java - holder returning wrong view -


i uploading list server. showing through 'adapter'. loading image of every list element in background.

after loading every images calling notifydatasetchanged() adapter , accordingly getview() has been called refresh every image each list element.

problem have updated image last list element. understanding "holder = (viewholder) rowview.gettag();" returning holder view.

but if uncommenting 2 lines below:

//                holder.textview = (textview) rowview.findviewbyid(r.id.tvappname); //                holder.imageview = (imageview) rowview.findviewbyid(r.id.ivimage);  getting expected result; don't want call findviewbyld.       private static class viewholder {         public imageview imageview;         public textview textview;         public int rowcount = 0;     }         public view getview(int position, view convertview, viewgroup parent) {              view rowview = convertview;             if (rowview == null) {                 layoutinflater inflater = getlayoutinflater();                 rowview = inflater.inflate(r.layout.applist_item, null, true);                  holder.textview = (textview) rowview.findviewbyid(r.id.tvappname);                 holder.imageview = (imageview) rowview.findviewbyid(r.id.ivimage);                 rowview.settag(holder);             } else {                 holder = (viewholder) rowview.gettag(); //                holder.textview = (textview) rowview.findviewbyid(r.id.tvappname); //                holder.imageview = (imageview) rowview.findviewbyid(r.id.ivimage);             }              apkdata app = getitem(position);             holder.textview.settext(app.getappname());              drawable mpic = loadimage(app);             holder.imageview.setimagedrawable(mpic);              return rowview;         }      private drawable loadimage(final apkdata item) {             if (item.geticonimage() != null) {                 log.v(constants.tag, "item.geticonimage() != null");                 return item.geticonimage();             } else {                 log.v(constants.tag, "item.geticonimage() == null");             }              mexecutor.execute(new runnable() {                 @override                 public void run() {                      if (!(thread.currentthread().isinterrupted())) {                         drawable res = null;                         bitmap image = null;                         int trycount = 0;                         while ((image == null) && (trycount <= constants.try_connecction)) {                             image = utils.loadimage(item.geticonpath(),                                     holder.imageview.getlayoutparams().height,                                     holder.imageview.getlayoutparams().width);                             trycount++;                         }                         if (image != null) {                             res = new bitmapdrawable(getresources(), image);                         }                          if (res == null) {                             res = getresources().getdrawable(r.drawable.android_app_icon_logo);                         }                          item.seticonimage(res);                          asyncnotifydatachanged();                     }                 }             });             return getresources().getdrawable(r.drawable.android_app_icon_logo);         }      //utils.loadimage:     public static bitmap loadimage(string urlstr, int height, int width) {         if (!urlstr.startswith("http://") && !urlstr.startswith("https://"))             urlstr = "http://" + urlstr;         url url;         try {             url = new url(urlstr);             bitmap mimg = null;             mimg = bitmapfactory.decodestream(url.openconnection().getinputstream());             return scaleimage(mimg, height, width);         } catch (malformedurlexception e) {             log.e(constants.tag, "loadimage malformedurlexception:", e);             return null;         } catch (ioexception e1) {             log.e(constants.tag, "loadimage ioexception:", e1);             return null;         } catch (nullpointerexception ex) {             log.e(constants.tag, "loadimage nullpointerexception:", ex);             return null;        }     }

you have create holder every view...

... rowview = inflater.inflate(r.layout.applist_item, null, true); viewholder holder = new viewholder(); holder.textview = (textview) rowview.findviewbyid(r.id.tvappname); ....

vb.net - Virtual Keyboard commands -

i wondering difference between virtual these keyboard commands is: keyeventf_extendedkey , keyeventf_keyup is. everywhere have looked gives me description based off integers , not want know each of them does. you've tagged question vb.net, these have nothing @ vb.net. they're constants defined in windows header files, use win32 api functions. as far difference, can't tell looking @ values. individual values not particularly important, that's why named identifiers used. what's important used , documentation functions tells mean. the first one, keyeventf_extendedkey , used keybdinput structure (which used along e.g. sendinput function) pass information synthesized keyboard input. if flag used, means scan code should interpreted extended key. technically, means scan code preceded prefix byte value 224 (&he0 in hexadecimal notation). the second one, keyeventf_keyup , 1 of flags available use structure. means key being released (going up)...
