Fade in not working but fade out Animation works on Android -

-

i use method show view need fade in or fade out animation.

it works when pass false execute fade out animation when pass true, fade in doesn't execute, instead, appears after 500ms without animation;

private void setviewtransition(final boolean isvisible, final view view) {      animation fadeanim;      if (isvisible) {         fadeanim = new alphaanimation(0.0f, 1.0f);         if (view.getalpha() == 1.0f) {             return;         }     } else {         fadeanim = new alphaanimation(1.0f, 0.0f);         if (view.getalpha() == 0.0f) {             return;         }     }      fadeanim.setduration(500);     fadeanim.setanimationlistener(new animation.animationlistener() {         @override         public void onanimationstart(animation animation) {         }          @override         public void onanimationend(animation animation) {             if (isvisible) {                 view.setalpha(1.0f);             } else {                 view.setalpha(0.0f);             }         }          @override         public void onanimationrepeat(animation animation) {         }     });      view.startanimation(fadeanim); }

it might related issue: android fade in not working never got answers...

what doing wrong ?

although i'm not entirely sure why way doesn't work. bit roundabout , more complicated needs to fade animation. here's concise way of doing instead (for api 12+).

private void setviewtransition(boolean isvisible, view view) {     view.animate().alpha(isvisible ? 1.0f : 0.0f).setduration(500); }
