【问题描述】：

我已经尝试过这个Filter ListView with arrayadapter 和这个Filter List 链接，以实现可过滤的列表，但我不断收到此错误：

进程：br.com.soutsapp.user.souts，PID：315 java.lang.IndexOutOfBoundsException：索引 0 无效，大小为 0 在 java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:255) 在 java.util.ArrayList.get(ArrayList.java:308) 在 br.com.soutsapp.user.souts.userInterface.adapter.EstablishmentAdapter.getView(EstablishmentAdapter.java:54)

这个错误发生在我的getView:

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    br.com.soutsapp.user.souts.userInterface.viewHolder.Establishment viewHolder;
    View rowView = convertView;
    if(convertView == null){
        LayoutInflater layoutInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        rowView = layoutInflater.inflate(R.layout.establishment_row, null, true);

        viewHolder = new br.com.soutsapp.user.souts.userInterface.viewHolder.Establishment();
        viewHolder.ivIcon = (ImageView) rowView.findViewById(R.id.iv_icon);
        viewHolder.tvClosingTime = (TextView) rowView.findViewById(R.id.tv_closing_time);
        viewHolder.tvOpeningTime = (TextView) rowView.findViewById(R.id.tv_opening_time);
        viewHolder.tvDistance = (TextView) rowView.findViewById(R.id.tv_place_distance);
        viewHolder.tvName = (TextView) rowView.findViewById(R.id.tv_name);
        viewHolder.tvWorkingStatus = (TextView) rowView.findViewById(R.id.tv_working_status);
        viewHolder.tvType = (TextView) rowView.findViewById(R.id.tv_type);

        rowView.setTag(viewHolder);
    }
    else {
        viewHolder = (br.com.soutsapp.user.souts.userInterface.viewHolder.Establishment) convertView.getTag();
    }

    Establishment establishment = establishmentList.get(position); //Error here
    viewHolder.ivIcon.setImageDrawable(establishment.getIcon());
    viewHolder.tvClosingTime.setText(establishment.getClosingTime().toString("HH:mm"));
    viewHolder.tvOpeningTime.setText(establishment.getOpeningTime().toString("HH:mm"));
    viewHolder.tvName.setText(establishment.getName());
    viewHolder.tvType.setText(establishment.getType());

    viewHolder.tvWorkingStatus.setText(establishment.getWorkingStatusLabel());
    viewHolder.tvWorkingStatus.setTextColor(getColorWorkingStatusLabel(establishment.isWorkingStatus()));

    viewHolder.tvDistance.setText(formatDistance(establishment.getDistance()));

    rowView.setId((int)establishment.getId());
    return rowView;
}

我不知道如何解决这个问题，你能告诉我方法吗？谢谢！

【问题讨论】：

显示getCount()方法并确保从getCount返回establishmentList.size
请添加establishmentList相关代码！似乎establishmentList 没有按预期启动。
你的 getCount() 返回什么？？
建立列表列表大小为零，您可以尝试从零索引获取数据，因此只需检查您的列表大小

【解决方案1】：

覆盖 getCount 方法并返回您的列表大小。在您的适配器类中。

解决问题！

【解决方案2】：

您在哪里填充数据？我的意思是你在哪里设置了for循环来添加数据？
