片段內的SlidingMenu

我試圖在片段內包含SlidingMenu。之所以我想將SlidingMenu放入片段中，是因爲我的viewPager的一個頁面會顯示它。只是因爲其中一個示例擴展了SlidingFragmentActivity而使我對擴展片段感到困惑。片段內的SlidingMenu

public class Activity A extends SlidingFragmentActivity {}

我一直在嘗試這樣的，

public class ResponsiveUIActivityE extends SherlockFragment{ 

    View rootView; 
    private Fragment mContent; 

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

      SlidingFragmentActivity2 sl = new SlidingFragmentActivity2(); 



      getActivity().setTitle("R.string.responsive_ui"); 
      LayoutInflater vi = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
      rootView = vi.inflate(R.layout.two_fragments, null, false); 

     // check if the content frame contains the menu frame 
      if (rootView.findViewById(R.layout.two_fragments) == null) { 
       //sl.setBehindContentView(R.layout.two_fragments); 
       sl.getSlidingMenu().setSlidingEnabled(true); 
       sl.getSlidingMenu().setTouchModeAbove(SlidingMenu.TOUCHMODE_FULLSCREEN); 
       // show home as up so we can toggle 


      } else { 

      } 

      // set the Above View Fragment 
      if (savedInstanceState != null){ 
       mContent = getChildFragmentManager().getFragment(savedInstanceState, "mContent"); 
      if (mContent == null) 
       mContent = new BirdGridFragment(0); 
      getChildFragmentManager() 
      .beginTransaction() 
      .replace(R.id.content_frame, mContent) 
      .commit(); 

      // set the Behind View Fragment 
      getChildFragmentManager() 
      .beginTransaction() 
      .replace(R.id.menu_frame, new BirdMenuFragment()) 
      .commit(); 

      // customize thse SlidingMenu 
      SlidingMenu sm = sl.getSlidingMenu(); 
      sm.setBehindOffsetRes(R.dimen.slidingmenu_offset); 
      sm.setShadowWidthRes(R.dimen.shadow_width); 
      sm.setShadowDrawable(R.drawable.shadow); 
      sm.setBehindScrollScale(0.25f); 
      sm.setFadeDegree(0.25f); 
      } 

     return rootView; 
     } 
}

你爲什麼要滑動菜單在slidingMenu裏面？如果你想在頁面中回收它裏面的視圖，你爲什麼不把視圖作爲一個片段放置在滑動菜單或頁面中？順便提一下，最後的支持庫版本可以使用標準的DrawerLayout。既然你現在正在執行它，我強烈建議你去標準:)。 –

我之所以選擇slidingMenu庫是因爲我有一個現有的例子。我不知道如何做DrawerLayout。我可以將DrawerLayout放入我的片段頁面之一嗎？謝謝 – rahstame

我看不出有什麼理由不能。最終它可以抽象爲一個ViewGroup，所以我想它會工作沒有問題。 http://developer.android.com/reference/android/support/v4/widget/DrawerLayout.html。這裏是DrawerLayout的文檔。 –

從上支持天秤座ry版本可以使用標準DrawerLayout。由於您正在實施它，我強烈建議您去標準而不是使用外部庫。

我看不出有任何理由爲什麼它should't一個ViewPager內工作。

這裏是official tutorial。
