Just use .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP) to your tab class

Example

 tabHost.addTab(tabHost.newTabSpec("Your Tab")
        .setIndicator("tab indicator")
        .setContent(new Intent(this, TabClass.class)
        .addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)));

You can use onWindowFocusChanged method also if you need to do add some more process when getting the focus for a particular tab..

@Override
    public void onWindowFocusChanged(boolean hasFocus) {
        // TODO Auto-generated method stub

        //You can add your own method to refresh data within the tab                 //(Ex:  refreshData())

super.onWindowFocusChanged(hasFocus);

}
