推荐答案

我能够通过使最终位置并添加一个onClick监听器的ImageView来获得点击图像的位置。该记录被点击的图像的位置。

I was able to get the position of the clicked image by making the position final and adding an onClick listener to the imageView. This logs the position of the image that was clicked.

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
  ImageView imageView;
  if (convertView == null) {  
    // if it's not recycled, initialize some attributes
    imageView = new ImageView(mContext);
    imageView.setLayoutParams(new GridView.LayoutParams(85, 85));
    imageView.setScaleType(ImageView.ScaleType.CENTER_CROP);
    imageView.setPadding(8, 8, 8, 8);


    imageView.setOnClickListener(new View.OnClickListener() {

      @Override
      public void onClick(View view) {
        Log.d("onClick","position ["+position+"]");
      }

    });

  } 
  else {
    imageView = (ImageView) convertView;
  }

  imageView.setImageResource(mThumbIds[position]);
  return imageView;
}

或使用本：

对于一个GridView可以使用setOnItemClickListener方法有一个OnItemClickListener监听器。该侦听器会给你，你必须签字覆盖方法

or use this :
For a GridView you can use the setOnItemClickListener method to have an OnItemClickListener listener. That listener will give you a method that you must override with the signature

onItemClick(AdapterView<?> parent, View v, int position, long id)

你在哪里得到的项目中单击的网格和认为是网格的单元格内的位置。这就是你需要什么？

where you get the position of the item in the grid that was clicked and the View that is inside the cell of the grid. Is that what you need?
