如何在Android的listView的每个项目中为图像添加监听器

我遇到此问题。我想创建一个listView来显示所有用户的信息，包括昵称，真实姓名和个人资料图片。现在我想为每个配置文件图像添加监听器，因此用户可以单击每个图像来查看更多信息。我不知道如何添加监听器。这里是代码。请帮助我如何添加侦听器。任何帮助将不胜感激。如何在Android的listView的每个项目中为图像添加监听器

public class SearchActivity extends ListActivity implements LoaderManager.LoaderCallbacks<Cursor>, OnClickListener{ 

    private SimpleCursorAdapter adapter; 
    private ListView listView;

代码，我认为你的问题或非常相似的1 http://stackoverflow.com/questions/16674000/on-a-listview-items-child-click 2. http://stackoverflow.com/questions/3959840/listview-and-propagating-click-events-from-children-views-the-items – Yurets 2015-04-02 02:52:10

感谢您分享链接。但我不知道如何创建新的适配器。 – John 2015-04-02 02:56:29

我想出了一些东西。我可以编辑setViewBinder。下面

adapter.setViewBinder(new SimpleCursorAdapter.ViewBinder() { 

     @Override 
     public boolean setViewValue(View view, Cursor cursor, int columnIndex) { 
      final int id = columnIndex; 
      switch(view.getId()) { 
      // here can add one more line in the main page for each account 
      case R.id.text2: 
       ((TextView)view).setText(String.format("Show user's real name")); 
       return true;  
      case R.id.avatar: 
       byte[] imageByte = cursor.getBlob(columnIndex); 
       ((ImageView)view).setImageBitmap(DbBitmapUtility.getResizedBitmap(DbBitmapUtility.getImage(imageByte),125,125)); 
       ((ImageView)view).setClickable(true); 
       ((ImageView)view).setOnClickListener(new View.OnClickListener() { 
        @Override 
        public void onClick(View v) { 
         Toast.makeText(getBaseContext(),"Go to view more information."+"columnIndex: "+id,Toast.LENGTH_LONG).show(); 
        } 
       }); 
       return true; 
      } 
      return false; 
     } 
    });
