Android add Tabs from other xml Layouts

The big question which made fire my crazy is: how to add tabs to the TabHost from other xml layouts?

I searched and searched much times and finally I tried something and I had succeed.

The Step to have tabs from other xml layouts:
1- Add tab host to your layout -main_window-
2- Create your separate XML layout file
3- Inflate it to view in java code.
4- Override createTabContent and return the inflated view.
5- Add the view to the TabSpec.
Look @ the code bellow

setContentView(R.layout.main_window);
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext()
.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
final View row = layoutInflater.inflate(R.layout.mySeperatedXMLLayout,null);
ListView leftList = (ListView) row.findViewById(R.id.leftList);
leftList .setAdapter(new IconAndTextListAdapter(getBaseContext(),
R.layout.icon_and_text, new Contents()
.getCountriesFlagsLinks("en"), new Contents()
.getCountriesNames("en"), R.id.icon_view,
R.id.text_view));

ListView categoriesList = (ListView) row.findViewById(R.id.rightList);
categoriesList.setAdapter(new IconAndTextListAdapter(getBaseContext(),
R.layout.icon_and_text, new Contents()
.getCountriesFlagsLinks("en"), new Contents()
.getCountriesNames("en"), R.id.icon_view,
R.id.text_view));

TabHost tabHost = (TabHost) findViewById(android.R.id.tabhost);
tabHost.setup();
TabSpec setContent = tabHost.newTabSpec("Tab1")
.setIndicator("Countries").setContent(new TabHost.TabContentFactory() {
public View createTabContent(String tag) {
return row;
}});
tabHost.addTab(setContent);
