GridView OnClick侦听器有时不工作

recycle custom-adapter gridview android

我有一个奇怪的问题。我有一个包含9项(0-8)的gridView(可以多/少)。如下图所示,它显示了我设备屏幕上的前4项。

每当单击一个项目时,都会添加一个绿色的勾号。它几乎每次都能正常工作。但每当我向下滚动并快速单击时,第5个(第4项)项的click侦听器不会立即触发。这可能是一个小问题,但从用户的角度来看,有时可能有点烦人。请告诉我怎样才能做到完美?以下是我的customAdapter的代码:

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

        View rowView = convertView;
        Holder holder = null;

        if (rowView == null) {
            inflater = (LayoutInflater) mContext.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
            rowView = inflater.inflate(R.layout.single_griditem_gitfamount, null);
            holder = new Holder();
            holder.textViewGiftAmount = (TextView) rowView.findViewById(R.id.textViewGridAmount);
            holder.imageViewGiftTick = (ImageView) rowView.findViewById(R.id.imageViewGridTick);
            holder.cardViewGridAmount = (CardView) rowView.findViewById(R.id.cardViewGridAmount);
            rowView.setTag(holder);
        } else {
            rowView = convertView;
            holder = (Holder) rowView.getTag();
        }
        holder.textViewGiftAmount.setText("Item " + position);

            if (position == clickedpos) {
                holder.imageViewGiftTick.setVisibility(View.VISIBLE);
            }
            else{
                holder.imageViewGiftTick.setVisibility(View.GONE);
            }

         //  final Holder h = holder;
           holder.cardViewGridAmount.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                clickedpos = position;
                notifyDataSetChanged();

            }
        });

        return rowView;
    }

如果您正在单击完整项目,则可以选择itemclicklistener

gridview.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> parent, View v, int position, long id) {
            Toast.makeText(MainActivity.this, "" + position, Toast.LENGTH_SHORT).show();
        }
    });
