當我點擊我的最後一個片段時出現錯誤

Question

我不能在我的應用程序中訪問最後一個片段（案例7）。我一直在調試它，我認爲這是一個邏輯錯誤，但我很難解決它。在

public void onSectionAttached(int number) { 
    String[] stringArray = getResources().getStringArray(R.array.section_titles); 
    if (number >= 1) { 
     mTitle = stringArray[number-1]; 
    } 
} 

所以這裏的部分是由在Android Studio中的默認導航抽屜導出我的代碼部分：

@Override 
public void onNavigationDrawerItemSelected(int position) { 
    // update the main content by replacing fragments 
    FragmentManager fragmentManager = getSupportFragmentManager(); 
    switch(position+1){ 
     case 1: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickReserveSeat.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 
     case 2: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickCancelSeat.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 
     case 3: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickMyTrips.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 
     case 4: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickUserAccount.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 
     case 5: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickLogout.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 
     case 6: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickHelp.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 
     case 7: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickAboutUs.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 
    } 
} 

public void onSectionAttached(int number) { 
    String[] stringArray = getResources().getStringArray(R.array.section_titles); 
    if (number >= 1) { 
     mTitle = stringArray[number-1]; 
    } 
} 

onClickAboutUs（最後一個片段類/方法）

public class onClickAboutUs extends Fragment { 
private static final String ARG_SECTION_NUMBER = "section_number"; 

public static onClickAboutUs newInstance(int sectionNumber) { 
    onClickAboutUs fragment = new onClickAboutUs(); 
    Bundle args = new Bundle(); 
    args.putInt(ARG_SECTION_NUMBER, sectionNumber); 
    fragment.setArguments(args); 
    return fragment; 
} 
public onClickAboutUs() { 

} 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
         Bundle savedInstanceState) { 
    View rootView = inflater.inflate(R.layout.fragment_about_us, container, 
      false); 

    return rootView; 
} 
@Override 
public void onAttach(Activity activity) { 
    super.onAttach(activity); 
    ((UserAccount) activity).onSectionAttached(getArguments().getInt(
      ARG_SECTION_NUMBER)); 
} 

}

你可以試試這個

 int pos = position+1; 

     switch(pos){ 
     case 1: 
      fragmentManager.beginTransaction() 
        .replace(R.id.container, onClickReserveSeat.newInstance(position + 1)).addToBackStack("tag") 
        .commit(); 
      break; 

... 
}
