Core code:

Package com. tabhost; import android. OS. bundle; import android. app. activity; import android. app. activityGroup; import android. content. intent; import android. view. menu; import android. view. window; import android. widget. tabHost; public class MainActivity extends ActivityGroup {private TabHost mTabHost; protected void onCreate (Bundle savedInstanceState) {super. onCreate (savedInstanceState); this. requestWindowFeature (Window. FEATURE_NO_TITLE); setContentView (R. layout. activity_main); // set TabHost initTabs ();} private void initTabs () {mTabHost = (TabHost) findViewById (R. id. tabhost); mTabHost. setup (this. getLocalActivityManager (); // Add the log List tab. Pay attention to the Code in the following setContent. mTabHost is the key to achieving this requirement. addTab (mTabHost. newTabSpec ("tab_log "). setIndicator ("log", getResources (). getDrawable (R. drawable. login_bg )). setContent (new Intent (this, LogActivity. class); // Add the application settings tab. Pay attention to the Code in the following setContent. mTabHost is the key to achieving this requirement. addTab (mTabHost. newTabSpec ("tab_setting "). setIndicator ("set", getResources (). getDrawable (R. drawable. ic_launcher )). setContent (new Intent (this, SettingActivity. class); mTabHost. setCurrentTab (1 );}}

The two sub-pages are simple, with two activities and corresponding la S.
