当微调器在listview适配器中显示时，按钮无法隐藏

Question

我在适配器列表视图中有一个代码。我想在显示列表视图时隐藏“image2”按钮，但它不起作用。我的错在哪里？有人可以帮帮我吗？

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

        Database = new SQLite(context);
        db = Database.getReadableDatabase();

        if (convertView == null) {
            inflater = context.getLayoutInflater();
            convertView = inflater.inflate(resource, null);
        }

        final Model_CheckStock itempos = ListViewCheckStock.get(position);

        TextView txproduk = (TextView) convertView.findViewById(R.id.txproduk);
        final TextView txqty = (TextView) convertView.findViewById(R.id.txqty);
        final TextView txexpired = (TextView) convertView.findViewById(R.id.txexpired);
        TextView txidproduk = (TextView) convertView.findViewById(R.id.txidproduk);
        final Spinner spin = (Spinner) convertView.findViewById(R.id.spin);

        ImageView imgexpired = (ImageView) convertView.findViewById(R.id.imgexpired);
        Button image = (Button) convertView.findViewById(R.id.image);
        final Button image2 = (Button) convertView.findViewById(R.id.image2);

        txproduk.setText(ListViewCheckStock.get(position).gettxproduk());
        txidproduk.setText("Produk " + ListViewCheckStock.get(position).getjnsprod());
        txqty.setText(ListViewCheckStock.get(position).gettxqty());
        txexpired.setText(ListViewCheckStock.get(position).getexpired());

//        image2.setVisibility(View.INVISIBLE);
        if (txidproduk.getText().toString().contains("NON")) {
            Log.w("ADAPTERCHECKSTOCKLIST", "getView non: "+txidproduk.getText().toString() );
            List<Model_Unit> chekstok = Database.getUnitAll();
            ArrayAdapter<Model_Unit> dataAdapter = new ArrayAdapter<Model_Unit>(

            notifyDataSetChanged();
        } else {

我希望在列表视图显示时隐藏保存按钮（image2）。但按钮始终显示。

然后，当flagstatus不为0时，按钮仍会显示。
