Question

我已经使用自定义适配器实现了gridview，并且适配器使布局膨胀并在gridview的每个元素中显示两个项目。一个是imageview，另一个是关闭按钮，它位于图像的右上方。我的问题是当我点击十字按钮时从网格中删除元素。我要为两张图片触发事件。所以我计划在适配器内给出关闭按钮事件。最后它可以工作，但我无法删除点击的位置。每当我点击关闭按钮图像时，它将从我的arraylist中删除最后一个元素。请帮助我。

我的代码在下面：

@Override
public View getView( int position, View convertView, ViewGroup parent)
{

    View MyView = convertView;



    pos=position;
    positionForCheck =(Object) pos;
    if (convertView == null)
    {           

        LayoutInflater li = (LayoutInflater) MyContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        MyView = li.inflate(R.layout.grid_item_for_bag, null);


        // Add The Image!!!
        ImageView imageSrc = (ImageView) MyView.findViewById(R.id.grid_item_bag_image);

        ImageView imageClose = (ImageView) MyView.findViewById(R.id.grid_item_bag_close);


    }   

    imageSrc.setImageResource(MyList.get(position));


    imageClose.setImageResource(R.drawable.closeicon_31x31);
    imageClose.setOnClickListener(new OnClickListener()
        {
            @Override
            public void onClick(View v)
            {   

                                    MyList.remove(position)
                notifyDataSetChanged();
            }
        });


    return MyView;
}

我得到了输出。代码如下所示

 @Override
public View getView( int position, View convertView, ViewGroup parent)
{

View MyView = convertView;
ViewHolder holder;


pos=position;
positionForCheck =(Object) pos;
if (convertView == null)
{           

    LayoutInflater li = (LayoutInflater) MyContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    MyView = li.inflate(R.layout.grid_item_for_bag, null);
    holder = new ViewHolder();

    // Add The Image!!!
    holder.imageSrc = (ImageView) MyView.findViewById(R.id.grid_item_bag_image);

    holder.imageClose = (ImageView) MyView.findViewById(R.id.grid_item_bag_close);
    MyView.setTag(holder);

}   
 else
 {
 holder =(ViewHolder) MyView.getTag();
 }

holder.imageSrc.setImageResource(MyList.get(position));

holder.imageClose.setTag(position)
holder.imageClose.setImageResource(R.drawable.closeicon_31x31);
holder.imageClose.setOnClickListener(new OnClickListener()
    {
        @Override
        public void onClick(View v)
        {   
            int posi = Integer.parseInt(v.getTag().toString());
            MyList.remove(posi)
            notifyDataSetChanged();
        }
    });


return MyView;
 }
