Android：片段：onCreateView不叫

我有一個沙盒項目，一切正常，但不是在真正的項目。我想我錯過了什麼......Android：片段：onCreateView不叫

在主要活動中我有（我已經簡化，就像我能項目）：

@Override 
    public void onCreate(Bundle bundle) { 
    super.onCreate(bundle); 
    setContentView(createUI()); 
    } 

    public View createUI() { 
    LinearLayout rootLayout = new LinearLayout(this); 
    rootLayout.setOrientation(LinearLayout.HORIZONTAL); 
    rootLayout.setLayoutParams(new LinearLayout.LayoutParams(ViewGroup.LayoutParams.FILL_PARENT, ViewGroup.LayoutParams.FILL_PARENT)); 
    LinearLayout leftLayout = new LinearLayout(this); 
    leftLayout.setLayoutParams(new LinearLayout.LayoutParams(300, ViewGroup.LayoutParams.FILL_PARENT)); 
    leftLayout.setId(11111); 

    android.widget.TextView textView = new android.widget.TextView(this); 
    textView.setText("112233"); 

    rootLayout.addView(textView); 
    rootLayout.addView(leftLayout); 
    { 
     FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
     ModelEditorFragment simpleFragment = new SimpleFragment(); 
     transaction.add(11111, simpleFragment); 
    } 
    return rootLayout; 
    }

而且在SimpleFragment.java：

@Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle bundle) { 
    TextView textView = new TextView(getActivity()); 
    textView.setText("SimpleFragmentText"); 
    return textView;

但是，當我開始我只看到112233沒有SimpleFragmentText。在調試時我注意到onCreateView方法永遠不會被調用......爲什麼？它看起來像相同的代碼在獨立的應用程序很好...可能是有我不知道的其他東西？

遺憾。我剛剛在實際項目中忘記了transaction.commit（）... – leshka

我忘記器transaction.commit：

{ 
     FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
     ModelEditorFragment simpleFragment = new SimpleFragment(); 
     transaction.add(11111, simpleFragment); 
     transaction.commit(); 
    }

rootLayout.addView(textView); 
{ 
    rootLayout.addView(leftLayout); 
    { 
     FragmentTransaction transaction = getFragmentManager().beginTransaction(); 
     ModelEditorFragment simpleFragment = new SimpleFragment(); 
     transaction.add(11111, simpleFragment); 
    } 
} 
    return rootLayout;

嘗試，我想你的rootLayout就是缺少TextView的附加部分
