1. Inflate any layout of your choice (this could be an XML of and ImageView with no drawable and with set height and width of your choice)
2. Measure the screen height and create new LayoutParams and set the height of it to 1/2 of the screen height
3. Set the new layout params on your inflated view
4. Use the ListView's addFooterView() method to add that view to the bottom of your list (there is also an addHeaderView())

Code to measure screen height

 WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
 Display display = wm.getDefaultDisplay();
 int screenHeight = display.getHeight();

Code to set half screen height:

 View layout = inflater.inflate(R.layout.mylistviewfooter, container, false);
 ViewGroup.LayoutParams lp = layout.getLayoutParams();
 lp.height = screenHeight/2;
 layout.setLayoutParams(lp);
 myListView.addFooterView(layout);

An Aside: When you add a footer or header view to any listview, it has to be done before adding the adapter. Also, if you need to get your adapter class after doing this you will need to know calling the listview's adapter by getAdapter() will return an instance of HeaderViewListAdapter in which you will need to call its getWrappedAdapter method Something like this :

 MyAdapterClassInstance myAdapter = (MyAdapterClassInstance) ((HeaderViewListAdapter) myListView.getAdapter()).getWrappedAdapter();
