如何从ArrayAdapter中解散AlertDialog

Question

我使用ArrayAdapter创建了单选按钮的单选按钮AlertDialog。当选择比率时可以消除该警报对话框？我在ArrayAdapter类holder.name.setOnClickListener中有OnClick监听器，但我不知道如何去做。

AlertDialog代码：

Builder builder = new Builder(serveris, useris, paswordas, BuildBuildingsViewActivity.this, USER_AGENT); 

         ArrayList<AvailableBuildings> availableBuildings = builder.checkForPossibleBuildings(pastatas.getBuildingLink()); 

         ArrayAdapter<AvailableBuildings> adapter = new AvailableBuildingsAdapter(BuildBuildingsViewActivity.this, R.layout.choice_main, availableBuildings, host, curdid, pastatas.getBuildingLink()); 

         new AlertDialog.Builder(BuildBuildingsViewActivity.this) 
         .setSingleChoiceItems(adapter, 0, null) 
         .setPositiveButton("Cancel", new DialogInterface.OnClickListener() { 
          public void onClick(DialogInterface dialog, int whichButton) { 
           dialog.dismiss(); 
          } 
         }) 
         .show(); 

ArrayAdapter代码：

public class AvailableBuildingsAdapter extends ArrayAdapter<AvailableBuildings> { 

    public DBAdapterBuild db_build; 

     public AvailableBuildingsAdapter(Context context, int textViewResourceId,ArrayList<AvailableBuildings> availableBuildings, String host, String curdid, String aiksteles_link) { 
      super(context, textViewResourceId, availableBuildings); 
      this.context = context; 
      this.availableBuildings = new ArrayList<AvailableBuildings>(); 
      this.availableBuildings.addAll(availableBuildings); 
      this.host = host; 
      this.curdid = curdid; 
      this.aiksteles_link = aiksteles_link; 
      db_build = new DBAdapterBuild(context, host); 
     } 

     private String host; 
     private Context context; 
     private String curdid; 
     private String aiksteles_link; 
     private ArrayList<AvailableBuildings> availableBuildings; 

     static class ViewHolder { 
      RadioButton name; 
     } 

     @Override 
     public View getView(int position, View convertView, ViewGroup parent) 
     { 

      ViewHolder holder; 


      if (convertView == null) { 
       LayoutInflater vi = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       convertView = vi.inflate(R.layout.choice_row, null); 

       holder = new ViewHolder(); 
       holder.name = (RadioButton) convertView.findViewById(R.id.building_name); 
       convertView.setTag(holder); 
       holder.name.setOnClickListener(new View.OnClickListener() { 
        public void onClick(View v) { 
         db_build.open(); 
         RadioButton name = (RadioButton) v; 
         AvailableBuildings building = (AvailableBuildings) name.getTag(); 
         Log.e("Available: ", ""+building.getAvailable_title()+building.getAvailable_code()); 
         Log.e("Available: ", ""+db_build.insertTitle(1, building.getAvailable_title(), aiksteles_link, curdid, 0, 1, building.getAvailable_type(), "3", building.getAvailable_code())); 
         db_build.close(); 


        } 
       }); 
      } else { 
       // view already defined, retrieve view holder 
       holder = (ViewHolder) convertView.getTag(); 
      } 

      AvailableBuildings building = availableBuildings.get(position); 

      if (building == null) { 

      } 
      holder.name.setText(building.getAvailable_title()); 
      holder.name.setTag(building); 

      return convertView; 
     } 
    }

我解决这个问题传递给ArrayAdapter的构造对话框对象和明年做这样的：

holder.name.setOnClickListener(new View.OnClickListener() { 
        public void onClick(View v) { 
         db_build.open(); 
         RadioButton name = (RadioButton) v; 
         AvailableBuildings building = (AvailableBuildings) name.getTag(); 
         Log.e("Available: ", ""+building.getAvailable_title()+building.getAvailable_code()); 
         Log.e("Available: ", ""+db_build.insertTitle(1, building.getAvailable_title(), aiksteles_link, curdid, 0, 1, building.getAvailable_type(), "3", building.getAvailable_code())); 
         db_build.close(); 
         dia.dismiss(); 
        } 
       });
