在Android中添加Fragment內的Tab？

Question

我想在片段內添加一個TabHost。代碼如下。這裏面的碎片。我想補充TabHost顯示兩個標籤：

package com.nordicsoft.dilosysNewVersion; 

import android.app.Fragment; 
import android.content.Intent; 
import android.os.Bundle; 
import android.view.LayoutInflater; 
import android.view.View; 
import android.view.ViewGroup; 
import android.widget.TabHost; 

public class Fragment_Coupons extends Fragment { 
    TabHost tabHost; 
    TabHost.TabSpec spec; 

    public Fragment_Coupons() { 
    } 

    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     View rootView = inflater.inflate(R.layout.fragment_coupon, container, 
       false); 
     tabHost = (TabHost) rootView.findViewById(android.R.id.tabhost); 
     tabHost.setup(); 
     //Add_Text_To_Tab("Android", "IOS"); 

     Intent intentAndroid = new Intent().setClass(getActivity(), 
       Aclass.class); 
     spec = tabHost.newTabSpec("Android").setContent(intentAndroid) 
       .setIndicator("Android"); 

     tabHost.addTab(spec); 

     Intent intentBus = new Intent().setClass(getActivity(), Bclass.class); 
     spec = tabHost.newTabSpec("Welcome").setIndicator("Welcome") 
       .setContent(intentBus).setIndicator("Welcome"); 
     tabHost.addTab(spec); 
     return rootView; 
    } 

} 

的XML代碼：

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/tabhost" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent"> 
    <LinearLayout 
     android:orientation="vertical" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent"> 
     <TabWidget 
      android:id="@android:id/tabs" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" /> 
     <FrameLayout 
      android:id="@android:id/tabcontent" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent"/> 
    </LinearLayout> 
</TabHost> 

這是給我的錯誤：

Answer 1

嘗試加入這一行

tabHost.setup(this.getActivity().getLocalActivityManager()); 

前行

tabHost.addTab(spec); 

或嘗試加入：

LocalActivityManager mLocalActivityManager = new LocalActivityManager(this.getActivity(), false); 
mLocalActivityManager.dispatchCreate(savedInstanceState); 
host.setup(mLocalActivityManager); 

Answer 2

嘗試這樣做處理標籤：

public class MainFragment extends Fragment { 
    private FragmentTabHost mTabHost; 

    //Mandatory Constructor 
    public MainFragment() { 
    } 

    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 

    } 

    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
      Bundle savedInstanceState) { 

     View rootView = inflater.inflate(R.layout.fragment_tabs,container, false); 


     mTabHost = (FragmentTabHost)rootView.findViewById(android.R.id.tabhost); 
     mTabHost.setup(getActivity(), getChildFragmentManager(), R.id.realtabcontent); 

     mTabHost.addTab(mTabHost.newTabSpec("fragmentb").setIndicator("Fragment B"), 
       FragmentB.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("fragmentc").setIndicator("Fragment C"), 
       FragmentC.class, null); 
     mTabHost.addTab(mTabHost.newTabSpec("fragmentd").setIndicator("Fragment D"), 
       FragmentD.class, null); 


     return rootView; 
    } 
} 

的佈局：

<android.support.v4.app.FragmentTabHost 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@android:id/tabhost" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

    <LinearLayout 
     android:orientation="vertical" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

     <FrameLayout 
      android:id="@+id/realtabcontent" 
      android:layout_width="match_parent" 
      android:layout_height="0dp" 
      android:layout_weight="1"/> 

    </LinearLayout> 
</android.support.v4.app.FragmentTabHost> 

的MotherActivity舉辦MainFragment：

public class MotherActivity extends FragmentActivity { 

@Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 

     MainFragment fragmenttab = new MainFragment(); 
     getSupportFragmentManager().beginTransaction() 
     .add(R.id.item_detail_container, fragmenttab).commit(); 


    } 

而且MotherActivity佈局：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    xmlns:tools="http://schemas.android.com/tools" 
    android:id="@+id/item_detail_container" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
/> 

在此之後只創建正常片段B和C等類。 結果將是：
