如何在ExpandableView中識別「onClick視圖」並獲取「groupId」

Question

從下面的代碼（在ExpandableView Adapter中）我點擊圖像（iv）後如何獲得組ID。 如果用戶點擊組列表，我想像往常一樣點擊它，但是如果用戶點擊組列表中的圖像，我想調用其他一些操作，並且需要SampleGroup的id。

public View getGroupView(int groupPosition, boolean isExpanded, View converView, ViewGroup parent){ 

    SampleGroup group = (SampleGroup)getGroup(groupPosition); 

    if(convertView == null){ 
      LayoutInflater layoutInflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      convertView = layoutInflater.inflate(R.layout.list_group, null); 
    } 

    ImageView iv = (ImageView)convertView.findViewById(R.id.some_iv): 
    TextView tv = (TextView)convertView.findViewById(R.id.some_tv); 

    iv.setImageDrawable(group.getImage()); 
    iv.setOnClickListener(onClickLintener); 
    tv.setText(group.getText()); 
} 


OnClickListener onClickLintener = new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     //How to get group id here??? 
    } 
}; 

public class SampleGroup{ 
    private int id; 
    private String name; 
    private Drawable image; 

    public SampleGroup(int id, String name, Drawable image){ 
      this.id = id; 
      this.name = name; 
      this.image = image; 
    } 

    public int getId(){ 
      return id; 
    } 

    public void setId(int id){ 
      this.id = id; 
    } 

    public String getName(){ 
      return name; 
    } 

    public void setName(String name){ 
      this.name = name 
    } 

    public Drawable getImage(){ 
      return image; 
    } 

    public void setImage(Drawable image){ 
      this.image = image 
    } 
}

試試這個：

public View getGroupView(int groupPosition, boolean isExpanded, View converView, ViewGroup parent){ 
    ...... 
    ImageView iv = (ImageView)convertView.findViewById(R.id.some_iv); 
    iv.setTag(group.id); 
} 

然後

OnClickListener onClickLintener = new OnClickListener() { 
    @Override 
    public void onClick(View v) { 
     //How to get group id here??? 
     int groupId = (Integer) v.getTag(); 
    } 
};
