在android中嵌套的ActionBar？

Question

有沒有辦法在Android中嵌套ActionBar？

我的意思是說..

當我按在選項卡菜單中tab buttons之一，我想告訴另一sub-menu tabs主菜單

下面是可能的嗎？如果你能爲我提供的例子，請..

在此先感謝

Answer 1

import com.example.android.supportv4.R; 
import android.os.Bundle; 
import android.support.v4.app.FragmentActivity; 
import android.support.v4.app.FragmentTabHost; 

public class FragmentTabs extends FragmentActivity 
{ 
    private FragmentTabHost mTabHost; 

    @Override 
    protected void onCreate(Bundle savedInstanceState) { 

     super.onCreate(savedInstanceState); 


     setContentView(R.layout.fragment_tabs); 
     mTabHost = (FragmentTabHost)findViewById(android.R.id.tabhost); 
     mTabHost.setup(this, getSupportFragmentManager(), R.id.realtabcontent); 

     mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"), 
       FragmentStackSupport.CountingFragment.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Contacts"), 
       LoaderCursorSupport.CursorLoaderListFragment.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("custom").setIndicator("Custom"), 
       LoaderCustomSupport.AppListFragment.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("throttle").setIndicator("Throttle"), 
       LoaderThrottleSupport.ThrottledLoaderListFragment.class, null); 
    } 
} 

這也可以一個片段內通過片段嵌套使用：

import com.example.android.supportv4.R; 
import android.os.Bundle; 
import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentTabHost; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 


public class FragmentTabsFragmentSupport extends Fragment { 
    private FragmentTabHost mTabHost; 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 
     mTabHost = new FragmentTabHost(getActivity()); 
     mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.fragment1); 

     mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple"), 
       FragmentStackSupport.CountingFragment.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("contacts").setIndicator("Contacts"), 
       LoaderCursorSupport.CursorLoaderListFragment.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("custom").setIndicator("Custom"), 
       LoaderCustomSupport.AppListFragment.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("throttle").setIndicator("Throttle"), 
       LoaderThrottleSupport.ThrottledLoaderListFragment.class, null); 

     return mTabHost; 
    } 

    @Override 
    public void onDestroyView() { 
     super.onDestroyView(); 
     mTabHost = null; 
    }}
