我有一个嵌套列表。其中父级是ExpandableListView，而Child是具有ListFragemnt的viewpager。
最初，在viewpager Listfragment中使用Listitems填充子视图。一旦我崩溃并重新选择或选择另一个groupItem，它就会抛出错误IllegalArgumentException：找不到片段的id 0x7f0d0137（... / vp_incve_list）的视图。
我试过调试，Fragments都被替换得很好，fragmentmanger也返回片段getByTag。
无法找到问题所在，以下是我的代码中的代码段。 如果有人能帮我解决出错的地方。
@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;
}
