I have to display data in Listview in android. For that I am retrieving data from sqlite database, having two column fields "date" and "amount". There are some more column fields but i don't need them. Now I want to show data in Listview weekly basis, with addition of the amount for the given week. Can anyone Please help me. How can I do this.(I thought of using strftime() function also but it add all the previous weeks data in one row. even thought for using Calendar class of java but don't know how can I achieve the solution using that.)
If I understand correctly your only problem is to make sure that a week has passed. If so:
I refer you to this solution: (Java / Android) Calculate days between 2 dates and present the result in a specific format , that uses no external Java libraries. You can just save the former list population day, the current day, and use the solution here to get the distance between them in days. Then all that remains is to check if the result >= 7. if so, a week has passed.

I want to create a UI to enable the user to set specific configuration from date1 to date2. To pick the dates I want the calendar to pop up.
To create the calendar, I can put a combo box to choose the month, along with 30 buttons as representative of the days (enabling/disabling some days based on the selected month).
If you know a better way to do this, I would be very thankful if you share it with me!
Thanks!
Please don't do it like that. You have the full power of Java at your hands. There are many Java libraries for date pickers like this one:

Download the .jar file and add it to your model dependencies. Then you can create the date picker object using the respective API.
Here is an AnyLogic example model but it currently only works in AnyLogic 7 (since 8 massively changed how things are displayed). To get it working in AL 8, you might need to ask AL support.
Not a problem per se but I am figuring out how to do something. In my app, I shall save some workout for every specific client. Any workout will be doing different from week to week; i.e: rep scheme in the week one shall be different from the week two, and so on.
So, how to show the user that in the calendar? Should I save in every workout the day it should be performed and then see if it's the same day and show it? Or how to implement this? The only way I thought to implement this is save in every workout the day that it should be performed and show it in a textview and all the info behind relationated with the workout without calendar use but don't know if this approach would be the best
I have searched on the web but found nothing. If you could give me a hint would be awesome.
Thanks in advance!
I have created a resturaunt app for android in Android studio. I am using firebase to store the data. Each month i will bill the resturaunt 1 dollar per order made via the app. So i need some way to register each order and sort it by month. This has me kinda stumped so i don't want to release yet. Any help would be deeply appreciated.
What i would like is to have a table "Orders" with the 12 months. And i want to store a variable "amount" for each month. Like in the image below here:

whenever an order is submitted i want to get the value of "amount" for the specific month and then increase it by 1. This was the only way i could think of, i am sure there would be better ways and i am very open to suggestions.
I would like to create a graph using data from a database (Oracle).
The dataset contains DateTimeStamp values and numeric values
The DateTimeStamp values are for intervals of 15 minutes and usually extend for a period greater than one calendar day.
The DateTimeStamp values need to be graphed against the X-axis and the data values (numeric) will be graphed against the Y-yxis.
The x-axis major tic marks should be the calendar days.
I have purchased the enterprise version of JFreeChart but the username password provided does not allow me to ask questions on their forum, and sending email to the owner results in no response.
Thanks for any help you can offer. A working code block/snippet would be ideal and much appreciated.
Look at JDBCXYDataset, which uses the query's ResultSetMetaData to recognize Types related to date and time. Complete examples are seen here and here.
As an aside, access to the support forum is free; just click the register link.
I have already a table with three time fields. One to register the hour when the user start working, when stop working and the difference. Now I want to add the day of the week(Mon-Sun) and the date. How can I properly do that, saying that then I will want to grab the hours that the user worked in the past 7 days, lets say.
I've read that timestamp give all the information but I don't know whether I can separate days from date?
**table name = date_time
date_time_id = auto increment
user_id = var
time_in = time
time_out = time
time_dif = time**
ps: I am using java(servlets) and mysql.
Thanks guys
when I start getting really silly with yime in MySql, I use unix time. MySql has built in functions for unix time conversion, too. FROM_UNIXTIME() is one of them. Here's url of a reference page I use.
I've been burned by MySql time (probably more by my own confusion) a few times, so I prefer unix time and then I can manually figure things out by factoring seconds into minutes *60 and hours *60*60 and days *24*60*60.
Change your column types to TIMESTAMP instead of TIME. A timestamp includes both a date and a time.
You should hav column datetime type So you can easily get days month week whatever required.
Here all functions listed you can use as desired with datetime field:
Date and Time Functions
Use org.joda Datetime java library. Its very easy and you can do all the calculations using timestamp.
