设置图像的名称为ImageButton标签。然后您可以在onClick()中检索它。使用setTag()和getTag()这个：

String imageName = "_" + list.get(i).toString(); 
    int resourceId = res.getIdentifier(imageName, "drawable", getPackageName()); 
    b.setTag(imageName); 
    b.setImageResource(resourceId); 
    b.setOnClickListener(new View.OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      //at here i want to get the selected image name 
      String clickedImageName = (String)v.getTag(); 

     } 
    });
