如何填充GridView中的空单元格并使其不可点击

public class MyGridViewAdapter extends BaseAdapter {
    private List<String> mDataList;
    private Context mContext;

    public MyGridViewAdapter(List<String> dataList, Context context) {
        mDataList = dataList;
        mContext = context;
    }

    @Override
    public int getCount() {
        return mDataList.size();
    }

    @Override
    public Object getItem(int position) {
        return mDataList.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder viewHolder;
        if (convertView == null) {
            convertView = LayoutInflater.from(mContext).inflate(R.layout.gridview_item, parent, false);
            viewHolder = new ViewHolder();
            viewHolder.textView = convertView.findViewById(R.id.textview);
            convertView.setTag(viewHolder);
        } else {
            viewHolder = (ViewHolder) convertView.getTag();
        }

        String data = mDataList.get(position);
        if (data.isEmpty()) {
            // 当数据为空时，创建一个不可点击的空视图
            convertView.setClickable(false);
            convertView.setFocusable(false);
            viewHolder.textView.setText("");
            viewHolder.textView.setBackgroundColor(Color.TRANSPARENT);
        } else {
            // 当数据不为空时，显示数据
            convertView.setClickable(true);
            convertView.setFocusable(true);
            viewHolder.textView.setText(data);
            viewHolder.textView.setBackgroundColor(Color.WHITE);
        }

        return convertView;
    }

    static class ViewHolder {
        TextView textView;
    }
}

List<String> dataList = new ArrayList<>();
// 填充数据源，包括空数据和非空数据
dataList.add("数据1");
dataList.add("");
dataList.add("数据3");
// ...
GridView gridView = findViewById(R.id.gridview);
MyGridViewAdapter adapter = new MyGridViewAdapter(dataList, this);
gridView.setAdapter(adapter);
gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
        String data = dataList.get(position);
        if (!data.isEmpty()) {
            // 执行相关点击操作
            // ...
        }
    }
});
