i downloading images parse.com. never know amount of images have using counter retrieve them. reason, counter gets 5, , downloads image 5 times. in storage, have 1 image. here code:

string root = environment.getexternalstoragedirectory().tostring(); int = 0;

retrieve images:

parsequery<parseobject> query = parsequery.getquery("fightgallery");     query.findinbackground(new findcallback<parseobject>() {         @override         public void done(list<parseobject> parseobjects, com.parse.parseexception e) {             if (e == null) {                  int size = parseobjects.size();                 log.d("query size", "size " + size + " int " + i);                 while (i < size) {                     parsefile fileobject = parseobjects.get(i).getparsefile("image");                      fileobject.getdatainbackground(new getdatacallback() {                         @override                         public void done(byte[] bytes, parseexception e) {                             if (e == null) {                                 log.d("data", "we have data " +i);                                  bitmap bmp = bitmapfactory.decodebytearray(bytes, 0, bytes.length);                                 saveimagesinsdcard(bmp, i);                               } else {                                 log.d("error: ", "" + e.getmessage());                                 progressdialog.dismiss();                             }                         }                     });                     i++;                 }             } else {                 log.d("error:", "" + e.getmessage());                 progressdialog.dismiss();             }         }     });

this saveimagesinsdcard()

 private void saveimagesinsdcard(bitmap bmp, int i) {       file mydir = new file(root + "/clash_images");     mydir.mkdirs();     string fname = "image";     file file = new file(mydir, fname+i+".jpg");    // if (file.exists()) file.delete();     log.d("image", "saved " +fname + i);      try {         fileoutputstream out = new fileoutputstream(file);         bmp.compress(bitmap.compressformat.png, 90, out);         out.flush();         out.close();      } catch (filenotfoundexception e1) {         e1.printstacktrace();     } catch (ioexception e2) {         e2.printstacktrace();     }   }

here logcat showing log.d

as can see, in logcat, i never changes 5. how structure download 5 images?

when getdatacallback executed after file downloaded, loop has run 5 times , such value of i 5 every time.

Image
i've plotted data points , fitted exponential curve between them using 'fit' in matlab. problem fit-function got fitted line wanted plot, markers on top of regular markers. solved problem plotting wanted markers on top of unwanted couldn't seen. problem. when want show legends dots in there. how can remove markers legend without removing fitted line since both of them hidden inside fit-function? can stop 'fit' plotting unwanted markers? so, want remove blue dot called 'hoff' in picture below. you can leave out legend-entries manually leaving out handles of lines, dont want in legend. try this: %if plot something, want showing in legend, save handle: h_line = plot(x,y) %you dont want show line? dont anything, plot it: plot(mymarker) %then set legend-> can add text legend-entries %a cell-array containing strings want show up: legend([h_line another_line],{'text1' 'text2'}) with example (see comments) came solution: ...

java - Why does my date parsing return a weird date? -

-
here code using: string string = "08/07/2013".replace('/', '-'); date date = new simpledateformat("yyyy-mm-dd").parse(string); why date return: "wen jan 3 00:00:00 est 14"? not @ date format told use. edit: need format because database using requires format. the format use parse date string, not match it. using yyyy 08 . use following format: new simpledateformat("dd-mm-yyyy") and why @ replacing / - ? can build pattern original string only: string string = "08/07/2013" date date = new simpledateformat("dd/mm/yyyy").parse(string); and if want date string in yyyy-mm-dd format, can format date using dateformat#format(date) method: string formatteddate = new simpledateformat("yyyy-mm-dd").format(date); see also: change date format in java string simpledateformat java doc
