带有 Viewpager 的 IllegalArgumentException ExpandableList

Question

我有一个嵌套列表。其中父项是 ExpandableListView，子项是带有 ListFragemnt 的 viewpager。

最初，子视图由 viewpager Listfragment 中的 Listitems 填充。一旦我折叠并重新选择或 Select 另一个 groupItem，它就会抛出一个错误 IllegalArgumentException: No view found for id 0x7f0d0137 (.../vp_incve_list) for fragment.

我试过调试，Fragments 都被替换好了，fragmentmanger 也returns fragment getByTag。

找不到问题出在哪里，下面是我的代码片段。如果有人能帮我指出哪里出了问题。

@Override
public View getChildView(int groupPosition, final int childPosition, boolean isLastChild,
                         View convertView, ViewGroup parent) {

    if (convertView == null) {
        convertView = inflater.inflate(R.layout.item_incen_row, null);
        childHolder = new ChildHolder();

        childHolder.vpIncList = (ViewPager) convertView.findViewById(R.id.vp_incve_list);

        convertView.setTag(childHolder);
    }
    else {
        childHolder = (ChildHolder) convertView.getTag();
    }

    child = groupItems.get(groupPosition).getIncevList();


    mSectionsPagerAdapter = new SectionsPagerAdapter(context, fragmentManager, child);
    childHolder.vpIncList.setAdapter(mSectionsPagerAdapter);

    return convertView;
}

SectionPagerAdapter

@Override
public Fragment getItem(int position) {

    Fragment fragment = new CustomListFragment();
    Bundle args = new Bundle();
    args.putInt(CustomListFragment.POSITION, position );
    fragment.setArguments(args);
    return fragment;
}

其中IncentiveListAdapter是expandablelist适配器

Answer 1

正如您自己指出的那样，您使用了没有片段的 viewpager。

所以，看看下面这个 Whosebug 问题的答案。
