Unless I'm mistaken, you're using gender.xml as the layout for each row/item in the ListView. So, you'll probably want to remove the Button declaration from gender.xml layout.

If you want the Button to be fixed above the ListView, then you probably want to edit the layout that declares the ListView to also declare the Button, assuming you have such an xml layout.

For example, the xml layout with the ListView might then look something like the following.

<LinearLayout orientation="horizontal">
    <Button 
        id="my_button"
        width="wrap_content"
        height="wrap_content"
        layout_gravity="center"
        text="my button" />
    <ListView 
        id="my_listview"
        width="fill_parent"
        height="0dip"
        weight="1" />
</LinearLayout>

(Note: This xml layout is not complete, and is missing pieces, such as the xmlns declaration. For a more complete example, take a look at Scrolling Text Above Buttons, Buttons Fixed At Bottom.)

You can also add header to the list view:

Button btn=new Button(this);
list.addHeaderView(btn);

this will make butten the first item of your listview

You can also make it not selectable by

list.addHeaderView(vbtn, null, false);

And sent an onItemClickListener.
