Such a situation, using Filterable , during the search, first used the Activity , but then it was necessary to use a fragment. I will not go into the structure of the code, but the method call occurs in the custom adapter.
@Override public Filter getFilter() { return ((MainActivity) mContext).new ListFilter(); } This code is located in the adapter when I use the Activity , but if I use a fragment, I can’t understand how I can redo this method so that it works correctly. And yes, ListFilter() is an inner class that inherits from Filter . How do I implement a similar method in the fragment?
