Question

在我的应用程序中，每当我触摸列表视图项目布局时，我想删除自定义列表项中的行。我尝试在位置的帮助下删除。但它已经停止了。

代码：

  @Override


  public View getView(final int position, View convertView, ViewGroup parent) {
        // TODO Auto-generated method stub
        Typeface custom_regular = Typeface.createFromAsset(activity.getAssets(),
                "fonts/OpenSans-Regular.ttf");

        if (inflater == null)
            inflater = (LayoutInflater) activity
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        if (convertView == null)
            convertView = inflater.inflate(R.layout.recharge_listitem, null);

        TextView   orderitemid_delete=(TextView)convertView.findViewById(R.id.orderitemid);
        TextView accountnumber = (TextView) convertView
                .findViewById(R.id.accountnumber);
        TextView servicename = (TextView) convertView
                .findViewById(R.id.servicetypname);
        TextView planamount = (TextView) convertView
                .findViewById(R.id.rechargeamount);
        final ImageView close = (ImageView) convertView
                .findViewById(R.id.crosse_close_img);
        accountnumber.setTypeface(custom_regular);
        servicename.setTypeface(custom_regular);
        planamount.setTypeface(custom_regular);
        //orderitemid = bpData.get(position).getOrderitemID();
        // Log.v("TAG_orderitemid",""+orderitemid);
        orderid = bpData.get(position).getOrderid();

        final LinearLayout layoutrecharge = (LinearLayout) convertView.findViewById(R.id.rechargelay);
        layoutrecharge.setTag(position);


        accountnumber.setText(bpData.get(position).getAccountNumber());
        servicename.setText(bpData.get(position).getServicename());
        planamount.setText("Rs." + bpData.get(position).getRechargeamount());
        orderitemid_delete.setText(bpData.get(position).getOrderitemID());


        totalamount.setText("Rs " + bpData.get(position).getAmount());
        layoutrecharge.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {


                new GetdeleteOrderItem().execute(WebUrl.RechargeServiceURL + "deleteOrderItem");
                //int deletePos = Integer.parseInt(v.getTag().toString());

                TextView orderitemid_delete = (TextView)layoutrecharge
                        .findViewById(R.id.orderitemid);
                orderitemidfordelete = orderitemid_delete.getText().toString();
                int deletePos = Integer.parseInt(v.getTag().toString());
                bpData.remove(deletePos);




                Helper.getListViewSize(recharge_lv);//run it
                notifyDataSetChanged();
                reloadcas_cb.setChecked(false);

            }
        });

        return convertView;
    }

error:

请先将您的操作放在asyncTask onPostExecute中并尝试执行以下操作：

yourAdaptersList.remove(positionToRemove);
yourAdapter = new Adapter(yourAdaptersList);
yourListView.setAdapter(yourAdapter);

如何在android中删除自定义列表视图适配器中的完整布局？
