You can get the size of your listview

listview.getCount();

then if it is equal to zero then change your button visibility

btnLoadMore.setVisibility(View.GONE);

Hide your footer like this :

// Firs check the list size is greater than 0:

if(s_oDataset.size > 0)
{
 // Add your footer here

}else
{
 // Dont not add your footer or Hide your footer
}
