在我的mainActivity的片段中顯示ViewPager

Question

我是這裏的新成員。 我已經在我的問題上進行了兩次搜索，但是我還沒有找到任何東西。 所以我邀請你來尋求幫助。

我有抽屜式導航這是一類我想提出的是，當我滑向左或向右，我的日曆會出現一個不同的日期片段。 所以我開發了一個ViewPager片段。這個片段是我的導航抽屜的一個片段。 我的問題：查看頁面不顯示。

它要麼是顯示要麼是一個空白片段的頁面查看器。 它是代碼誰改變顯示的行：

mContext.setContentView(ViewPager); 

screen without this code screen with this code 「89」的數量是誰是1上划動遞增的隨機數。

的型動物部分代碼： 在主胡亞蓉展現片段：

TestSlideFragment fragment = new TestSlideFragment(); 
fragmentTransaction.replace(R.id.RelativeLayout_for_Fragment, fragment, fragment.getTag()); 
fragmentTransaction.commit(); 

testSlideFragment（Java和XML）

public class TestSlideFragment extends Fragment { 
    View view = null; 
    private static final int NUM_PAGES = 5; 
    int nbr = 0 ; 

    /** 
    * The pager widget, which handles animation and allows swiping horizontally to access previous 
    * and next wizard steps. 
    */ 
    private ViewPager mPager; 

    ViewPager ViewPager; 
    FragmentStatePagerAdapter mAdapt; 
    //private TabsAdapter d; 

    /** 
    * The pager adapter, which provides the pages to the view pager widget. 
    */ 
    private PagerAdapter mPagerAdapter; 


    public TestSlideFragment() { 
     // Required empty public constructor 
    } 


    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout for this fragment 



     view = inflater.inflate(R.layout.fragment_test_slide, container, false); 
     return view; 
    } 

    /** 
    * The number of pages (wizard steps) to show in this demo. 
    */ 

    @Override 
    public void onActivityCreated(@Nullable Bundle savedInstanceState) { 
     super.onActivityCreated(savedInstanceState); 
     Activity mActivity = getActivity(); 
     FragmentActivity mContext; 
     mContext=(FragmentActivity) mActivity; 

     ViewPager = new ViewPager(mContext); 
     ViewPager.setId(R.id.slide); 
     mContext.setContentView(ViewPager); 

     mPagerAdapter = new ScreenSlidePagerAdapter(mContext.getSupportFragmentManager()); 
     ViewPager.setAdapter(mPagerAdapter); 
     ViewPager.setCurrentItem(1); 

    } 



    /** 
    * A simple pager adapter that represents 5 ScreenSlidePageFragment objects, in 
    * sequence. 
    */ 
    private class ScreenSlidePagerAdapter extends FragmentStatePagerAdapter { 
     public ScreenSlidePagerAdapter(FragmentManager fm) { 
      super(fm); 
     } 

     @Override 
     public Fragment getItem(int position) { 
      return new ScreenSlidePageFragment(); 
     } 

     @Override 
     public int getCount() { 
      return NUM_PAGES; 
     } 
    } 


}

ScreenSlidePageFragment

public class ScreenSlidePageFragment extends Fragment { 
ViewGroup rootView = null; 
SharedPreferences sharedpreferences; 
public static final String MyPREFERENCES = "MyPrefs" ; 
@Override

         Bundle savedInstanceState) { 
     rootView = (ViewGroup) inflater.inflate(
      R.layout.fragment_screen_slide_page,container,false); 


    return rootView; 
} 
public void onActivityCreated(@Nullable Bundle savedInstanceState) { 
    super.onActivityCreated(savedInstanceState); 
    Activity mActivity = getActivity(); 
    Context mContext = getActivity(); 

    TextView slide_txt = (TextView) rootView.findViewById(R.id.slide); 

    SharedPreferences prefs = mContext.getSharedPreferences(MyPREFERENCES , MODE_PRIVATE); 
    int restoredText = prefs.getInt("nbr", 0); 

    slide_txt.setText(Integer.toString(restoredText)); 

    sharedpreferences = mContext.getSharedPreferences(MyPREFERENCES, MODE_PRIVATE); 
    SharedPreferences.Editor editor = sharedpreferences.edit(); 
    editor.putInt("nbr", 1+ restoredText); 
    editor.commit(); 
}

如何顯示在我的主要活動這個網頁瀏覽器？ 感謝您閱讀我

Answer 1

裏面你TestSlideFragment替換下面的代碼，你寫內部onActivityCreated

ViewPager = new ViewPager(mContext); 
    ViewPager.setId(R.id.slide); 
    mContext.setContentView(ViewPager); 

與

ViewPager = (ViewPager)getView().findViewById(R.id.page); 

，並嘗試再次運行應用程序。

Answer 2

爲什麼要在setcontentview方法中添加viewpager？這爲整個活動樹立了觀點。

找到像

vp = (ViewPager) view.findViewById(R.id.viewpager).
