Admob显示在标签布局的列表视图中

我有一个TabLayout，其中有一个ListView显示为意图.我想在此布局中放置一个admob横幅，但是它将遍历ListActivity和我之前定义的列表的最后一项.我该如何工作?

i have a TabLayout that has a ListView to show as intent. I would like to put an admob banner in this layout, but it goes over the ListActivity, over the last item of the list i defined before. How can i get this working?

现在发布main.xml:

Posting now the main.xml:
