android - ListView 不更新行 View

Question

我已经使用 ArrayAdapter 创建了一个自定义 ListView。 ListView 的行有两个 View ，一个是主视图，另一个是隐藏的，当单击主视图上的 TextView 时它会出现。

为了在行上显示数据，我创建了一个对象。我的 ListView 中遇到了一些问题。

1. 这个问题有时会出现。每当我从 ListView 中删除一个项目时，我都可以看到该项目已从我的 ArrayList 中删除，然后我调用 notifyDataSetChanged。问题是 ListView 仍然显示已删除的行，但它不可点击(只有 View 在那里)。只有尚未删除的其他行是可点击的。检查图 1。

1. 我在我的对象中使用了一个标志来隐藏/显示隐藏的 View 。但有时它看起来并不好。检查图像 2

2. 有时在隐藏隐藏 View 后它仍然显示在主视图下方。检查图像 3

请帮我解决这个问题。

Answer 1

这里我将演示一个 View 标记。

        ShippingViewHolder holder;
        if (holder == null)
        {
            holder = new ShippingViewHolder(row);
            row.setTag(holder);
        }
        holder = (ShippingViewHolder) row.getTag();
        ShippingOption shippingOption = getShippingOption(position);
        holder.tvRemove.setTag(shippingOption);
        holder.tvRemove.setOnClickListener(new OnClickListener()
        {
            @Override
            public void onClick(View v)
            {

                ShippingOption shippingOption1 =(ShippingOption) v.getTag();

                int pos = getPosition(shippingOption1); // this is the function that will return you the postion of your object from your passed list of object; write it your self.
                showRemoveDialog(shippingOption1.getProductId(), pos);
            }
        });
