嵌套视图页程序嵌套片段错误

Question

我有一个Viewpager包含Recylerview，它有2个不同的持有者。其中之一是视图寻呼机。因此，我有嵌套的视图页和嵌套的片段。当我点击第二个选项卡并点击返回第一个选项卡时，它很好.但是当我点击第三个选项卡并点击返回第一个选项卡时。它给出以下错误：

java.lang.IllegalArgumentException: No view found for id 0x7f0f00ce (:id/viewPagerComments) for fragment CommentFragment 

维护活动

viewPager.setAdapter(new MainViewPagerAdapter(getSupportFragmentManager(),models.size()));
navigationTabBar.setModels(models);
navigationTabBar.setViewPager(viewPager, 0);

主视图寻呼机适配器

private int size;
public MainViewPagerAdapter(FragmentManager fm, int size) {
super(fm);
this.size = size;
}
@Override
public Fragment getItem(int position) {
switch (position) {
case 0:
return DashboardtFragment.newInstance(size, position);
default:
return TempFragment.newInstance(size, position);
}
}

DashboardtFragment

public static DashboardtFragment newInstance(int size, int index) {
Bundle args = new Bundle();
args.putInt(ARG_I,index);
args.putInt(ARG_S,size);
DashboardtFragment fragment = new DashboardtFragment();
fragment.setArguments(args);
return fragment;
} 
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState)
{
final View v = inflater.inflate(R.layout.dashboard_fragment, null);

return v;
}
@Override
public void showRecyleview(DashboardResponseModel model) {
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
DashboardRecyleViewAdapter adapter = new DashboardRecyleViewAdapter(getActivity(),getChildFragmentManager(),model);
recyclerView.setAdapter(adapter);
}

仪表板回收视图适配器

public static class ViewHolder1 extends RecyclerView.ViewHolder {
public ViewHolder1(View itemView) {
super(itemView);
viewPager = itemView.findViewById(R.id.viewPagerComments);
}
}
case 1 : 
return new ViewHolder1( layoutInflater.inflate(R.layout.dashboard_comments, parent, 
false));
case 1:
ViewHolder1 viewHolder1 = (ViewHolder1) holder;
viewPager.setAdapter(new CommentViewPagerAdapter(
childFragmentManager,
model.getCommentList().size(),
model.getCommentList()
));
break;

注释视图寻呼机适配器

public CommentViewPagerAdapter(FragmentManager fm, int size, 
List<CommentList> list) {
super(fm);
this.size = size;
this.list=list;
}
@Override
public Fragment getItem(int position) {
return CommentFragment.newInstance(size,position,list.get(position));
}

注释片段

public static CommentFragment newInstance(int size, int index, CommentList 
comment) {
Bundle args = new Bundle();
args.putString(ARG_C,new Gson().toJson(comment));
args.putInt(ARG_I,index);
args.putInt(ARG_S,size);
CommentFragment fragment = new CommentFragment();
fragment.setArguments(args);
return fragment;
}
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup 
container, @Nullable Bundle savedInstanceState)
{
final View v = inflater.inflate(R.layout.comment_content, null);
}

Answer 1

PagerAdapter mPagerAdapter;
@Override
protected void onDetachedFromWindow() {
super.onDetachedFromWindow();
super.setAdapter(null);
}
@Override
protected void onAttachedToWindow() {
super.onAttachedToWindow();
if (mPagerAdapter != null) {
super.setAdapter(mPagerAdapter);
}
}
@Override
public void setAdapter(PagerAdapter adapter) {
}
public void storeAdapter(PagerAdapter pagerAdapter) {
mPagerAdapter = pagerAdapter;
}

首先创建一个自定义视图页，然后添加上面的代码。使用 storeAdapter 而不是 setAdapter。
