如何在具有两个不同视图持有者的异构recyclerview中实现文件管理器（搜索）？

Question

Here is the code I am not able to implement search in heterogeneous recyclerview with two different viewholders. Can anyone suggest me something. Moreover my views of recyclerview are textViews and cardViews. CardView is having data written on it for example name, age and phone number. I want to search with the name and phone number. Nothing with the date textView.

See publishResults image

Thanks in advance.

Here is my code :

            if (charString.isEmpty()) {
                // Search is empty/Nothing Entered
                mAppointmentsList = mAppointmentsListFiltered;
            } else {
                List<DataAppointments> filterResults = new ArrayList<>();

                for (DataAppointments data : mAppointmentsList) {
                    if (data instanceof DataPatientDetails) {
                        DataPatientDetails details = (DataPatientDetails) data;

                        if (details.getName().toLowerCase().contains(charString.toLowerCase()) ||
                                details.getPhone().toLowerCase().contains(charString.toLowerCase()) ||
                                details.getId().toLowerCase().contains(charString.toLowerCase())) {
                            filterResults.add(data);

                            if (BuildConfig.DEBUG)
                                Log.d(TAG, "performFiltering: " + details.getName());
                        }
                    }
                }

                mAppointmentsListFiltered = filterResults;
                if (BuildConfig.DEBUG)
                    Log.d(TAG, "performFilteringPatientListFiltered: " + mAppointmentsListFiltered);
            }

            FilterResults results = new FilterResults();
            results.values = mAppointmentsListFiltered;
            results.count = mAppointmentsListFiltered.size();
            if (BuildConfig.DEBUG)
                Log.d(TAG, "performFilteringResultsUpcoming: " + results.count);
            return results;
        }

        @Override
        protected void publishResults(CharSequence constraint, FilterResults results) {
            mAppointmentsListFiltered = (ArrayList<DataAppointments>) results.values;
            if (BuildConfig.DEBUG) Log.d(TAG, "publishResults: " + mAppointmentsListFiltered);
            notifyDataSetChanged();
        }
    };
}`

And my onQueryChangeListener :

    // Query Search in Material Search view
private void querySearch() {
    if (getActivity() != null)
        mSearchView = getActivity().findViewById(R.id.search_view_upcoming);
    mSearchView.setOnQueryTextListener(new MaterialSearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            if (BuildConfig.DEBUG) Log.d(TAG, "onQueryTextSubmit: " + query);
            mAdapter.getFilter().filter(query);
            return false;
        }

        @Override
        public boolean onQueryTextChange(String newText) {
            if (BuildConfig.DEBUG) Log.d(TAG, "onQueryTextChange: " + newText);
            mAdapter.getFilter().filter(newText);
            if (BuildConfig.DEBUG) Log.d(TAG, "onQueryTextChange: " + mAdapter.getItemCount());

            return false;
        }
    });
}

Answer 1

Search is not depends upon view, it is depend upon data. Apply filer upon your list according to your criteria and differentiate your view with viewType.

Answer 2

Based on the code you posted.

in the else statement, I am not exactly sure what is being compared. You can have condition to check if DataAppointments is of type DataPatientDetails and then do your comparision. I am assuming mAppointmentsList is an actual list of data.

else {
 for (DataAppointments data : mAppointmentsList) {
  if (data instanceof DataPatientDetails) {
    DataPatientDetails details = (DataPatientDetails) data;
    // do your comparision here, if it passes, then add to the filtered results
  }
 }
}
