java - Android: Displaying days since received message after 24 hours pass -

-

i have implemented following code in android app splits the date/time value retrieved sql , displays number of minutes/hours since message received: 

//splits date , time string retrieved sql 2 separate strings,  //and stores them array string[] dt_array = m1.gettime().split(" "); //string date = dt_array[0];  string time = dt_array[1];    //splits time 2 strings, 1 hours , 1 minutes, , stores them //into array string[] timesplit = time.split(":"); string hourstring = timesplit[0];  string minutestring = timesplit[1];  //converts new separate time strings integer variables int msghour = integer.parseint(hourstring); int msgminute =integer.parseint(minutestring);  calendar currenttime = calendar.getinstance();  //retrieves current hour , minute device , stores in separate ints  int currenthour = currenttime.get(calendar.hour); int currentminute = currenttime.get(calendar.minute);  int hourssince;  int minutessince; string timedisplay = null;   if (currenthour != 1) {     //tells app display minutes if message received under hour ago     if(currenthour - msghour < 1)     {          minutessince = currentminute - msgminute;         //if minute has passed, text should read "1 minute ago", otherwise use plural "minutes"         if (minutessince == 1)             timedisplay = minutessince + " minute ago";         else             timedisplay = minutessince + " minutes ago";     }     else if (currenthour - msghour >= 1)     {         hourssince = currenthour - msghour;         timedisplay = hourssince + " hours ago";     }  }  else {     //for messages received @ 12th hour, if hour 1, correctly displays 1 hour ago     if(msghour == 12 && currenthour == 1)     {         hourssince = 1;         timedisplay = hourssince + " hours ago";     }  }

what want add function displays days since received if hour count goes above 24. know should easy, i'm not sure how go on android.

your method of determining amount of time since message posted on complicated , prone issues when minutes , hours roll over. more simple:

simpledateformat formatter = new simpledateformat("dd/mm/yyyy hh:mm"); //change format needed date messagedate = formatter.parse(date); long since = system.currenttimemillis() - messagedate.gettime(); long seconds = since/1000; long minutes = seconds/60; long hours = minutes/60; long days = hours/24;

and there, building message want should trivial you.

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
