How to generate an image number of times in android -

i have image rotates on screen. problem is, want generate image again , again on screen, after 10 seconds. tried lot using loop. not working. want generate same rotating image again , again on screen. please help. in advance. here code.

@override public void ondraw(canvas canvas) {     // todo auto-generated method stub     super.ondraw(canvas);      int draw_x = math.round(system.currenttimemillis()             % (this.getwidth() * 2));     int draw_y = math.round(system.currenttimemillis()             % (this.getheight() * 2));      (int = 0; < 10; i++) {          if (draw_x > this.getwidth())             draw_x = (this.getwidth() * (2)) - draw_x;         if (draw_y > this.getheight())             draw_y = (this.getheight() * (2)) - draw_y;         if (draw_x > this.getwidth())             draw_x = (this.getwidth() * (2)) - draw_x;         if (draw_y > this.getheight())             draw_y = (this.getheight() * (2)) - draw_y;          canvas.drawbitmap(eball, draw_x, draw_y, null);         image.add(eball);            float time = system.currenttimemillis();                       while ((time+50000)>system.currenttimemillis());          i++;         invalidate();     }  } 

busy loop definitely bad idea. never that. should use android animation framework , rotate view or use handler() , post delayed runnable:

handler h = new handler();  ....  protected runnable mtick = new runnable() {    @override    public void run() {        methodthatrotatestheimage();         h.postdelayed( this, delayinmillis );    } } 

and start do:

h.post( mtick ); 

and stop:

h.removecallbacks( mtick );
