<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"  
	android:id="@+id/hometabs"
	android:orientation="vertical"
    android:layout_width="fill_parent"  
    android:layout_height="fill_parent">
    <!-- TabHost必须包含一个 TabWidget和一个FrameLayout--> 
    <TabHost android:id="@+id/tabhost"
     	android:layout_width="fill_parent"
     	android:layout_height="wrap_content"
     	>
     	<LinearLayout
			android:orientation="vertical"
			android:layout_width="fill_parent"
			android:layout_height="fill_parent">

	     	<TabWidget android:id="@android:id/tabs"

			    	<TextView android:id="@+id/view2"
				        android:layout_width="fill_parent"

			    	<TextView android:id="@+id/view3"
				        android:layout_width="fill_parent"
				        android:layout_height="fill_parent"/>
		     </FrameLayout>
	     
	     </LinearLayout>
    </TabHost>
</LinearLayout>

 

 

 

public class TagHostTest2 extends Activity {
	@Override
	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		// 获取TabHost对象
		TabHost tabHost = (TabHost) findViewById(R.id.tabhost);
		// 如果没有继承TabActivity时,通过该种方法加载启动tabHost
		tabHost.setup();
		tabHost.addTab(tabHost.newTabSpec("tab1").setIndicator("第一个标签",
				getResources().getDrawable(R.drawable.icon)).setContent(
				R.id.view1));

}

 

 

 

其中,.setContent(R.id.view2)) 可传入intent参数,此时 应该继承acitivityGroup,

public class TabMergeActivity extends TabActivity{
    @Override
    public void onCreate(Bundle savedInstanceState) { 
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
     TabHost tabHost = getTabHost();  
     TabSpec spec;
     Resources res = getResources(); 
     Intent intent;   
 
   //第一个TAB
     intent = new Intent(this,A.class);  
     spec = tabHost.newTabSpec("tab1") 
     .setIndicator("Tab1", res.getDrawable(android.R.drawable.ic_media_play)) 
     .setContent(intent); 
     tabHost.addTab(spec);
