Tab标签的使用【安卓入门六】

=======================================================================
1、在主activity中添加一个Button按钮，利用按钮跳转到Tab标签中

 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对象转到tab标签的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的布局文件，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="这个是第一个Tab标签"
     />
     <TextView  
     android:id="@+id/view2"
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:text="这个是第二个Tab标签"
     />
    <TextView  
     android:id="@+id/view3"
     android:layout_width="fill_parent" 
     android:layout_height="wrap_content" 
     android:text="这个是第三个Tab标签"
     />
</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中注册Tab的activity。

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