Android的 - 使子選項卡機智TabHost

Question

是有可能創造由TabHost做出標籤子標籤？如果是這樣，怎麼樣？我沒能找到在這種情況下，任何有價值的資源或幫助。

感謝

有可能把一個TabActivity一個Tab內。

假設你有MainTabActivity兩個Tabs。首先Tab可以再抱FirstSubTabActivity和第二Tab可容納SecondSubTabActivity。

下面是一個例子：

主要活動：

public class MainTabActivity extends TabActivity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     TabHost tabHost = getTabHost(); 
     TabHost.TabSpec spec; 
     Intent intent; 

     intent = new Intent().setClass(this, FirstSubTabActivity.class); 
     spec = tabHost.newTabSpec("FirstTab").setIndicator("One").setContent(intent); 
     tabHost.addTab(spec); 

     intent = new Intent().setClass(this, SecondSubTabActivity.class); 
     spec = tabHost.newTabSpec("SecondTab").setIndicator("Two").setContent(intent); 
     tabHost.addTab(spec); 
    } 
} 

第一子活動：

public class FirstSubTabActivity extends TabActivity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     TabHost tabHost = getTabHost(); 
     TabHost.TabSpec spec; 
     Intent intent; 

     intent = new Intent().setClass(this, SomeActivity.class); 
     spec = tabHost.newTabSpec("SubTab").setIndicator("One").setContent(intent); 
     tabHost.addTab(spec); 

     intent = new Intent().setClass(this, SomeOtherActivity.class); 
     spec = tabHost.newTabSpec("AnotherSubTab").setIndicator("Two").setContent(intent); 
     tabHost.addTab(spec); 
    } 
} 

第二子活動：

個

public class SecondSubTabActivity extends TabActivity { 
    /** Called when the activity is first created. */ 
    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.main); 

     TabHost tabHost = getTabHost(); 
     TabHost.TabSpec spec; 
     Intent intent; 

     intent = new Intent().setClass(this, SomeThirdActivity.class); 
     spec = tabHost.newTabSpec("ThirdSubTab").setIndicator("One").setContent(intent); 
     tabHost.addTab(spec); 

     intent = new Intent().setClass(this, SomeFourthActivity.class); 
     spec = tabHost.newTabSpec("FourthSubTab").setIndicator("Two").setContent(intent); 
     tabHost.addTab(spec); 
    } 
}
