Androidフラグメントのライフサイクル：onResumeが2回呼び出されました

Question

ユーザーが別のアクティビティに切り替えてから現在のフラグメントにスクロールしてからスクロールを復元しようとしています。ここ は何が起こるかです：

ユーザーが何もしませんが、あなたが、最初のフラグメントのonResumeはonPauseを行くストレートの後に見ることができるように。

質問：私のコードに何が間違っていますか？

public class DisplayNoteActivity extends Activity { 

private Context mContext; 
//static final int SUBACT_EDITNOTE=100; 
private long m_NoteID; 
private String m_sTextNoAbbrev; 


@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    try 
    { 
     Log.v("DEBUG", "DisplayNoteActivity.onCreate()"); 
     setContentView(R.layout.activity_display_note); 

     Bundle extras = getIntent().getExtras(); 
     m_NoteID = extras.getLong("DisplayNote_NOTEID"); 
     m_sTextNoAbbrev = extras.getString("DisplayNote_TextNoAbbrev"); 

     if (savedInstanceState != null) 
      RefreshFragment(); 
    } 
    catch(Exception e){ 
     Toast.makeText(this, e.getMessage() , Toast.LENGTH_LONG).show(); 
     e.printStackTrace(); 
    } 

} 


public void onSaveInstanceState(Bundle savedInstanceState) 
{ 
    Log.v("DEBUG", "DisplayNoteActivity.onSaveInstanceState()"); 
    super.onSaveInstanceState(savedInstanceState); 
    savedInstanceState.putLong("DisplayNote_NOTEID", m_NoteID); 
    savedInstanceState.putString("DisplayNote_TextNoAbbrev", m_sTextNoAbbrev); 
} 

public void onRestoreInstanceState(Bundle savedInstanceState) { 
    super.onRestoreInstanceState(savedInstanceState); 
    // Restore UI state from the savedInstanceState. 
    // This bundle has also been passed to onCreate. 
    Log.v("DEBUG", "DisplayNoteActivity.onRestoreInstanceState()"); 
    m_NoteID = savedInstanceState.getLong("DisplayNote_NOTEID"); 
    m_sTextNoAbbrev= savedInstanceState.getString("DisplayNote_TextNoAbbrev"); 
} 

@Override 
public void onResume() { 
    Log.v("DEBUG", "DisplayNoteActivity.onResume()"); 
    super.onResume(); 

    RefreshFragment(); 
} 


private void RefreshFragment() 
{ 

    Bundle bundle = new Bundle(); 
    bundle.putLong("DisplayNote_NOTEID", m_NoteID); 
    bundle.putString("DisplayNote_TextNoAbbrev", m_sTextNoAbbrev); 

    android.app.FragmentManager fm=getFragmentManager(); 
    android.app.FragmentTransaction ft = fm.beginTransaction(); 

    DisplayNoteFragment dnf = new DisplayNoteFragment(); 
    dnf.setArguments(bundle); 
    ft.replace(R.id.container, dnf); 

    ft.commit(); 
}}

断片のonResumeが二度呼ば取得なぜその倍だ

は、ここに私のコードです。アクティビティのonCreate（）からのみRefreshFragment（）を呼び出す必要があり、アクティビティのonResume（）からコールする必要はありません。
