How to set all values in listview android -
i have created listview. values retrieved json response last values displayed in list.what displaying values in list view.
sixfragment.movielist = new arraylist<movie1>(); (int i1 = 0; i1 < jsonarray3.length(); i1++) { try { jsonobject jsonobject = jsonarray3.getjsonobject(i1); review_rating = jsonobject.optstring("review_rating").tostring(); username_rate = jsonobject.optstring("username").tostring(); review_title = jsonobject.optstring("review_title").tostring(); review_desc = jsonobject.optstring("review_desc").tostring(); sleep = jsonobject.optstring("sleep").tostring(); location = jsonobject.optstring("location").tostring(); service = jsonobject.optstring("service").tostring(); rooms = jsonobject.optstring("rooms").tostring(); cleanliness = jsonobject.optstring("cleanliness").tostring(); userimage1 = jsonobject.optstring("user_image").tostring(); movie1 movie = new movie1(); movie.setrate_userimage(userimage1); movie.setreview_rating(review_rating); movie.setusername_rate(username_rate); movie.setreview_title(review_title); movie.setreview_desc(review_desc); movie.setsleep(sleep); movie.setlocation(location); movie.setservice(service); movie.setraterooms(rooms); movie.setcleanliness(cleanliness); sixfragment.movielist.add(movie); } catch (jsonexception e) { e.printstacktrace(); } } this fragment page:

review adapter
public class reviewadapter extends baseadapter { private final list<movie1> movieitems; public sixfragment context; onefragment fragment; bitmap bitmap; public reviewadapter(sixfragment context, list<movie1> movieitems) { this.context = context; this.movieitems = movieitems; this.fragment=fragment; } public view getview(int position, view convertview, viewgroup parent) { if (convertview == null) { layoutinflater inflater = layoutinflater.from(parent.getcontext()); convertview = inflater.inflate(r.layout.fragment_sixlist,parent,false); circleimageview profile_image = (circleimageview) convertview.findviewbyid(r.id.profile_image); textview rate_username = (textview) convertview.findviewbyid(r.id.rate_username); ratingbar ratingbar = (ratingbar) convertview.findviewbyid(r.id.ratingbar); textview rate_title = (textview) convertview.findviewbyid(r.id.rate_title); textview rate_description = (textview) convertview.findviewbyid(r.id.rate_description); ratingbar ratingbar_sleep = (ratingbar) convertview.findviewbyid(r.id.ratingbar_sleep); ratingbar ratingbar_location = (ratingbar) convertview.findviewbyid(r.id.ratingbar_location); ratingbar ratingbar_service = (ratingbar) convertview.findviewbyid(r.id.ratingbar_service); ratingbar ratingbar_clearness = (ratingbar) convertview.findviewbyid(r.id.ratingbar_clearness); ratingbar ratingbar_rooms = (ratingbar) convertview.findviewbyid(r.id.ratingbar_rooms); final movie1 m = movieitems.get(position); // glide.with(context) // .load(m.getrate_userimage()) // .diskcachestrategy(diskcachestrategy.all) // .into(profile_image); url url = null; string image=m.getrate_userimage(); try { url = new url(image); inputstream = null; // bitmap bitmap = bitmapfactory.decodestream(is); //create imageview dynamically glide.with(context).load(string.valueof(url)).into(profile_image); } catch (malformedurlexception e) { e.printstacktrace(); } //glide.with(context).load(string.valueof(url)).into(profile_image); if (m.getusername_rate()!=null) { if (!m.getusername_rate().equals("null")) { rate_username.settext(m.getusername_rate()); }} if (m.getreview_rating()!=null) { if (!m.getreview_rating().equals("null")) { ratingbar.setrating(float.parsefloat(m.getreview_rating())); }} if (m.getsleep()!=null) { if (!m.getsleep().equals("null")) { ratingbar_sleep.setrating(float.parsefloat(m.getsleep())); }} } return convertview; } @override public int getcount() { return movieitems.size(); } @override public object getitem(int location) { return movieitems.get(location); } @override public long getitemid(int position) { return position; } }
in fragment make list static:
public class sixfragment extends fragment{ // code //------------do this------------------/// public static list<movie1> movielist = new arraylist<movie1>(); public sixfragment() { // required empty public constructor } //your code } rest of code in fragment is.
change json loop :
sixfragment.movielist = new arraylist<movie1>(); (int i1 = 0; i1 < jsonarray3.length(); i1++) { try { jsonobject jsonobject = jsonarray3.getjsonobject(i1); review_rating = jsonobject.optstring("review_rating").tostring(); username_rate = jsonobject.optstring("username").tostring(); review_title = jsonobject.optstring("review_title").tostring(); review_desc = jsonobject.optstring("review_desc").tostring(); sleep = jsonobject.optstring("sleep").tostring(); location = jsonobject.optstring("location").tostring(); service = jsonobject.optstring("service").tostring(); rooms = jsonobject.optstring("rooms").tostring(); cleanliness = jsonobject.optstring("cleanliness").tostring(); userimage1 = jsonobject.optstring("user_image").tostring(); movie1 movie = new movie1(); movie.setrate_userimage(userimage1); movie.setreview_rating(review_rating); movie.setusername_rate(username_rate); movie.setreview_title(review_title); movie.setreview_desc(review_desc); movie.setsleep(sleep); movie.setlocation(location); movie.setservice(service); movie.setraterooms(rooms); movie.setcleanliness(cleanliness); sixfragment.movielist.add(movie); } catch (jsonexception e) { e.printstacktrace(); } }
