Fehler beim Verwenden von LazyAdapter und getAdapter() zum Abrufen des Werts

Question

Ich verwende LazyAdapter zur Anzeige von Listview, und ich möchte den Wert an eine andere Aktivität übergeben, wenn auf das Element geklickt wird. Ich habe jedoch Probleme, den Wert abzurufen. Bitte hilf mir. MainActivity.java

 list=(ListView)findViewById(R.id.list); 
     //transparent so when scrolling listview won't turn black. 
     list.setCacheColorHint(Color.TRANSPARENT); 
     // Getting adapter by passing JSON data ArrayList 
     adapter=new LazyAdapter(ReviewShowActivity.this, reviewlist); 
     list.setAdapter(adapter); 

     list.setOnItemClickListener(new OnItemClickListener() { 

      @SuppressWarnings("unchecked") 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, 
        int position, long id) { 

       //Having Trouble with this line, how to retrieve value??? 
       HashMap<String, String> map2 = (HashMap<String, String>) list.getAdapter().getItem(position); 

       Intent in = new Intent(getApplicationContext(), SingleReviewActivity.class); 
       in.putExtra(TAG_NAME, map2.get(TAG_NAME)); 
       in.putExtra(TAG_USERREVIEW, map2.get(TAG_USERREVIEW)); 
       in.putExtra(TAG_DATE, map2.get(TAG_DATE)); 
       in.putExtra(TAG_THUMBURL, map2.get(TAG_THUMBURL)); 
       startActivity(in); 
      } 
     }); 

LazyAdapter.java

public class LazyAdapter extends BaseAdapter { 
private Activity activity; 
private ArrayList<HashMap<String, String>> data; 
private static LayoutInflater inflater=null; 
public ImageLoader imageLoader; 

public LazyAdapter(Activity a, ArrayList<HashMap<String, String>> d) { 
    activity = a; 
    data=d; 
    inflater = (LayoutInflater)activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    imageLoader=new ImageLoader(activity.getApplicationContext()); 
} 

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

public Object getItem(int position) { 
    return position; 
} 

public long getItemId(int position) { 
    return position; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 
    View vi=convertView; 
    if(convertView==null) 
     vi = inflater.inflate(R.layout.reviewshow, null); 

    TextView username = (TextView)vi.findViewById(R.id.username); // title 
    TextView userreview = (TextView)vi.findViewById(R.id.userreview); // artist name 
    TextView numlikes = (TextView)vi.findViewById(R.id.numlikes); // duration 
    HashMap<String, String> map = new HashMap<String, String>(); 
    map = data.get(position); 

    //Setting all values in listview 
    username.setText(map.get(ReviewShowActivity.TAG_NAME)); 
    userreview.setText(map.get(ReviewShowActivity.TAG_USERREVIEW)); 
    numlikes.setText(map.get(ReviewShowActivity.TAG_NUMLIKES)); 
    return vi; 
}
