The following activity has only one textview. Click it to enter the tabactivity.

Package com. Test. WWW;

Import Android. App. activity;
Import Android. content. intent;
Import Android. OS. Bundle;
Import Android. View. view;
Import Android. View. View. onclicklistener;
Import Android. widget. textview;

Public class tablehostactivity extends activity {
/** Called when the activity is first created .*/
@ Override
Public void oncreate (bundle savedinstancestate ){
Super. onCreate (savedInstanceState );
// SetContentView (R. layout. main );
TextView TV = new TextView (this );
TV. setText ("table host! ");
TV. setTextSize (30 );
TV. setOnClickListener (new OnClickListener (){

Public void onClick (View v ){
// TODO Auto-generated method stub
Startactivity (new intent (tablehostactivity. This, activitytablehost. Class ));
Finish ();
}
});
Setcontentview (TV );
}
}

The following is tabactivity (the activity of the tab inherits this class). Click textview in this class to display the title of the tab on another interface,

Package com. Test. WWW;

Import com. Test. www. R;

Import Android. App. tabactivity;
Import Android. content. intent;
Import Android. content. res. Resources;
Import Android. OS. Bundle;
Import Android. util. log;
Import Android. widget. tabhost;
Import android. widget. TabHost. OnTabChangeListener;

Public class ActivitytableHost extends TabActivity {
@ Override
Protected void onCreate (Bundle savedInstanceState ){
// TODO Auto-generated method stub
Super. onCreate (savedInstanceState );
SetContentView (R. layout. main );
Resources res = getResources ();

TabHost tabHost = getTabHost ();
// Spec statement, speculative
TabHost. TabSpec spec;

Intent intent;
// Indicator
Intent = new intent (this, activityinside. Class). putextra ("show", "Tab 1"); // pass the value to the startup Interface
// Name; characters to be displayed; animation settings
Spec = tabhost. newtabspec ("A1"). setindicator ("A1", res. getdrawable (R. drawable. C1 ))
. Setcontent (intent); // set an acitivity

Tabhost. addtab (SPEC );

Intent = new intent (this, activityinside. Class). putextra ("show", "Tab 2 ");

Spec = tabHost. newTabSpec ("a2"). setIndicator ("a2", res. getDrawable (R. drawable. c1 ))
. SetContent (intent );

TabHost. addTab (spec );

Intent = new Intent (this, ActivityInside. class). putExtra ("show", "tab 3 ");

Spec = tabHost. newTabSpec ("a3"). setIndicator ("a3", res. getDrawable (R. drawable. c1 ))
. SetContent (intent); // The name and icon of the tab

Tabhost. addtab (SPEC );

Intent = new intent (this, activityinside. Class). putextra ("show", "tab 4 ");

Spec = tabhost. newtabspec ("A4"). setindicator ("A4", res. getdrawable (R. drawable. C1 ))
. Setcontent (intent );

Tabhost. addtab (SPEC );

Tabhost. setcurrenttab (2); // give an initial value, pointing to this position

Tabhost. setontabchangedlistener (New ontabchangelistener (){

Public void ontabchanged (string Tabid ){
// Todo auto-generated method stub

}
});
}
}
This is the tab page that displays the tabhost tab. Click the tab title above to display the tab. The program exits.

}
});
TV. setText (getIntent (). getStringExtra ("show "));
SetContentView (TV );
