TabDemo in Android

First the style, note must use Android:id/tabs cannot use id+

<tabhost android:layout_height= "match_parent"    android:layout_width= "match_parent"    android:id= "@ Android:id/tabhost "     xmlns:android=" http://schemas.android.com/apk/res/android ">    <linearlayout    android:layout_width= "match_parent"    android:layout_height= "match_parent"    android:orientation= " Vertical ">    <tabwidget         android:layout_width=" match_parent "        android:layout_height=" Wrap_ Content "        android:id=" @android: Id/tabs "        >    </TabWidget>    <framelayout android:id=" @android: id/tabcontent "        android:layout_width=" match_parent "        android:layout_height=" Wrap_content "        android:layout_weight= "1"        >    </FrameLayout></LinearLayout></TabHost>

　　

Next write the Code

public class Tabactivity extends Android.app.TabActivity {private tabhost _tabhost; @Overrideprotected void OnCreate ( Bundle savedinstancestate) {//TODO auto-generated method Stubsuper.oncreate (savedinstancestate); Setcontentview ( R.layout.activity_tab); _tabhost=gettabhost ();} private void AddTab1 () {//TODO auto-generated method stubintent intent1=new Intent (this,activity1.class); Tabspec sp1=_tabhost.newtabspec ("option 1");//Jump to Sp1.setcontent (intent1);//title Sp1.setindicator ("one"); _tabhost.addtab ( SP1);}}
