android - Passing searching data to Searchable Activity -

i have main activity has 2 fragments. main activity has searchview in action bar. both fragments have list of large number of strings, list<string>.

the flow is:

user enters fragment --> selects string (lets selection1) --> based on selection1 list of strings populated in second fragment --> here user selects second string ---> processing based on these 2 strings.

now since both fragments contain large number of strings, user enters query in searchview, filters list , reduces smaller list displayed in searchableactivity.

now problem how searchableactivity access these 2 list<string> filter them based on query , display reduced list user.

currently have done overridden onsearchrequested , pass data as

    @override     public boolean onsearchrequested()     {         bundle appdata = new bundle();         appdata.putstring(fragment_id, "fragment_a");         appdata.putstringarraylist(search_list, searchlist);         startsearch(null, false, appdata, false);         return true;     } 

is there better way or standard way problem can handled i.e. implementation allows data based mainactivity searchableactivity?

edit: adding code. showing how data set in fragment. ondatareceived called httpmanager receives data.

@override public void ondatareceived(string type,final object object) {     switch(type)     {         case popitconstants.update_list:             getactivity().runonuithread(new runnable() {                 @override                 public void run()                 {                     updatecinemalist((list<string>) object);                 }             });             break;     } }  public void updatedatalist(list<string> data) {     this.datalist = data;     spinner.setvisibility(view.gone);     madapter.updatelist(datalist); } 

i answered similar question few minutes ago, @ how can send list activity in android studio

i encourage rethink pattern of passing data around among activities , fragments. consider creating 1 or more data models (non-android classes) application, , making these models available android classes (activities, fragments, etc.) need them.

remove of data storage , manipulation code activities , fragments, , put model(s).
