the image will go back to 0,0 after animation finish
how to set not go back?
still stay in 100,100
Animation am = new TranslateAnimation((float)0(), (float)100, (float)0,(float)100);
am.setDuration(5000);
am.setRepeatCount(0);
point.startAnimation(am);
Use Animation.setFillAfter(true) to persist the final animation state.
http://developer.android.com/reference/android/view/animation/Animation.html#setFillAfter(boolean)
If fillAfter is true, the transformation that this animation performed will persist when it is finished. Defaults to false if not set. Note that this applies to individual animations and when using an AnimationSet to chain animations.
Animation am = new TranslateAnimation((float)0(), (float)100, (float)0,(float)100);
am.setDuration(5000);
am.setFillAfter(true);
am.setRepeatCount(0);
point.startAnimation(am);

Any Android phone has developer options to modify animation speed. Window animation scale, Transition animation scale, and Animator duration scale are the three settings I'm talking about.
The below code snippet ignores your settings:
.delay(200, TimeUnit.MILLISECONDS).subscribe
The code ignores animation settings because "delay" is not inherently tied to animations. In my code's case, it is.
How can I get this code in my app to scale based on the device's developer options animation scale settings?
Do not tie your code to animation using delay in milliseconds.
While this is an easy solution, the animation delay or duration, may differ from the value you set to it. Instead, you can use animation listeners callbacks.
So I found out how to get the system settings for a multiplier...
.delay(getScaledDelayDuration(200), TimeUnit.MILLISECONDS).subscribe
private long getScaledDelayDuration(long delay) {
float multiplier = Settings.System.getFloat(
this.getContext().getContentResolver(),
Settings.System.TRANSITION_ANIMATION_SCALE, 1);
return (long) (multiplier * delay);
}
...but that not only doesn't solve the root issue I'm having, it also is just not a good way to go about this at all. I'm thinking I should just delete the question at this point.
Building this app, I have managed to use some animations
using them with View view.setAnimation() etc..
This is the code i have:
// animation Properties
Animation fadeIn = new AlphaAnimation(0, 1);
fadeIn.setInterpolator(new DecelerateInterpolator()); // add this
fadeIn.setDuration(5000);
AnimationSet animation1 = new AnimationSet(false); // change to false
//animation.addAnimation(fadeIn);
animation1.addAnimation(fadeIn);
animation1.setRepeatCount(1);
Animation fadeOut = new AlphaAnimation(1, 0);
fadeOut.setInterpolator(new AccelerateInterpolator()); // and this
//fadeOut.setStartOffset(fadeInDuration + timeBetween);
fadeOut.setDuration(5000);
AnimationSet animation = new AnimationSet(false); // change to false
//animation.addAnimation(fadeIn);
animation.addAnimation(fadeOut);
animation.setRepeatCount(1);
textViewTopBannerBizName.setAnimation(animation1);
textViewTopBannerBizCategory.setAnimation(animation1);
So all, I want is that textViewTopBannerBizName and textViewTopBannerBizCategory will fade into screen as i used animation1 for both of them.
However first time when i launched the app it worked perfect but when I relaunched it again it stopped working.
It makes me wonder... why...?
Please help,
Thank you for your time.
try this.(Tested)
textViewTopBannerBizName.startAnimation(animation1);
You can clear animation if cached before by calling clearAnimation() and then startAnimation or setAnimation.
Edited
setAnimation
Sets the next animation to play for this view.But view animation does not start yet.
startAnimation
If you want the animation to play immediately, use startAnimation. This method provides allows fine-grained control over the start time and invalidation, but you must make sure that
1) the animation has a start time set,
2) the view will be invalidated when the animation is supposed to start
After setting animation, Please do invalidate the view if it's not an Activity
imb6.setAnimation(MainActivity.blinkAnimation(mContext, true))
invalidate();
I wish this'll helps.
Can one undo the changes he made on View properties using animate() on it?
In particular, how to undo changes made using animate().yBy(x)?
Note that I tried using animate().yBy(-x) and it works most of the times, but there are times that for some reason animate().yBy(x) seem not to be completed correctly (especially when the fragment pauses and then resumed) so animate().yBy(-x) is over-moving the view.
I'm looking for a way to make the View reset its properties to the way they were before I changed them using animate().
xBy() and yBy() animations affect the translationX and translationY properties. You can get the current values of those properties via getTranslationX() and getTranslationY(). So, to undo the previous animations, multiply the current property values by -1 and animate those. Or if you are seeking a "smash cut" jump (no animation), just call setTranslationX(0) or setTranslationY(0).
By using interpolator we can inverse the animation:
public class InverAnim implements Interpolator {
#Override
public float getInterpolation(float paramFloat) {
return Math.abs(paramFloat -1f);
}
}
On your animation you can set, new interpolator:
myAnimation.setInterpolator(new InverAnim());
According to the documentation http://developer.android.com/reference/android/animation/AnimatorSet.html#end() end() method should assign the end values for all animations inside the set. However ending does nothing if the set was not started. This is different from ValueAnimator i.e. which does not care and artifically starts the animation, fires onAnimationStart() event and then ends it which results in setting the end values properly.
Let me tell you why this is a problem. If you want to have the ability to update your View with and without animation (depending on the situation) you don't want to have two separate methods for it. Instead you could create an animation and start it normally or immediately set the end values. With ValueAnimator this works nicely. However AnimatorSet does not play ball and if you try to end it before calling start() it simply exits.
One workaround for this is to call start() and end() immediately after but it does not cover the situation with nested AnimatorSets like this:
AnimatorSet mainSet = new AnimatorSet();
AnimatorSet scaleSet = new AnimatorSet();
scaleSet.playTogether(
ObjectAnimator.ofFloat(view, "scaleX", 0.5f),
ObjectAnimator.ofFloat(view, "scaleY", 0.5f));
mainSet.playSequentially(
ObjectAnimator.ofFloat(view, "alpha", 0.5f),
scaleSet);
mainSet.start();
mainSet.end();
This causes the mainSet to call end() on all its children. But since AnimatorSet.end() is broken the scaleSet does not set ending values. I attempted to extend AnimatorSet class and fix this but soon found out it is marked final.
In my app I mostly use animations but have some few cases where animations are not needed. Does anyone have an idea how to achieve the proper behaviour?
You can do that on all child animations with:
for (Animator animation : mainSet.getChildAnimations())
{
animation.start();
animation.end();
}
I know this is an old question but a recursive approach can solve this:
void endAnimationsRecursively(final Animator mainAnimator){
if (mainAnimator instanceof AnimatorSet) {
for (final Animator animator : ((AnimatorSet)
mainAnimator).getChildAnimations()) {
endAnimationsRecursively(animator);
}
mainAnimator.end();
mainAnimator.cancel();
}
}
I am trying to set blink animation on two words so that they blink one after the other, but what ever I do only 2nd word is displayed, can any one provide me method for doing the same, I am working with API level 10 so, cannot use "Animatorset".
AnimationSet set = new AnimationSet( true );
Animation blink = new AlphaAnimation(1, 0 );
blink.setDuration(duration);
blink.setFillAfter(true);
set.addAnimation( blink );
txtvw.setText("FIRST");
txtvw.setVisibility(View.VISIBLE);
txtvw.setAnimation(blink);
AnimationSet set2 = new AnimationSet( true );
Animation blink2 = new AlphaAnimation(1, 0 );
blink2.setDuration(duration);
blink2.setFillAfter(true);
set2.addAnimation( blink );
txtvw.setText("SECOND");
txtvw.setVisibility(View.VISIBLE);
txtvw.setAnimation(blink2);
if your code is like this, your text "first" gets replaced by text "Second" immediately. And the animation is shown. This animation gives an illusion that only second is blinking. Your text first is being set for microseconds but it immediately gets replaced by second.
If you want to show both the texts, you may need to use Thread
Using two animation sets for the same animations (that is, "blinking animation") is an overkill. You may just repeat your animation 2 times. Use setRepeatCount(int) in conjunction with setRepeatMode(int) to achieve this.
If you insist on using the code you have provided in your post, you will need to specify animation offset. Animation offset indicates "how much time should animation wait before start". For example, if you have Animation a and b, and want b happen after a, you might use the code:
b.setStartOffset(a.getDuration());
Then b animation will happen just after a has finished.
