我使用了两种不同颜色的自定义行。但是它返回的是黑色的同一行。我也有黄色的行,但它只返回黑色的行。我无法理解它,因此在下面共享了我的源代码。请帮我

json_orders = json.getJSONArray("orders");
                for(int i = 0; i < json_orders.length(); i++){
                JSONObject c = json_orders.getJSONObject(i);

                // Storing  JSON item in a Variable
                String orderDate = c.getString("orderDate");
                String orderTime = c.getString("orderTime");
                String orderId = c.getString("orderId");
                String driverStatusId = c.getString("driverStatusId");

                // Adding value HashMap key => value


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

                map.put("orderDate", orderDate);
                map.put("orderTime", orderTime);
                map.put("orderId", orderId);

                oslist.add(map);
                list=(ListView)view.findViewById(R.id.list);

                ListAdapter  adapter = new SimpleAdapter(getActivity(), oslist, i, null, null);

                if (!driverStatusId.equals("4"))
                {
                    adapter = new SimpleAdapter(getActivity(), oslist,
                            R.layout.list_row_new,
                            new String[] { "orderDate", "orderTime"}, new int[] {
                            R.id.orderDate, R.id.orderTime});
                }
                else {
                    adapter = new SimpleAdapter(getActivity(), oslist,
                            R.layout.list_row,
                            new String[] { "orderDate", "orderTime"}, new int[] {
                            R.id.orderDate, R.id.orderTime});
                }

                list.setAdapter(adapter);

                list.setOnItemClickListener(new AdapterView.OnItemClickListener() {

                    @Override
                    public void onItemClick(AdapterView<?> parent, View view,
                                            int position, long id) {
                        //Toast.makeText(getActivity(), "You Clicked at "+oslist.get(+position).get("orderId"), Toast.LENGTH_SHORT).show();

                        Fragment fragment = null;
                        fragment = new OrderDetailsFragment();

                        final Bundle bundle = new Bundle();
                         bundle.putString("orderId", oslist.get(+position).get("orderId"));
                         Log.i("BUNDLE", bundle.toString());
                         fragment.setArguments(bundle);

                        FragmentManager fragmentManager = getFragmentManager();
                        fragmentManager.beginTransaction()
                                .replace(R.id.frame_container, fragment, "OrderDetailsFragment").commit();

                        //new UpdateDestinationInfo().execute(String.valueOf(db.getUserDetails().get("currentorderid")), oslist.get(+position).get("longlat"));
                       // Toast.makeText(getActivity(), "You Clicked at "+String.valueOf(db.getUserDetails().get("id")), Toast.LENGTH_SHORT).show();

                    }

最佳答案

如果在ListView中有多个视图,则将需要除SimpleAdapter以外的其他内容,因为您需要覆盖一些方法。您将最终需要扩展BaseAdapter来创建自定义适配器。制作自己的适配器时需要的第一种方法是getViewTypeCount()。这告诉适配器存在一定数量的视图类型,并且应该考虑这一点。您需要覆盖的第二种方法是getItemViewType(),以便ListView知道哪些视图具有哪种类型,以便可以相应地处理视图回收。然后,在getView()方法中,根据位置,根据视图类型返回不同的视图类型。
