There are many different ways to do this, however I recommend doing a few changes.

First off, use a ListView element, apposed to doing ListActivity, check out this example.

Then I would suggest playing around with ViewFlipper, you can set animations to flip between the different view elements, how they work is they have a hierarchy of view elements, which can only show one at a time, so what you would do is, for example,

<ViewFlipper
      .... >

    <ListView
         ... >

    <ListView
         ... >

    <ListView
         ... >

</ViewFlipper>

When you get the View Flipper in your main Activity, you will set the displayed view, and as you set 0,1,2 it will flip between the list views, for example 0 could be main screen, 1 theaters, 2 restaurants, etc

Simple you can use context menu for your list, but it just fired for long click event. For example:

  registerForContextMenu(listView);
