Android - 獲取動態創建的GridItem的ID

我已經使用自定義的Adapter創建了圖像的GridView。它工作正常，但現在我想要在運行時獲取這些圖像的ID，以便將它們之下的泡泡對齊。我可以得到行ID，但不是圖像的ID。請幫忙。Android - 獲取動態創建的GridItem的ID

public class GridAdapter extends BaseAdapter { 
private Context mContext; 
private GridItem[] items; 

public GridAdapter(Context c) { 
    mContext = c; 
    items = GridItem.values(); 
    //inflater = (LayoutInflater) activity.getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
} 

public int getCount() { 
    return items.length; 
} 

public GridItem getItem(int position) { 
    return items[position]; 
} 

public long getItemId(int position) { 
    return position; 
} 

public static class ViewHolder { 
    public ImageView image; 
} 

public View getView(int position, View convertView, ViewGroup parent) { 
    ImageView imageView; 
    if (convertView == null) { 
     imageView = new ImageView(mContext); 
     imageView.setLayoutParams(new GridView.LayoutParams(GridView.LayoutParams.WRAP_CONTENT, GridView.LayoutParams.WRAP_CONTENT)); 
     //imageView.setPadding(10, 10, 10, 10); 
    } else { 
     imageView = (ImageView) convertView; 
    } 
    imageView.setBackgroundResource(items[position].getResourceId()); 
    if(position == 3) { 
     ImageView helpBubble = new ImageView(mContext); 

    } 
    //imageView.setTag(items[position]); 
    return imageView; 
}

}

UPDATE

它的工作原理！我得到資源ID，但現在我無法在單擊的網格項下添加新視圖。它出現在頂部

    LayoutInflater inflate = (LayoutInflater) mContext 
         .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
       RelativeLayout helpBubble = (RelativeLayout) inflate.inflate(R.layout.bubble, null); 

       TextView helpText = (TextView) helpBubble.findViewById(R.id.bubble_text); 
       helpText 
         .setText("Lorem Epsum Dolor Emit ab asdfj asdflqwe fsadf wqrwqer asdfasdf wfsad asdfasdf rqwerqwrw"); 

       Button moreButton = (Button) helpBubble.findViewById(R.id.bubble_button); 
       moreButton.setText("More Info"); 

       RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(
         RelativeLayout.LayoutParams.WRAP_CONTENT, RelativeLayout.LayoutParams.WRAP_CONTENT); 
       lp.addRule(RelativeLayout.BELOW, item.getResourceId()); 

       gridRL.addView(helpBubble, lp);

你getItemId（INT位置） - 方法返回您傳遞給該方法的值每次。

您應該返回類似items [position] .getResourceId（）
