android - intent - Comprobar si AnimatorSet ha terminado la animación?

intent transition animation android

Question

Intento animar botones con fade in animation usando AnimatorSet

Button fades in > Click button > Remaining buttons fade out

Para hacer esto, quiero configurar onClickListner after the animation is completed , pero eso no parece funcionar. Al hacer clic en un botón en el medio de la animación se triggers the onClick action :

setQuestion = new AnimatorSet();
setQuestion.playSequentially(fadeinAnimationQ,fadeinAnimation1,fadeinAnimation2,fadeinAnimation3,fadeinAnimation4,fadeinAnimation5);
setQuestion.start();

Este es el método que verifica if the animation has finished .

private void checkAnimation() {
while (true) {
// Check if animation has ended
if (setQuestion.isRunning() == false) {
assignListners();
break;
}
}
}

Estaba teniendo un problema similar y así es como lo resolví:

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();
}

Puede configurar AnimatorListener en fadeinAnimation5. Esto le dará una devolución de llamada onAnimationEnd.

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) {
// ...
}
});

O, como lo sugiere Slott, use un AnimatorListenerAdapter

fadeinAnimation5.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
// ...
}
}
