如何在视图寻呼机内部的嵌套片段中刷新子片段？

您好，我想刷新我当前的片段，我在项目结构中有这个概念和逻辑，http://tausiq.wordpress.com/2014/06/06/android-multiple-fragments-stack-in-each-viewpager-tab/

当我从孩子回到父母时，我想刷新我的混合父片段，主要问题是当我要回来的时候，this总是空的，意味着getActivity没有意思，

我试过这段代码，但它不能正常工作

SearchResultFragment是我最受欢迎的父片段，

refreshCode

    SearchResultFragment addSearchResultFragment = new SearchResultFragment();

    getChildFragmentManager().beginTransaction().detach(SearchResultFragment.this).replace(R.id.frmlay_search_result, addSearchResultFragment).attach(addSearchResultFragment)
    .addToBackStack(null).commit();

这是我的即将到来的父片段xml。

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/frmlay_search_result"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".fragments.SearchResultFragment" >

    <RelativeLayout
        android:id="@+id/rel_main_cover"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@drawable/backgound" >

                    android:id="@+id/btn_sr_comaprechk"
                    android:layout_width="wrap_content"
                    android:layout_height="wrap_content"
                    android:enabled="false"
                    android:paddingLeft="10dp"
                    android:paddingRight="10dp"
                    android:text="@string/btn_sr_comaprechk" />

    </RelativeLayout>

</FrameLayout>
