Android下实现TabActivity

activity继承自TabActivity

public class TabActivityDemo extends TabActivity {

@Override

public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setTitle("TabDemoActivity");

TabHost tabHost = getTabHost();

LayoutInflater.from(this).inflate(R.layout.tab_demo,

tabHost.getTabContentView(),true);

tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("tab1").setContent(R.id.view1));

tabHost.addTab(tabHost.newTabSpec("tab2").setIndicator("tab2").setContent(R.id.view2));

tabHost.addTab(tabHost.newTabSpec("tab3").setIndicator("tab3").setContent(R.id.view3));

}

}

tab_demo.xml

<?xml version="1.0" encoding="utf-8"?>
