从子片段本身动态替换子片段

Question

我正在使用一个自然包含片段的 Viewpager。在其中一个片段中，我有一个子片段（子片段），每个子片段都包含一个按钮，该按钮调用以下内容来替换子片段本身

FragmentManager manager = getChildFragmentManager();
FragmentTransaction transaction = manager.beginTransaction();
transaction.replace(R.id.containerProfileDetails, new ProfileDetailsAddressFragment());
transaction.commit();

只是为了让它更直观：

1) 是父片段

2) 是子片段。我需要通过按下子片段本身内部的按钮来替换子片段

?--------?
|   1    |
| ?-----?|
| | 2   ||
| |     ||
| ?-----?|
?--------?

注意：我知道可以使用这种方法替换片段，但是，似乎不可能对子片段执行此操作，因为它会引发以下错误。

java.lang.IllegalArgumentException: No view found for id 0x7f0f0104 (com.example.app:id/containerProfileDetails) for fragment ProfileDetailsAddressFragment

更新

父片段 XML：

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:gravity="center"
tools:context="com.example.app.fragments.ProfileDetailsFragment">

<TextView
    android:id="@+id/lbl_page"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:gravity="center"
    android:textSize="42sp"
    tools:text="2"
    android:visibility="gone"/>

<FrameLayout
    android:id="@+id/containerProfileDetails"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    ></FrameLayout>
</LinearLayout>

子片段 XML：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context="com.example.app.fragments.ProfileDetailsUserFragment">

<TextView
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:text="Fragment Profile User Details" />

<Button
    android:id="@+id/btnProfileDetailsUserNext"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="bottom|center"/>

</FrameLayout>

父片段 Java：

 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_profile_details, container, false);
    lblPage = (TextView) view.findViewById(R.id.lbl_page);

    FragmentManager manager = getChildFragmentManager();
    FragmentTransaction transaction = manager.beginTransaction();
    transaction.add(R.id.containerProfileDetails, new ProfileDetailsUserFragment());
    transaction.commit();
    return view;
}

子片段Java：

    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v = inflater.inflate(R.layout.fragment_profile_details_user, container, false);

    Button _btnProfileDetailsUserNext = (Button) v.findViewById(R.id.btnProfileDetailsUserNext);
    _btnProfileDetailsUserNext.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            FragmentManager manager = getChildFragmentManager();
            FragmentTransaction transaction = manager.beginTransaction();
            transaction.replace(R.id.containerProfileDetails, new ProfileDetailsAddressFragment());
            transaction.commit();
        }
    });
    return v;
}

将您的父片段和子片段代码替换为以下内容

Parent_Fragment.Java

 public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.fragment_profile_details, container, false);
    lblPage = (TextView) view.findViewById(R.id.lbl_page);

    FragmentManager manager = getChildFragmentManager();
    FragmentTransaction transaction = manager.beginTransaction();
    transaction.add(R.id.containerProfileDetails, new ProfileDetailsUserFragment());
    transaction.commit();
    return view;
}

Child_Fragment.Java

 public View onCreateView(LayoutInflater inflater, ViewGroup container,
                         Bundle savedInstanceState) {
    // Inflate the layout for this fragment
    View v = inflater.inflate(R.layout.fragment_profile_details_user, container, false);

    Button _btnProfileDetailsUserNext = (Button) v.findViewById(R.id.btnProfileDetailsUserNext);
    _btnProfileDetailsUserNext.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            FragmentManager manager = getFragmentManager();
            FragmentTransaction transaction = manager.beginTransaction();
            transaction.replace(R.id.containerProfileDetails, new ProfileDetailsAddressFragment());
            transaction.commit();
        }
    });
    return v;
}

我还没有测试代码，它可能会产生一些编译错误，但实现方法是正确的。
