android - ValueAnimator duplicate Values when starting -

-

im using valueanimator (from nineoldandroids) animate view in viewgroup.

valueanimator anim = valueanimator.ofint(mhandlerect.left, mdisplayrect.right - mhandlewidth); anim.setduration(delta); anim.addupdatelistener(onanimationupdatelistener);                   anim.addlistener(onanimationlistener); anim.start();

in case 0 402, have tried other values.

then i'm using values in animation update listener:

@override         public void onanimationupdate(valueanimator animation) {             int val = (integer) animation.getanimatedvalue();              log.d("animation animating", " current value " + val); }

now, here comes problem:

the first values 0, multiple times

04-06 22:24:40.128: d/animation animating(22500):  current value 0 04-06 22:24:40.128: d/animation animating(22500):  current value 0 04-06 22:24:40.313: d/animation animating(22500):  current value 0 04-06 22:24:40.313: d/animation animating(22500):  current value 0 04-06 22:24:40.323: d/animation animating(22500):  current value 0 04-06 22:24:40.338: d/animation animating(22500):  current value 4 04-06 22:24:40.418: d/animation animating(22500):  current value 66 04-06 22:24:40.448: d/animation animating(22500):  current value 104 04-06 22:24:40.463: d/animation animating(22500):  current value 128 04-06 22:24:40.478: d/animation animating(22500):  current value 152 04-06 22:24:40.493: d/animation animating(22500):  current value 175 04-06 22:24:40.513: d/animation animating(22500):  current value 201 04-06 22:24:40.533: d/animation animating(22500):  current value 232 04-06 22:24:40.548: d/animation animating(22500):  current value 255 04-06 22:24:40.563: d/animation animating(22500):  current value 280 04-06 22:24:40.603: d/animation animating(22500):  current value 335 04-06 22:24:40.628: d/animation animating(22500):  current value 360 04-06 22:24:40.653: d/animation animating(22500):  current value 378 04-06 22:24:40.668: d/animation animating(22500):  current value 389 04-06 22:24:40.698: d/animation animating(22500):  current value 400 04-06 22:24:40.713: d/animation animating(22500):  current value 402

this results in delayed , juddery start of visible animation.

i have tried expand duration , values, problem still exists.

have same problem, or nit-pick?

i've run similar issue, in case updated value varying between start value , end value.

try this:

   int mprevious = -1;     @override             public void onanimationupdate(valueanimator animation) {                 int val = (integer) animation.getanimatedvalue();                 if(val != mprevious){                 log.d("animation animating", " current value " + val);                                     mprevious = val;                 }       }

logic statement should not have performance or visual hits.

alternatively try add 0 delayed time. make animator start animating immediately.
