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) {
        // ...
    }
}
