ActionBar崩溃Android

Question

我遇到了一个操作栏的问题，我解释得很好。 所以，如果我在一个标签（选择说）如果有cliccassi意外崩溃的应用程序，我希望没有发生......但我不明白。 我会发布一些代码，我把它放在TAB配置的主要活动中。

private class TabListener<T extends Fragment> implements ActionBar.TabListener { 

    private Fragment mFragment; 

    private final Activity mActivity; 

    private final String mTag; 

    private final Class<T> mClass; 

    public TabListener(Activity activity, String tag, Class<T> clz) { 

     mActivity = activity; 

     mTag = tag; 

     mClass = clz; 

    } 
    public void onTabSelected(ActionBar.Tab tab, FragmentTransaction ft) { 

     // Check if the fragment is already initialized 

     if (mFragment == null) { 

      // If not, instantiate and add it to the activity 

      mFragment = Fragment.instantiate(mActivity, mClass.getName()); 

      ft.add(android.R.id.content, mFragment, mTag); 


     } else { 

      // If it exists, simply attach it in order to show it 
      ft.show(mFragment); 
      //ft.attach(mFragment); 

     } 

    } 
    public void onTabUnselected(ActionBar.Tab tab, FragmentTransaction ft) { 

     if (mFragment != null) { 

      // Detach the fragment, because another one is being attached 

      // ft.detach(mFragment); 
      ft.hide(mFragment); 
     } 

    } 
    public void onTabReselected(ActionBar.Tab tab, FragmentTransaction ft) { 

      ft.replace(tab.getPosition(),mFragment); 

     // User selected the already selected tab. Usually do nothing. 
    } 

}

它似乎并不认为你在FragmentTransaction进行交易commit。
检查this后的指导。
