Question

Lazyadapter for listview（垂直）里面，我做了什么，在水平listview＆amp;上设置lazyadapter HLV在此lazyadapter的自定义布局中声明。

class lazyadapter extends BaseAdapter {
    Context context;

    LayoutInflater inflater;
    ArrayList<HashMap<String, String>> data;

    public lazyadapter(Context context,
            ArrayList<HashMap<String, String>> arraylist) {
        this.context = context;
        data = arraylist;
    }

    @Override
    public int getCount() {
        return data.size();
    }

    @Override
    public Object getItem(int position) {
        return position;
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(final int position, View convertView,
            ViewGroup parent) {
        LayoutInflater inflater = (LayoutInflater) context
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View itemView = inflater
                .inflate(R.layout.horizontal, parent, false);

        HashMap<String, String> mapss;

        mapss = new HashMap<String, String>();

        String dataq = data.get(position).get("subcatname");
        String catname = data.get(position).get("catname");
        String image = data.get(position).get("image");
        String id = data.get(position).get("id");
        mapss.put("dataq", dataq);
        mapss.put("image", image);
        mapss.put("catname", catname);
        mapss.put("id", id);
        TextView uu = (TextView) itemView.findViewById(R.id.textView1);
        hlvSimpleList1 = (HorizontalListView) itemView
                .findViewById(R.id.hlvSimpleList1);

        uu.setText(data.get(position).get("catname"));
        String tttt = data.get(position).get("cc");

        if (tttt.equals("1")) {
            uu.setVisibility(0);
            ap = new ArrayList<HashMap<String, String>>();

        } else {
            uu.setVisibility(8);

            hlvSimpleList1.setVisibility(8);

        }
        ap.add(mapss);
        lazyadapter4 adpp = new lazyadapter4(getApplicationContext(), ap);
        adpp.notifyDataSetChanged();
        hlvSimpleList1.setAdapter(adpp);

        return itemView;

    }
}

在Advance中感谢..请帮助我摆脱这个..

在listview的Row.xml中（你将在适配器的getView（..）函数中膨胀）使用HorizontalScrollView作为Parent元素。

android中垂直列表视图内的水平列表视图
