENT LOCATION inside 3 or mores circle ? and what google's libarry i can use for solve this?
how to get direction outside many circles? please help me.

In order to show directions you need 2 points the origin and destination. The origin in this case will be your user's location.
Finding the destination point:
1) Currently you are storing the centre of these circular zones and their radii (500m, 1km etc). In addition to these you can easily calculate for each circle 4 'safe' points that lie along 4 directions (say N,S,E,W) and store them.
2) These points divide your circle into 4 quadrants. Now all you need to do is find which quadrant of the circle the user's current location is in and compare the distance between the points forming the quadrant and choose the lower of the two as your destination.
3) Use the Google Maps Directions API to show directions .
If you want to increase the accuracy of the algorithm all you need to do is increase the number of directions which will effectively divide your circle into more smaller parts and the destination will be more optimal.
Here '4' was just an arbitrary number . You can have different number based on number of safe points you choose and that will determine the accuracy of the algorithm
EDIT: Handling multiple circles intersecting is also easy. All you need to do then is instead of calculating the shortest for 1 circle you calculate for all the circles where the point lies and then find the min distance
Algorithm:
1) For each circle choose 'n' safe points. These 'n' points will form n - 1 sectors in the circle.
2) Get the current location of the user ( say A) and find all the circles where this point is included.
3) For each circle where pt A lies, calculate sector in which it lies. Say it lies on sector formed by points X_i and Y_i. Calculate the distance AX_i and AY_i.
4) Choose the minimum across all distances AX_i, AY_i and show navigation instructions for those points
It doesn't matter if the markers appear visually close to each other.. You're not going to visually find the direction the computing device is going to do it. Lat/Long values have a very high order of precision anyway.

Google Maps Android API utility library: Add a circle around the marker, when marker becomes visible

I am working on Android application which makes use of Google Maps and Google Maps Android API Utility Library. By making use of the utility library I got the clustered markers. But I want to show circle around the marker, when markers become visible.
Following is the code I am using to add clustered markers:
public class ClusterMarkersFragment {
public GoogleMap map;
private ClusterManager<MarkerItem> fenceClusterManager;
public static ClusterMarkersFragment newInstance () {
ClusterMarkersFragment clusterMarkersFragment = new
ClusterMarkersFragment();
return clusterMarkersFragment;
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
super.onCreateView(inflater, container, savedInstanceState);
View view = inflater.inflate( R.layout.fragment_cluster_marker_map,
container, false );
map = ((SupportMapFragment) getChildFragmentManager()
.findFragmentById( R.id.view_map )).getMap();
map.setMyLocationEnabled(false);
fenceClusterManager = new ClusterManager<MarkerItem>(getActivity(), map);
map.setOnCameraChangeListener(fenceClusterManager);
addClusterItems(getListofLatLngPairs());
return view;
}
private List< LatLngPair > getListofLatLngPairs () {
// returns the list from database
}
private void addClusterItems(List<LatLngPair> latLngPairs) {
for (LatLngPair latLngPair : latLngPairs) {
MarkerItem markerItem = new MarkerItem(latLngPair.lat, latLngPair.lng, (int) latLngPair);
fenceClusterManager.addItem(markerItem);
}
}
}
Following are the screenshots
When Clustered
When Cluster rendered current behavior
Desired Behavior

Try this:
private void addcircleAroundMarker() {
GoogleMap mapView;
// circle settings
int radiusM = RADIUS OF CIRCLE;
double latitude = CENTER LATITUDE;
double longitude = CENTER LONGITUDE;
LatLng latLng = new LatLng(latitude,longitude);
// draw circle
// diameter
int d = 500;
Bitmap bm = Bitmap.createBitmap(d, d, Config.ARGB_8888);
Canvas c = new Canvas(bm);
Paint p = new Paint();
p.setColor(getResources().getColor(R.color.green));
c.drawCircle(d/2, d/2, d/2, p);
BitmapDescriptor bmD = BitmapDescriptorFactory.fromBitmap(bm);
mapView.addGroundOverlay(new GroundOverlayOptions().
image(bmD).
position(latLng,radiusM*2,radiusM*2).
transparency(0.4f));
}

Display ImagesViews with animation issue

I want to display ImageViews in GridView using animation. I can display them and apply animation correctly.
But issue is that, if I apply animation on ImageView1 and then to ImageView2 (before animation on ImageView1 is ended) then animation on ImageView1 gets interrupted and ImageView1 is directly set to final state.
Note that I download image using ThreadPoolExecutor with 2 threads. Whenever an image is done downloading, I call addImage(image) method of below ImageAdapter which in turn adds image in GridView and GridView is refreshed to display latest set of images. And Here, while rendering, new image is displayed with animation and this animation(I guess) interrupts animation of currently animating images.
ImageAdapter :
public class ImageAdapter extends BaseAdapter {
private Context mContext;
private List<Bitmap> images;
private ArrayList<Integer> colors;
private boolean[] alreadyLoadedIndexes;
Animation animation;
AnimatorSet animator;
public void addImage(Bitmap img) {
images.add(img);
notifyDataSetChanged();
}
public void setAnimation(Animation animation) {
this.animator = null;
this.animation = animation;
}
public void setAnimator(AnimatorSet animation) {
this.animation = null;
this.animator = animation;
}
public void resetImages() {
images.clear();
notifyDataSetChanged();
alreadyLoadedIndexes = null;
alreadyLoadedIndexes = new boolean[20];
}
// Constructor
public ImageAdapter(Context c) {
mContext = c;
images = new ArrayList<Bitmap>();
colors = new ArrayList<Integer>();
colors.add(Color.CYAN);
colors.add(Color.BLUE);
colors.add(Color.GRAY);
colors.add(Color.YELLOW);
colors.add(Color.MAGENTA);
alreadyLoadedIndexes = new boolean[20];
}
#Override
public int getCount() {
return 20;
}
#Override
public Object getItem(int position) {
return 20;
}
#Override
public long getItemId(int position) {
return 0;
}
#Override
public View getView(int position, View convertView, ViewGroup parent) {
ImageView imageView = new ImageView(mContext);
imageView
.setBackgroundColor(colors.get((int) ((Math.sqrt(position) + 2 * position) % 5)));
// If image at index 'position' is available
if (images.size() > position) {
// If loading this image first time then only apply animation
if (!alreadyLoadedIndexes[position]) {
// If animation is specified
if (this.animation != null) {
imageView.setImageBitmap(images.get(position));
imageView.startAnimation(animation);
}
// If animator set is specified
else if (this.animator != null) {
imageView.setImageBitmap(null);
imageView.setBackgroundColor(colors.get((int) ((Math
.sqrt(position) + 2 * position) % 5)));
animator.setTarget(imageView);
animator.start();
Log.e("", "setting image after " + animator.getDuration()
/ 2);
new Handler().postDelayed(
new runnable(imageView, images.get(position)), 500);
} else {
// Use default animation if nothing is specified.
imageView.setImageBitmap(images.get(position));
animation = AnimationUtils.loadAnimation(mContext,
R.anim.fade_in);
imageView.startAnimation(animation);
}
} else {
imageView.setImageBitmap(images.get(position));
}
alreadyLoadedIndexes[position] = true;
}
imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
imageView.setLayoutParams(new GridView.LayoutParams(150, 150));
return imageView;
}
class runnable implements Runnable {
ImageView image;
Bitmap bitmap;
public runnable(ImageView img, Bitmap bitmap) {
this.image = img;
this.bitmap = bitmap;
}
#Override
public void run() {
Log.e("", "setting image.");
image.setImageBitmap(bitmap);
}
}
}

try layout animation controlor for GridView, it will animate the views item by item with respect to time duration. check this link ,

Have you tried to apply the animation outside adapter getView method like:
mGridView.getChildAt(childIndexNeededToAnimate).startAnimation(animation);
These child views are independent and not being recycled anymore since they are already drawn.

You have some alternative.
First you can use Animation in your adapter class if you don't want to change your code.
For that check this.
In your adapter class inside the getView you have to call animation like this ,
Animation animation = null;
animation = AnimationUtils.loadAnimation(context, R.anim.push_left_in);
animation.setDuration(500);
convertView.startAnimation(animation);
return convertView;
Second you should use GridLayoutAnimationController in which A layout animation controller is used to animated a grid layout's children.
Sample 1
Sample 2

Just a guess. I'm neither sure if it will help nor if I read your code right. I suppose the problem is harder than I guess.
However, you are using the same animation object for every item. Maybe you should create a new animation for each item. This could be the reason why your animation stops when you launch a new one because the new call just reuse and restarts it.
Good luck.

You problem is notifyDataSetChanged(); it interrupt the animation. Try calling it when the animation is finished.

onMarkerClick using switch Case

Marker class if final so you can't extend it and add your own attributes. You will have to handle this using your own logic.
You can do this in two ways.
You already have a Data list with all marker data.
1) You could try to set "snippet" attribute of Marker with your array index of Data array and on onMarkerClick you can get Snippet change it back to int and that would be your Data Array's index. So you can get that your clicked Marker and it's Data object and do whatever you want to do.
2) Use HashMap.
It will look something like this
HashMap<Marker, Integer> hashMap = new HashMap<Marker, Integer>();
