Your code very confusing so i just write my solution.
public class SomeAdapter extends RecyclerView.Adapter<SomeAdapter.SomeViewHolder> implements Filterable{
...
#Override
public Filter getFilter() {
Filter filter = new Filter() {
#Override
protected FilterResults performFiltering(CharSequence charSequence) {
mMainList = mYourJSONResponseList;
FilterResults results = new FilterResults();
ArrayList<YourModel> mFilter_list = new ArrayList<>();
//Place your logic
for (YourModel model : mMainList) {
if(model.getName().
toLowerCase().contains(text.toLowerCase())) {
mFilter_list.add(model);
}
}
results.count = mFilter_list.size();
results.values = mFilter_list;
return results;
}
#Override
protected void publishResults(CharSequence charSequence, FilterResults filterResults) {
mMainList = (ArrayList<YourModel>) filterResults.values;
notifyDataSetChanged();
}
};
return filter;
}
And add this into your text listener
#Override
public void afterTextChanged(Editable s) {
//Add this
adapter.getFilter().filter(s.toString())
}
NOTE!! You will show mMainList only this list in your RecyclerView, And check nullpointerexceptions

Log.e("Fare : ",busData.getFare());
}
After sorting completed call Adapter to list the data:
adapter = new BusDataAdapter(this, bdata);
fromto.setAdapter(adapter);
adapter.setJourneyBus(date_bus);
filter_list.addAll(bdata);
adapter = new BusDataAdapter(this, filter_list);
fromto.setAdapter(adapter);

You can use Collections.sort method for this..
Do like this...
Collections.sort(filterlist, new Comparator<bData>() {
#Override
public int compare(bData lhs, bData rhs) {
return (lhs.getFair() > rhs.getFair()) ? -1 : (lhs.getFair() > rhs.getFair()) ? 1 : 0;
}
});

You need to use comparator api in android.
Comparator<BusData> comparator=new Comparator<BusData>() {
#Override
public int compare(final BusData lhs, final BusData rhs) {
return lhs.getFare().equals(rhs.getFare());
}
};
Collections.sort(busDataList,comparator);
then your list will be sorted.

You need to give already sorted collection of buses to your adapter. Adapter shouldn't be responsible for sorting and ListView as well.
Try this:
Collections.sort(bdata, new Comparator<BusData>() {
#Override
public int compare(BusData lhs, BusData rhs) {
return lhs.getFare() > rhs.getFare();
}
});

You can use the Comparator and sort the list
class FareComparator implements Comparator{
public int Compare(Object o1,Object o2){
BusData s1=(BusData)o1;
BusData s2=(BusData)o2;
if(s1.fare==s2.fare)
return 0;
else if(s1.fare>s2.fare)
return -1;
else
return 1;
}
}
and use
Collections.sort(bdata,new FareComparator());
before the
adapter = new BusDataAdapter(this, bdata);

Un-filtering the result is not working in Recyclerview

I have a recyclerview with some data and I have a searchview, and filter is working just fine. But un-filtering not working. I can't get the whole data in the recyclerview after un-filter. No data is showing. I have to re-open the activity to get data. I tried to used two data sets. But i have no idea where to use them.

Just Modify your function and Add check for null or "" .
it will work fine
private ArrayList<SuggestGetSet> filter(ArrayList<SuggestGetSet> models, String query) {
if(TextUtils.isEmpty(query)){
return models;
}
query = query.toLowerCase();
final ArrayList<SuggestGetSet> filteredModelList = new ArrayList<>();
for (SuggestGetSet model : models) {
final String text = model.getName().toLowerCase();
if (text.contains(query)) {
filteredModelList.add(model);
}
}
return filteredModelList;
}
