在AutoCompleteTextView的CustomAdapter中訪問所選項目的值

Question

我試圖通過從列表形式的服務器獲取國家列表來填充autocompletetextview。 我已經能夠使用customAdapter填充autocompletetextview。

public class Country { 

private Integer id; 
private String name; 
private Integer defaultCurrencyId; 
private String phonePrefix; 
private Integer status; 
private Object deletedAt; 
private String createdAt; 
private String updatedAt; 

... standard getter and setter ... 

} 

我使用name在列表中顯示：不過，我已經很難找到一種方法來訪問對象，如id選定項目的其他價值，並defaultCurrencyId

我的國家目標。我需要獲得name的id。

我的自定義CountryAdapter：

public class CountryAdapter extends ArrayAdapter<Country> { 
    private final String MY_DEBUG_TAG = "CountryAdapter"; 
    private ArrayList<Country> items; 
    private ArrayList<Country> itemsAll; 
    private ArrayList<Country> suggestions; 
    private int viewResourceId; 

    public CountryAdapter(Context context, int viewResourceId, ArrayList<Country> items) { 
     super(context, viewResourceId, items); 
     this.items = items; 
     this.itemsAll = (ArrayList<Country>) items.clone(); 
     this.suggestions = new ArrayList<Country>(); 
     this.viewResourceId = viewResourceId; 
    } 

    public View getView(int position, View convertView, ViewGroup parent) { 
     View v = convertView; 
     if (v == null) { 
      LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      v = vi.inflate(viewResourceId, null); 
     } 
     Country country = items.get(position); 
     if (country != null) { 
      TextView countryNameLabel = (TextView) v.findViewById(R.id.textViewItem); 
      if (countryNameLabel != null) { 
//    Log.i(MY_DEBUG_TAG, "getView Country Name:"+country.getName()); 
       countryNameLabel.setText(country.getName()); 
      } 
     } 
     return v; 
    } 

    @Override 
    public Filter getFilter() { 
     return nameFilter; 
    } 

    Filter nameFilter = new Filter() { 
     @Override 
     public String convertResultToString(Object resultValue) { 
      String str = ((Country)(resultValue)).getName(); 
      return str; 
     } 
     @Override 
     protected FilterResults performFiltering(CharSequence constraint) { 
      if(constraint != null) { 
       suggestions.clear(); 
       for (Country country : itemsAll) { 
        if(country.getName().toLowerCase().startsWith(constraint.toString().toLowerCase())){ 
         suggestions.add(country); 
        } 
       } 
       FilterResults filterResults = new FilterResults(); 
       filterResults.values = suggestions; 
       filterResults.count = suggestions.size(); 
       return filterResults; 
      } else { 
       return new FilterResults(); 
      } 
     } 
     @Override 
     protected void publishResults(CharSequence constraint, FilterResults results) { 
      ArrayList<Country> filteredList = (ArrayList<Country>) results.values; 
      if(results != null && results.count > 0) { 
       clear(); 
       for (Country c : filteredList) { 
        add(c); 
       } 
       notifyDataSetChanged(); 
      } 
     } 
    }; 
} 

在我活動：

public void setCountryAdapter(ArrayList<Country> country){ 

     CountryAdapter countryAdapter = new CountryAdapter(getActivity(), R.layout.list_view_row, country); 
     _actvCountry.setAdapter(countryAdapter); 

} 

我試圖使用OnItemSelectedListener這給選擇項目的位置。但我想知道是否可以訪問Country Object中的其他變量。因爲我爲此調整了CustomAdapter。

請讓我知道，如果你需要更詳細的案件。

謝謝。

使用：setOnItemClickListener in autoCompleteTextView並檢索自定義對象。喜歡：

autoCompleteTextView.setOnItemClickListener(new OnItemClickListener() { 
    public void onItemClick(AdapterView<?> parent, View view, int position, long rowId) { 
     Country country = (Country) parent.getItemAtPosition(position); 
     String id = country.getId(); 
     //other information 
    } 
});
