如何在片段中添加tabhost

Question

我想在片段中添加tabhost，但无论我尝试什么，我都无法插入它。我可能会在这里错过一些基础知识。下面是我的类TabFragment的代码。它返回一个视图。

public class TabFragment extends Fragment{ 

    public void onCreate(Bundle savedInstanceState) 
    { 
     super.onCreate(savedInstanceState); 
    } 
    private TabHost mTabHost; 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) 
    { 
      View view = inflater.inflate(R.layout.tabmain, container, false); 
      mTabHost = (TabHost) view.findViewById(android.R.id.tabhost); 
      mTabHost.setup();//very important to call this 
      TabHost.TabSpec tab = mTabHost.newTabSpec("my tab content"); 
      tab.setIndicator("my tab content"); 
      mTabHost.addTab(tab); 
     return view; 
    } 
}

随着API级别17，这是现在可以：

import android.support.v4.app.Fragment; 
import android.support.v4.app.FragmentTabHost; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 

// This class is the 3rd fragment in my ViewPager, 
// to which I wanted to add 2 tabs.... 
public class TabHostParentFragment extends Fragment { 
private FragmentTabHost mTabHost; 

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

Bundle arg1 = new Bundle(); 
arg1.putInt("Arg for Frag1", 1); 
mTabHost.addTab(mTabHost.newTabSpec("Tab1").setIndicator("Frag Tab1"), 
    MyNestedFragment1.class, arg1); 

Bundle arg2 = new Bundle(); 
arg2.putInt("Arg for Frag2", 2); 
mTabHost.addTab(mTabHost.newTabSpec("Tab2").setIndicator("Frag Tab2"), 
    MyNestedFragment2.class, arg2); 

return mTabHost; 
} 

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

确保您更新Android的支持，v4.jar文件，因为它没有自动更新我，当我通过下载SDK经理。这可以防止定义getChildFragmentManger()函数。
