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();
只是为了让它更具视觉效果:
1)是父片段
2)是子片段。 我需要通过按下子片段本身内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,似乎无法对子片段执行此操作,因为它会引发跟踪错误。

用下面的
替换您的父片段和子片段代码
<强> Parent_Fragment.Java 强>
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;
}
<强> Child_Fragment.Java 强>
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;
}
我没有测试过代码,可能会产生一些编译错误,但实现的方法是正确的。

这不起作用,因为在子片段中,片段事务正在查找标识为R.id.containerProfileDetails
的容器。此容器不在Child Fragment中,但它位于Parent Fragment中。
您需要做的是创建从Child Fragment到Parent Fragment的回调。在子片段的Onclick中,调用Parent Fragment的回调,然后在Parent Fragment中,将Child Fragment替换为所需的片段。
