java - Passing one type of data to different places (retrofit) -

i'm new retrofit , have question. want create 1 call server , use downloaded data in different places in app. i'm using viewpager few fragments , each fragment need same data dataresponse class create different views. best way , how like? how retrofit class like. in advance!

public class apiclientfactory {      public static final string baseurl = "https://earthquake.usgs.gov/fdsnws/event/1/";      public apiclient createapiclient(){         retrofit retrofit = new retrofit.builder()                 .baseurl(baseurl)                 .addconverterfactory(gsonconverterfactory.create())                 .build();          return retrofit.create(apiclient.class);     } }  public interface apiclient {      @get("query")     call<dataresponse> getdata(@querymap map<string, string> options); } 

i assume have activity contains viewpager. in activity's oncreate() method can make request. when receive response can build adapter (fragmentpageradapter) , pass dataresponse there. in adapter build fragments , set arguments dataresponse.

the sample code:

public class youractivity extends appcompatactivity {      private fragmentpageradapter madapter;       @override     protected void oncreate(bundle savedinstancestate) {         super.oncreate(savedinstancestate);         ...//          makerequest(); //implement method data     }      //when response received call method     private void onresponse(dataresponse response) {         //create adapter          madapter = new custompageradapter(response, getsupportfragmentmanager());          //don't forget set adapter viewpager     }      static class custompageradapter extends fragmentpageradapter {          dataresponse mresponse;          custompageradapter(dataresponse response, fragmentmanager fm) {             super(fm);             mresponse = response;         }          @override         public fragment getitem(int position) {             //create fragments , set arguments              return customfragment.instance(mresponse);         }          @override         public int getcount() {             return 1; //number of fragments         }     } }  public class customfragment extends fragment {     private static final string key_response = "key_response";      public static customfragment instance(dataresponse response) {         bundle args = new bundle();         args.putparcelable(key_response, response);         customfragment f = new customfragment();         f.setarguments(args);         return f;     }      @override     public void onviewcreated(view root, bundle savedinstancestate) {         super.onviewcreated(root, savedinstancestate);         dataresponse response = getarguments().getparcelable(key_response);          //do response whatever want     } } 

make sure dataresponse implements parcelable interface.
