I  ve been working in Kotlin  recommend to everyone   so the syntax might be a bit off  What I do is to simply to call  v animate   alpha 0f  duration   200  I think that  in Java  it would be the following   v animate   alpha 0f  setDuration 200    Try  private void hide View v  int duration        v animate   alpha 0f  setDuration duration      private void show View v  int duration        v animate   alpha 1f  setDuration duration

Here is my solution   It uses AnimatorSet   AnimationSet library was too buggy to get working   This provides seamless and infinite transitions between fade in and out   public static void setAlphaAnimation View v        ObjectAnimator fadeOut   ObjectAnimator ofFloat v   alpha    1f   3f       fadeOut setDuration 2000       ObjectAnimator fadeIn   ObjectAnimator ofFloat v   alpha    3f  1f       fadeIn setDuration 2000        final AnimatorSet mAnimationSet   new AnimatorSet         mAnimationSet play fadeIn  after fadeOut        mAnimationSet addListener new AnimatorListenerAdapter              Override         public void onAnimationEnd Animator animation                super onAnimationEnd animation               mAnimationSet start                          mAnimationSet start

we can simply use   public void animStart View view        if count  0           Log d  count   String valueOf count            i1 animate   alpha 0f  setDuration 2000           i2 animate   alpha 1f  setDuration 2000           count  1            else if count  1           Log d  count   String valueOf count            count  0          i2 animate   alpha 0f  setDuration 2000           i1 animate   alpha 1f  setDuration 2000             where i1 and i2 are defined in the onCreateView   as       i1    ImageView findViewById R id firstImage       i2    ImageView findViewById R id secondImage     count is a class variable initilaized to 0   The XML file is         lt  xml version  1 0  encoding  utf-8   gt       lt RelativeLayout xmlns android  http   schemas android com apk res android          xmlns app  http   schemas android com apk res-auto          xmlns tools  http   schemas android com tools          android layout width  match parent          android layout height  match parent          tools context   MainActivity  gt           lt ImageView             android id    id secondImage              android layout width  match parent              android layout height  wrap content              android onClick  animStart              android src   drawable second    gt         lt ImageView           android id    id firstImage            android layout width  match parent            android layout height  wrap content             android onClick  animStart            android src   drawable first    gt       lt  RelativeLayout gt     drawable first and  drawable second are the images in the drawable folder in res

According to the documentation  AnimationSet     Represents a group of Animations that should be played together  The   transformation of each individual animation are composed together into   a single transform  If AnimationSet sets any properties that its   children also set  for example  duration or fillBefore   the values of   AnimationSet override the child values   AnimationSet mAnimationSet   new AnimationSet false     false means don t share interpolators      Pass true if all of the animations in this set should use the   interpolator associated with this AnimationSet  Pass false if each   animation should use its own interpolator    ImageView imageView   ImageView findViewById R id imageView   Animation fadeInAnimation   AnimationUtils loadAnimation this  R anim fade in   Animation fadeOutAnimation   AnimationUtils loadAnimation this  R anim fade out   mAnimationSet addAnimation fadeInAnimation   mAnimationSet addAnimation fadeOutAnimation   imageView startAnimation mAnimationSet     I hope this will help you

You can do this also in kotlin like this      contentView apply              Set the content view to 0  opacity but visible  so that it is visible             but fully transparent  during the animation          alpha   0f         visibility   View VISIBLE             Animate the content view to 100  opacity  and clear any animation            listener set on the view          animate                    alpha 1f                   setDuration resources getInteger android R integer config mediumAnimTime  toLong                     setListener null         read more about this in android docs
