如何在没有初始动画的情况下更新ListView中的SpeedView？

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    // 获取SpeedView实例
    SpeedView speedView;
    if (convertView == null) {
        // 初始化convertView
        convertView = LayoutInflater.from(context).inflate(R.layout.list_item, parent, false);
        speedView = convertView.findViewById(R.id.speed_view);
        convertView.setTag(speedView);
    } else {
        speedView = (SpeedView) convertView.getTag();
    }

    // 更新SpeedView的数值
    float newSpeed = getNewSpeed(position); // 根据位置获取新的数值
    speedView.setSpeed(newSpeed);

    // 触发重绘
    speedView.invalidate();

    return convertView;
}
