我試圖使用Android支持v4庫中的片段/選項卡和尋呼機來構建應用程序。我想讓我的應用程序android 2.3兼容,但我有問題。它在屏幕截圖中可見:標籤名稱包裝。我想要大約20-40個選項卡,並且能夠使用滑動進行導航(如市場應用程序中所示)。Android片段/選項卡和尋呼機:選項卡名稱包裝

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 

    setContentView(R.layout.fragment_tabs_pager); 
    mTabHost = (TabHost)findViewById(android.R.id.tabhost); 
    mTabHost.setup(); 

    mViewPager = (ViewPager)findViewById(R.id.pager); 

    mTabsAdapter = new TabsAdapter(this, mTabHost, mViewPager); 

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

    if (savedInstanceState != null) { 
     mTabHost.setCurrentTabByTag(savedInstanceState.getString("tab")); 
    } 
} 

XML

<TabHost 
    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"

     <TabWidget

      android:layout_width="match_parent" 
      android:layout_height="wrap_content" 
      android:layout_weight="0"/> 

     <FrameLayout

      android:layout_width="0dp" 
      android:layout_height="0dp" 
      android:layout_weight="0"/> 

     <android.support.v4.view.ViewPager 
      android:id="@+id/pager" 
      android:layout_width="match_parent" 
      android:layout_height="0dp" 
      android:layout_weight="1"/> 

    </LinearLayout> 
</TabHost>
