Android 用于在ListView中打开或关闭视图的动画，只有一个动画工作

我有一个列表视图，表示一周中的7天。每行都有一个标题和内容

我已经设置了单击行标题的动画。单击时，该行的内容将向上/向下滑动

目前只有用于向下滑动打开内容的动画工作，无法理解为什么向上滑动动画不工作？！&^@

ListView适配器的getView

向下滑动动画

向上滑动动画

是否在调用动画后直接将view设置为view.GONE？看起来你的动画没有任何设定的时间，所以我想它会很快进入下一行代码。@RedRumming不幸的是，这并没有修复它。谢谢你的意见！

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    final ViewHolder holder;

    if (convertView == null) {

        holder.header = (LinearLayout) convertView.findViewById(R.id.header);
        holder.day = (CustomFontBoldTextView) convertView.findViewById(R.id.day);
        holder.isActive = (CustomFontBoldTextView) convertView.findViewById(R.id.is_active);
        holder.container = (LinearLayout) convertView.findViewById(R.id.container);
        holder.rangeBar = (RangeBar) convertView.findViewById(R.id.rangebar);
        holder.tvStartTime = (CustomFontBoldTextView) convertView.findViewById(R.id.start_time);
        holder.tvEndTime = (CustomFontBoldTextView) convertView.findViewById(R.id.end_time);
        convertView.setTag(holder);
    }
    else {
        holder = (ViewHolder) convertView.getTag();
    }
