java - Adapters not output image(android) -


sorry english. using adapter, , may wrong somthing using it. trying show image , textview output. textview coming in output, image not. please me, try many many times fix it. load image in downloadimagetask. in downloadimagetask have class imageloader, have used this tutorial. don't have error, have nothing(

arraylist<news> arraylistnews; int resourse; context context; layoutinflater vi;  public newsadapter(context context, int resource, arraylist<news> objects) {     super(context, resource, objects);      arraylistnews = objects;     resourse = resource;     this.context = context;      vi = (layoutinflater) context.getsystemservice(context.layout_inflater_service); }  @override public view getview(int position, view convertview, viewgroup parent) {      viewholder holder;     if(convertview == null) {         convertview = vi.inflate(resourse, null);         holder = new viewholder();          holder.imageview = (imageview) convertview.findviewbyid(r.id.imagenews);         holder.namenews = (textview) convertview.findviewbyid(r.id.namenews);         holder.daynews = (textview) convertview.findviewbyid(r.id.daynews);          convertview.settag(holder);     } else {         holder = (viewholder) convertview.gettag();     }      new downloadimagetask(holder.imageview).execute(arraylistnews.get(position).getimagenews());     holder.namenews.settext(arraylistnews.get(position).getnamenews());     holder.daynews.settext(arraylistnews.get(position).getdaynews());      return convertview; }  static class viewholder {     public imageview imageview;     public textview namenews;     public textview daynews; }     //this class set image private class downloadimagetask extends asynctask<string, void, string> {     imageview bmimage;      imageloader imgloader;      public downloadimagetask(imageview bmimage) {         this.bmimage = bmimage;     }      @override     protected string doinbackground(string... urls) {         string urldisplay = urls[0];         return urldisplay;      }      protected void onpostexecute(string result) {          imgloader = new imageloader(context.getapplicationcontext());         imgloader.displayimage(result, bmimage);      }  }

i suggest use picasso library. easy use. add dependency(android studio) or add .jar file library(in eclipse).

picasso.with(context).load("http://i.imgur.com/dvpvklr.png").into(imageview);

that's it. not need asynctask download images.

your getview() be

@override public view getview(int position, view convertview, viewgroup parent) {      viewholder holder;     if(convertview == null) {         convertview = vi.inflate(resourse, null);         holder = new viewholder();          holder.imageview = (imageview) convertview.findviewbyid(r.id.imagenews);         holder.namenews = (textview) convertview.findviewbyid(r.id.namenews);         holder.daynews = (textview) convertview.findviewbyid(r.id.daynews);          convertview.settag(holder);     } else {         holder = (viewholder) convertview.gettag();     }      // not sure return value of arraylistnews.get(position).getimagenews();      // should url pointing image file     picasso.with(context).load(arraylistnews.get(position).getimagenews()).into(holder.imageview);      holder.namenews.settext(arraylistnews.get(position).getnamenews());     holder.daynews.settext(arraylistnews.get(position).getdaynews());      return convertview; }

utf 8 - split utf-8 string into bytes in python -

i trying split utf-8 string bytes in python 3. problem is, when use bytearray, byte, encode etc functions array size of element 14 bytes, not 1 byte expected. need split text file sequence of bytes , send them byte after byte using sockets. tried this: infile = open (file, "r") str = infile.read() byte_str = bytes(str, 'utf-8') print("size of byte_str",sys.getsizeof(byte_str[0])) print gives me 14, need 1... suggestion? quoting official documentation : sys.getsizeof(object[, default]) return size of object in bytes. object can type of object. built-in objects return correct results, not have hold true third-party extensions implementation specific. only memory consumption directly attributed object accounted for, not memory consumption of objects refers to. if given, default returned if object not provide means retrieve size. otherwise typeerror raised. getsizeof() calls object’s __sizeof__ method , adds ...
