如何設置OnClickLitsener到按鈕與覆蓋SimpleCursorAdapter的ListView

Question

我現在用simplecursoradapter來從數據庫中獲取數據有一個ListView和我查詢從數據庫的鏈接，並將其列表中的每一行分配給一個按鈕和我重寫simplecursoradapter類來設置按鈕的onclicklistener，但我的代碼不工作，有誰告訴我有什麼問題？

這是我的適配器：

public class ChannelAdapter extends SimpleCursorAdapter{ 

    private LayoutInflater mInflater; 
    private List<ChannelPoster> items; 
    private Context mContext; 
    private String dblink; 

    public ChannelAdapter(Context context, int layout, Cursor c, String[] from, 
      int[] to) { 
     super(context, layout, c, from, to); 
     // TODO Auto-generated constructor stub 
    } 

    @Override 
    public View getView(int position,View convertView,ViewGroup par) 
    { 
     ViewHolder holder; 

     if(convertView == null) 
     { 

     convertView = mInflater.inflate(R.layout.channelview, null); 

     holder = new ViewHolder(); 
     holder.image = (ImageView) convertView.findViewById(R.id.poster); 
     holder.text = (TextView) convertView.findViewById(R.id.channel); 
     holder.button = (ImageButton) convertView.findViewById(R.id.douban); 
     convertView.setTag(holder); 

     } 
     else 
     { 
     holder = (ViewHolder) convertView.getTag(); 
     } 

     ChannelPoster tmpN=(ChannelPoster)items.get(position); 

     holder.text.setText(tmpN.getChannel()); 
     holder.image.setImageResource(tmpN.getPoster()); 
     holder.button.setOnClickListener(new ImageButton.OnClickListener() 
     { 
     public void onClick(View v) 
     { 
     // TODO Auto-generated method stub 

      Intent intent = new Intent(); 
      intent.setClass(mContext, Doubanframe.class); 
      Bundle bunde = new Bundle(); 
      bunde.putString("dblink",dblink); 
      intent.putExtras(bunde); 
      mContext.startActivity(intent); 

      } 

     }); 
     return convertView; 
    } 


    private class ViewHolder 
    { 
    ImageView image; 
    TextView text; 
    ImageButton button; 
    } 
    } 

，這是我如何填充ListView：

mDB = new ChannelDB(this); 

     String[] columns = {mDB.KEY_ID, mDB.KEY_POSTER, mDB.KEY_CHANNEL, mDB.KEY_PATH, mDB.KEY_DBLINK}; 
     String table = mDB.channelS_TABLE; 

     c = mDB.getHandle().query(table, columns, null, null, null, null, null); 

     startManagingCursor(c); 

     SimpleCursorAdapter adapter = new SimpleCursorAdapter(this, 
       R.layout.channelview, 
       c, 
       new String[] {mDB.KEY_POSTER, mDB.KEY_CHANNEL, mDB.KEY_DBLINK}, 
       new int[] { R.id.poster, R.id.channel, R.id.douban}); 

     channellist.setAdapter(adapter); 

logcat的

@Override 
    public View getView(int position, View convertView, ViewGroup parent) { 
     View view = convertView; 
     if (view == null) 
      view = LayoutInflater.from(DummyListViewProjectActivity.this).inflate(R.layout.list_item, parent, false); 
     TextView tv = (TextView) view.findViewById(R.id.text); 
     tv.setText(adapterItems.get(position)); 
     Button bt = (Button) view.findViewById(R.id.button); 
     bt.setText(adapterItems.get(position)); 
     bt.setTag(adapterItems.get(position)); 
     bt.setOnClickListener(new OnClickListener() { 

      @Override 
      public void onClick(View v) { 
       Toast.makeText(DummyListViewProjectActivity.this, v.getTag().toString(), Toast.LENGTH_SHORT).show(); 
      } 
     }); 
     return view; 
    }
