Android adding simple animations while setvisibility view Gone

Question

I have designed a simple layout I have finished the design without animation  but now I want to add animations when textview click event and I don t know how to use it  Did my xml design looks good or not  Any suggestions would be appreciated   My XML   lt  xml version  1 0  encoding  UTF-8   gt   lt LinearLayout xmlns android  http   schemas android com apk res android      android layout width

Find the below code to make visible the view in Circuler reveal  if you send true  it ll get Invisible Gone  If you send false  it ll get visible  anyView is the view you re going to visible hide  it could be any view  Layouts  Buttons etc   private fun toggle flag  Boolean  anyView  View        if  flag            val cx   anyView width   2         val cy   anyView height   2         val initialRadius   Math hypot cx toDouble    cy toDouble    toFloat           val anim   ViewAnimationUtils createCircularReveal anyView  cx  cy  initialRadius  0f          anim addListener object   AnimatorListenerAdapter                 override fun onAnimationEnd animation  Animator                    super onAnimationEnd animation                  anyView visibility   View INVISIBLE                                  anim start         else           val cx   anyView width   2         val cy   anyView height   2         val finalRadius   Math hypot cx toDouble    cy toDouble    toFloat           val anim   ViewAnimationUtils createCircularReveal anyView  cx  cy  0f  finalRadius          anyView visibility   View VISIBLE         anim start

Please check this link  Which will allow animations like L2R  R2L  T2B  B2T animations   This code shows animation from left to right  TranslateAnimation animate   new TranslateAnimation 0 view getWidth   0 0   animate setDuration 500   animate setFillAfter true   view startAnimation animate   view setVisibility View GONE     if you want to do it from R2L then use   TranslateAnimation animate   new TranslateAnimation 0 -view getWidth   0 0     for top to bottom as  TranslateAnimation animate   new TranslateAnimation 0 0 0 view getHeight       and vice a versa

Based on the answer of  Xaver Kapeller I figured out a way to create scroll animation when new views appear on the screen  and also animation to hide them    It goes from this state    Button Last Button   to    Button Button 1 Button 2 Button 3 Button 4 Last Button   and viceversa   So  when the user clicks on the first button  the elements  Button 1    Button 2    Button 3  and  Button 4  will appear using fade animation and the element  Last Button  will move down till end  The height of the layout will change as well  allowing using scroll view properly   This is the code to show elements with animation   private void showElements            Precondition     if  areElementsVisible              Log w TAG   The view is already visible  Nothing to do here            return                Animate the hidden linear layout as visible and set        the alpha as 0 0  Otherwise the animation won t be shown     mHiddenLinearLayout setVisibility View VISIBLE       mHiddenLinearLayout setAlpha 0 0f       mHiddenLinearLayout              animate                setDuration ANIMATION TRANSITION TIME               alpha 1 0f               setListener new AnimatorListenerAdapter                      Override                 public void onAnimationEnd Animator animation                        super onAnimationEnd animation                       updateShowElementsButton                        mHiddenLinearLayout animate   setListener null                                               mLastButton              animate                setDuration ANIMATION TRANSITION TIME               translationY mHiddenLinearLayoutHeight           Update the high of all the elements relativeLayout     LayoutParams layoutParams   mAllElementsRelativeLayout getLayoutParams            TODO  Add vertical margins     layoutParams height   mLastButton getHeight     mHiddenLinearLayoutHeight      and this is the code to hide elements of the animation   private void hideElements            Precondition     if   areElementsVisible              Log w TAG   The view is already non-visible  Nothing to do here            return                Animate the hidden linear layout as visible and set     mHiddenLinearLayout              animate                setDuration ANIMATION TRANSITION TIME               alpha 0 0f               setListener new AnimatorListenerAdapter                      Override                 public void onAnimationEnd Animator animation                        Log v TAG   Animation ended  Set the view as gone                        super onAnimationEnd animation                       mHiddenLinearLayout setVisibility View GONE                          Hack  Remove the listener  So it won t be executed when                        any other animation on this view is executed                     mHiddenLinearLayout animate   setListener null                       updateShowElementsButton                                                mLastButton              animate                setDuration ANIMATION TRANSITION TIME               translationY 0           Update the high of all the elements relativeLayout     LayoutParams layoutParams   mAllElementsRelativeLayout getLayoutParams            TODO  Add vertical margins     layoutParams height   mLastButton getHeight        Note there is a simple hack on the method to hide the animation  On the animation listener mHiddenLinearLayout  I had to remove the listener itself by using    mHiddenLinearLayout animate   setListener null     This is because once an animation listener is attached to an view  the next time when any animation is executed in this view  the listener will be executed as well  This might be a bug in the animation listener   The source code of the project is on GitHub  https   github com jiahaoliuliu ViewsAnimated  Happy coding   Update  For any listener attached to the views  it should be removed after the animation ends  This is done by using  view animate   setListener null

You can do two things to add animations  first you can let android animate layout changes for you  That way every time you change something in the layout like changing view visibility or view positions android will automatically create fade transition animations  To use that set   android animateLayoutChanges  true    on the root node in your layout   Your second option would be to manually add animations  For this I suggest you use the new animation API introduced in Android 3 0  Honeycomb   I can give you a few examples   This fades out a View   view animate   alpha 0 0f     This fades it back in   view animate   alpha 1 0f     This moves a View down by its height   view animate   translationY view getHeight       This returns the View to its starting position after it has been moved somewhere else   view animate   translationY 0     You can also use setDuration   to set the duration of the animation  For example this fades out a View over a period of 2 seconds   view animate   alpha 0 0f  setDuration 2000     And you can combine as many animations as you like  for example this fades out a View and moves it down at the same time over a period of 0 3 seconds   view animate            translationY view getHeight             alpha 0 0f           setDuration 300     And you can also assign a listener to the animation and react to all kinds of events  Like when the animation starts  when it ends or repeats etc  By using the abstract class AnimatorListenerAdapter you don t have to implement all callbacks of AnimatorListener at once but only those you need  This makes the code more readable  For example the following code fades out a View moves it down by its height over a period of 0 3 seconds  300 milliseconds  and when the animation is done its visibility is set to View GONE   view animate            translationY view getHeight             alpha 0 0f           setDuration 300           setListener new AnimatorListenerAdapter                  Override             public void onAnimationEnd Animator animation                    super onAnimationEnd animation                   view setVisibility View GONE

Try adding this line to the xml parent layout    android animateLayoutChanges  true    Your layout will look like this   lt  xml version  1 0  encoding  UTF-8   gt   lt LinearLayout xmlns android  http   schemas android com apk res android      android layout width  match parent      android layout height  match parent      android animateLayoutChanges  true      android longClickable  false      android orientation  vertical      android weightSum  16  gt              other code here       lt  LinearLayout gt

The easiest way to animate Visibility changes is use Transition API which available in support  androidx  package  Just call TransitionManager beginDelayedTransition method then change visibility of the view  There are several default transitions like Fade  Slide    import androidx transition TransitionManager  import androidx transition Transition  import androidx transition Fade   private void toggle         Transition transition   new Fade        transition setDuration 600       transition addTarget R id image        TransitionManager beginDelayedTransition parent  transition       image setVisibility show   View VISIBLE   View GONE       Where parent is parent ViewGroup of animated view  Result     Here is result with Slide transition   import androidx transition Slide   Transition transition   new Slide Gravity BOTTOM       It is easy to write custom transition if you need something different  Here is example with CircularRevealTransition which I wrote in another answer  It shows and hide view with CircularReveal animation   Transition transition   new CircularRevealTransition        android animateLayoutChanges  true  option does same thing  it just uses AutoTransition as transition
