Here is a nice tutorial of TabActivity you are looking for,

Tab Example

For changing the icon of selected tab you have to create an xml for each tab like this in drawable folder

first_tab.xml

    <item android:state_selected="false"        
          android:drawable="@drawable/tab_unselected_icon"/>
    <item android:state_selected="true"        
          android:drawable="@drawable/tab_selected_icon"/>
</selector>

And the while creating tabs you have to use this xml like this,

intent = new Intent().setClass(this, Activity_name.class);
        spec = tabHost.newTabSpec("yourTab_name").setIndicator("yourTab_name",res.getDrawable(R.drawable. first_tab)).setContent(intent);
        tabHost.addTab(spec);

And you are done with it. Thanks.
