Android Studio Tutorial - Part 3 (2020 Edition)

In this Android Studio tutorial let's work with ConstraintLayout, but basic building block for building the UI for screens. This Inventory Management app needs to allow users to provide a product name, product owner and date purchased. We'll use a Button widget for the submit button and some EditText's for entering text.

An EditText is a special widget in Android Studio that will allow the user to provide a string (text). When the user taps the EditText on their phone Android will automatically focus the EditText then open the phone's keyboard for the user to type. The keyboard is just what you'd expect: a full keyboard, just like when entering text into any app like Snapchat, Facebook, Twitter or Gmail. Word suggestions even work.

ConstraintLayout can be complicated, but hopefully this tutorial will help. In this video we won't even touch the XML code behind ConstraintLayout but instead use the visual editor in Android Studio.

If you have any questions please leave comments and I'll try to respond! If this video worked for you and you have the time, can you try to help others in the comments? Thanks so much!

See you in the next video!

Note: We won't be dealing with Kotlin in this video, but are purely focused on the UI, which doesn't use Kotlin. We'll get back to Kotlin in a future tutorial.

Just LOVE that the videos get longer and longer even though you're trying to keep them shorter <3
Doesn't matter, you're great anyway!

Been using this tutorial to work on a simple calculation app for crafting my tabletop gaming group.

I'm adapting your lesson to what I'm building and in this lesson I also added a dropdown-menu/spinner to my add_product page. Took a bit of tutorial hopping and breaking down options to figure it out.

Good lesson and yeah, for the colors I realized setting them in the color reference script and having the visuals pull from that makes changes simple and easy as you get further into your design.

This could not have been timed better! At least I can do something productive during lockdown now.

I really don't mind how lengthy the tutorials are since I really like Daniel's style of teaching it's something that you can absorb but I just find it a bit funny, Daniel keeps apologizing for making the videos long in Part 2 and promises to keep it shorter and then comes Part 3 and I see it's even longer lol!

Dude this is really refreshing my memory. Thank you very much.

The KDE/QT GUI designer, they are "springs" thus the look of zigzag line. Looking forward to more of the backend info and such. Not that I'd use anything like that for anything personal but it should be easy and fast to push out for doing apps for others.

Daniel, you have no idea how far your tutorials reach, this comment salutes your tutorials all the way from Africa, Sudan. Truly appreciate it mate.

I've been searching youtube for a while now looking for a simplified tutorial where it would teaches how to use Room Relations and MVVM, in order to create a simple invoice app where you would create a new invoice and add products to it from product_table and see the product list updated whenever you add/remove a product, and when you hit Save, the data will be saved to invoice_table and invoice_product_table using Primary and Foreign key. Could you please make a video tutorial for Room Relation?

really usefull tutorial, can't wait till the welcoming screen or welcoming ui

[suddenly]

Daniel Thank you, man. could you please focus on code not the design

[MrJasonSnell]

I hope part 4 is making a list on the main page of our products, or I hope we get to that soon. Need to hook up that submit button.

[maherasultana]

Very informative. Please make more and make it beginner understandable just like this one

[joshlantry]

Hi Daniel I'm wondering if you can make a tutorial on how to make a music player app that can connect to bluetooth? Cheers

[peterfraga]

Hi Daniel,
This Inventory program are you planning on using a dBase and also maybe a way of showing the info in a Grid...
I hope so... I have added fields to the project to make it useful for me. I have added a Product Part Number, Product Name, Product Description, Qty.


I would like to know how I can get the key board not to come out when I am in the Product Part Number. I plan on using a barcode reader...
Then when go to the next Field which is Product Name the keyboard to show up.


thanks for you help... can't wait til #4.


I have a question about an app I am working on similar to this... can I write you some other channel or email you would like for me to use?
