检测ValueAnimator完成的时间 [英] Detecting when ValueAnimator is done

问题描述

现在，我通过检查进度何时达到100来检测ValueAnimator的结尾.

Right now I am detecting the end of my ValueAnimator by checking when the progress has reached 100...

//Setup the animation
ValueAnimator anim = ValueAnimator.ofInt(progress, seekBar.getMax());

//Set the duration

anim.setDuration(Utility.setAnimationDuration(progress));

anim.addUpdateListener(new AnimatorUpdateListener() 
{

    @Override
    public void onAnimationUpdate(ValueAnimator animation) 
    {
        int animProgress = (Integer) animation.getAnimatedValue();

        if ( animProgress == 100)
        {
            //Done
        }

        else
        {
            seekBar.setProgress(animProgress);
        }
    }
});

这是正确的方法吗?我通读了文档，并在完成时找不到任何类型的侦听器或回调.我尝试使用isRunning()，但效果不佳.

Is this the correct way? I read through the docs and couldn't find any kind listener or callback for when it completes. I tried using isRunning() but it didn't work as well.

推荐答案

您可以执行以下操作:

ValueAnimator anim = ValueAnimator.ofInt(progress, seekBar.getMax());
anim.setDuration(Utility.setAnimationDuration(progress));
anim.addUpdateListener(new AnimatorUpdateListener() 
{
    @Override
    public void onAnimationUpdate(ValueAnimator animation) 
    {
        int animProgress = (Integer) animation.getAnimatedValue();
        seekBar.setProgress(animProgress);
    }
});
anim.addListener(new AnimatorListenerAdapter() 
{
    @Override
    public void onAnimationEnd(Animator animation) 
    {
        // done
    }
});
anim.start();
