android spinner set tag

Question

我正在開發應用程序。在這我從數據庫中填充微調。我得到了由描述和代碼組成的arrayList。我需要將代碼設置爲每個描述的標記。是否有可能爲微調器中的單個項目添加標籤。

嘗試簡單的自定義適配器：

public class MySpinnerAdapter extends BaseAdapter { 

     private Activity context; 

     public CitiesSpinnerAdapter(Activity context){ 
      this.context=context; 
     } 

     @Override 
     public int getCount() { 
      return 0; 
     } 

     @Override 
     public Object getItem(int position) { 
      return null; 
     } 

     @Override 
     public long getItemId(int position) { 
      return 0; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) { 
      RelativeLayout item= (RelativeLayout)context.getLayoutInflater().inflate(R.layout.<your spinner item layout name>, null); 
//set your data to layout components 
      item.setTag(<your tag object>); 

      return item; 
     }
