java - How to add multiple arrays to recyclerview -
package com.example.sander.app; import android.app.fragment; import android.content.intent; import android.os.bundle; import android.support.v7.widget.cardview; import android.support.v7.widget.linearlayoutmanager; import android.support.v7.widget.recyclerview; import android.view.layoutinflater; import android.view.menu; import android.view.menuinflater; import android.view.menuitem; import android.view.view; import android.view.viewgroup; import android.widget.framelayout; import android.widget.textview; import com.android.volley.request; import com.android.volley.requestqueue; import com.android.volley.response; import com.android.volley.volleyerror; import com.android.volley.toolbox.stringrequest; import com.android.volley.toolbox.volley; import org.json.jsonarray; import org.json.jsonexception; import org.json.jsonobject; import java.util.arraylist; import java.util.collections; import java.util.list; /** * created sander on 6-4-2017. */ public class recycleframe extends fragment { arraylist<string> names = new arraylist<>(); arraylist<integer> cpoints = new arraylist<>(); boolean sort = false; public recycleframe() { // required empty public constructor } @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); } @override public void oncreateoptionsmenu(menu menu, menuinflater inflater) { inflater.inflate(r.menu.fragment_view, menu); super.oncreateoptionsmenu(menu,inflater); } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { sethasoptionsmenu(true); // inflate layout fragment view view = inflater.inflate(r.layout.fragment_recycle, container, false); final recyclerview vrecyclerview = (recyclerview) view.findviewbyid(r.id.rv_recycler_view); requestqueue rq = volley.newrequestqueue(getactivity().getapplicationcontext()); string url= "http://test.dontstealmywag.ga/api/parkgarage_all.php"; stringrequest stringrequest = new stringrequest(request.method.get, url, new response.listener<string>() { @override public void onresponse(string response) { // response try{ jsonobject o = new jsonobject(response); jsonarray values=o.getjsonarray(""); ( int i=0; i< values.length(); i++) { jsonobject jsonobject = values.getjsonobject(i); names.add(jsonobject.getstring("parkgarage_name")); cpoints.add(jsonobject.getint("charging_capacity")); // want add recycler viewer } } catch (jsonexception ex){} collections.sort(names); vrecyclerview.sethasfixedsize(true); recycleadapter adapter = new recycleadapter(names, cpoints); vrecyclerview.setadapter(adapter); linearlayoutmanager llm = new linearlayoutmanager(getactivity()); vrecyclerview.setlayoutmanager(llm); } }, new response.errorlistener() { @override public void onerrorresponse(volleyerror error) { // handle error } }); rq.add(stringrequest); return view; } } this code recyclerframe, in here can see cpoints.add(jsonobject.getint("charging_capacity")); want display inside recyclerviewer, can display names array.
this recycleradapter code:
package com.example.sander.app; import android.app.fragment; import android.media.image; import android.os.bundle; import android.support.v7.widget.cardview; import android.support.v7.widget.linearlayoutmanager; import android.support.v7.widget.recyclerview; import android.view.layoutinflater; import android.view.view; import android.view.viewgroup; import android.widget.imageview; import android.widget.textview; import java.util.arraylist; /** * created sander on 6-4-2017. */ public class recycleadapter extends recyclerview.adapter<recycleadapter.myviewholder> { arraylist<string> arraydataset; arraylist<integer> arraydataset2; public static class myviewholder extends recyclerview.viewholder{ public cardview mcardview; public textview mtextview; public textview mtextview2; public imageview mimageview; public myviewholder(view v){ super(v); mcardview = (cardview) v.findviewbyid(r.id.card_view); mtextview = (textview) v.findviewbyid(r.id.tv_blah); mtextview2 = (textview) v.findviewbyid(r.id.tv_blah2); mimageview = (imageview) v.findviewbyid(r.id.imageview1); } } public recycleadapter(arraylist<string> names, arraylist<integer> cpoints){ arraydataset = names; arraydataset2= cpoints; } @override public recycleadapter.myviewholder oncreateviewholder(viewgroup parent, int viewtype){ view v = layoutinflater.from(parent.getcontext()).inflate(r.layout.fragment_card_view, parent, false); myviewholder vh = new myviewholder(v); return vh; } @override public void onbindviewholder(myviewholder holder, int position){ holder.mtextview.settext(arraydataset.get(position)); holder.mtextview2.settext(arraydataset2.get(position)); holder.mimageview.setimageresource(r.drawable.ic_local_parking_black_24dp); } @override public int getitemcount() { return arraydataset.size(); } } i know changes need made here don't know how to. i've read dataset class don't know how implement it. tell me how can add multiple arrays recyclerview?

replace these
arraylist<string> names = new arraylist<>(); arraylist<integer> cpoints = new arraylist<>(); with
static class point { string name; int points; } list<point> points = new arraylist<>(); and make recyclerview use point class instead of needing more 1 list.
private list<point> mpoints; public recycleadapter(list<point> points){ mpoints = points; } ideally, use gson create java objects directly json.
