如何在SwipeView活动中向片段发送/接收额外信息

Question

我想在Android中使用带有选项卡的Swipe View，并且需要将某些变量传递给选项卡片段以显示自定义内容，我的问题是我总是将绑定为0，所以我认为我在从分段容器页面发送额外信息时出错。这是包含选项卡的片段和主片段页面的代码。

public Fragment getItem(int position) { 
     // getItem is called to instantiate the fragment for the given page. 
     // Return a PlaceholderFragment (defined as a static inner class 
     // below). 

     prof = getIntent().getIntExtra("prof", 0); 
     id = getIntent().getIntExtra("id", 0); 
     bund = new Bundle(); 
     bund.putInt("prof", prof); 
     bund.putInt("id", id); 

     switch (position) { 
      case 0: 
       // Text fragment activity 
       FragmentOne fragment = new FragmentOne(); 
       fragment.setArguments(bund); 
       return fragment; 
      case 1: 
       // Gallery fragment activity 
       FragmentTwo fragment2 = new FragmentTwo(); 
       fragment2.setArguments(bund); 
       return fragment2; 
      case 2: 
       //Audio fragment 
       FragmentThree fragment3 = new FragmentThree(); 
       fragment3.setArguments(bund); 
       return fragment3; 
      } 

      return null; 
    } 

而片段代码放置在onCreateView方法

Bundle bundle = getArguments(); 
    if (bundle!=null){ 
    prof = bundle.getInt("prof"); 
    id = bundle.getInt("id"); 
    } 

我可以读取进入片段容器，但到我无法读取它们的片段中的论点，我怎么忘了？

您可以用SharedPreference代替Bundle这里尝试：

实例化SharedPreference在FragmentStatePagerAdapter：

SharedPreference mPref = mContext.getSharedPreferences("myPreference", 
      Context.MODE_PRIVATE); 

商店prof和id到mPref：

public Fragment getItem(int position) { 
    // getItem is called to instantiate the fragment for the given page. 
    // Return a PlaceholderFragment (defined as a static inner class 
    // below). 

    prof = getIntent().getIntExtra("prof", 0); 
    id = getIntent().getIntExtra("id", 0); 
    // store value in mPref 
    mPref.putInt("prof", prof); 
    mPref.putInt("id", id); 

    // commit changes 
    mPref.commit(); 

switch (position) { 
    case 0: 
     // Text fragment activity 
     FragmentOne fragment = new FragmentOne(); 

     return fragment; 
    case 1: 
     // Gallery fragment activity 
     FragmentTwo fragment2 = new FragmentTwo(); 

     return fragment2; 
    case 2: 
     //Audio fragment 
     FragmentThree fragment3 = new FragmentThree(); 

     return fragment3; 
    } 

    return null; 
} 

Retrive值内的onCreateView()任何片段：

SharedPreference mPrefFrag = getActivity().getSharedPreferences("myPreference", 
     Context.MODE_PRIVATE);  
int prof = mPrefFrag.getInt("prof",0); 
int id = mPrefFrag.getInt("id",0);
