android - Fancycoverflow 布局无法正常工作

Question

我在我的应用程序中添加了花哨的封面流，它工作正常但问题是，花哨的封面流的 View 显示得很奇怪..

我按照这个例子https://github.com/davidschreiber/FancyCoverFlow

我想要这样的东西

但是我得到的输出是这样的

我的意思是一次只有一张图片显示在屏幕上，在任何一侧我都看不到下一张图片

我的适配器

class CoverAdapter extends FancyCoverFlowAdapter {
        private LayoutInflater inflater;
        public Activity a;
        View vi;
        public ArrayList<HashMap<String, String>> arr;
        public ArrayList<HashMap<String, String>> data;

        public CoverAdapter(Activity homeActivity, ArrayList<HashMap<String, String>> myList) {

            arr = myList;
            a = homeActivity;
            inflater = (LayoutInflater) a.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        }

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

        @Override
        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return position;
        }

        @Override
        public long getItemId(int position) {
            // TODO Auto-generated method stub
            System.out.println("position=" + position);
            return position;
        }

        @Override
        public View getCoverFlowItem(int position, View convertView, ViewGroup parent) {
            Log.d("aaa", position + "");
            View vi = convertView;
            if (vi == null)
                vi = inflater.inflate(R.layout.create_club_inflate, null);

            TextView date1 = (TextView) vi.findViewById(R.id.txtDate1);
            TextView date = (TextView) vi.findViewById(R.id.txtDate);
            TextView team1_name = (TextView) vi.findViewById(R.id.txtTeamName);
            TextView team2_name = (TextView) vi.findViewById(R.id.txtVanue);
            TextView ground = (TextView) vi.findViewById(R.id.txt_time);

            HashMap<String, String> product = new HashMap<String, String>();
            product = arr.get(position);

            System.out.println("name 1= " + product.get("str_team1_name") + " team 2="
                    + product.get("str_team2_obj_name"));
            date1.setText(product.get("str_srs"));
            date.setText(product.get("str_startdt"));
            team1_name.setText(product.get("str_team1_name"));
            team1_name.setAlpha(5000);
            team2_name.setText(product.get("str_team2_obj_name"));
            team2_name.setAlpha(5000);
            Typeface font = Typeface.createFromAsset(getAssets(), "TitilliumText22L006.otf");

            int[] color = { Color.rgb(100, 100, 100), Color.rgb(255, 255, 255) };
            float[] color_position = { 0, 1 };
            TileMode tile_mode = TileMode.MIRROR; // or TileMode.REPEAT;
            LinearGradient lin_grad = new LinearGradient(0, 0, 0, 50, color, color_position, tile_mode);
            Shader shader_gradient = lin_grad;
            team1_name.getPaint().setShader(shader_gradient);
            team2_name.getPaint().setShader(shader_gradient);
            team1_name.setTypeface(font);
            team2_name.setTypeface(font);
            ground.setText(product.get("str_grnd"));

            product.get("str_sName");
            product.get("str_team2_obj_sName");


            String first_team_id = product.get("str__team1_id");
            String second_team_id = product.get("str_team2_obj_id");


            return vi;
        }
