I have problem with scale in animation. Translate works fine, but when I add scale to my animation it dont come back to point of start and blink when animation starts again.
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator">
<translate
android:fromYDelta="-150"
android:toYDelta="150"
android:fillAfter="true"
android:duration="1500"
/>
<scale
android:fillAfter="true"
android:fromXScale="1"
android:fromYScale="1"
android:toXScale="1.2"
android:toYScale="1.2"
android:duration="1500"
android:pivotX="50%"
android:pivotY="50%"
/>
</set>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator">
<translate
android:fromYDelta="150"
android:toYDelta="-150"
android:fillAfter="true"
android:duration="1500"
android:startOffset="1500"
/>
<scale
android:fillAfter="true"
android:fromXScale="1.2"
android:fromYScale="1.2"
android:toXScale="1"
android:toYScale="1"
android:duration="1500"
android:pivotX="50%"
android:pivotY="50%"
android:startOffset="1500"
/>
</set>
And Android code:
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
image = (ImageView) findViewById(R.id.image);
image.setImageResource(R.drawable.shape);
animation2 = AnimationUtils.loadAnimation(this, R.anim.moving_up);
animation3 = AnimationUtils.loadAnimation(this, R.anim.moving_down);
animation = new AnimationSet(true);
animation.addAnimation(animation2);
animation.addAnimation(animation3);
animation.setAnimationListener(this);
//animation.setRepeatCount(Animation.INFINITE);
animation.setFillEnabled(true);
animation.setFillAfter(true);
image.startAnimation(this.animation);
}
#Override
public void onAnimationEnd(Animation animation) {
image.clearAnimation();
image.startAnimation(animation);
}
Shape is a xml Rect.
animation.setFillAfter(true);
will force the image to stay at animated position after animation gets completed.
Set it to false if you want to return the image to starting position.
animation.setFillAfter(false);
If someone would like to know the answer
private void animateImage(){
float x = 1;
float scale = 1.1f;
x = (imageViewImage.getHeight()*1.1f - imageViewImage.getHeight())/2;
imageViewImage.animate().translationY(x).scaleX(scale).scaleY(scale).setDuration(8000).withEndAction(new Runnable() {
#Override
public void run() {
imageViewImage.animate().translationY(0).scaleX(1f).scaleY(1f).setDuration(8000).withEndAction(new Runnable() {
#Override
public void run() {
animateImage();
}
});
}
});
}

I have anim file
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="60000"
android:fillAfter="true"
android:interpolator="#android:anim/linear_interpolator"
android:shareInterpolator="false" >
<rotate
android:startOffset="0"
android:fromDegrees="0"
android:pivotX="50%"
android:pivotY="50%"
android:toDegrees="360" />
</set>
and I want animation to start immediately. But is starts after 2-3 sec delay. What can be the reason?
Its working properly in my code. So there are no error in XML. Please check your Java. My Java code is:
void startAnim() {
view.clearAnimation();
Animation anim= AnimationUtils.loadAnimation(MainActivity.this, R.anim.anim);
view.startAnimation(anim);
}
private ImageView logo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
logo=(ImageView)findViewById(R.id.logo);
Animation myanim = AnimationUtils.loadAnimation(this,R.anim.anim);
logo.startAnimation(myanim);
}
In my application I have this animation
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true"
android:shareInterpolator="true">
<alpha
android:duration="1000"
android:startOffset="2000"
android:fromAlpha="0"
android:toAlpha="1"/>
<scale
android:duration="400"
android:startOffset="4000"
android:fromXScale="1"
android:fromYScale="1"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="0.9"
android:toYScale="0.9"/>
<scale
android:duration="400"
android:startOffset="4400"
android:fromXScale="0.9"
android:fromYScale="0.9"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="1"
android:toYScale="1"/>
<alpha
android:duration="1000"
android:startOffset="5800"
android:fromAlpha="1"
android:toAlpha="0"/>
</set>
Generally it shows image, make "press" gesture and hide it. What I want is run this animation in infinite loop. Setting parameter repeatCount doesn't work. Only way I found is to start animation again in animation listener.
final Animation pointerAnim = AnimationUtils.loadAnimation(this, R.anim.pointer);
pointerAnim.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(final Animation animation) {}
#Override
public void onAnimationEnd(final Animation animation) {
pointerView.startAnimation(pointerAnim);
}
#Override
public void onAnimationRepeat(final Animation animation) {}
});
pointerView.startAnimation(pointerAnim);
But here comes my problem. Between end and new start animation, the image "blink" (appeared and disappeared in short moment) and I don't know how to prevent this. Using fillAfter doesn't work. Also setting appropriate visibility in listener doesn't work. Note that target API is 10.
I'll be glad for any advice
This was surprisingly tricky, but here's an answer that seems to work and avoid the blinking. Break the animation up into two parts and set two animation listeners so that when each of them finish, they trigger the other one to start. It looks as follows:
pointer_fade_in.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true"
android:shareInterpolator="true">
<alpha
android:duration="1000"
android:startOffset="2000"
android:fromAlpha="0"
android:toAlpha="1"/>
<scale
android:duration="400"
android:startOffset="4000"
android:fromXScale="1"
android:fromYScale="1"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="0.9"
android:toYScale="0.9"/>
</set>
pointer_fade_out.xml
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale
android:duration="400"
android:startOffset="0"
android:fromXScale="0.9"
android:fromYScale="0.9"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="1"
android:toYScale="1"/>
<alpha
android:duration="1000"
android:startOffset="1400"
android:fromAlpha="1"
android:toAlpha="0"/>
</set>
Then the code:
final Animation pointerFadeInAnim = AnimationUtils.loadAnimation(this, R.anim.pointer_fade_in);
final Animation pointerFadeOutAnim = AnimationUtils.loadAnimation(this, R.anim.pointer_fade_out);
pointerFadeInAnim.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(final Animation animation) {}
#Override
public void onAnimationEnd(final Animation animation) {
pointerView.startAnimation(pointerFadeOutAnim);
}
#Override
public void onAnimationRepeat(final Animation animation) {}
});
pointerFadeOutAnim.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation) {
pointerView.startAnimation(pointerFadeInAnim);
}
#Override
public void onAnimationRepeat(Animation animation) {}
});
pointerView.startAnimation(pointerFadeInAnim);
Hope this works for you!
Did you try combining both repeatMode and repeatCount attributes like in the following example
<scale
android:fromXScale="0.0"
android:toXScale="1.0"
android:fromYScale="0.0"
android:toYScale="1.0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2000"
android:repeatCount="infinite"
android:repeatMode="restart"
/>
Hope it has helped
Maybe it's just a workaround that won't be applicable in your case, but would it be possible to offset the entiere animation, so that it starts at 3000 ? (Thus, when alpha=1.0)
(Well, after some thought, I'm pretty sure you can't do that, because the alpha transition should be the first when the object first appears on screen)
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true"
android:shareInterpolator="true">
<scale
android:duration="400"
android:startOffset="1000"
android:fromXScale="1"
android:fromYScale="1"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="0.9"
android:toYScale="0.9"/>
<scale
android:duration="400"
android:startOffset="1400"
android:fromXScale="0.9"
android:fromYScale="0.9"
android:pivotX="50%"
android:pivotY="50%"
android:toXScale="1"
android:toYScale="1"/>
<alpha
android:duration="1000"
android:startOffset="2800"
android:fromAlpha="1"
android:toAlpha="0"/>
<alpha
android:duration="1000"
android:startOffset="5800"
android:fromAlpha="0"
android:toAlpha="1"/>

I am trying to make a TextView grow and then shrink. This process should be repeated infinitely. How do I achieve that? My scale.xml looks like this:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
<scale
android:fromXScale="1.0"
android:fromYScale="1.0"
android:toXScale="2.0"
android:toYScale="2.0"
android:duration="1400" />
</set>
Here's my animation method:
public void runAnimation() {
Animation a = AnimationUtils.loadAnimation(this, R.anim.scale);
a.setRepeatMode(Animation.REVERSE);
a.setRepeatCount(Animation.INFINITE);
a.reset();
textView.clearAnimation();
textView.startAnimation(a);
}
Now my problem is that the TextView grows, but then immediately reverses to the starting appereance. Why won't it go reverse, shrink and repeat the process?
Try this :
public void runAnimation() {
Animation a = AnimationUtils.loadAnimation(this, R.anim.scale);
a.setRepeatMode(Animation.REVERSE);
a.setRepeatCount(-1);
textView.clearAnimation();
textView.startAnimation(a);
}
EDIT
Here is my own code that is working right now :
Call animate like animate(textView)
public void animate (View view) {
mAnimation = new ScaleAnimation(0.3f,0.5f,0.3f,0.5f,Animation.RELATIVE_TO_SELF, 0.5f, Animation.RELATIVE_TO_SELF, 0.45f);
mAnimation.setDuration(300);
mAnimation.setRepeatCount(-1);
mAnimation.setRepeatMode(Animation.REVERSE);
mAnimation.setInterpolator(new AccelerateInterpolator());
mAnimation.setAnimationListener(new Animation.AnimationListener(){
#Override
public void onAnimationStart(Animation animation) {
}
#Override
public void onAnimationEnd(Animation animation) {
}
#Override
public void onAnimationRepeat(Animation animation) {
}
});
view.setAnimation(mAnimation);
}
Try this found on some blog. Works perfect for me.
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator">
<scale
android:fromXScale="0.0"
android:toXScale="1.0"
android:fromYScale="0.0"
android:toYScale="1.0"
android:pivotX="50%"
android:pivotY="50%"
android:duration="2000" />
</set>
Here is a simple way to do so
ObjectAnimator scaleDown = ObjectAnimator.ofPropertyValuesHolder(textView,
PropertyValuesHolder.ofFloat("scaleX", 2.0f),
PropertyValuesHolder.ofFloat("scaleY", 2.0f));
scaleDown.setDuration(410);
scaleDown.setRepeatCount(ObjectAnimator.INFINITE);
scaleDown.setRepeatMode(ObjectAnimator.REVERSE);
scaleDown.start();
Hope it helps.
In your animation XML file add:
android:repeatCount="infinite"
And on your animation activity:
textmain.startAnimation(animationMainText);
animationMainText.setRepeatMode(Animation.REVERSE);
I have top_sliding_out animation defined like that:
<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android"
android:interpolator="#android:anim/linear_interpolator" >
<alpha
android:duration="300"
android:fromAlpha="1"
android:toAlpha="0" />
<scale
android:duration="300"
android:fromXScale="1"
android:fromYScale="1"
android:pivotX="50%"
android:pivotY="0%"
android:toXScale="1"
android:toYScale="0" />
</set>
Code triggering animation:
public void onCheckedChanged(final CompoundButton buttonView, boolean isChecked)
{
Animation anim = AnimationUtils.loadAnimation(this.getActivity(), R.anim.top_slide_out);
anim.setFillAfter(true);
((View)buttonView.getParent()).startAnimation(anim);
final Handler handler = new Handler();
handler.postDelayed(new Runnable()
{
public void run()
{
getListView().requestLayout();
}
}, anim.getDuration());
}
I perform this animation to hide my custom row in a list. But the problem is that layout doesn't change it's size, so it is left with empty hole.
Before animation:
After animation:
What can I do about that? How can I change layout when animation is in progress?
I am applying three animations in an ImageView, one after another. I have a AnimationListener for each animation, so inside the onAnimationEnd, I start the next one, so they dont overlap. The animations are this: scale in, fade out and the last one fade in. The fade in animation will restart the scale in animation again, to these animations will be running "forever". What I am trying to achieve is the same effect Twitter has applied to their new home screen, where they keep changing the pictures.
The problem with my animations is that after scaling in the ImageView and before staring the the fade out animation, the ImageView gets reseted and the scale change is lost, even setting fillAfter in the code or in the xml file. Here is the code for handling the animation events:
mAnimationFadeIn = AnimationUtils.loadAnimation(this, R.anim.fade_in);
mAnimationFadeIn.setFillAfter(true);
mAnimationFadeOut = AnimationUtils.loadAnimation(this, R.anim.fade_out);
mAnimationFadeOut.setFillAfter(true);
mAnimationScaleIn = AnimationUtils.loadAnimation(this, R.anim.slow_scale_in);
mAnimationScaleIn.setFillAfter(true);
mAnimationScaleIn.setFillEnabled(true);
mAnimationScaleIn.setFillBefore(false);
mAnimationScaleIn.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationRepeat(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation) {
mImageView.startAnimation(mAnimationFadeOut);
}
});
mAnimationFadeOut.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationRepeat(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation) {
mImageView.setImageResource(mImages[++mImageIndex > 2 ? mImageIndex=0 : mImageIndex]);
mImageView.startAnimation(mAnimationFadeIn);
}
});
mAnimationFadeIn.setAnimationListener(new AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {}
#Override
public void onAnimationRepeat(Animation animation) {}
#Override
public void onAnimationEnd(Animation animation) {
mImageView.startAnimation(mAnimationScaleIn);
}
});
mImageView.startAnimation(mAnimationScaleIn);
and here are my animations:
scale in:
<?xml version="1.0" encoding="utf-8"?>
<scale xmlns:android="http://schemas.android.com/apk/res/android"
android:fillAfter="true"
android:duration="9000"
android:fromXScale="1.0"
android:fromYScale="1.0"
android:interpolator="#android:anim/linear_interpolator"
android:pivotX="50.0%"
android:pivotY="50.0%"
android:toXScale="1.1"
android:toYScale="1.1" />
fade in:
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromAlpha="0.0"
android:interpolator="#android:anim/linear_interpolator"
android:toAlpha="1.0" />
fade out:
<?xml version="1.0" encoding="utf-8"?>
<alpha xmlns:android="http://schemas.android.com/apk/res/android"
android:duration="1000"
android:fromAlpha="1.0"
android:interpolator="#android:anim/linear_interpolator"
android:toAlpha="0.0" />
Is there a way to keep the scale transformation before starting the fade out animation?
I have tried all the combinations for setFillAfter, setFillBefore and setFillEnabled and no way I can get the scale transformation to be kept after the scale animation is over.
Many thanks

do as given below u have to enable it in set tag and than use in either rotate or scale etc...
