Use the tab [Android entry 6]

========================================================== ====================================
1. Add a button to the main activity and use the button to jump to the tab.

Private button tabviewbutton = NULL; Public void oncreate (bundle savedinstancestate) {super. oncreate (savedinstancestate); setcontentview (R. layout. main); tabviewbutton = (button) findviewbyid (R. id. tabviewbutton); tabviewbutton. setonclicklistener (New tabviewbuttonlistener ();} // use the intent object to switch to class tabviewbuttonlistener implements onclicklistener {public void onclick (view arg0) in the activity of the tab) {// todo auto-generated method stub intent = new intent (); intent. setclass (tabviewtest. this, tabviewdemo. class); tabviewtest. this. startactivity (intent );}}

2. Create a tab layout file, tab_value.xml

<Framelayout xmlns: Android = "http://schemas.android.com/APK/RES/android" Android: layout_width = "fill_parent" Android: layout_height = "fill_parent"> <textview Android: id = "@ + ID/view1" Android: layout_width = "fill_parent" Android: layout_height = "wrap_content" Android: TEXT = "This is the first tab label"/> <textview Android: Id = "@ + ID/view2" Android: layout_width = "fill_parent" Android: layout_height = "wrap_content" Android: text = "this is the second tab label"/> <textview Android: Id = "@ + ID/view3" Android: layout_width = "fill_parent" Android: layout_height = "wrap_content" Android: text = "this is the third tab label"/> </framelayout>

3. Create a tab activity,
 
 

  protected void onCreate(Bundle savedInstanceState) { // TODO Auto-generated method stub    super.onCreate(savedInstanceState);           setTitle("TabViewDemo");           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)); }

4. register the tab activity in adroidmanifest. xml.

   <activity android:name=".TabViewDemo"                  android:label="@string/app_view">   </activity>
