カスタムリストビューアアダプタからフラグメントクラス内でonItemClickを呼び出す

Question

私はカスタムリストビューを持っています。それは私の断片の中にあります。私はLazyListviewアダプタを使ってこのリストビューをカスタマイズしていますが、今はjsonを使ってデータベースmysqlからバインドされたlist-viewの選択項目のIDを取得したいと思います。だから、私はLazyListviewアダプターに実装しているOnClickListenerはうまく動作しますが、フラグメント内のメソッドを呼び出そうとすると、フラグメント内に選択されたIDを取得できません。 助けてください。

public class LazyImageLoadAdapter extends BaseAdapter implements OnClickListener{ 

    private Activity activity; 
    private String[] data; 
    private String[] data1; 
    private String[] data2; 
    private String[] data3; 
    private static LayoutInflater inflater=null; 
    public ImageLoader imageLoader; 
    Typeface tf; 
    Typeface tf1; 
    ArrayList<Country> countrylist; 
    ArrayList<Country> mStringFilterList; 

    ValueFilter valueFilter; 
    ArrayList<Country> filterList; 
    public LazyImageLoadAdapter(Activity a, ArrayList<Country> countrylist) { 


     activity = a; 

     this.countrylist = countrylist; 
     mStringFilterList = countrylist; 

     inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 

     // Create ImageLoader object to download and show image in list 
     // Call ImageLoader constructor to initialize FileCache 
     imageLoader = new ImageLoader(activity.getApplicationContext()); 
     //tf = Typeface.createFromAsset(a.getAssets(), "fonts/LobsterTwo-BoldItalic.ttf"); 
     // tf1 = Typeface.createFromAsset(a.getAssets(), "fonts/LobsterTwo-Italic.ttf"); 


    } 

    public int getCount() { 
     return countrylist.size(); 
    } 

    public Object getItem(int position) { 
     return countrylist.get(position); 
    } 

    public long getItemId(int position) { 
     return countrylist.indexOf(getItem(position)); 
    } 

    /********* Create a holder Class to contain inflated xml file elements *********/ 
    public static class ViewHolder{ 

     public TextView text; 
     public TextView text1; 
     public TextView textWide; 
     public ImageView image2; 
     public RatingBar pop_ratingbar; 

    } 

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

     View vi=convertView; 
     ViewHolder holder; 

     if(convertView==null){ 

      /****** Inflate tabitem.xml file for each row (Defined below) *******/ 
      vi = inflater.inflate(R.layout.list_gym, null); 

      /****** View Holder Object to contain tabitem.xml file elements ******/ 

      holder = new ViewHolder(); 
      holder.text = (TextView) vi.findViewById(R.id.title); 
      holder.text1=(TextView)vi.findViewById(R.id.txt_exp); 
      // holder.text1.setBackgroundResource(R.drawable.rating_background); 
      holder.image2=(ImageView)vi.findViewById(R.id.imageview_gym); 
      holder.pop_ratingbar=(RatingBar)vi.findViewById(R.id.ratingBar); 

      /************ Set holder with LayoutInflater ************/ 

      vi.setTag(holder); 


     } 

     else 

     holder=(ViewHolder)vi.getTag();   
     Country country = countrylist.get(position); 
     holder.text.setText(country.getName()); 
     //holder.text.setText(country.getIso_code().toString()); 
     holder.text1.setText(" Total experience: "+country.getRatingC()+" years"); 
     String s1 = country.getFlag(); 
     Float f1= Float.parseFloat(s1); 
     holder.pop_ratingbar.setRating(f1); 
     //holder.text.setText(country.getName()); 
     //holder.text.setTypeface(tf); 
     //holder.text1.setText(" Based On("+country.getRatingC()+") Rating"); 
     //holder.text1.setTypeface(tf); 
     ImageView image1 = holder.image2; 



     //DisplayImage function from ImageLoader Class 
     imageLoader.DisplayImage(country.getIso_code().toString(), image1); 

     /******** Set Item Click Listner for LayoutInflater for each row ***********/ 
     vi.setOnClickListener(new OnItemClickListener(Integer.parseInt(country.getRid().toString()))); 



     return vi;  

    } 





    } 

    @Override 
    public void onClick(View arg0) { 
     // TODO Auto-generated method stub 

    } 


    /********* Called when Item click in ListView ************/ 
    private class OnItemClickListener implements OnClickListener{ 
     private int mPosition; 

     OnItemClickListener(int position){ 

      mPosition = position;

      act.onItemClick();

問題は構文です。このラインで

GymFragment act = GymFragment(activity); 

： あなたはこの行を置き換える必要があり

GymFragment act = new GymFragment(activity);
