I want to display the tab bar and listview but when my main activity launched then my tab bar gets hided... so tell me what is the problem in my xml or my src file.
My problem is: My tab bar is not showing and only listview is showing on the full screen.
Here my lisview appears first and behind that my tab bar slightly visible.
Main Activity:(Here I am displaying tab host)

setContentView(R.layout.layout_tab_bar);
// Get TabHost Refference
tabHost = getTabHost();
// Set TabChangeListener called when tab changed
tabHost.setOnTabChangedListener(this);
TabHost.TabSpec spec;
Intent intent;
/************* TAB1 (home)************/
// Create Intents to launch an Activity for the tab (to be reused)
intent = new Intent().setClass(this, HomeTab.class);
spec = tabHost.newTabSpec("First").setIndicator("")
.setContent(intent);
//Add intent to tab
tabHost.addTab(spec);

}
}
