Pop Up Date Picker Android Studio Tutorial
Pop Up Date Picker Android Studio Tutorial
Simple date picker tutorial. Todays example project is how to create a simple pop-up date picker in Android studio using Java.
In this beginner friendly tutorial, we create a button which when tapped displays and Date Picker Dialog which is a pop up with a date picker. Once the user selects a date from the spinner date picker we format the selected date and put the text of our formatted date into the text of our button.
In this tutorial we use a spinner style for our date picker, but the concepts here should work for any date picker styling.

0.32 -> hello and welcome to another java and android
studio tutorial my name is cal and in this
4.08 -> tutorial we're going to be having a look at date
pickers we're just going to create a very simple
8 -> pop-up date picker so basically we're going to
have a button when you click on the button it's
12.4 -> going to show up then alert dialog with the
date picker in it the user then selects the
16.48 -> date and then we put that date back into the
buttons text really simple shouldn't take too
21.44 -> long there's a link in the description to the
source code with all that said let's get started
29.76 -> getting started i'm just going to create a
new android studio project empty activity i'm
33.28 -> going to call this date picker tutorial and our
programming language is java and hit finish to
38.24 -> create our new android studio project next i'm
going to head into our themes and just delete
43.68 -> all of the values just because that's a new
android studio thing that they've put in there
47.76 -> and just keeping this as simple as possible i'm
going to remove all that heading back into the
52 -> main xml i'm just going to add in an id to our
textview changing the text to date and the text
58.32 -> size to 30sp the text color is black and i'm going
to remove that top constraint there so that the
64.32 -> text view aligns at the top and then just say
margin top 30dp and i'm actually going to change
68.8 -> that to select date it's a bit nice a bit of
text there and then i'm going to add in a button
72.56 -> i'm going to give it a width of 250dp as well as
height wrap content and then i'm going to give it
77.04 -> a text of January 1st 2020 text size 30 and color
black as well and then i'm just going to say style
83.92 -> and then i'm going to give it a question mark and
say android spinner style and then i'm going to
87.76 -> copy down those two constraints to the left option
to the right of parent just so it centers in the
94.16 -> view and then i'm also going to give it the
constraint top to bottom of our text view
99.12 -> as well as margin top 10 dp cool and finally
we're just going to give our button an id
102.96 -> calling it date pick a button as well as an on
click listener so just saying on click say open
107.92 -> date picker click on the error message and create
that in the main activity cool and then heading
112.64 -> up to the top of our main activity we're going
to declare a date picker dialog and i'm just
116.4 -> naming this date picker dialog as well as a button
just going to call this date button then in our
121.36 -> own create method we're going to create another
method called init date picker below that method
125.68 -> we're just going to say date button is equal
to find view by id and then r dot id dot date
130.48 -> picker button which is the same id that we gave
in the xml and then in our init date pickup method
134.56 -> we're just going to say date picker dialog dot on
date set listener date set listener is equal to
139.36 -> new date picker dialog on date set listener
hit enter to implement this override method
145.36 -> on date set and then we're just going to change
those in so they're actually year month and day
149.92 -> and then it's got a funny little thing where
the month is actually zero so January is zero
153.36 -> so we're just going to say month is equal to
month plus one so January is equal to one string
158.24 -> date is equal to make date string and then create
a new method called make date string which takes
163.68 -> three ins day month and year and then i'm just
going to return month with a bit of space plus day
168.4 -> with a little bit of space plus the year and we
could just leave it as is and you get an all-digit
172.48 -> date format but in my experience in software
development it's worth using this state format
176.64 -> with the string like so jan feb march because most
people around the world can read and understand
181.92 -> and are happy with this date format if you start
doing the digit one then you know some countries
186.08 -> will say oh no you put the month first and some
countries will say you know you put the day first
189.52 -> and i'm sure there's a country out there that
says no you should put the year first either way
193.2 -> if you use this date format generally speaking
people are pretty happy and then just returning
198.08 -> jan as a default the method shouldn't really
ever reach here though so you could probably
201.52 -> put in whatever you like cool so now we've got
our nicely formatted date string we're just going
205.6 -> to say datebutton.settext with our date and then
below that i'm just going to say calendar cal is
211.04 -> equal to calendar dot get instance and i'm going
to say into year is equal to cal dot get calendar
216.56 -> year and then copy and paste that down twice more
and get month and day so what we're doing here is
221.68 -> just getting today's date and we're going to use
today's date as our default selected date for our
226.4 -> date picker next we're going to declare one more
int calling it style and i'm going to say style
231.12 -> is equal to alert dialog dot theme holo light so
you could pretty much choose whatever style you
235.52 -> like here but i like to look at this one next date
picker dialog is equal to new date pick a dialogue
240.64 -> and giving a context of this given then giving
it our style our date set listener year month and
245.6 -> day now that we've initialized our date picker
dialogue we just need to go into our open date
249.2 -> picker method and just say datepickerdialog.show
and then finally we're just going to set the date
254.32 -> button to show today's date by default so i'm just
going to say date button dot set text is equal
260.32 -> to get today's date so just creating a new method
which returns a string and then i'm going to copy
264.64 -> what we did for getting today's date from the
calendar and then just giving it month is equal
269.44 -> to month plus one because of that funny little
month nuance and then set return make date string
275.28 -> with our day month and year cool and if we build
and run this now we've got a pretty basic pop-up
280.24 -> date picker so just selecting say December
15th and it's populated that in our date button
285.6 -> and then let's pick a future date so boxing day
December 26 2020. one other thing i will show you
291.92 -> if you want to set the maximum date so you can't
pick any dates into the future and date pick a
296 -> dialogue we're just going to call get date picker
and then set max date giving it system . current
301.307 -> time and build and run this once more you can see
our popup date picker you can't select any dates
306.32 -> into the future you could do the same thing for
min date so set min date so say you only wanted
310.24 -> to pick dates into the future and nothing behind
it's another nice way you can just change set max
314.56 -> date to set min date cool and that wraps up our
date picker tutorial in android studio using java
319.28 -> if you like the video give it a like otherwise
i will catch you guys in the next tutorial
338.32 -> you
