DavidTheGeek:

ASAP.

This tutorial class, though we just started, has started rubbing off on my time & pocket. So i've decided to conclude the tutorial i started here, take a break, do some planning, (thereby giving space for new interested Nairalanders to join and catch up) & proceed in another way.

Dave please how do we send some data across. ....cos this thing, there's no going back o (we must learn it)

folks4luv:

corrected now. the prob was that I didn't modify d \> and >. guess we need to learn what those symbols mean. .
thanks op. now I can go to bed

Good.

/> is a closing tag.
< is an opening tag.
> i'll call this tag "suspension tag"

For better understanding i'll give examples.
<TextView ....... this means you've started writing codes for textview.

When you open a fridge to take water, you should close it when done abi no be so? That's what /> does. It means you've finished writing the code for TextView.

> is used on a Parent to close and accomodate its children. A viewgroup is a parent, while view objects are its children. Example...

<LinearLayout ...... i'm done writing the codes inside here. Close me>
Add children here.
</LinearLayout>

Ok...about the background and color codes, are they generated randomly or there are specific codes. like if I want the color something else other than red,?

You can restrict it to once or twice a day. Thank you once again.

DavidTheGeek:
Before we continue, i'm thinking we should move this thread to a Whatsapp group. It'll be much easier to post and view screenshots (and maybe videos). Also i'll be giving you guys assignment once we get to real work.

What do you guys think?

Please add me if you want to migrate on 08137066183

Am in too

There's no difference in the programming code for new aide, old aide, android studio (for pc), it's all the same android programming code.

Follow the instructions.

eyaaa sorry ....no mind those mods e ya. we are solidly behind u......lolss

The second method of creating string. i.e using strings.xml is a better practice as it allows for cleaner coding and easy text replacement whenever you want to replace, it is also good when you want your app in anotherllanguage as you can easily just translate everything in ur strings.xml to the new language while maintaining the names of each string.

Imagine walking to a class with 10 boys and 10 girls, the only way to differentiate them is by their names..
That's where ID's come in

Every element in android has a id that uniquely identifies it so that you can do various stuff with it.

You can have 2 buttons of similar desig, its their IDs tthat you'll use to differentiate them and use them to call different actions. Eg a yes button and a no button

There's a way in aide where you can click on a item in the xml and it woukd show you all the available attributes that you can work with for that particular element eg button, editText, textView, imageView etc

On the design view you should also be able to move elements around and when you do so you should see an addition line of code that would signify how you positioned it so that you could also learn how to do it by code

First App. DavidTheGeek, here is it.
