gridview中的按钮操作

Question

我有一个gridview，每个网格项中都有一个删除按钮。我的代码如下：

MainActivity

... public ActionResult Index() { IEnumerable<CATEGORIES> categories = _categoriesService.GetCategories(); return View(categories); } ...

generate_photos()

适配器

gd_view.setAdapter(new SampleGridViewAdapter(Photos.this));
                gd_view.setOnScrollListener(new SampleScrollListener(Photos.this));
                gd_view.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                    @Override
                    public void onItemClick(AdapterView<?> parent, View v, int position, long id)
                    {
                        Utilities.custom_toast(Photos.this, "View big", ""+position, "short");
                    }
                });
                gd_view.setOnItemLongClickListener(new AdapterView.OnItemLongClickListener()
                {
                    public boolean onItemLongClick(AdapterView<?> arg0, View arg1, int position, long arg3)
                    {
                        //Utilities.custom_toast(Photos.this, "LONG Press", ""+position, "short");
                        return true;
                    }
                });

问题：

按下删除按钮后，我想刷新gridview，使图片删除从gridview中消失。我试图调用@Override public View getView(int position, View convertView, ViewGroup parent) { LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); View gridView; gridView =new View(context); gridView = inflater.inflate(R.layout.inflated_gridview, null); ImageView btn_delete = (ImageView) gridView.findViewById(R.id.btn_delete); ImageView img_grid = (ImageView) gridView.findViewById(R.id.img_grid); final TextView tv_ref = (TextView) gridView.findViewById(R.id.tv_ref); final String url = getItem(position); Picasso.with(context).load(url).fit().centerCrop().into(img_grid); tv_ref.setText(""+id.get(position)); btn_delete.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { int id = Integer.parseInt(tv_ref.getText().toString()); Records_Photo n = Select.from(Records_Photo.class).where(Condition.prop("photo_Id").eq(id)).first(); n.delete(); } }); return gridView; 无法从静态上下文中引用非静态方法

那么在按下删除按钮后如何刷新gridview？现在看来这是一个循环。

谢谢。

删除图像后，您是否使用adapter.notifyDataSetChanged（）方法进行了检查？
