Android RecyclerView Step By Step Tutorial (Part 2) Introduction - 2016

Let's continue our lesson in android studio.

We talked about the androids RecyclerView.

This is part 2.

This is my YouTube channel as usual.

You can find me over there and please supportme by liking my Facebook kosal geek and also follow me on Twitter and I have github aswell.

I talked about this already.

And the step that I have done is, this oneand this one.

Just four and seven.

So we still have one, two, three, five andsix.

This is my YouTube channel.

Please watch me here.

Or maybe just write my name like that.

It�s fine.

Don�t forget to subscribe and this is mypage.

I made it this way that you want to watchit in English, so please share and like or just like what you want, to support me andI feel happy.

If you don't support me, I feel sad.

This is what we have done.

We just created the CardView and ListView.

So, we need this, number two and number threein the data.

Here, you want to create a class.

Right click and choose new, Java class.

Call it item.

You should implement Serializable becauselater you will use it to transfer from one activity to another.

So, it�s a good Let's continue our lesson in android studio.

We just createdthe CardView and ListView.

So, we need this, number two and number three in the data.

Here,you want to create a class.

Right click and choose new, Java class.

Call it item.

Youshould implement Serializable because later you will use it to transfer from one activityto another.

So, it�s a good practice that you always implement Serializable in androidand I�m not talking about Java.

What I'm talking about is what class you should implementSerializable for that.

This one is the ID types and image.

Usuallyin Java, when you want greater feel, you set a time heads up like that and then you havepublic void and you set ID to here.

This ID and get ID and return this ID.

It just took a call, set time to get in ID but this one particularly,I'm not using this kind of sign because later on, your used disk data, this class matchto the data I get from JSON and I used one of my library in the github, and the libraryuse another library from GSON and GSON doesn't want you to use this kind of style.

It wantsyou to use something like this.

Probably, int ID.

You don't need to create a set andgo for it.

Just use public against the Java file button.

It's fine.

GSON likes this stylebetter.

What else, image and img as the URL for image.

So, now you have the class items and numbertwo.

Now, you need data number one.

Just like I said, we need the real data but don't haveto live with it.

We just want to show something and later on, we will use the real data.

Butnow, maybe just create a method.

Private.

I want to create a bunch of ArrayList.

I declareit as the ArrayList like that.

The class here is the item, we just created a list of item.

We just generate Dummy and nothing now.

Maybe for, I want it to run from zero to maybe 50.

I plus, plus.

So, we're going to create an item.

This isa big I and this is a small I.

New item.

So, Item ID or I because it's an integer.

Andtext.

Dummy text.

I want to add I to make it different.

And image.

That is a trickyone.

You want to have the image.

So, now, there are two ways.

One, you can use thisimage but to get an image from here, you use simple but later on, we will not use imageinside your application.

You can store like, one thousand images.

You're going to makeyour application too and just only images.

So, instead, you just get it from your internet.

So, it's better just to collect that.

Waterfallin Cambodia.

Cambodia is my country, if you don't know that.

You can come and visit.

Wehave Angkor Wat.

Maybe if you don't know this, you know this.

This is my country.

Copy imageaddress.

You can see that the URL has something after the image.

So, I dno't want that.

Now,that's good.

Copy.

Now, you have this.

Then, you need to add two ArrayList but internalones.

Just call this new ArrayList.

For Java seven, you use this.

But there is Java eight,you don't have to use them a chance to clear from the left.

Then, you need to add to list.

After you run 50 times, you just return itto my phone.

I want to make the data more interesting.

Just one image, it's not goingto be fun.

I want to create a difference, so, if I modular two, three to zero like threesix.

Then you want to have different data.

And else if for a different data, I modulusseven and then I have a different data.

Then, 11, prime number and then maybe the rest.

So, this one is going to be ankle.

But maybesome other image.

Bayon Cambodia.

Another temple, popular temple.

You have to wait untilthe logging finish.

You paste but you cannot fire because Google is trying to protect you.

Just like that.

So, the second one.

And maybe Angkor Wat.

But the number is going to bedifferent here.

One more, Maybe two more.

Something text.

Last one, this one is a moderncity or whatever.

Loading.

Looks good, right? It's not bad.

Now, you add it.

Copy to eachone that it can do.

Now, we get a data.

We're going to process it into right here.

Justget the data correctly.

Now, we can use the step frame.

Egg one, two,three.

Now, this is the big, big thing.

You need to have the layout manager.

This oneis easy.

This one is the RecyclerView.

Actually, we don't need that.

Just for example, in thelast video.

Just need the RecyclerView.

Let's go back to the lesson.

Android RecyclerView.

It's a very good lesson here.

You don't have to read another block.

It's going to be good.

If you want to know more, I recommend this.

This one, this layout manager is very easyafter you get from the layout and he said, if you have a big size, then you use thattrue.

To improve the performance.

So, let's do it.

Rvitem, set has fixed size.

I callmanager, new LinearLayoutManager and this.

We use here the linear layout but actuallywe can use another like greed.

We can use it.

It is one of the very simple one.

I will talk about the Layout in the next video.

But now, it's done.

So, we didn't set the layout yet.

Set LayoutManager.

And this one,we going to use it for the adapter because it is very complex.

I want to make anothervideo.

A special for that.

That's all.

This is what we do.

You need the item, class.

Don'tforget to use Serializable.

This data, just for example, we just created a dummy data.

In the future, we will use the real one.

Manager, 3.

That's all and I will see you in the nextvideo to talk about the adapter.

Thank you!.
