when i clicked two item at the same time the app calls the interface method two times mListener.onListFragmentInteraction(holder.mItem);
It does
findNavController(requireActivity(), R.id.nav_host_support).navigate(R.id.action_brandsFragment_to_devicesFragment, bundle);

That's because on the first tap it switches to DevicesFragment, and the action doesn't exist in that graph when the second tap is handled.
You could add this check:
if (navController.currentDestination?.id != R.id.devicesFragment) {
navController.navigate(R.id.action_brandsFragment_to_devicesFragment)
}
or this one:
navController.currentDestination?.getAction(R.id.action_brandsFragment_to_devicesFragment)?.let {
navController.navigate(R.id.action_brandsFragment_to_devicesFragment)
}
and you can also make them extension functions if you want to

i need help for this filter or search with editText on fragment with recyclerView, when afterTextChanged running filter and toast show correct data, but in recyclerView not showing anything only blank list, i try create new add list but still nothing.
this is my fragment

no error on Logcat. i need help for this, sorry for bad english.

Look at this example
Adapter
public class ListAdapter extends RecyclerView.Adapter<ItemHolder> implements Filterable {
private Context iContext;
private List<DataNote > dataList = new ArrayList<>();
private List<DataNote > filterlist = new ArrayList<>();
public ListAdapter (List<DataNote > dataList, Context context) {
this.dataList = dataList;
this.filterlist = dataList;
iContext = context;
}
#Override
public Filter getFilter() {
Filter filter = new Filter() {
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
dataList= (List<DataNote >) results.values;
notifyDataSetChanged();
}
#Override
protected FilterResults performFiltering(CharSequence constraint) {
FilterResults results = new FilterResults();
List<DataNote> filteredList = new ArrayList<>();
String searchText = constraint.toString().toLowerCase();
String[] split = searchText.split(",");
ArrayList<String> searchGenres = new ArrayList<>(split.length);
for (String aSplit : split) {
// remove spaces
String trim = aSplit.trim();
// skip empty entries
if (trim.length() > 0)
searchGenres.add(trim);
}
for (DataNote dataNames : filterlist) {
// filter by title
if (dataNames.getCustomer().toLowerCase().trim().contains(searchText)) {
filteredList.add(dataNames);
}
}
results.count = filteredList.size();
results.values = filteredList;
return results;
}
};
return filter;
}
}
In Fragment :
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
mListadapter.getFilter().filter(s.toString());
}

1) In on bind, you are accessing object from dataList Object and your getItemCount() is also returning the size of dataList.
2) During filtering, you are performing filtering and storing the filtered data in filterlist and calling notifyDataSetChanged().
So here your dataList which has all the data, is shown always and not the filterlist which has the data which is filtered.
If you want to show the filtered data, you should use the filterlist with the recyclerview like,
public ListAdapter(ArrayList<DataNote> data)
{
this.dataList = data;
this.filterlist = new ArrayList(dataList);
}
#Override
public int getItemCount()
{
return filterlist.size();
}
#Override
public void onBindViewHolder(ListAdapter.ViewHolder holder, final int position)
{
holder.textViewBranch.setText(filterlist.get(position).getBranch());
holder.textViewAsset.setText(filterlist.get(position).getAssetcode());
holder.textViewCustomer.setText(filterlist.get(position).getCustomer());
holder.textViewLicense.setText(filterlist.get(position).getLisenceplate());
holder.btnReceive.setOnClickListener(new View.OnClickListener()
{
#Override
public void onClick(View v)
{
//Toast.makeText(getActivity(), "Item " + position + " is clicked.", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(getActivity(),
AssetReceiveActivity.class);
intent.putExtra("name",filterlist.get(position).getCustomer());
intent.putExtra("code",filterlist.get(position).getAssetcode());
intent.putExtra("plat",filterlist.get(position).getLisenceplate());
startActivity(intent);
}
});
}

How to get item position in viewholder when swipe with filtered text

I was able to get the value of the viewHolder.getAdapterPosition() but what Im after is when I search for items using Filter and tried to swipe the searched item it always gives me the position 0.
Example list:
0: Apple
1: Banana
2: Mango
3: Coconut
4: Peanut
I searched for peanut and it should be in the first item on the list but when I tried to swiped it always return 0 as apple.
Here is my code
#Override
public void onSwiped(RecyclerView.ViewHolder viewHolder, final int direction) {
Log.e("ITEM ID", String.valueOf(viewHolder.viewHolder.getAdapterPosition());
adapters.notifyDataSetChanged();
}
Please see Adapter Class:
public class ProductsAdapter extends RecyclerView.Adapter<ProductsAdapter.MyViewHolder>{
private Context context;
private List<ProductObject> productList;
private double total;
private List<ProductObject> filteredItems;
private ProductsInterface productsInterface;
public interface ProductsInterface {
void productsInt(ProductObject position);
}
public void setProductsInterface(ProductsInterface productsInterfaceListener){
productsInterface = productsInterfaceListener;
}
public class MyViewHolder extends RecyclerView.ViewHolder{
ImageView img_url;
TextView prod_desc, prod_uom, prod_price, prod_quantity;
public MyViewHolder(View itemView, final ProductsInterface listener) {
super(itemView);
prod_desc = (TextView) itemView.findViewById(R.id.card_product_name);
prod_uom = (TextView) itemView.findViewById(R.id.card_uom);
prod_price = (TextView) itemView.findViewById(R.id.card_price);
img_url = (ImageView) itemView.findViewById(R.id.card_imageView);
prod_quantity = (TextView) itemView.findViewById(R.id.prod_quantity);
//listener.productsInt(filteredItems.get(getAdapterPosition()));
itemView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
if (listener != null) {
//productsInterface.productsInt();
int position = getAdapterPosition();
Log.e("ADAPTER", String.valueOf(position));
if(position != RecyclerView.NO_POSITION){
listener.productsInt(filteredItems.get(getAdapterPosition()));
//ProductObject clickedItems = filteredItems.get(position);
}
}
}
});
}
}
public ProductsAdapter (Context context, List<ProductObject> listItems){
this.context = context;
this.productList = listItems;
this.filteredItems = listItems;
}
#Override
public ProductsAdapter.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.product_card_view, parent, false);
return new MyViewHolder(view, productsInterface);
}
#Override
public void onBindViewHolder(ProductsAdapter.MyViewHolder holder, int position) {
final ProductObject objectModel = filteredItems.get(holder.getAdapterPosition());
holder.prod_desc.setText(objectModel.getProd_desc());
holder.prod_uom.setText(objectModel.getProd_stockCode());
holder.prod_price.setText(String.valueOf(objectModel.getProd_price()));
holder.prod_quantity.setText(String.valueOf(objectModel.getProd_quantity()));
//prod id add here
/* Glide.with(context)
.load(objectModel.getProd_image())
.into(holder.img_url);*/
Glide.with(context)
.load(R.drawable.logo)
.into(holder.img_url);
}
#Override
public int getItemCount() {
return filteredItems.size();
}
public Filter getFilter() {
return new Filter() {
#Override
protected FilterResults performFiltering(CharSequence constraint) {
String charString = constraint.toString();
if (charString.isEmpty()) {
filteredItems = productList;
} else {
final ArrayList<ProductObject> mFilteredList = new ArrayList<>();
for (final ProductObject listFilter : productList) {
if (listFilter.getProd_desc().toLowerCase().contains(charString) ||
listFilter.getProd_stockCode().toLowerCase().contains(charString)
) {
mFilteredList.add(listFilter);
}
}
filteredItems = mFilteredList;
}
FilterResults filterResults = new FilterResults();
filterResults.values = filteredItems;
return filterResults;
}
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredItems = (ArrayList<ProductObject>) results.values;
notifyDataSetChanged();
}
};
}
}

Modify publishResults method to below
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
filteredItems.clear();
filteredItems.addAll((ArrayList<ProductObject>) results.values);
notifyDataSetChanged();
}

Getting wrong item selected from filtered list using recyclerview

I have a RecyclerView & EditText. I can select the item from RecyclerView & gets correct item unless it is not filtered.
On entering in EditText, RecyclerView list gets filtered & when I select any item from the list it shows me actual list item instead of selected one.

Please help me.

Please use this code snippet
private class ItemFilter extends Filter {
String filterString;
#Override

filterString = constraint.toString().toLowerCase();
FilterResults results = new FilterResults();
int count = filterArrayList.size();

for (int i = 0; i < count; i++) {
RegionDetail listItem = new RegionDetail();
listItem.setRegionID(filterArrayList.get(i).getRegionID());
listItem.setRegionName(filterArrayList.get(i).getRegionName());
filterList.add(listItem);
}
results.values =filterList;
results.count = filterList.size();
return results;
}
#Override
protected void publishResults(CharSequence constraint, FilterResults results) {
originalArrayList = (ArrayList<RegionDetail>) results.values;
notifyDataSetChanged();
}
}
i hope this code will filter your list correctly and you get right list item onClick.
