如何在Android中的片段中使用Tab布局

Question

我的活动中有两个片段。这工作正常。现在在我的一个片段中，我需要两个选项卡式内容。而在每个标签中，我需要夸大一个视图。我怎么能在oncreateview方法中做到这一点？可能吗？

这里是我的XML布局：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="300dp" 
android:layout_height="match_parent" 
android:background="@drawable/texture_background" 
android:baselineAligned="false" 
android:orientation="vertical" > 

<LinearLayout 
    android:layout_width="match_parent" 
    android:layout_height="60dp" 
    android:background="#000" > 

    <TextView 
     android:layout_width="wrap_content" 
     android:layout_height="60dp" 
     android:layout_marginBottom="10dp" 
     android:padding="10dp" 
     android:text="header" 
     android:textColor="#fff" 
     android:textSize="25dp" > 
    </TextView> 
</LinearLayout> 
<TabHost 
    android:id="@android:id/tabhost" 
    android:layout_width="fill_parent" 
    android:layout_height="fill_parent" > 

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

     <TabWidget 
      android:id="@android:id/tabs" 
      android:layout_width="fill_parent" 
      android:layout_height="wrap_content" 
      android:visibility="gone" /> 

     <FrameLayout 
      android:id="@android:id/tabcontent" 
      android:layout_width="fill_parent" 
      android:layout_height="fill_parent" /> 
    </LinearLayout> 
</TabHost> 
</LinearLayout> 

这里是我的片段内oncreateview方法。

public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    View view = inflater.inflate(R.layout.saved_deals_fragment, container,false); 
    TabHost tabs=(TabHost)view.findViewById(android.R.id.tabhost); 
    tabs.setup(); 
    TabHost.TabSpec tab = tabs.newTabSpec("my tab content"); 
    tab.setIndicator("my tab content"); 
    tabs.addTab(tab); 
    return view; 
} 

这是我的错误：

我是否需要提供任何其他细节？

Answer 1

您不提供标签的内容。你可以使用一个TabContentFactory建立这样的内容：

TabHost.TabSpec tab = tabs.newTabSpec("tab1"); 
tab.setIndicator("my tab content"); 
tab.setContent(new TabHost.TabContentFactory() { 

      @Override 
      public View createTabContent(String tag) { 
       if (tag.equals("tab1")) { 
        // create/inflate the view for the tab 1 
        return view; 
       } else { 
        // the same as tab 1 for the other tabs if you have any    
      } 
     }); 
tabs.addTab(tab);
