我们可以在视图分页器的一个父片段中嵌套两个子片段吗? [英] Can we nested two child fragment inside one parent fragment in view pager?

问题描述

我有一个视图分页器，在选项卡之一中，我有一个父片段，其中包含两个子片段.

I have a view pager,in one of tab I have parent fragment which contained two child fragment.

候选列表是具有框架容器的父片段，我在其中替换了一个子容器( candidatelistfragment )，但是当我替换了另一个子容器(候选事件开始)时，它说找不到视图.

Candidatelist is the parent fragment which had a frame container I replace one child(candidatelistfragment) inside that container but when I replace one more child(candidate event start) inside it it says view not found.

我用来替换父片段容器中的第一个孩子的代码是(这很好)

Code I am using to replace the first child inside the parent fragment container is (this works well)

Fragment childFragment = new CandidateListFragment();
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.replace(R.id.childContainer, childFragment,"listfragment").commit();

现在，当我必须在其中添加一个子容器时，childContainer是父容器的ID，它说未找到视图.

Here childContainer is the parent container's ID now when I have to add one more child inside it it says view not found.

 Fragment childFragment = new CandidateStartEvent();
 FragmentTransaction transaction =getChildFragmentManager().beginTransaction();
 transaction.replace(R.id.childContainer, childFragment).commit();

推荐答案

我已经解决了我使用getFragmentManager的第二个子片段上发布的问题

I have resolved the issued on the second child fragment I used getFragmentManager

CandidateStartEvent childFragment = new CandidateStartEvent();
FragmentTransaction transaction =getFragmentManager().beginTransaction();
transaction.replace(R.id.childContainer, childFragment).addToBackStack(null).commit();
