Tab標籤的使用【安卓入門六】

=======================================================================
1、在主activity中添加一個Button按鈕，利用按鈕跳轉到Tab標籤中
   
  

 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());    }     //利用intent對象轉到tab標籤的activity中     class tabViewButtonListener implements OnClickListener{  public void onClick(View arg0) {             // TODO Auto-generated method stub      Intent intent = new Intent();      intent.setClass(TabViewTest.this, TabViewDemo.class);      TabViewTest.this.startActivity(intent);  }         }

2、建立Tab的布局檔案，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="這個是第一個Tab標籤"     />     <TextView       android:id="@+id/view2"     android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:text="這個是第二個Tab標籤"     />    <TextView       android:id="@+id/view3"     android:layout_width="fill_parent"      android:layout_height="wrap_content"      android:text="這個是第三個Tab標籤"     /></FrameLayout>

3、建立Tab的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、在AdroidManifest.xml中註冊Tab的activity。
 

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