i have nested recycle view and i want to remove one item (inner recycle view) from the outer recycle view but my code clear all adapters in the inner recycle view so how can i delete or clear only one list adapter from inner recycle view and is their is a better way to make nested recycle view .....?

I'm making my first app (calendar),
clicking the cardview item applies the same effect (changing Textview text color and Imageview background) to other items when scrolling the recycleview
in the main activity
RecyclerView daysRecyclerView;
DaysAdapter daysAdapter;
private RecyclerView.LayoutManager horizontalLayout;
ArrayList<DaysModel> daysModels;
#Override
protected void onCreate(Bundle savedInstanceState) {

daysRecyclerView.setHasFixedSize(true);
horizontalLayout = new LinearLayoutManager(this,RecyclerView.HORIZONTAL,false);

daysAdapter.setOnItemClickListener(new DaysAdapter.OnItemClickListener() {
#Override

});
}
public void dayClickHandler(int position, int change){
daysModels.get(position).changeDayHighlight(change);
daysAdapter.notifyItemChanged(position);

private ArrayList<DaysModel> getDaysList(){

for (i = 0;i <dayName.length;i++){
j =i+1;
models.add(new DaysModel(dayName[i], j, 0, false));

I'm using an interface for the onClickListener.

sorry for the long code text, I've just started and I am already struggling.
All you need is to set else part for you if condition in bind method of Adapter class.
So change your bind method to something like this:
#Override
public void onBindViewHolder(#NonNull DaysViewHolder holder, int position) {
DaysModel currentItem = daysModels.get(position);
holder.hDayName.setText(currentItem.getDayName());
holder.hDayNumber.setText(String.valueOf(currentItem.getDayNumber()));
if(currentItem.isDayHighlighted() == 1){
holder.currentDayHighlight.setBackgroundResource(R.drawable.tiny_background);
holder.hDayNumber.setTextColor(Color.BLACK);
}else{
holder.currentDayHighlight.setBackgroundResource(/*what ever you want for default situation*/);
holder.hDayNumber.setTextColor(/* for example Color.White*/);
}
}
I have a RecyclerView in which the user can drag and drop an item to a different position in the RecyclerView.
So far everything works fine.
My problem begins when the RecyclerView has more items than it can display. So when it recycle his content. When the user drag and drop an item to a different position and than scroll away from this part the position changes are not saved. The user just see the old positions for the items.
You can see this issue in the .gif below.
I already tried several things out like:
recyclerViewItem.getRecycledViewPool().setMaxRecycledViews(0,0);
recyclerViewItem.setItemViewCacheSize(30);
and
holder.setIsRecyclable(false);
inside of my onBindViewHolder.
But nothing seems to work for me.
Does anyone know a solution for this problem?
My Fragment class:
public class ShoppinglistFragment extends Fragment {
private ViewModel viewModel;
private ShoppinglistAdapter adapterShoppingItem = new ShoppinglistAdapter();
private RecyclerView recyclerViewItem;
private Boolean fragmentStarted = false;
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.shoppinglist_layout, container, false);
recyclerViewItem = view.findViewById(R.id.recyclerViewShoppinglist);
return view;
}
#Override
public void onActivityCreated(#Nullable Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
viewModel = ViewModelProviders.of(getActivity()).get(ViewModel.class);
fragmentStarted = true;
recyclerViewItem.setLayoutManager(new LinearLayoutManager(getContext()));
recyclerViewItem.setHasFixedSize(false);
recyclerViewItem.getRecycledViewPool().setMaxRecycledViews(0,0);
recyclerViewItem.setItemViewCacheSize(30);
recyclerViewItem.setAdapter(adapterShoppingItem);
ItemTouchHelper.Callback callback =
new ItemMoveCallback(adapterShoppingItem);
ItemTouchHelper touchHelper = new ItemTouchHelper(callback);
touchHelper.attachToRecyclerView(recyclerViewItem);
//fetch all Shoppinglist Items from local storage
viewModel.getAllShoppinglistItems().observe((LifecycleOwner) this, new Observer <List<Shoppinglist>>() {
#Override
public void onChanged(#Nullable List<Shoppinglist> items) {
if (fragmentStarted){
adapterShoppingItem.submitList(items);
fragmentStarted = false;
}
}
});
adapterShoppingItem.setOnPositionChanged(new ShoppinglistAdapter.onPositionChanged() {
#Override
public void onPositionChanged(Shoppinglist fromItem, Shoppinglist toItem, int fromPosition, int toPosition) {
int fromPositionServer = fromItem.getPosition();
int toPositionServer = toItem.getPosition();
fromItem.setPosition(toPositionServer);
toItem.setPosition(fromPositionServer);
//updating Shoppinglist Item locally
viewModel.updateItem(fromItem);
viewModel.updateItem(toItem);
}
});
}
}}
and my Adapter class:
public class ShoppinglistAdapter extends ListAdapter<Shoppinglist, ShoppinglistAdapter.NoteHolder> implements ItemMoveCallback.ItemTouchHelperContract {
public Integer ressourceType;
private onPositionChanged onPositionChanged;
private ArrayList<Shoppinglist> globalItemList = new ArrayList<Shoppinglist>();
public ShoppinglistAdapter() {
super(DIFF_CALLBACK);
Integer valueOf = Integer.valueOf(0);
this.ressourceType = valueOf;
}
private static final DiffUtil.ItemCallback<Shoppinglist> DIFF_CALLBACK = new DiffUtil.ItemCallback<Shoppinglist>() {
#Override
public boolean areItemsTheSame(Shoppinglist oldItem, Shoppinglist newItem) {
return oldItem.getSqlid() == newItem.getSqlid();
}
#Override
public boolean areContentsTheSame(Shoppinglist oldItem, Shoppinglist newItem) {
return oldItem.getTitle().equals(newItem.getTitle());
}
};
#NonNull
#Override
public NoteHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View itemView = LayoutInflater.from(parent.getContext())
.inflate(R.layout.shoppinglist_item, parent, false);
return new NoteHolder(itemView);
}
#Override
public void onBindViewHolder(#NonNull NoteHolder holder, int position) {
Shoppinglist currentItem = getItem(position);
holder.setIsRecyclable(false);
holder.tv.setText(currentItem.getTitle());
...
}
public Shoppinglist getNoteAt(int position) {
return getItem(position);
}
public class NoteHolder extends RecyclerView.ViewHolder {
private TextView tv;
public NoteHolder(View itemView) {
super(itemView);
tv= itemView.findViewById(R.id.tv);
globalItemList .add(currentNote);
}
}
public interface onPositionChanged {
void onPositionChanged(Shoppinglist fromItem, Shoppinglist toItem, int fromPosition, int toPosition);
}
public void setOnPositionChanged(ShoppinglistAdapter.onPositionChanged listener) {
this.onPositionChanged = listener;
}
#Override
public void onRowMoved(int fromPosition, int toPosition) {
//send switched Items to Fragment
onPositionChanged.onPositionChanged(globalItemList.get(fromPosition), globalItemList.get(toPosition), fromPosition, toPosition);
//switch Items inside of the global Item List
Collections.swap(globalItemList, fromPosition, toPosition);
notifyItemMoved(fromPosition, toPosition);
}
#Override
public void onRowSelected(NoteHolder myViewHolder) {}
#Override
public void onRowClear(NoteHolder myViewHolder) {}
#Override
public int getItemViewType(int position) {
return super.getItemViewType(position);
}
}
The problem is that you should swap items in ListAdapter.mDiffer which holds the current showing list. So, globalItemList in your code is unused. Replace onRowMoved of your adapter with the following one:
#Override
public void onRowMoved(int fromPosition, int toPosition) {
ArrayList<Shoppinglist> list = new ArrayList(getCurrentList());
Collections.swap(list, fromPosition, toPosition);
submitList(list);
}
There is a list of pictures made through RecyclerView. When you click on a picture while it is being transferred to the next activity, a ProgressBar should be displayed. When there is a return to the activity of the image selection, the ProgressBar also remains visible, although it must be hidden.
As I did below, the progress bar becomes invisible only in the first image, but in the rest it does not work. I can’t understand why
in my project there are such classes as:
interface
public interface ImageOnC {
void onClick(int position);
}
ImageViewHolder
public class ImageViewHolder extends RecyclerView.ViewHolder {
public ImageView imageView;
private ImageOnC imageOnC;
public ImageButton imageButton;
public ProgressBar progressBar;
public void setImageOnC(ImageOnC imageOnC) {
this.imageOnC = imageOnC;
}
public ImageViewHolder(#NonNull final View itemView) {
super(itemView);
imageView = itemView.findViewById(R.id.image_outline);
progressBar = itemView.findViewById(R.id.progr);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
imageOnC.onClick(getAdapterPosition());
progressBar.setVisibility(View.VISIBLE);
}
});
}
}
ImageAdabter
public class ImageAdabter extends RecyclerView.Adapter<ImageViewHolder> {
private Context mContext;
private List<Integer> listImages;
public ImageAdabter(Context mContext){
this.mContext = mContext;
this.listImages = getImages();
}
private List<Integer> getImages() {
List<Integer> results = new ArrayList<>();
results.add(R.drawable.outline1);
results.add(R.drawable.outline2);
results.add(R.drawable.outline3);
results.add(R.drawable.outline4);
results.add(R.drawable.outline5);
results.add(R.drawable.outline6);
results.add(R.drawable.outline7);
results.add(R.drawable.outline8);
results.add(R.drawable.outline9);
results.add(R.drawable.outline10);
return results;
}
#NonNull
#Override
public ImageViewHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View view = LayoutInflater.from(mContext).inflate(R.layout.item_images,parent,false);
return new ImageViewHolder(view);
}
#Override
public void onBindViewHolder(#NonNull final ImageViewHolder holder, final int position) {
holder.imageView.setImageResource( listImages.get(position));
holder.setImageOnC(new ImageOnC() {
#Override
public void onClick(int position) {
Common.PICTURE_SELECTED = listImages.get(position);
mContext.startActivity(new Intent(mContext, Colorful.class));
}
});
#Override
public void onBindViewHolder(#NonNull ImageViewHolder holder, int position, List<Object>payload){
//if so, then the progress bar only works for the first image in recyclerview
if(!payload.isEmpty()){
if(payload.get(position) instanceof Integer)
holder.progressBar.setVisibility(View.GONE);
}
else super.onBindViewHolder(holder, position, payload);
}
#Override
public int getItemCount() {
return listImages.size();
}
}
I add this to activity
private void initView() {
recyclerView = findViewById(R.id.recycle_view_images);
recyclerView.setHasFixedSize(true);
recyclerView.setLayoutManager(new LinearLayoutManager(this));
adabter = new ImageAdabter(this);
recyclerView.setAdapter(adabter);
}
#Override
public void onResume() {
super.onResume();
if (adabter != null) {
adabter.notifyItemChanged(position, position);
}
}
in xml file use Progress bar visibility gone
how can i filter Recycler View using SearchView
i try all the video tuturial but all of them get thier item Recycler View from a list
but i get my item from db and dont know how should i do this
this is my adapter Code
public class AthleteAdapter extends RecyclerView.Adapter<AthleteAdapter.AthleteHolder> {
private List<Athlete> athletes = new ArrayList<>();
private OnItemClickListener listener;
#NonNull
#Override
public AthleteHolder onCreateViewHolder(#NonNull ViewGroup parent, int viewType) {
View itemview = LayoutInflater.from(parent.getContext()).inflate(R.layout.athlete_item, parent, false);
return new AthleteHolder(itemview);
}
#Override
public void onBindViewHolder(#NonNull AthleteHolder holder, int position) {
Athlete currnetAthlete = athletes.get(position);
holder.textViewName.setText(currnetAthlete.getAthlete_name());
holder.textViewLastname.setText(currnetAthlete.getAthlete_lastname());
holder.textView_phonenumber.setText(currnetAthlete.getAthlete_phonenumber());
holder.textViewTime1.setText(String.valueOf(currnetAthlete.getSign_in_time()));
holder.textViewTime2.setText(String.valueOf(currnetAthlete.getCheck_tution_time()));
}
public void setAthletes(List<Athlete> athletes) {
this.athletes = athletes;
notifyDataSetChanged();
}
public Athlete getposition(int position) {
return athletes.get(position);
}
#Override
public int getItemCount() {
return athletes.size();
}
public void setOnItemClickListener(OnItemClickListener listener) {
this.listener = listener;
}
public interface OnItemClickListener {
void onItemClick(Athlete athlete);
}
class AthleteHolder extends RecyclerView.ViewHolder {
private TextView textViewName, textViewLastname, textView_phonenumber, textViewTime1, textViewTime2;
public AthleteHolder(#NonNull View itemView) {
super(itemView);
textViewName = itemView.findViewById(R.id.name_main);
textViewLastname = itemView.findViewById(R.id.lastname_main);
textView_phonenumber = itemView.findViewById(R.id.textView_number);
textViewTime1 = itemView.findViewById(R.id.time1);
textViewTime2 = itemView.findViewById(R.id.time2);
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int position = getAdapterPosition();
if (listener != null && position != RecyclerView.NO_POSITION) {
listener.onItemClick(athletes.get(position));
}
}
});
}
}
}
Step 1 : Get all data from db and give that list to Adapter
usersList = db.getAll();
adapter = new dataAdapter(getApplicationContext(), usersList);
adapter.setdatainterfacemethod(this);
Step 2 : get Text from Searchview
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String query) {
return false;
}
#Override
public boolean onQueryTextChange(String newText) {
filter(s.toString());
}
return false;
}
});
Step 3 : compare searchview text and list text if exits then give list to adapter
public void filter(String text) {
List<Users> name = new ArrayList<>();
for (Users u : usersList) {
if (u.getNAME().toLowerCase().contains(text.toLowerCase())) {
name.add(u);
}
}
adapter.filterlist(name);
}
Step 4 :- change list and notify adapter (in adapter class)
public void filterlist(List<Users> name) {
this.usersList = name;
notifyDataSetChanged();
}
--------------------- Adapter class -----------------
public class dataAdapter extends RecyclerView.Adapter<dataAdapter.viewholder> {
public List<Users> usersList;
Context context;
dataInterface dataInterface;
public dataAdapter(Context context, List<Users> usersList) {
this.usersList = usersList;
this.context = context;
}
public void setdatainterfacemethod(dataInterface dataInterface) {
this.dataInterface = dataInterface;
}
#NonNull
#Override
public viewholder onCreateViewHolder(#NonNull ViewGroup viewGroup, int i) {
View view = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.include_recycle_demo, viewGroup, false);
return new viewholder(view);
}
#Override
public void onBindViewHolder(#NonNull final viewholder viewholder, final int i) {
}
#Override
public int getItemCount() {
return usersList.size();
}
public void filterlist(List<Users> name) {
this.usersList = name;
notifyDataSetChanged();
}
public class viewholder extends RecyclerView.ViewHolder {
public viewholder(#NonNull View itemView) {
super(itemView);
}
}

I have a RecyclerView Fragment to which I added a Filter Search in an edit text. It works, but when I click in a Card of the Recycler, it goes to the wrong detail. My best guess is that it's getting the wrong position from the getAdapterPosition since let's say I have this list {a,b,c,d,e,f,g,h}. when I filter and get two itmes left like {d,g}. If I click d it redirects to a, if I click g it redirects to b.
This is my RecyclerView
public class RecyclerProfile extends Fragment implements
Adapter.AdapterListener, com.example.cake.profiling.Adapter.SearchListener
{
private RecyclerListener recyclerListener;
private List<Profile> profiles = (new DAOProfile()).getProfile();
private Adapter recyclerAdapter= new Adapter(profiles, this);
public RecyclerProfile() {
// Required empty public constructor
}
#Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
// Inflate the layout for this fragment
View view= inflater.inflate(R.layout.fragment_recycler_profile,
container, false);
RecyclerView recyclerView = view.findViewById(R.id.recyclerProfile);
EditText editText = view.findViewById(R.id.editText);
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count,
int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int
count) {
}
#Override
public void afterTextChanged(Editable s) {

}
});
recyclerView.setHasFixedSize(true);
RecyclerView.LayoutManager layoutManager = new
LinearLayoutManager(getContext(), LinearLayoutManager.VERTICAL, false);
recyclerView.setLayoutManager(layoutManager);
recyclerView.setAdapter(recyclerAdapter);
setHasOptionsMenu(true);
return view;
}
private void filter(String text){
ArrayList<Profile> filteredList = new ArrayList<>();
for (Profile profile: profiles){
if (profile.getName().toLowerCase().contains(text.toLowerCase())){
filteredList.add(profile);
}
}
recyclerAdapter.filterList(filteredList);
profiles = new ArrayList<>(filteredList);
}
#Override
public void listen(Profile profile, Integer position) {
recyclerListener.send(profile, position);
}
#Override
public void profileSelected(Profile profile) {

//INTERFACE
public interface RecyclerListener {
void send(Profile profile, Integer position);
}
//ON ATTACH
#Override
public void onAttach(Context context) {
super.onAttach(context);
this.recyclerListener = (RecyclerListener) context;

}
This is my Adapter
public class Adapter extends RecyclerView.Adapter<Adapter.ProfileViewHolder> {

private AdapterListener adapterListener;
//CONSTRUCTOR
public Adapter(List<Profile> profiles,AdapterListener adapterListener) {
this.profiles = profiles;

}
public void setter (Profile profile){

}
}
public interface AdapterListener {

getAdapterPosition()
this will return the position of the item of current data set. This is what I'd do

image.setOnClickListener(this);
}
public void setter (Profile profile){
if(profile != null) {
mProfile = profile;
name.setText(mProfile.getName());
image.setImageResource(mProfile.getImage());
}
}
}
#Override
public void onClick(View view) {
switch (view.getId()) {
case R.id.item_nameProfile:
case R.id.item_imageProfile:
for(int i = 0 ; i < profiles.size() ; i++) {
if(profiles.get(i).getName().equalsIgnoreCase(mProfile.getName()) {
adapterListener.receive(profiles.get(i), i);
break;
}
}
break;
}
}
public interface AdapterListener {
void receive(Profile profile, Integer position);
}
}
