Java ActionBar崩溃Android

我对动作栏有问题，我解释得很好。 所以，如果我在一个选项卡上（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。 我将在主活动中发布一些代码，用于配置选项卡

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.
    }

}

您似乎没有在

FragmentTransaction

中执行事务
