Fragment - getting fancy - detecting tab changes

gistfile1.java

// Listener to detect when a tab has changed. I added this just to show 
// how you can change UI to emphasize the selected tab
tabHost.setOnTabChangedListener(new OnTabChangeListener() {
    @Override
    public void onTabChanged(String tag) {
        // reset some styles
        clearTabStyles();
        View tabView = null;
        // Use the "tag" for the tab spec to determine which tab is selected
        if (tag.equals("home")) {
            tabView = getTabWidget().getChildAt(0);
        }
        else if (tag.equals("users")) {
            tabView = getTabWidget().getChildAt(1);
        }
        tabView.findViewById(R.id.tabSelectedDivider).setVisibility(View.VISIBLE);
    }       
});
