ListView 数据混乱处理
该继承自BaseAdapter的类,以下的重写方法,实现如下。<span style="font-family: Arial, Helvetica, sans-serif;"> //以下是使用数据模型,重新构建视图,在ListView中存在重用View的问题,故而,在滚动刷新一个新view的数据就是根据数据中得数据重新设置即可</span>
<pre name="code" class="java">@Override
    public View getView(int i, View view, ViewGroup viewGroup) {
        ViewHolder viewHolder;

        if(view == null){
            view = View.inflate(context, R.layout.stop_item_activity,null);

            viewHolder = new ViewHolder();
            viewHolder.stopTitle = (TextView) view.findViewById(R.id.stop_title_textview);
            viewHolder.sortTextView = (TextView) view.findViewById(R.id.stop_seq_state_shape);

            viewHolder.liveIconImageView = (ImageView) view.findViewById(R.id.live_icon_imageview);
            viewHolder.stopDetailTextView = (TextView) view.findViewById(R.id.stop_detail_textview);
             view.setTag(viewHolder);

        }else{
            viewHolder = (ViewHolder)view.getTag();
        }

        //begin 实时公交页面渲染
        //
        if(stopList.get(i).getHasBus()){
            viewHolder.sortTextView.setVisibility(View.GONE);
            viewHolder.liveIconImageView.setVisibility(View.VISIBLE);
            viewHolder.stopDetailTextView.setVisibility(View.VISIBLE);
            viewHolder.stopTitle.setTextColor(Color.RED);

        }else{//此分支必须要,重置viewHolder中view中得值
            viewHolder.sortTextView.setVisibility(View.VISIBLE);
            viewHolder.liveIconImageView.setVisibility(View.GONE);
            viewHolder.stopDetailTextView.setVisibility(View.GONE);
            viewHolder.stopTitle.setTextColor(Color.GRAY);

        }

        String tipText = "车辆"+stopList.get(i).getBusselfid()+"于"+stopList.get(i).getActdatetime()+"到达此站";
        viewHolder.stopDetailTextView.setText(tipText);

        //end

        viewHolder.stopTitle.setText(stopList.get(i).getStop_name());
        viewHolder.sortTextView.setText(i+1+ "");

        viewHolder.line_code = stopList.get(i).getLine_code();
        viewHolder.line_seq = stopList.get(i).getStop_seq();

        return view;
    }

    public class ViewHolder{
        public TextView stopTitle;
        public String line_code;
        public String line_seq;
        public TextView sortTextView;//序号,1,2,3
        public boolean hasBus;
        public String busSelfId;
        public String actDatetime;

        public ImageView liveIconImageView;
        public TextView stopDetailTextView;
    }
