Android：将gridview添加为listview的标题

Question

我正在尝试添加日历的gridview作为listview的标题视图。它工作得很好，gridview完美展现。但现在问题是我无法点击日期！我不知道自己做错了什么.. rLayout是我的列表视图。 这是我的代码：

gridview= new GridView(getActivity());
    AbsListView.LayoutParams gridParams= new AbsListView.LayoutParams(AbsListView.LayoutParams.MATCH_PARENT, (int)(height/2.5));
    gridview.setLayoutParams(gridParams);
    gridview.setNumColumns(7);
    gridview.setStretchMode(GridView.STRETCH_COLUMN_WIDTH);

  gridview.setOnItemClickListener(new OnItemClickListener() {
        public void onItemClick(AdapterView<?> parent, View v,
                int position, long id1) {
            if(rLayout.getAdapter() == null){

            }else{
                rLayout.invalidate();

            }
       //some code

    });
    rLayout.addHeaderView(gridview);

这是我的xml文件：
