android - Andorid Google map show custom marker and clustering issue -


i show custom marker google map , cluster them. marker contains imageview shows avatar downloaded network. here target: enter image description here

everythings ok, however, when implemented google maps android marker clustering utility, imageview shows same avatar (sometime 2 wrong avatars). enter image description here
here custom markerrender:

public class markerrender extends defaultclusterrenderer<image> {     private static final string tag = markerrender.class.getsimplename();     private icongenerator clustergenerator;     private icongenerator markergenerator;     private imageview mimgmarkerthumbnail;     private imageview mimgmarkerclusterthumbnail;     private textview txtsizecluster;     private activity activity;     private bitmap mask, background;     private atomicinteger imagedownloadcounter;     private int totalitem;     private imagesize imagesize;      public markerrender(fragmentactivity activity, googlemap mmap, clustermanager<image> mclustermanager) {         super(activity, mmap, mclustermanager);         this.activity = activity;         imagedownloadcounter = new atomicinteger(0);         mask = bitmapfactory.decoderesource(activity.getresources(),                 r.drawable.annotation_behind);         background = bitmapfactory.decoderesource(activity.getresources(),                 r.drawable.annotation_behind);         setupclustericon();         setupmarker();     }      private void setupclustericon() {         clustergenerator = new icongenerator(activity);         view clusterview = activity.getlayoutinflater().inflate(r.layout.custom_marker_cluster, null);         txtsizecluster = (textview) clusterview.findviewbyid(r.id.tv_number_marker);         mimgmarkerclusterthumbnail = (imageview) clusterview.findviewbyid(r.id.img_load);         clustergenerator.setcontentview(clusterview);         clustergenerator.setbackground(null);     }      private void setupmarker() {         markergenerator = new icongenerator(activity);         view markerview = activity.getlayoutinflater().inflate(r.layout.custom_marker, null);         mimgmarkerthumbnail = (imageview) markerview.findviewbyid(r.id.img_load);         markergenerator.setcontentview(markerview);         markergenerator.setbackground(null);      }      @override     protected void onbeforeclusteritemrendered(final image image, final markeroptions markeroptions) {         initimagesizeifneed();         bitmap icon = markergenerator.makeicon();         pflogmanager.instance.loge(tag, "maken icon: " + icon.hashcode());         markeroptions.icon(bitmapdescriptorfactory.frombitmap(icon));         icon.recycle();     }      @override     protected void onclusteritemrendered(final image image, marker marker) {         super.onclusteritemrendered(image, marker);         imageloader.getinstance().loadimage(image.getmapimagelink(), imagesize,                 new simpleimageloadinglistener() {                     @override                     public void onloadingcomplete(string imageuri, view view, bitmap loadedimage) {                         bitmap croppedbitmap = helpers.makecroppedbitmap(loadedimage, background, mask);                         mimgmarkerthumbnail.setimagebitmap(croppedbitmap);                     }                 });     }      @override     protected void onbeforeclusterrendered(cluster<image> cluster, markeroptions markeroptions) {         initimagesizeifneed();         bitmap icon = clustergenerator.makeicon();         markeroptions.icon(bitmapdescriptorfactory.frombitmap(icon));         icon.recycle();     }      @override     protected void onclusterrendered(cluster<image> cluster, marker marker) {         super.onclusterrendered(cluster, marker);         arraylist<image> list = new arraylist<>(cluster.getitems());         settextnumbermarker(cluster);         string urlfirstimage = list.get(0).getmapimagelink();         imageloader.getinstance().loadimage(urlfirstimage, imagesize,                 new simpleimageloadinglistener() {                     @override                     public void onloadingcomplete(string imageuri, view view, bitmap loadedimage) {                         final bitmap croppedbitmap = helpers.makecroppedbitmap(loadedimage, background, mask);                         mimgmarkerclusterthumbnail.setimagebitmap(croppedbitmap);                     }                 });     }      private void loadclusterthumbnail(string url) {     }      private void settextnumbermarker(cluster<image> cluster) {         int size = cluster.getsize();         if (size > 99) {             txtsizecluster.settext("99+");         } else {             txtsizecluster.settext(string.valueof(cluster.getsize()));         }     }      @override     protected boolean shouldrenderascluster(cluster cluster) {         return cluster.getsize() > 1;     }  }


i've guess issue use 1 imageview show avatar, try use unique imageview each marker (by inflat new 1 xml every time needed), result show blank marker (just background , there no avatar).
took 3 days of research without results, please me!

i've resolved myself. solution use marker.seticon() method after image downloaded netword or got cache. dont use imageview anymore.
so, modified above markerrender class:
the setupclustericon() method:

private void setupclustericon() {     relativelayout.layoutparams params = new relativelayout.layoutparams(markerwidth, markerheight);     imageview marker = new imageview(activity);     marker.setlayoutparams(params);      clustergenerator = new icongenerator(activity);     clustergenerator.setcontentview(marker);     clustergenerator.setbackground(null); }


and onclusteritemrendered() method:

 protected void onclusteritemrendered(final image image, final marker marker) {         super.onclusteritemrendered(image, marker);         imageloader.getinstance().loadimage(image.getmapimagelink(), imagesize,                 new simpleimageloadinglistener() {                     @override                     public void onloadingcomplete(string imageuri, view view, bitmap loadedimage) {                         bitmap croppedbitmap = helpers.makeclusteritembitmap(background, loadedimage, mask);                         try {                             marker.seticon(bitmapdescriptorfactory.frombitmap(croppedbitmap));                         } catch (exception e) {                             e.printstacktrace();                         }                     }                 });     }


makeclusteritembitmap helper method:

   public static bitmap makeclusteritembitmap(bitmap background, bitmap original, bitmap mask) {         bitmap croppedoriginal = makecroppedbitmap(original, mask);         bitmap result = bitmap.createbitmap(background.getwidth(), background.getheight(),                 bitmap.config.argb_8888);         canvas mcanvas = new canvas(result);         croppedoriginal = bitmap.createscaledbitmap(croppedoriginal, croppedoriginal.getwidth() - 20, croppedoriginal.getheight() - 20, true);         mcanvas.drawbitmap(background, 0, 0, null);         mcanvas.drawbitmap(croppedoriginal, 10, 10, null);         return result;     }      public static bitmap makecroppedbitmap(bitmap original, bitmap mask) {         original = bitmap.createscaledbitmap(original, mask.getwidth(),                 mask.getheight(), true);         bitmap result = bitmap.createbitmap(original.getwidth(), original.getheight(),                 bitmap.config.argb_8888);         canvas mcanvas = new canvas(result);         paint paint = new paint(paint.anti_alias_flag);         paint.setxfermode(new porterduffxfermode(porterduff.mode.dst_in));         mcanvas.drawbitmap(original, 0, 0, null);         mcanvas.drawbitmap(mask, 0, 0, paint);         paint.setxfermode(null);         return result;     }


done, finish 3 nightmare researchingdays days :p
however, approach leads new issue: the performance. cause drawing new bitmap many layers, map laggy bit. i'm thinking in improving :)
any sugguestion appriciate :d

apache - PHP Soap issue while content length is larger -

we have developed soap based webservice post data third party webservice. accepts 4 params. in 1 of parameters accepts xml string no size limit restriction put in place. the webservice works fine in local environment running on php 5.2 , apache2. works content length long 10 mb. in staging server running nginx , php fpm.we have updated max post size , max upload filesize in php.ini , client_max_body param in nginx.conf allow upto 50 mb. but webservice client keeps on loading in staging environment. gives 502 timeout , gives soap error. can me understand issue here?

javascript - Complete OpenIDConnect auth when requesting via Ajax -

the normal openidconnect server works like: you go a.com/secure-resource you 302 server your browser handles , sends identity server you login there it sends a.com via post you logged in on a.com , a.com/secure-resource on browser. however have scenario i'm trying solve need help. the user logged in on idserver the user logged in on a.com the user not logged in on b.com we need send ajax call web server b.com (from domain a.com ) b.com configured use openidconnect. but because request b.com via ajax, user cannot redirected idserver. (all in response 302 ) we can go ahead , handle 302 via ajax (i'm still not sure whether work, security-wise). but is there scenario in identityserver/openidconnect designed these situations? with identityserver in scenario setup server b.com use bearer token authentication, need use access token provided a.com in headers of ajax call $.ajax({ url: 'http://b.com', headers: { ...
