How to add a search filter in RecyclerView to filter through parsed JSON data? edited

Question

I am developing an android app which shows a list of countries affected by Coronavirus , the total number of confirmed cases and total Deaths. I am using a JSON API

Answer 1

The problem is with below initialization in the MainActivity.Oncreate method

mCorona_Stats_Adapter = new Corona_Stats_Adapter(this,countries);

Initialize the adapter in onPostExecute method with updated countries data.

Hope this will help you.

Answer 2

You have to set arraylist to update country data in adapter after getting data from the server.

Public void setCoronaData (Arraylist coronaData) {
  countryList = coronaData;
  notifyDataSetChanged ();
}
