在Hashmap中为不同的键获取相同的值

Question

我已经实现了hashmap，其中我已经将接收到的json对象分配给某些字符串，如rvalue，price，dsvalue，并将这些字符串作为值传递给KEY_EXTRA，KEY_PLEVEL，KEY_DISTANCE。然后我传递并将此hashmap添加到arraylist .I已为listview的每个项目定义了cutom视图，我想在其中设置这些值，如rating，distance。当我使用这些数据来设置textview的文本时，它只使用KEY_DISTANCE的值作为text的所有其他textview。价值，价格，dsvalue的值是不同的。

初​​始化：

     public static String KEY_REFERENCE = "reference"; // id of the place
     public static String KEY_NAME = "name"; // name of the place
     public static String KEY_VICINITY = "vicinity"; // Place area name
     public static String KEY_EXTRA ;// Place area name
     public static String KEY_PLEVEL ;
     public static String KEY_DISTANCE;

下面是hashmap代码：

          if(status.equals("OK")){
                    // Successfully got places details
                    if (nearPlaces.results != null) {
                        // loop through each place
                        for (Place p : nearPlaces.results) {

                            String rvalue="-NA-";
                            String price="-NA-";


                            HashMap<String, String> map = new HashMap<String, String>();
                            double rate=p.rating;
                             rvalue = String.valueOf(rate);
                            //Log.d("Rating",rvalue );
                            double latitude = p.geometry.location.lat;
                            double longitude = p.geometry.location.lng;
                            Location selected_location=new Location("locationA");
                            selected_location.setLatitude(userlat);
                            selected_location.setLongitude(userlng);
                        Location near_locations=new Location("locationA");
                            near_locations.setLatitude(latitude);
                            near_locations.setLongitude(longitude);

                        double distance=selected_location.distanceTo(near_locations);
                        double dvalue=(Math.round(distance));
                         String dsvalue = String.valueOf(dvalue)
     // Place reference is used to get "place full details"
                            map.put(KEY_REFERENCE, p.reference);

                            // Place name
                            map.put(KEY_NAME, p.name);


                            map.put(KEY_EXTRA,rvalue);
                             price= p.price_level;
                            map.put(KEY_PLEVEL,price);
                            placesListItems.add(map);
                       //    Log.d("price level",price);

                        map.put(KEY_DISTANCE, dsvalue+" M");
                            placesListItems.add(map);



                        }

                        // list adapter
                        ListAdapter adapter = new SimpleAdapter(nearby_mainactivity.this, placesListItems,
                                R.layout.list_item,
                                new String[] { KEY_REFERENCE, KEY_NAME, KEY_EXTRA, KEY_PLEVEL, KEY_DISTANCE}, new int[] {
                                        R.id.reference, R.id.name, R.id.textView3,R.id.textView5 ,R.id.textView7});

                        // Adding data into listview
                        lv.setAdapter(adapter);

以下是每个litview项目的xml布局：
