How to Make Android Apps 7 : Android Spinners and Layouts

[@jean-francoispicart2396]

Hi Derek, I am used to looking at computing video tutorials on youtube quite intensively and I have to say that you are the best I"ve ever seen so far! This is first comment I have ever left and it had to be for you. How can someone produce so many top-quality tutorials at such a pace??? It is simply amazing! Please continue this excellent job!

[@derekbanas]

+Jean-François PICART Thank you for the very nice compliments :) I'm very happy that you like them.

[@salafzal4791]

Derek Banas I am very impressed by the quality of your tutorials. I also think they are one of the best tutorials on youtube. The way you zoom in and out in your video to draw attention to what your doing is really helpful especially when someone is speeding up the video. I can imagine that must be a lot of work, but please continue doing that as it is very helpful in drawing our attention to the important parts of the tutorial. Also, the fact that your videos explain a concept in its entirety is also extremely helpful to someone like me who knows a little bit about android dev and just needs to brush up on a few specific concepts. I discovered you through your content provider video, i loved your format so much that im watching this series from the beginning. Once again. Love your videos and appreciate all the hard work you put into them.

[@derekbanas]

***** Thank you very much for all of the wonderful compliments :) I do my best to make the best tutorials that I can. I'm glad you are enjoying them. I'll keep making Android tutorials until I have covered everything.

[@jakemalachowski4018]

Derek Banas Just out of curiosity, how much time do you spending working on each video on average?

[@DragonsTrap]

I'm watching these as soon as you make them; you've made this a convenient time to get into android coding. Thanks.

[@derekbanas]

You're very welcome :) The next one will be up tomorrow or the next day at the latest

[@moroccovideos2167]

Man, this stuff was hard enough already, and you just blasted it right through the roof!

[@dheerajasnani7918]

Best tutorials on android development without any doubt..thnx

[@derekbanas]

+Dheeraj Asnani Thank you very much :)

[@MrEmazek]

You are the best on KZbin for any programming language! :)

[@derekbanas]

MrEmazek Thank you :) I try to do my best.

[@derletsplayer9140]

Derek Banas Thats real!

[@juicebox187]

Thanks for the Settings -> Editor -> Auto Import, I have been looking for this feature for a while now. Great videos also!

[@derekbanas]

Thank you :)

[@Zofjap]

Great tutorial like always Derek. You never dissapoint me.

[@derekbanas]

Thank you :) It is nice of you to say that.

[@semirumutkurt6635]

the idea of showing what the app will like in the end is good and the idea of writing storyboard of the app is brilliant. that's how we learn to develop algorithms for the apps. Thanks in advance

[@derekbanas]

I'm happy you like it :)

[@MarcelKooiman83]

Only 2 minutes and i Subscribed, this is gone be helpful and easy to swallow!

[@derekbanas]

Thank you :) I hope it helps

[@MarcelKooiman83]

Just finished my first app! Your videos realy speeded up the progress. So like i predicted, helpful and easy to swallow. Now i have to focus on making the app look good. Its a simple work hours calculator, on my work they still use paper and pen.

[@t0nn0]

Great Work,Love how You present everything

[@derekbanas]

***** Thank you :) Many more videos are coming

[@pattmayne]

Do you cover custom-created views in any of your videos? I made a custom view and implemented it in an Activity (as if it were a button or whatever) but I can't seem to access the custom view's custom methods, or find answers about how! Thanks.

[@derekbanas]

Matt Payne I'll be spending a lot more time on interface design very soon

[@shmilos]

Derek ty for those amazing tutorials!! helpful as usual! :D

[@derekbanas]

Shmil Peretz You're very welcome :)

[@burnburn14]

Your a beast man. Quick side question. What do you use for Mobile App mockups? like to design what the app would look like? What software do you use or suggest?

[@derekbanas]

soyboy Thank you :) I normally design everything in Illustrator, but Inkscape works and it is free.

[@burnburn14]

THANKS!

[@siyarampal4884]

Most enjoying coder. Would like to know when did u started learning android what do u refer and tips for beginners.

[@derekbanas]

siyaram pal I started making Android apps in 2009. I have been programming for over 30 years now. I'm old :) I made a beginners tutorial kzbin.info/www/bejne/q5i6pmadrtmYaqs I think the most important thing is to have fun and to not rush the learning process. Exploring, making errors and creating ever increasingly more complicated apps is the most important thing. Also learn the basics of Java, UML, MVC and object oriented design and everything else will come easy. Take your time and have fun!

[@Ragusubedi]

Do you respond to messages written here? You are the first person whose video i watched first in March this year, and by now I know little.

[@adnFx2]

Simple actions its a good feature for these tutorials!. Wp! :D

[@Paul-qd7je]

hey derek, did you cover building a homescreen or a UI using android studio''s graphic interface cause it saves a lot of time when you are building your homescreen. if yes, which of the tutorial covers it

[@derekbanas]

News Box Yes I make a splash screen in this video kzbin.info/www/bejne/bnKnk2iYg7R5fqc

[@lasredchris]

Hi derek, sorry this is an unrelated question but for your stock videos, is there anywhere else to get xml data like that?(not just for stocks, but for sports, scores, news articles, etc)

[@derekbanas]

Sure you can parse pretty much any web page. Websites have different rules about how much you can display though. If the app isn't commercial I don't see any problems that may occur though

[@Ziado4]

What's the difference between a listView (w/ adapter) and a grid (nx1)? Isn't it the same? Thanks a lot!

[@05Bess]

Why do you initialize unitTypeSpinner in addListenerToUnitTypeSpinner() method if it has been already initialized in addItemsToUnitTypeSpinner() method?

[@ricotjeanlouis2656]

Hello...! Please I need help. I create a application there is a spinner and there are 5 items in the spinner when I select 1 item and click on save it save normally in the database. the problem is when I click on the button modify the item that I save on the database I don't see it...I see a other Item. Thanks.

[@lightmire7257]

very good tutorialss !!

[@derekbanas]

+light mire Thank you :)

[@surajmaurya3250]

I like your video which consume very less time good explanation

[@derekbanas]

Thank you very much :)

[@BuckstarrZ]

I've been wondering if the big nerd ranch guide was still a good buy, considering android 5ish coming soon. Books are so expensive that I wouldn't wanna regret it afterwards :-\ Do you have any suggestions maybe?

[@derekbanas]

I list it because I get asked all of the time. In my opinion the goal from a book is to learn the basics. Then you can learn everything else online easily. Sadly most Android books for some reason are loaded with coding errors and bad practices. The only other book that I'd recommend is the Murach book, but I think it is not as good as the Big Nerd book. Just my opinion.

[@BuckstarrZ]

Alright, thank you! Guess I'll give it a try then.

[@derekbanas]

I always get e books because they are so cheap, or I buy used.

[@BuckstarrZ]

On which I would agree if it were a novel or something, for technical textbooks I find it usually easier to get around with actual pages. There is almost no difference in price whatsoever in Germany at least. Thanks for your thoughts, highly appreciated. First playstore app coming up soon(ish) thanks to you!

[@zulumopuku5370]

will the updated new version be series based or Learn in one video ?

[@derekbanas]

It will be series based. In each video I'll make a complete app, but I plan on making many apps and videos.

[@zulumopuku5370]

@@derekbanas still long until u will start releasing them ? I am learning it now, and your videos will help for sure. Would this actual version also do ?

[@MrHomeu98]

Dreke, here are the list of the problem that i'm currently have 1: i'm trying to make a custom dialog boxes to pop up when the game is finish, which contain two buttons and some data. 2: the XML, is not changing size accordingly to different devices, is there a way where i can set those size to % so no matter what devices i'm using it, it will just resize it to it. THank you so much

[@MrHomeu98]

and also progress bar~

[@derekbanas]

I'll cover dialogs as soon as possible. I think after the next video I'll cover fragments because many people struggle with them. It will be up this week.

[@MrHomeu98]

thank you~

[@ARFallaha]

Mr. Derek Banas For some reason, when I click on "Sync Now" after editing the gradle file, the Java files stop recognizing the R (R.id.etc) What should I do?

[@derekbanas]

Abdul Razzak Fallaha Delete any imports with R. in them. Rebuild, Clean and it should be fixed. You may have an error in one of your layout files. Make sure your layout files only have lowercase letters in their name.

[@pdaae]

Hey Derek! In one of your previous tutorials you recommended to testdrive apps on a "real" android device. I've scummed through the developer pages and made some tries, but i still dont make it :/ Would be pleased if you made a tutorial on how to do this :) Best regards :P

[@TrivediKavit]

What Screen Recorder software you use ?

[@derekbanas]

Here is the screen capture software I use goo.gl/aAbqE1

[@BelieveInPeople121]

is this still good to learn from or is it too old and a lot of new things came up after 2014?

[@derekbanas]

Yes the basics of developing for Android are the same. The interface looks different

[@shaskies]

Omg Derek! I've set an emulator Nexus 2012 that takes 10 minutes to load. Once it loads up I get a blank blue background screen with clouds and the time in the top left corner of the screen. And then it goes grey with "no events" message displaying. It's not working. Do you have a clue as to what is going on and how I can fix this please?? I tried using my android device but unfortunately I can't find a driver online.

[@lasredchris]

Whats your device?

[@shaskies]

Chris Sun My phone: HUAWEI Y320-U151 Android version: 4.2.2 Emulator setup: Nexus 7 Target Name: 4.4W CPU/ABI: Android Wear Intel Atom (x86) API Level: 20 Android Studio beta 8.0 (Since I didn't know what this stuff means, I thought it might lead to a fix)

[@lasredchris]

shaskies consumer.huawei.com/us/support/index.htm go to live chat. They should know

[@derekbanas]

Use the emulator set at version 19 of Android. That gets rid of that. I have a link to how to do that in the description

[@shaskies]

Is the Link in this video's description? Because its not there

[@redredornblack]

1)why are you using charSequence in array adapter instead of string. any particular reason? 2) Instead of doing so much burden in creating arrayadapter, why can't we simply create normal arrayAdapter with normal string array. is it possible?

[@zarzyk_1990]

You probably know this, but I don't see any reason why you didn't use the quick fix on the non-existing method. It's just alt+insert and "create method". Anyway, great tutorial, can't wait for the next part.

[@derekbanas]

Yes I try not to use to many short cuts because of how they are different on some OSs. Thanks for pointing that out though :)

[@surajmaurya3250]

I like your video's

[@janneniemensivu475]

I really like this series. However, zooming really makes following these videos quite difficult.

[@derekbanas]

+Janne Niemensivu Sorry about the zooming. I do that so people can see everything on their phone. I have stopped recently

[@alaslipknot]

Thank you !!!

[@derekbanas]

You're very welcome :) I'll try to get the next part up in the next 2 days.

[@freddieb91]

hello derek different subject i need help with your coda slider can i email you?

[@derekbanas]

It is better to ask the question here. I get about 2,000 emails a day and most that I don't know go in my junk folder.

[@freddieb91]

ok i wanna send you a screen shot of whats happening all my panels are gone and scrolling bars have shown up on safari but everythg is fine in google chrome

[@geekinginandout]

where do i donate?

[@derekbanas]

Edsel Malasig Thank you for asking, but there is no reason to donate. I'm satisfied that I'm able to help :)

[@KyleAisho]

Edsel Malasig I just choose not to skip Derek's ads, every little bit helps :)

[@psmith5573]

I keep clicking on every single ads I see on his tut video. lol hope it helps.

[@ivandidymoi]

checkIfConvertingFromTsp(itemSelectedInSpinner); checkIfConvertingFromTsp is red pls help!

[@DiannaFerris]

Derek Banas It was actually sent through Google+ and relates to these posts. Let me know if you need something else, I'm still learning all these tools. :)

[@derekbanas]

Please send me the note again. I get so many messages and I don't seem to get them all. Sorry about that.

[@smarttech_hub]

nice one boss tnx

[@derekbanas]

+vincent ochigbo Thank you :)

[@danielb1194]

One question: why do you use charSequence on the array adapter? is that the way XML files handle String arrays?

[@michaelaubry1338]

@android:style/TextAppearance.Large is what worked for me.

[@nelsonyiap81]

If anyone's TextViews inside the GridView are not filling up the available space, add android:layout_columnWeight="1" to all of your TextViews :)

[@derekbanas]

Thank you for helping :)

[@DiannaFerris]

btw Derek Banas I have a unique opportunity coming up, if you have any questions that you would like to ask about android wear, I'm having lunch this Friday with the Google folks that are working on it. Just let me know.

[@derekbanas]

That's very cool! I wouldn't know what to ask. I have never had my hands on any of that hardware. If something comes out with a great heart rate monitor I'd get it since I ride my bicycle constantly.

[@spanky1093]

yes modularizing the sht out of everything is good.

[@dezmacht1]

"...couple hundred Android applications" omg haha

[@hamidrezagholami9467]

[@surajmaurya3250]

good

[@derekbanas]

Thank you :)

[@surajmaurya3250]

thanks

[@pommoysel]

I really like your tutrials, but there's Point which I have to criticize. You do too much off the zooming into the sourcecode, for example if want to see a certain part of the code I always have to search for a moment where the zoom is right. I mean one can download the sourcegood, but it feels more comfortable if you can see the whole code at the same time. Your Videos have HD quality so I see no reason for the zooming. And in comparison to your old videos it is getting worse and worse ;). BUT THANK YOU FOR VIDEOS

[@derekbanas]

pommoysel Sorry about the zooming. Some times I obsess about people not being able to see the source code on mobile devices. I'm trying to find the best way to solve that problem on every size device. Thanks for the input.

[@icekoldkiller2]

Sir, it would be really nice if you created repositories on github with TODOs for us to do as exercises. We could simply follow all the TODOs and be confident before we proceed further.

[@surajmaurya3250]

I like your video which consume very less time good explanation

[@surajmaurya3250]

I like your video's
