使用當前的代碼，嘗試修改你的陣列有點像這樣：

int[] img = { null, R.drawable.brazil_flag, R.drawable.croatian_flag, 
     R.drawable.mexico_flag, R.drawable.cameroon_flag, null, R.drawable.spain, 
     R.drawable.netherlands_flag, R.drawable.czech_republic_flag, 
     R.drawable.australia, null, ... }; 

String[] name = { "Group A", "BRA", "CRO", "MEX", "CMR", "Group B","ESP", "NED", "CHI", "AUS", ... }; 

然後在getView在適配器方法做到這一點：

@Override 
public View getView(int position, View convertView, ViewGroup parent) { 
    // TODO Auto-generated method stub 
    layoutInflater = (LayoutInflater) context 
      .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
    View row = null; 
    /// inflate a header view here 
    if (itemDetailsarrayList.get(position).getImage()==null) { 
      row = layoutInflater.inflate(R.layout.row_group_header, parent, 
      false); 
      TextView txt = (TextView) row.findViewById(R.id.groupTitle); 
      txt.setText(itemDetailsarrayList.get(position).getName()); 
    /// Inflate your regular item row here. 
    } else { 
      row = layoutInflater.inflate(R.layout.row_list_group, parent, 
      false); 
      TextView txt = (TextView) row.findViewById(R.id.textView1); 
      ImageView imgv = (ImageView) row.findViewById(R.id.imageView1); 
      txt.setText(itemDetailsarrayList.get(position).getName()); 
      imgv.setImageResource(itemDetailsarrayList.get(position).getImage()); 
    } 
    return row; 
}

    android:layout_width="fill_parent"
