如何在列表視圖中設置OnClickLitsener爲按鈕

Question

我現在有一個使用simplecursoradapter從數據庫獲取數據的列表視圖，並且查詢數據庫中的鏈接並將其分配給列表中每一行的按鈕，並且我正在重寫simplecursoradapter類爲按鈕設置onclicklistener，但我的代碼不工作，有誰告訴我有什麼問題？ THX

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);

嘗試android.view.View.OnClickListener代替

@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); 
    holder.button.setOnClickListener(new android.view.View.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); 

     } 

    });   

    convertView.setTag(holder); 

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

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

    holder.text.setText(tmpN.getChannel()); 
    holder.image.setImageResource(tmpN.getPoster()); 
    return convertView; 
} 

Answer 2

public class ChannelAdapter extends SimpleCursorAdapter implements OnClickListener { 

@Override 
       public void onClick(View view) { 
         public void onClick(View view) { 

       int view_id = view.getId(); 
       Log.d(THIS_FILE, "Im clicked...."); 



       switch (view_id) { 

       case R.id.douban: { 
         dialFeedback.giveFeedback(ToneGenerator.TONE_DTMF_0); 
         keyPressed(KeyEvent.KEYCODE_0); 
         break; 
       } 
       } 
} 





}
