android - Place markers on map with timer -


i'm adding markers (around 200) path on map using google maps v2, , placed on map. requirement add each marker time interval wanted animation. i've tried 2 methods, first method is

latvalues[] = {....}; longvalues[]={....}; for(int i=0;i<latvalues.length;i++){    map.addmarker(new markeroptions().position(new latlng(latvalues[i],longvalues[i])).title("info")                                         .icon(bitmapdescriptorfactory.fromresource(r.drawable.img))); thread.sleep(500); }

this not working, after placing markers, map loading..

second method is

 latvalues[] = {....}; longvalues[]={....}; timer marktimer = new timer(); marktimer.scheduleatfixedrate(new timertask() {      @override     public void run() {      for(int i=0;i<latvalues.length;i++){    map.addmarker(new markeroptions().position(new latlng(latvalues[i],longvalues[i])).title("info")                                         .icon(bitmapdescriptorfactory.fromresource(r.drawable.img)));     } } },0, 500);  marktimer.cancel();

this not loading markers also...

please suggest workaround achieve this...

edited code using countdown timer:

protected void oncreate(bundle savedinstancestate) {     super.oncreate(savedinstancestate);     setcontentview(r.layout.datemap);      supportmapfragment fm = (supportmapfragment)getsupportfragmentmanager().findfragmentbyid(r.id.busmap);     map=fm.getmap();     map.setmylocationenabled(true);      countdown(); } public void countdown(){     if(this.ctimer != null){         this.ctimer.cancel();     }     this.ctimer = new countdowntimer(1000,500) {          @override         public void ontick(long millisuntilfinished) {             // todo auto-generated method stub             if(markerno<latitudevalues1.length){                 map.addmarker(new markeroptions().position(new latlng(latitudevalues1[markerno],longitudevalues1[markerno])).title("info")                         .icon(bitmapdescriptorfactory.fromresource(r.drawable.arrow)));                 markerno++;             }         }          @override         public void onfinish() {             // todo auto-generated method stub             map.movecamera(cameraupdatefactory.newlatlngzoom(new latlng(latitudevalues1[markerno],longitudevalues1[markerno]), 12));         }     }.start(); }

have tried countdowntimer?

int markerno = 0; public void startcountdown(){            if(this._countdowntimer != null){         this._countdowntimer.cancel();     }     this._countdowntimer = new countdowntimer(time_for_set_in_s * 1000, 500){          @override         public void onfinish() {          }          @override         public void ontick(long millisuntilfinished) {                             if(markerno < longvalues.size()){                              map.addmarker(new markeroptions().position(new latlng(latvalues[markerno],longvalues[markerno])).title("info")                                     .icon(bitmapdescriptorfactory.fromresource(r.drawable.img)));                               markerno++                             }          }      }.start(); }
