如何将手风琴应用于Listview项目？

Question

嘿伙计们我使用过Listview我想在用户点击Listview时打开另一个布局，或者你可以说像手风琴风格。

我搜索了这个，但没有准确地知道如何做到这一点？

 public class CustomList extends SimpleAdapter {
        private View.OnClickListener callback;

        private Context mContext;
        public LayoutInflater inflater=null;
        public CustomList(Context context, List<? extends Map<String, ?>> data, int resource, String[] from, int[] to , View.OnClickListener callback) {
            super(context, data, resource, from, to);
            mContext = context;
            this.callback = callback;
            inflater = (LayoutInflater)mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }

        @Override
        public View getView(int position, final View convertView, ViewGroup parent) {
            View vi=convertView;
            if(convertView==null)
                vi = inflater.inflate(R.layout.layout, null);
                vi.setOnClickListener(callback);
                vi.setTag(position);
                TextView lay = (TextView)vi.findViewById(R.id.arrow);
                lay.setOnClickListener(new View.OnClickListener() {
                    @Override
                    public void onClick(View view) {
                        LinearLayout li = (LinearLayout) view.findViewById(R.id.popup);
                        li.setVisibility(View.VISIBLE);
                    }
                });



            HashMap < String, Object > data = (HashMap<String, Object>) getItem(position);
            TextView text = (TextView)vi.findViewById(R.id.carprice);
            String name = (String) data.get(TAG_CITY);
            Log.i("City", name);
            text.setText(name);
           // TextView text1 = (TextView)vi.findViewById(R.id.arrow);
            //String name1 = (String)data.get(TAG_CITY);
            //text1.setText(name1);
            TextView text2 = (TextView)vi.findViewById(R.id.carname);
            String name2 = (String)data.get(TAG_CITY);
            text2.setText(name2);

            ImageView image=(ImageView)vi.findViewById(R.id.carimg);
            String image_url = (String) data.get(TAG_ID);
            Log.i("City", image_url);
            Picasso.with(this.mContext).load(image_url).into(image);
            return vi;

        }
    }
