            View view = null;
            if(tag.equals("tabOneSpec"))
            {
                try
                {
                    //static final String[] FRUITS = new String[] { "Apple", "Avocado", "Banana",

How to add ListActivity in this TabActivity

Answer 1

Often times when creating an activity with tabs,
it’s easy to have a separate activity for the tab content.
However, things get tricky when those activities need to
interact with one another.

So the solution is to create a tabactivity with views
(instead of activities) as the tab content.
To create the TAB, there are a few steps we need to follow:

1. create the tabHost and set its parameters
2. create the tabWidget, the container for the clickable tabs
3. create a frameLayout, to hold the views associated to each tab
4. create each tab, using the tabSpec class
