Update the RecyclerView adapter items in fragment

Update the RecyclerView adapter items in fragment - android

I put a Recycler View into my fragment activity , which contains a number of Card View items
But when I click on the Refresh button, those items are created just for the first time
And when the Fragment is loaded for the next time, the items are not fetch again, and this is done only for the first time.
public class posts_fragment extends Fragment {

PostDataAdapter adapter=new PostDataAdapter(PostDataList);

public View onCreateView(LayoutInflater inflater, #Nullable ViewGroup container, Bundle savedInstanceState) {
View view=inflater.inflate(R.layout.posts_menu,container,false);
recyclerView =view.findViewById(R.id.PostRecycleView);
filldate();
recyclerView.setAdapter(adapter);
recyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));
return view;
}
public void filldate() {
//Start Get And Set Json Into Card View

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

JSONObject object = array.getJSONObject(i);
Review obj = new Review(object.getInt("studentId"),object.getInt("courseId"),object.getString("Review"),object.getLong("rating"));
results.add(i,obj);
}
catch (Exception e){
e.printStackTrace();
}
}
return results;
}
try to change your getDataSet function with above code and check with debug point if you get any problem in some line. feel free to ask further will help you
EDIT:
You need to change your Pojo class of Review also. Because in JSON response you are not getting userId and reviewId. Hope you understand
