I put three ObjectAnimator into AnimatorSet ,when I cancel AnimatorSet or AnimatorSet finishes ,i need record the getAnimatedValue . But when I cancel the AnimatorSet, a ObjectAnimator maybe not had runned and i can call isRunning in onAnimationCancel but how do I judge this ObjectAnimator had runned at onAnimationEnd .
animatorSet.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
}
#Override
public void onAnimationEnd(Animator animation) {
mSunMovPos = (float) sunAnimator.getAnimatedValue();
mCurSunSetColor = (int) sunSetAnimator.getAnimatedValue();
//How do judge nightAnimator had runned ?
mCurNightColor = (int) nightAnimator.getAnimatedValue();
}
#Override
public void onAnimationCancel(Animator animation) {
mSunMovPos = (float) sunAnimator.getAnimatedValue();
mCurSunSetColor = (int) sunSetAnimator.getAnimatedValue();
if (nightAnimator.isRunning())
mCurNightColor = (int) nightAnimator.getAnimatedValue();
}
#Override
public void onAnimationRepeat(Animator animation) {
}
});

My code looks like that:
objectAnimator animator = ObjectAnimator.ofFloat(view, "rotation", 0f, (float) truePosition);
animator.setDuration(totalTime);
animator.setInterpolator(new DecelerateInterpolator());
animator.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animator) {
einsatz = 0;
disableChips();
imageRoulette.setEnabled(false);
}
#Override
public void onAnimationEnd(Animator animator) {
imageRoulette.setEnabled(true);
imageRoulette.setImageDrawable(null);
imageRoulette.setBackgroundResource(R.drawable.roulette);
enableChips();
printNumberAfterRotation(randPosition);
myBets.clear();
einsatz = -1;
gesamtEinsatz = 0;
}
#Override
public void onAnimationCancel(Animator animator) { }
#Override
public void onAnimationRepeat(Animator animator) { }
});
animator.start();
By now I always have to tap on the view to rotate my image. Is there a way to restart it after 10 seconds?
Do you have any suggestions how to fix it?
#Override
public void onAnimationEnd(Animator animator) {
animation.setStartDelay(10000); // 10 SEC
animation.start();
}
I have a TextView in my activity, I would like to show the text, then fade out and hide it completely whenever the activity is started.
I have a wired situation, my code sometimes working (the TextView is fade out and gone), but most of times, it is not working (it could not reach the onAnimationEnd function).
Here is my code for it:
protected void onResume() {
fadeOut = new AlphaAnimation( 1.0f , 0.0f ) ;
fadeOut.setDuration(5000);
//fadeOut.setFillBefore(true);
fadeOut.setFillAfter(true);
//fadeOut.setStartOffset(1000);
fadeOut.setAnimationListener(new Animation.AnimationListener() {
#Override
public void onAnimationStart(Animation animation) {
Log.d(TAG, "fade out start");
}
#Override
public void onAnimationEnd(Animation animation) {
Log.d(TAG, "fade out end");
textRotateHint.setVisibility(View.INVISIBLE);
}
#Override
public void onAnimationRepeat(Animation animation) {
Log.d(TAG, "fade out repeat");
}
});
textRotateHint.setVisibility(View.VISIBLE);
textRotateHint.setText(R.string.rotation_hint);
textRotateHint.startAnimation(fadeOut);
super.onResume();
}
You can use a simple value animator.
ValueAnimator valueAnimator = ValueAnimator.ofFloat(1f, 0f);
valueAnimator.setDuration(5000);
valueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
float alpha = (float) animation.getAnimatedValue();
mTextView.setAlpha(alpha);
}
});
valueAnimator.start();
Now I have to create an animation of a spinning fan. When user click POWER ON button, this fan begin to spin, then keep it's spinning speed at some level.When user click POWER OFF button, it slowing down then it stop.
I make some code as follows：
ImageView mFanImageview;
private ValueAnimator mFanValueAnimator;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_centripetal_particle);
ButterKnife.bind(this);
}
private void startFan() {
mFanValueAnimator = new ValueAnimator();
mFanValueAnimator.setDuration(1000);
mFanValueAnimator.setFloatValues(mFanImageview.getRotation(), mFanImageview.getRotation() + 360);
mFanValueAnimator.setInterpolator(new AccelerateInterpolator());
mFanValueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
mFanImageview.setRotation((Float) animation.getAnimatedValue());
}
});
mFanValueAnimator.addListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
mFanValueAnimator = new ValueAnimator();
mFanValueAnimator.setDuration(500);
mFanValueAnimator.setFloatValues(mFanImageview.getRotation(), mFanImageview.getRotation() + 360);
mFanValueAnimator.setRepeatCount(ValueAnimator.INFINITE);
mFanValueAnimator.setRepeatMode(ValueAnimator.RESTART);
mFanValueAnimator.setInterpolator(new LinearInterpolator());
mFanValueAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
mFanImageview.setRotation((Float) animation.getAnimatedValue());
}
});
mFanValueAnimator.addListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationCancel(Animator animation) {
stopFanValueAnimator().start();
}
});
mFanValueAnimator.start();
}
#Override
public void onAnimationCancel(Animator animation) {
stopFanValueAnimator().start();
}
});
mFanValueAnimator.start();
}
private ValueAnimator stopFanValueAnimator() {
ValueAnimator stopAnimator = new ValueAnimator();
stopAnimator.setDuration(1000);
stopAnimator.setFloatValues(mFanImageview.getRotation(), mFanImageview.getRotation() + 360);
stopAnimator.setInterpolator(new DecelerateInterpolator());
stopAnimator.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
#Override
public void onAnimationUpdate(ValueAnimator animation) {
mFanImageview.setRotation((Float) animation.getAnimatedValue());
}
});
return stopAnimator;
}
#OnClick(R.id.stop_button)
public void onStopButtonClicked() {
mFanValueAnimator.cancel();
}
#OnClick(R.id.start_button)
public void onStartButtonClicked() {
startFan();
}
The animation above seems ok, but I found that the fan spinning speed at the end of AccelerateInterpolator animator is hard to match the beginning of LinearInterpolator.I have to adjust duration of LinearInterpolator animator carefully.
How can I get the update rate at the end of AccelerateInterpolator animator then set the right duration of LinearInterpolator animator?
I think the best approach is set accelerate interpolator initially, and on repeat again set LinearInterpolator. Now in case of repeat put a flag for handling switch off. If the switch off demanded then change value of switch Off flag that will apply Decelerate interpolator and make sure that the animation will not run again.
mFanValueAnimator.addListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationRepeat(Animator animation) {
if (switchOff) {
animation.setInterpolator(new DecelerateInterpolator());
} else {
animation.setInterpolator(new LinearInterpolator());
}
}
});
I'm trying a simple example like having a TextView and translate it from 0% to 100% of the screen width
code is :
anim0 = ObjectAnimator.ofFloat(textViewId00, "translationX", -120f, 480f);
where 480f is the width of my screen.
What I want is the next N times ( n=5 for my example ) to add a delay before it starts.
I have tried to add the delay with setStartDelay() method on onAnimationRepeat but there is no effect.
My code is :
textViewId00 = (TextView) findViewById(R.id.textViewId00);
anim0 = ObjectAnimator.ofFloat(textViewId00, "translationX", -120f, 480f);
anim0.setDuration(2000);
anim0.setRepeatCount(5);
anim0.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
Log.i(TAG, "anim0 onAnimationStart ");
textViewId00.setVisibility(View.VISIBLE);
}
#Override
public void onAnimationEnd(Animator animation) {
Log.i(TAG, "anim0 onAnimationEND " );
}
#Override
public void onAnimationCancel(Animator animation) {
}
#Override
public void onAnimationRepeat(Animator animation) {
Log.i(TAG, "anim0 onAnimation REPEAT " );
anim0.setStartDelay(14000);
}
});
anim0.start();
The textView appears to the screen, moves until it disappears and then again from start without any delay.
I have just tried it using this code and it looks like it is doing what you want it to:
public void animateView() {
Display display = getWindowManager().getDefaultDisplay();
Point size = new Point();
display.getSize(size);
final int screenWidth = size.x;
final ObjectAnimator anim0 = ObjectAnimator.ofFloat(textviewId00, "translationX", -120f, screenWidth);
anim0.setDuration(2000);
anim0.addListener(new Animator.AnimatorListener() {
int count;
#Override
public void onAnimationStart(Animator animation) {
textViewId00.setVisibility(View.VISIBLE);
}
#Override
public void onAnimationEnd(Animator animation) {
if (++count < 5) {
anim0.setStartDelay(14000);
anim0.start();
}
}
#Override
public void onAnimationCancel(Animator animation) {}
#Override
public void onAnimationRepeat(Animator animation) {}
});
anim0.start();
}
I'm trying to animate buttons with fade in animation using AnimatorSet
Button fades in > Click button > Remaining buttons fade out
So in order to do this, I want to set the onClickListner after the animation is completed, but that doesn't seem to work. Clicking a button in the middle of the animation triggers the onClick action:
setQuestion = new AnimatorSet();
setQuestion.playSequentially(fadeinAnimationQ,fadeinAnimation1,fadeinAnimation2,fadeinAnimation3,fadeinAnimation4,fadeinAnimation5);
setQuestion.start();
This is the method that checks if the animation has finished.
private void checkAnimation() {
while (true) {
// Check if animation has ended
if (setQuestion.isRunning() == false) {
assignListners();
break;
}
}
}
You can set an AnimatorListener on fadeinAnimation5.
This will give you an onAnimationEnd callback.
fadeinAnimation5.addListener(new AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
// ...
}
#Override
public void onAnimationRepeat(Animator animation) {
// ...
}
#Override
public void onAnimationEnd(Animator animation) {
// ...
}
#Override
public void onAnimationCancel(Animator animation) {
// ...
}
});
Or, as suggested by slott use an AnimatorListenerAdapter
fadeinAnimation5.addListener(new AnimatorListenerAdapter() {
#Override
public void onAnimationEnd(Animator animation) {
// ...
}
}
I was having a similar problem and here is how I solved it:
private void crossFadeAnimation(final View fadeInTarget, final View fadeOutTarget, long duration){
AnimatorSet mAnimationSet = new AnimatorSet();
ObjectAnimator fadeOut = ObjectAnimator.ofFloat(fadeOutTarget, View.ALPHA, 1f, 0f);
fadeOut.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
}
#Override
public void onAnimationEnd(Animator animation) {
fadeOutTarget.setVisibility(View.GONE);
}
#Override
public void onAnimationCancel(Animator animation) {
}
#Override
public void onAnimationRepeat(Animator animation) {
}
});
fadeOut.setInterpolator(new LinearInterpolator());
ObjectAnimator fadeIn = ObjectAnimator.ofFloat(fadeInTarget, View.ALPHA, 0f, 1f);
fadeIn.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animation) {
fadeInTarget.setVisibility(View.VISIBLE);
}
#Override
public void onAnimationEnd(Animator animation) {}
#Override
public void onAnimationCancel(Animator animation) {}
#Override
public void onAnimationRepeat(Animator animation) {}
});
fadeIn.setInterpolator(new LinearInterpolator());
mAnimationSet.setDuration(duration);
mAnimationSet.playTogether(fadeOut, fadeIn);
mAnimationSet.start();
}
You can actually set a listener to the AnimatorSet directly since AnimatorSet inherits from Animator. Here's some code:
import android.animation.Animator;
AnimatorSet setQuestion = new AnimatorSet();
setQuestion.playSequentially(fadeinAnimationQ,fadeinAnimation1,fadeinAnimation2,fadeinAnimation3,fadeinAnimation4,fadeinAnimation5);
setQuestion.addListener(new Animator.AnimatorListener() {
#Override
public void onAnimationStart(Animator animator) {
}
#Override
public void onAnimationEnd(Animator animator) {
// !! turn on your onClickListener here !!
}
#Override
public void onAnimationCancel(Animator animator) {
}
#Override
public void onAnimationRepeat(Animator animator) {
}
});
setQuestion.start();
