here's how handle immediate problem:

code method on activity/fragment starts animation 2 lines. set 2 identical onclicklisteners, 1 on each image, call animation method.

what i'm more concerned use of threads animation. not android way. should use animator make visual change view. code simple as:

        float pct = ... // ratio of votes total votes, 0.0 1.0          vone.setscalex(0f);         vone.animate().setduration(150).scalexby(pct).start();

please @ of animation tutorials on android developers site , elsewhere on web.

Android volley - avoid multiple requests of the same kind to the server? -

-
i using volley upload list of images server. happens within service. once image uploaded remove list. problem arises when internet connection breaks. when internet connection breaks , comes again thinking of adding images yet uploaded request queue. this can result in more 1 copy of same image saved on server request same image might have gone through before getting rseponse. how can address scenario? i'm not quite sure why you're using service schedule requests volley automatically runs it's request in seperate thread. nevertheless can listen both request results, successful , unsuccessful adding listeners. you can remove image list schedule request using volley. if succeeds can carry on desired, if fails can add again list. public static request getimageuploadrequest(final string image) { response.listener<t> responselistener = new response.listener<t>() { @override public void onresponse(t response...
