I want to have bottom sheet, which display two fragments inside viewpager. I used two Fragments with FragmentPagerAdapter and BottomSheetDialogFragment to build dialog.
My problem was in the viewPager, the second fragment recyclerview dont scroll.

Recyclerview adapter
public class LigneListAdapter extends RecyclerView.Adapter<LigneListAdapter.ListViewHolder> {
Context context;
List<Ligne> lignes = new ArrayList<>();
LayoutInflater inflater;
ListListener listener;
public LigneListAdapter(Context context, List<Ligne> list) {
this.context = context;
this.lignes = list;
//this.listener= (ListListener) context;
inflater = LayoutInflater.from(context);
}
@Override
public ListViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View convertView = inflater.inflate(R.layout.ligne_list_row, parent, false);
ListViewHolder viewHolder = new ListViewHolder(convertView);
return viewHolder;
}
@Override
public void onBindViewHolder(ListViewHolder holder, int position) {
holder.ligne_icon.setTag(position);
holder.ligne_name.setText(lignes.get(position).getNomLigne());
holder.ligne_name.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
// listener.nameToChnge(lignes.get((Integer) v.getTag()).getId());
}
});
}
@Override
public int getItemCount() {
return lignes.size();
}
class ListViewHolder extends RecyclerView.ViewHolder {
TextView ligne_name;
ImageView ligne_icon;
public ListViewHolder(View itemView) {
super(itemView);
ligne_name = (TextView) itemView.findViewById(R.id.ligne_name);
ligne_icon= (ImageView) itemView.findViewById(R.id.ligne_icon);
}
}
}
My first fragment code (same like second)
public class LigneFragment extends Fragment implements ListListener {
private RecyclerView recyclerView;
private LigneDAO ligneDAO ;
private LigneListAdapter adapter;
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
// super.onCreateView(inflater,container,savedInstanceState);
View v = inflater.inflate(R.layout.ligne_fragment_list_view, null);
ligneDAO = new LigneDAO(getContext());
ligneDAO.open();
recyclerView = (RecyclerView) v.findViewById(R.id.recycler_list_view);
adapter = new LigneListAdapter(getContext(), ligneDAO.getAllLignes());
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(getContext()));
ligneDAO.close();
return v;
}
@Override
public void nameToChnge(String name) {
}
@Override
public void getStationSelected(Station station) {
}
}
FragmentPagerAdapter
public class PagerAdapter extends FragmentPagerAdapter {
public PagerAdapter(FragmentManager fm) {
super(fm);
}
@Override
public Fragment getItem(int position) {
Fragment frag=null;
switch (position){
case 0:
frag=new LigneFragment();
break;
case 1:
frag=new StationFragment();
break;
}
return frag;
}
@Override
public int getCount() {
return 2;
}
@Override
public CharSequence getPageTitle(int position) {
String title=" ";
switch (position){
case 0:
title="Lignes";
break;
case 1:
title="Stations";
break;
}
return title;
}
}
BottomSheetDialogFragment
public class AlsaBottomDialogFragment extends BottomSheetDialogFragment {
private static final String TAB_POSITION = "tab_position";
private PagerAdapter adapter;
private ViewPager viewPager;
private TabLayout tabLayout;
private LinearLayoutManager mLinearLayoutManager;
private AlsaRecyclerAdapter mAdapter;
public AlsaBottomDialogFragment(){
}
private BottomSheetBehavior.BottomSheetCallback mBottomSheetBehaviorCallback = new BottomSheetBehavior.BottomSheetCallback() {
@Override
public void onStateChanged(@NonNull View bottomSheet, int newState) {
if (newState == BottomSheetBehavior.STATE_HIDDEN) {
dismiss();
}
}
@Override
public void onSlide(@NonNull View bottomSheet, float slideOffset) {
}
};
@Nullable
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View root = inflater.inflate(R.layout.bottom_sheet, container);
tabLayout = (TabLayout) root.findViewById(R.id.tablayout);
viewPager = (ViewPager) root.findViewById(R.id.viewpager);
adapter = new PagerAdapter(getChildFragmentManager());
viewPager.setAdapter(adapter);
tabLayout.post(new Runnable() {
@Override
public void run() {
tabLayout.setupWithViewPager(viewPager);
}
});
return root;
}
@Override
public void onViewCreated(View contentView, @Nullable Bundle savedInstanceState) {
super.onViewCreated(contentView, savedInstanceState);
}
@Override
public void setupDialog(Dialog dialog, int style) {
super.setupDialog(dialog, style);
View contentView = View.inflate(getContext(), R.layout.bottom_sheet, null);
dialog.setContentView(contentView);
CoordinatorLayout.LayoutParams layoutParams =
(CoordinatorLayout.LayoutParams) ((View) contentView.getParent()).getLayoutParams();
CoordinatorLayout.Behavior behavior = layoutParams.getBehavior();
if (behavior != null && behavior instanceof BottomSheetBehavior) {
((BottomSheetBehavior) behavior).setBottomSheetCallback(mBottomSheetBehaviorCallback);
}
}
}
I dont know where are the prolem, help please
