android - Image not loading with Picasso using Rx Observable and Retrofit2 -
i learning rxjava (observable) , retrofit2. landed in situation picasso not loading images url. details below:
public class intentkeys { public static final long interceptor_timeout = 15; public static final string popular_movies_service_endpoint = "http://api.themoviedb.org/3/"; public static final string popular_movies_poster_endpoint = "http://image.tmdb.org/t/p/w300/"; public static final string popular_movies_api_key = "key"; } the recyclerview adapter:
public class gridviewadapter extends recyclerview.adapter<gridviewadapter.gridvieholder> { private static final string tag = gridviewadapter.class.getsimplename(); private static final int span_count = 2; private static final float thumbnail_ratio = 1.5f; private list<result> movies = new arraylist<>(); private context context; public gridviewadapter(list<result> movies, context context) { this.movies = movies; this.context = context; } @override public gridvieholder oncreateviewholder(viewgroup parent, int viewtype) { view view = layoutinflater.from(parent.getcontext()).inflate(r.layout.movies_grid_view, parent, false); // view.getlayoutparams().height = (int) (parent.getwidth() / span_count * thumbnail_ratio); return new gridvieholder(view); } @override public void onbindviewholder(gridvieholder holder, int position) { gridvieholder posterholder = (gridvieholder) holder; posterholder.bind(movies.get(position)); /* result popularmovies = movies.get(position); string movieposter = popularmovies.getposterpath(); string movieposterurl = intentkeys.popular_movies_poster_endpoint + movieposter; picasso.with(context).load(movieposterurl.trim()) .config(bitmap.config.rgb_565) .into(posters);*/ } @override public int getitemcount() { return movies.size(); } public class gridvieholder extends recyclerview.viewholder { imageview posters; public gridvieholder(view itemview) { super(itemview); posters = (imageview) itemview.findviewbyid(r.id.movies_poster_grid_view); } public void bind(final result result) { uri uri = uri.parse(intentkeys.popular_movies_poster_endpoint).buildupon() .appendpath(imagesize.w185.getvalue()) .appendpath(result.getposterpath().replace("/", "")) .build(); picasso.with(itemview.getcontext()).load(uri).into(posters); } } } below, how have defined service , retrofit manager:
public interface popularmoviesservice { @get("movie/popular") observable<result> getpopularmovies(@query("api_key") string apikey); } public class popularmoviesretrofitmanager { private popularmoviesservice service; private static retrofit retrofit = null; private static httplogginginterceptor getlogginginterceptor() { httplogginginterceptor interceptor = new httplogginginterceptor(); interceptor.setlevel(httplogginginterceptor.level.body); return interceptor; } private static okhttpclient getokhttpclient(httplogginginterceptor logginginterceptor) { return new okhttpclient.builder() .addinterceptor(logginginterceptor) .connecttimeout(intentkeys.interceptor_timeout, timeunit.seconds) .readtimeout(intentkeys.interceptor_timeout, timeunit.seconds) .build(); } public static retrofit getmoviesclient() { okhttpclient client = getokhttpclient(getlogginginterceptor()); if (retrofit == null) { retrofit = new retrofit.builder() .baseurl(intentkeys.popular_movies_service_endpoint) .addconverterfactory(gsonconverterfactory.create()) .addcalladapterfactory(rxjavacalladapterfactory.create()) .client(client) .build(); } return retrofit; } } finally adapter , fragment classes. in activity class, have getsupportfragmentmanager() load fragment.
public class gridviewadapter extends recyclerview.adapter<gridviewadapter.gridvieholder> { private static final string tag = gridviewadapter.class.getsimplename(); private static final int span_count = 2; private static final float thumbnail_ratio = 1.5f; private list<result> movies = new arraylist<>(); private context context; public gridviewadapter(list<result> movies, context context) { this.movies = movies; this.context = context; } @override public gridvieholder oncreateviewholder(viewgroup parent, int viewtype) { view view = layoutinflater.from(parent.getcontext()).inflate(r.layout.movies_grid_view, parent, false); // view.getlayoutparams().height = (int) (parent.getwidth() / span_count * thumbnail_ratio); return new gridvieholder(view); } @override public void onbindviewholder(gridvieholder holder, int position) { gridvieholder posterholder = (gridvieholder) holder; posterholder.bind(movies.get(position)); /* result popularmovies = movies.get(position); string movieposter = popularmovies.getposterpath(); string movieposterurl = intentkeys.popular_movies_poster_endpoint + movieposter; picasso.with(context).load(movieposterurl.trim()) .config(bitmap.config.rgb_565) .into(posters);*/ } @override public int getitemcount() { return movies.size(); } public class gridvieholder extends recyclerview.viewholder { imageview posters; public gridvieholder(view itemview) { super(itemview); posters = (imageview) itemview.findviewbyid(r.id.movies_poster_grid_view); } public void bind(final result result) { uri uri = uri.parse(intentkeys.popular_movies_poster_endpoint).buildupon() .appendpath(imagesize.w185.getvalue()) .appendpath(result.getposterpath().replace("/", "")) .build(); picasso.with(itemview.getcontext()).load(uri).into(posters); } } } public class popularmoviesfragment extends fragment { private static final string tag = popularmoviesfragment.class.getcanonicalname(); private gridviewadapter gridviewadapter; private list<result> resultitems = new arraylist<>();; private subscription moviesubscription; private recyclerview recyclerview; private popularmoviesservice service = popularmoviesretrofitmanager.getmoviesclient().create(popularmoviesservice.class); public popularmoviesfragment() { } @override public void onattach(context context) { super.onattach(context); } @override public view oncreateview(layoutinflater inflater, viewgroup container, bundle savedinstancestate) { view view = inflater.inflate(r.layout.fragment_popular_movies, container, false); recyclerview = (recyclerview) view.findviewbyid(r.id.popular_movies_recycler_view); recyclerview.sethasfixedsize(true); recyclerview.layoutmanager layoutmanager = new gridlayoutmanager(getcontext(), 2); recyclerview.setlayoutmanager(layoutmanager); gridviewadapter = new gridviewadapter(resultitems, getcontext()); recyclerview.setadapter(gridviewadapter); return (view); } @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); sethasoptionsmenu(true); } @override public void onstart() { super.onstart(); getmoviessubscription(); } private void getmoviessubscription() { moviesubscription = service.getpopularmovies(intentkeys.popular_movies_api_key) .subscribeon(schedulers.io()) .observeon(androidschedulers.mainthread()) .subscribe( new action1<result>() { @override public void call(result popularmovies) { } }, new action1<throwable>() { @override public void call(throwable throwable) { } }, new action0() { @override public void call() { displayposters(); log.i(tag, "getmoviessubscription: completed"); } } ); } @override public void ondestroyview() { super.ondestroyview(); if (moviesubscription != null && moviesubscription.isunsubscribed()) { moviesubscription.unsubscribe(); } } private void displayposters() { gridviewadapter = new gridviewadapter(resultitems, getcontext()); recyclerview.setadapter(gridviewadapter); recyclerview.invalidate(); } } the problem is, picasso not loading images in gridview api call. here highly appreciated.
