android - How to animate an Icon in markerOptions? [GoogleMaps API] -

is there way how animate icon? need apply "wave" animation custom drawable marker on google map. suggestions welcomed!

note.: plan run handler worker thread call "seticon" method , animate icon.

desired effect:

my icon drawable:

xml:

<shape     xmlns:android="http://schemas.android.com/apk/res/android"     android:shape="oval">     <solid         android:color="#0093e8"/>     <size         android:width="120dp"         android:height="120dp"/> </shape> 

this onmapready method:

@override     public void onmapready(googlemap googlemap) {         mmap = googlemap;          mdotmarkerbitmap = generatebitmapfromdrawable();         markeroptions = new markeroptions()                 .position(xdesign)                 .title("xdesign in edinburgh")                 .icon(bitmapdescriptorfactory.frombitmap(mdotmarkerbitmap));         mxdesignmarker = mmap.addmarker(markeroptions);           bitmapdescriptor bitmapdescriptor = markeroptions.geticon();           animation fadeout = new alphaanimation(1, 0);         fadeout.setduration(1000);         animationset animation = new animationset(true);         animation.addanimation(fadeout);          //   icons dont have animate method     icon.setanimation(animation);          mmap.movecamera(cameraupdatefactory.newlatlngzoom(xdesign, 15));     } 

my generatebitmapfromdrawable method:

private bitmap generatebitmapfromdrawable() {     int px = getresources().getdimensionpixelsize(r.dimen.map_dot_marker_size);     bitmap mdotmarkerbitmap = bitmap.createbitmap(px, px, bitmap.config.argb_8888);     canvas canvas = new canvas(mdotmarkerbitmap);     drawable shape = getresources().getdrawable(r.drawable.circle_drawable);     shape.setbounds(0, 0, mdotmarkerbitmap.getwidth(), mdotmarkerbitmap.getheight());     shape.draw(canvas);     return mdotmarkerbitmap; } 

what did used custom animation class:

public class radiusanimation extends animation {     private groundoverlay groundoverlay;     private final int startingsize = 100;      public radiusanimation(groundoverlay groundoverlay) {         this.groundoverlay = groundoverlay;      }      @override     protected void applytransformation(float interpolatedtime, transformation t) {         groundoverlay.setdimensions((startingsize * interpolatedtime));         groundoverlay.settransparency(interpolatedtime);      }       @override     public void initialize(int width, int height, int parentwidth, int parentheight) {         super.initialize(width, height, parentwidth, parentheight);     } } 

and in mapfragment:

public class mapfragment extends fragment implements onmapreadycallback {      private radiusanimation groundanimation;     private animationset breadinganimations;      @override     public void onviewcreated(view view, @nullable bundle savedinstancestate) {         super.onviewcreated(view, savedinstancestate);         ripplebackground = new ripplebackground(getactivity());         ripplebackground.setbackgroundcolor(contextcompat.getcolor(getactivity(),                 r.color.pulsemarker1));          mapfragment = (supportmapfragment) getchildfragmentmanager().findfragmentbyid(r.id.map);         mapfragment.getmapasync(this);          breadinganimations = new animationset(false);     }  @override     public void onmapready(googlemap googlemap) {         mmap = googlemap; //add smallest image drawable overlay          bitmap mdotmarkerbitmap1 = generatebitmapfromdrawable(r.drawable.circle_drawable);          final int widthone = 80;         final int animationdurationone = 1200;          groundoverlay groundoverlay1 = mmap.addgroundoverlay(new groundoverlayoptions()                 .image(bitmapdescriptorfactory.frombitmap(mdotmarkerbitmap1))                 .position(xdesign, widthone));          groundanimation = new radiusanimation(groundoverlay1);         groundanimation.setrepeatcount(animation.infinite);         groundanimation.setrepeatmode(animation.restart);          groundanimation.setduration(animationdurationone); //        groundanimation.setstartoffset(700);         breadinganimations.addanimation(groundanimation);           bitmap mdotmarkerbitmap2 = generatebitmapfromdrawable(r.drawable.circle_drawable2);         final int widthtwo = 200;         final int animationdurationtwo = 2000;         groundoverlay groundoverlay2 = mmap.addgroundoverlay(new groundoverlayoptions()                 .image(bitmapdescriptorfactory.frombitmap(mdotmarkerbitmap2))                 .position(xdesign, widthtwo));          animation groundanimation2 = new radiusanimation(groundoverlay2);         groundanimation2.setrepeatcount(animation.infinite);         groundanimation2.setrepeatmode(animation.restart);         groundanimation2.setduration(animationdurationtwo); //        groundanimation2.setstartoffset(1500);         breadinganimations.addanimation(groundanimation2);           bitmap mdotmarkerbitmap3 = generatebitmapfromdrawable(r.drawable.circle_drawable3);         final int widththree = 300;         final int animationdurationthree = 3000;         groundoverlay groundoverlay3 = mmap.addgroundoverlay(new groundoverlayoptions()                 .image(bitmapdescriptorfactory.frombitmap(mdotmarkerbitmap3))                 .position(xdesign, widththree));          animation groundanimation3 = new radiusanimation(groundoverlay3);         groundanimation3.setrepeatcount(animation.infinite);         groundanimation3.setrepeatmode(animation.restart); //        groundanimation3.setstartoffset(500);         groundanimation3.setduration(animationdurationthree);          breadinganimations.addanimation(groundanimation3);          mapfragment.getview().startanimation(breadinganimations); // start animation           mmap.movecamera(cameraupdatefactory.newlatlngzoom(xdesign, zoomleval));     }      private void logthis(string message) {         log.d(tag, message);     }      @nonnull     private bitmap generatebitmapfromdrawable(int drawablesres) {         int px = getresources().getdimensionpixelsize(r.dimen.map_dot_marker_size);         bitmap mdotmarkerbitmap = bitmap.createbitmap(px, px, bitmap.config.argb_8888);         canvas canvas = new canvas(mdotmarkerbitmap);         drawable shape = getresources().getdrawable(drawablesres);         shape.setbounds(0, 0, mdotmarkerbitmap.getwidth(), mdotmarkerbitmap.getheight());         shape.draw(canvas);         return mdotmarkerbitmap;     }   }
