无法通过活动组加载标签活动

Question

我想通过活动组活动加载到一个选项卡，但该活动并非负荷达到高潮在一个IllegalStateException错误：

这里是日志的副本信息：

java代码读取包含tabhost和tabwidget控制xml文件：

public class tabs extends Activity{ 


     protected void onCreate(Bundle savedInstanceState) { 

      super.onCreate(savedInstanceState); 
      setContentView(R.layout.tabmain); 

      TabHost tabs=(TabHost)findViewById(R.id.tabhost); 

      tabs.setup(); 

      TabHost.TabSpec spec=tabs.newTabSpec("tag1");  
      spec.setContent(R.id.tab1); 
      spec.setIndicator("tab1"); 
      tabs.addTab(spec); 

      spec=tabs.newTabSpec("tag2"); 
      spec.setContent(R.id.tab2); 
      spec.setIndicator("tab2"); 
      tabs.addTab(spec); 

      spec=tabs.newTabSpec("tag3"); 
      spec.setIndicator("Favourites", getResources().getDrawable(R.drawable.favourites_star)); 
      spec.setContent(new Intent(this,RadioAppActivityGroup.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)); 
      tabs.addTab(spec); 

     } 


    private class RadioAppActivityGroup extends ActivityGroup{ 


     protected void onCreate(Bundle savedInstanceState) { 

      super.onCreate(savedInstanceState); 

      View view = getLocalActivityManager().startActivity("radiotabs", new 
      Intent(this, favourites.class).addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP)).getDecorView(); 

      this.setContentView(view); 


     } 



    } 


} 

XML代码方含的tabhost和布局控制：

<?xml version="1.0" encoding="utf-8"?> 
<TabHost xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+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 
     android:id="@+id/tab1" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:orientation="vertical"/> 

     <LinearLayout 
     android:id="@+id/tab2" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:orientation="vertical"/> 

     <LinearLayout 
     android:id="@+id/tab3" 
     android:layout_width="fill_parent" 
     android:layout_height="fill_parent" 
     android:orientation="vertical"/> 

    </FrameLayout> 
    </LinearLayout> 
</TabHost> 

Answer 1

首先阅读this official document of Tab Layout，之后提高代码

Answer 2

而不是调用tabs.setup的（）;

试试下面的那个地方

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

线同时，尽量使RadioAppActivityGroup独立的类继承的ActivityGroup，而不是使其成为私有内部类，并在清单ASLO定义它。
