I have some fragments within a RecyclerView which is added to the MainActivity body container. I have a fragment with toolbar and RecyclerView which is added to the MainActivity head container. I want to do a search on all elements of all RecyclerView and make setVisibility(View.GONE) for body container and setVisibility(View.VISIBLE) for head RecyclerView. I don’t understand how to make the search.

you can add getFilter() method on your Adapter class and onCreateOptionsMenu on your Fragment. Follow the following codes;
@Override
public void onCreateOptionsMenu(@NonNull Menu menu, @NonNull MenuInflater inflater) {
super.onCreateOptionsMenu(menu, inflater);
inflater.inflate(R.menu.seach_menu, menu);
MenuItem menuItem = menu.findItem(R.id.action_search);
androidx.appcompat.widget.SearchView searchView = (androidx.appcompat.widget.SearchView) menuItem.getActionView();
searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
@Override
public boolean onQueryTextSubmit(String query) {
return false;
}
@Override
public boolean onQueryTextChange(String newText) {
customAdapter_halal.getFilter().filter(newText);
return false;
}
});
}
and
public class CustomAdapter extends RecyclerView.Adapter<CustomAdapter.ViewHolder> implements Filterable {
private Context context;
LayoutInflater layoutInflater;
List<Model> modeller;
List<Model> filteredModel;
public CustomAdapter(Context context, List<Model> models) {
this.context = context;
this.modeller = models;
this.filteredModel = models; // bu sekilde ekliyoruz
}
@NonNull
@Override
public CustomAdapter.ViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
layoutInflater = LayoutInflater.from(context);
View v = layoutInflater.inflate(R.layout.row_list, parent, false);
return new ViewHolder(v);
}
@Override
public void onBindViewHolder(@NonNull CustomAdapter.ViewHolder holder, int position) {
holder.name.setText(filteredModel.get(position).getName());
holder.packageName.setText(filteredModel.get(position).getPackageName());
holder.developer.setText(filteredModel.get(position).getDeveloperName());
holder.price.setText(filteredModel.get(position).getPrice() + " " + "€");
holder.rating.setText(String.valueOf(filteredModel.get(position).getRatingValue()));
Picasso.get().load(filteredModel.get(position).getIconUrl()).into(holder.image_icon);
holder.linearLayout.setTag(holder);
holder.linearLayout.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
ViewHolder viewHolder = (ViewHolder) v.getTag();
int position = holder.getAdapterPosition();
Intent intent = new Intent();
intent.setAction(Intent.ACTION_VIEW);
intent.addCategory(Intent.CATEGORY_BROWSABLE);
String pName = filteredModel.get(position).getPackageName();
String sabit = "https://play.google.com/store/apps/details?id=";
String uzanti = sabit + pName;
intent.setData(Uri.parse(uzanti));
context.startActivity(intent);
}
});
}
@Override
public int getItemCount() {
return filteredModel.size();
}
@Override
public Filter getFilter() {
return new Filter() {
@Override
protected FilterResults performFiltering(CharSequence charSequence) {
String searchString = charSequence.toString();
if (searchString.isEmpty()) {
filteredModel = modeller;
} else {
ArrayList<Model> tempFilteredList = new ArrayList<>();
for (Model model : modeller) {
// search for user name
if (model.getName().toLowerCase().contains(searchString)) {
tempFilteredList.add(model);
}
}
filteredModel = tempFilteredList;
}
FilterResults filterResults = new FilterResults();
filterResults.values = filteredModel;
return filterResults;
}
@Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
filteredModel = (ArrayList<Model>) filterResults.values;
notifyDataSetChanged();
}
};
}
public class ViewHolder extends RecyclerView.ViewHolder {
TextView name, packageName, developer, rating, price;
LinearLayout linearLayout;
ImageView image_icon;
public ViewHolder(@NonNull View itemView) {
super(itemView);
name = itemView.findViewById(R.id.text_name);
packageName = itemView.findViewById(R.id.text_packagename);
developer = itemView.findViewById(R.id.text_developer);
rating = itemView.findViewById(R.id.text_rating);
price = itemView.findViewById(R.id.text_price);
image_icon = itemView.findViewById(R.id.image_icon);
linearLayout = itemView.findViewById(R.id.linear_layout);
}
}
}
and the most important point is don't forget adding setHasOptionsMenu(true); on your oncreateview() method.
