Android Animation Does Not Repeat

Android animation does not repeat

Update: Back in Sep, 2011 an Android engineer fixed this issue for the most part. The attributes that were ignored in XML now work, with the exception of repeatCount and fillEnabled which are still ignored (on purpose for some reason). This means it still isn't easy to repeat an AnimationSet unfortunately.

For details please see the overview in the updated docs (explains which attributes are ignored, which work, and which are passed onto children). And for a deeper understanding of what fillAfter, fillBefore, and fillEnabled actually do, see the engineer's (Chet Haase) blog post about it here.

Original Answer

To expand upon answers by Pavel and others: it is true that the <set> tag is ridiculously buggy. It can't deal correctly with repeatCount and a number of other attributes.

I spent a few hours figuring out what it can and can't deal with and have submitted a bug report/issue here: Issue 17662

In summary (this concerns AnimationSets):

setRepeatCount() / android:repeatCount

This attribute (as well as repeatMode) does not work in code or XML. This makes repeating an entire set of animations difficult.

setDuration() / android:duration

Setting this on an AnimationSet in code WORKS (overrides all durations of children animations), but not when included in the tag in XML

setFillAfter() / android:fillAfter

This works in both code and XML for the tag. Strangely I have gotten it to also work without the need to set fillEnabled to true.

setFillBefore() / android:fillBefore

Seems to have no effect/ignored in both code and XML

setFillEnabled() / android:fillEnabled

Seems to have no effect/ignored in both code and XML. I can still get fillAfter to work even without including fillEnabled or setting fillEnabled to false.

setStartOffset() / android:startOffset

This works only in code and not XML.

Android Animation doesn't repeat

this code works for me

        RotateAnimation rotate = new RotateAnimation(0, 360, Animation.RELATIVE_TO_SELF,
            0.5f,  Animation.RELATIVE_TO_SELF, 0.5f);
    rotate.setRepeatCount(Animation.INFINITE);
    rotate.setRepeatMode(Animation.INFINITE);
    rotate.setDuration(500);
    imageView.startAnimation(rotate);

Android TextView Animation Infinite Repeat Not Working

Try this in the XML code. The java code did not work and I solved it well with this. Just apply this in your code:

<set xmlns:android="http://schemas.android.com/apk/res/android"
    android:shareInterpolator="false" >

    <rotate
        android:fromDegrees="0"
        android:pivotX="50%"
        android:pivotY="50%"
        android:toDegrees="360"
        android:duration="1000"
        android:repeatCount="infinite"
        android:repeatMode="restart"/>

</set>

Add the last two lines of <rotate> inside your code. In your case, inside the two components <translate> and remove the equivalent Java code:

animation.setRepeatMode(Animation.INFINITE);
animation.setRepeatCount(Animation.INFINITE);

This code will make an object rotate on itself indefinitely, if someone serves.

Good Luck!!

Repeat android animation

Like this.

animation.setRepeatCount(Animation.INFINITE);

How to repeat an android xml animation

In your question, you are setting mode as count and count as mode.

setRepeatCount(Animation.INFINITE); 
setRepeatMode(Animation.RESTART);
// or setRepeatMode(Animation.REVERSE);

EDIT:

It seems that there's some confusion here. You are creating AnimationSet and not Animation. Unfortunately, AnimationSet does not seem to support repetition as well as Animation.

So you'd need to call animationSet.start() in onAnimationEnd callback. For further details, check this answer. How to repeat an AnimationSet with sequentially added animations

In onAnimationEnd calling view.startAnimation(animationSet) seems to work as well.

How to repeat Android Animation

You can run multiple SpringAnimations on the same View by repeatedly calling animateToFinalPosition(translation) with a sequence of translation values.

For example:

startSpringAnimations(findViewById<View>(R.id.imageView1), 300f, 6)
startSpringAnimations(findViewById<View>(R.id.imageView2), -600f, 6)

with a function

/**
 * [view] will be moved using [times] SpringAnimations over a distance of abs([totalTranslation])
 * If [totalTranslation] is negative, direction will be up, else down
 */
private fun startSpringAnimations(view: View, totalTranslation: Float, times: Int ) {
    if(times <= 0){
        return
    }

    val translation = totalTranslation/ times.toFloat()

    SpringAnimation(view, DynamicAnimation.TRANSLATION_Y, 0f).apply{
        spring.dampingRatio = SpringForce.DAMPING_RATIO_HIGH_BOUNCY
        spring.stiffness = SpringForce.STIFFNESS_VERY_LOW

        addEndListener(object: DynamicAnimation.OnAnimationEndListener{
            private var count = 1
            override fun onAnimationEnd(animation1: DynamicAnimation<*>?, canceled: Boolean, value: Float, velocity: Float) {
                Log.d("SpringAnimation", "onAnimationEnd: animation $animation1 canceled $canceled value $value velocity $velocity count $count")
                if (canceled) return

                count++
                if(count <= times){
                    animateToFinalPosition(translation * count)
                }
            }
        })
        animateToFinalPosition(translation)
    }
}

Why my animation doesn't repeat?

Change your XML to have the repeat mode and count on it:

<set xmlns:android="http://schemas.android.com/apk/res/android"
     android:shareInterpolator="false">
  <translate android:fromXDelta="0%" android:toXDelta="-18.5%"
             android:fromYDelta="0%" android:toYDelta="0%"
             android:repeatCount="infinite"
             android:repeatMode="restart"
             android:duration="1000"/>
</set>
