recyclerview AnimationDrawable 无法停止

发现一个问题，AnimationDrawable 配合recyclerview 使用时，在界面全部刷新的时候，调用stop方法，并不会使动画停止。但是手动调用 stop 方法，则可以进行停止，不知道是什么原因。

先附上最后的解决方案，就是在bind 数据的时候，将之前的AnimationDrawable置空，然后重新设置动画。

代码如下

 AnimationDrawable ad = (AnimationDrawable) ivVoice.getBackground();
            if (voiceClass.isPlayAudio()) {
                if (!ad.isRunning()) {
                    ad.start();
                }
            } else {
                if (ad.isRunning()) {
                    ad.stop();
                    ad.selectDrawable(0);
                }
                ivVoice.setBackground(null);
                ivVoice.setBackgroundResource( R.drawable.r_chat_voice_play);
            }

这两句是我额外加上的。

   ivVoice.setBackground(null);
                ivVoice.setBackgroundResource( R.drawable.r_chat_voice_play);

我在fragement里面如此触发单条刷新 是可以停止的。

 mVoiceAdapter.notifyItemChanged(index,VoiceAdapter.FLAG_UPDATE_PROGRESS);

@Override
        public void onBindViewHolder(@NonNull VoiceVH holder, int position, @NonNull List<Object> payloads) {
            if(payloads==null||payloads.size()==0)
                onBindViewHolder(holder,position);
            else
            {
                String flag=payloads.get(0).toString();
                switch (flag)
                {
                    case VoiceAdapter.FLAG_UPDATE_PROGRESS:
                        holder.updateVoiceStatus();
                        break;
                }
            }
        }

  public void updateVoiceStatus( ){
            //显示播放 的动画
            AnimationDrawable ad = (AnimationDrawable) ivVoice.getBackground();


            if (mVoiceClass.isPlayAudio()) {
                if (!ad.isRunning()) {
                    ad.start();
                }
            } else {
                if (ad.isRunning()) {
                    ad.stop();
                    ad.selectDrawable(0);

                }

感觉是跟viewholder复用有关但是，我重写onViewRecycled 还是无法停止。实在是找不出原因了。复用的ad.hashcode 也是相同的，但是调用的位置不同，stop()方法就是停止不了动画。。。。。

  @Override
        public void onViewRecycled(VoiceVH holder) {
            super.onViewRecycled(holder);
         //   holder.StopVoice();
         holder.updateVoiceStatus(false);
        }

完整的代码（加载30项，然后播放前几项和最后几项（前几项和后几项是不在一页的），然后刷新，发现屏幕外的帧动画并未停止）
