FAQs on RecyclerView in Fragment in Android Studio Tutorial Video Lecture - How to Design UI in Android Studio
| 1. What is a RecyclerView in Android Studio? |  |
Ans. A RecyclerView is a powerful and flexible view for presenting large sets of data in Android applications. It is an improved version of ListView and GridView, and it is used to efficiently display and manage large data sets in a more customizable way.
| 2. How do I add a RecyclerView in a Fragment in Android Studio? | |
Ans. To add a RecyclerView in a Fragment in Android Studio, you need to follow these steps:
1. Add the RecyclerView dependency to your app's build.gradle file.
2. Create a layout file for the fragment that contains the RecyclerView.
3. In the Fragment class, initialize the RecyclerView and set its layout manager and adapter.
4. Implement the RecyclerView.Adapter to bind data to the RecyclerView items.
5. Finally, set the RecyclerView adapter to the RecyclerView in the Fragment.
| 3. What is the purpose of the RecyclerView.Adapter in Android? | |
Ans. The RecyclerView.Adapter is responsible for binding data to the individual items in the RecyclerView. It acts as a bridge between the data source and the RecyclerView, allowing you to customize the appearance and behavior of each item. By implementing the RecyclerView.Adapter, you can define how the data should be displayed and handle user interactions with the items.
| 4. How can I handle item click events in a RecyclerView Fragment? | |
Ans. To handle item click events in a RecyclerView Fragment, you can follow these steps:
1. Implement the RecyclerViewAdapter.ItemClickListener interface in your Fragment.
2. Create an instance of the ItemClickListener in the RecyclerViewAdapter.
3. In the ViewHolder class of the RecyclerViewAdapter, set an OnClickListener to the itemView.
4. Inside the OnClickListener, call the onItemClick method of the ItemClickListener with the clicked item position.
5. In the Fragment, override the onItemClick method and handle the click event as per your requirement.
| 5. How do I customize the layout of each item in a RecyclerView Fragment? | |
Ans. You can customize the layout of each item in a RecyclerView Fragment by creating a separate layout file for the item. In the RecyclerViewAdapter's onCreateViewHolder method, you can inflate the item layout and return a ViewHolder that holds the inflated layout. Inside the ViewHolder class, you can access the individual views of the item layout using findViewById and customize them programmatically. By modifying the item layout, you can change the appearance and behavior of each item in the RecyclerView.

hey everyone this is anger escape from
Indonesia and welcome back to my video
in this video we are going to learn
about the reticle fuel and fragment in
the under studio so basically if you
have the another datas their profits in
the another class you can use it by
using the refactor and then we can
implement the data into the another page
with the recycle fuel and fragments ok
so right here I am going to create new
project which is free anger and next we
are going to use the API 16 which is
Android 4.1 and next we're going to use
the empty activity next and finish ok
while waiting for Gradle boot
I have prepared three pictures different
which is picture one two and three that
you can use it for the sample data in
the undress to do so you can prepare
your own pictures because I already
prepare it
alright so it's the Gradle build and
with it waiting for the minutes okay in
the firstly I want to copy my drawable
which is the pictures into the drawable
so we copy these pictures and go to
areas and drawable campus so you can see
I already have the picture one two and
three and then we close the main
activity and we're going to the main
activity underscore mine XML and then we
are using the framer sorry we are using
the fragment so we need to change our
layer to the frame layer here you can
change to the frame layer
all right and just make sure that the
heck it's mixed pattern and the width is
much better
so for caveny just let it go so we're
going to close it and then we need to
create new class which is Prophets our
data so we create new G focus and here
we can use it maybe our data okay and
here we got to create the rice so I'm
going to use the public because the data
is static so here maybe Tito and new
string and we got a to create and all
right here okay the alright number zero
maybe we can use a pendulum and here's
Shama
and here you can use a because we only
have three pictures so the string should
be three pictures sorry three items
which is zero one and two
all right we're going next to setting
our images so image is basically by
using the integer because we need to
take the replication from the drawable
so this is picture prepped and your
energy
and here we see a knowable picture
number one and drawable picture number
two and the last one which is the number
three alright so we already have our
data so we can use it later in our
project and just close the our data and
we move to the layout we need to create
new layout which is fragment list so
we're gonna click like no and layout and
you can give the name which is fragment
yes with dot XML because it's
automatically to generate a new file
with the extension which is XML okay and
we're going to the text and here I want
to make it different so we go to
fragment lists we need to create the
tricycle because we are using the rest
of you which is master pattern and this
is max pattern and we need to add the
another property which is ideal because
we want to replace it by using the ID so
this is Luis reticle sorry by using the
are few alright we're gonna to remove
this because we don't need just closing
tag with the slash like this and I want
to make sure our activity is already
have the idea so here we need to create
the ID which is placeholder because this
is the main activity that we can change
for the another pages from the fragment
or from the another pitch step we will
create later so this is the simple from
the fragment list but and and also that
is working so it's different
oh and forgot something
let's delete this we need to load our
library in the griddle and with Gradle
and we need to let me here I have
prepared the library so you just need to
copy my source code
this is library you can see we are using
the recycle fuel with number seven so we
need to since again alright
we already include our new library here
so that's to try again here basic ok we
are decent is much better and much
better and by using the ID oops here ID
please
see Co few and we don't need this just
remove and it's done alright so right
now we are going to create the another
XML which is profit for the layer so
this is the manlihood so we're going to
lay out and create new film which is
undo it and this item and this is we we
will use it for the manual but I think I
have problem here so we need to close
and delay because we need to click in
the layout directory is not in the
failure so we start again this item and
here we go we are wishing the Rinella
and just make sure that your lanyard is
horizontal because we want to make the
picture in the left and behind of the
picture we will have the another of text
and another link so we make it to
horizontal and here we will apply
the images Phil which is the weight its
0dp because we prefer to use the way so
and a hag 50 DP and we need to create
the Scout type which is the food center
and imagine yeah we need to margin which
is 8 DP and why it's 1 and we need to ID
because we will use this ID into our
java class this is adam image co and
behind of the images field we will have
the textview so the text field for the
weight it's 0 DP and heck it's Wahpeton
and we want to check another here which
is ID item text and we need to text you
know text and the text size is 20 SP and
the way is 3 and we need to set into
Maggie's 20 DP alright so as you can see
in the left we already have the images
and here we want to click the text ok
and here as you can see when the layout
is 4 which is Matt's parent so we are
going to the linear load and change it
to the rock Contin so when you hover
this the layout it's B it's being small
so you can duplicate this content and
limit its really I don't know so after
that we need to go to our Java okay so I
think it's enough for the XML so we need
to continue in the logical thinking
because we want to repeat and we want to
note our data from the Java to the
another
Chifa t alright we don't need this XML
so we just need to close to make it more
clear so we're going to jump out and
click new Java class which is the list
fragment okay and in the list fragment
we want to extend because we are using
the fragment isn't it
so here and here you will get to option
which is Android app or Android support
app so we are using the APA which is the
16 so we prefer like to use the Android
app because if we are using the Android
the support fee for app this is for the
APA below of the elephant okay so here
don't run to select this and we're going
to create few on crits I'm sorry
we need to define the variable first
okay just few
here you need to import the few and
unclear few layout in Fletcher and in
factor doable and then we can use few
group and container
and serve instance okay
and we need to import the bundle here
alright so here we need to create the
method which is fuel and we want to
replace the Laird activity from the
fragment so we need to Fletcher and in
fact by earlier and this is the fragment
list
container Falls all right and we are
using the reticle fuel find by ID ID
please vesicle phew okay when you open
the when it opened of frequent list you
will see we have we already have the
list critical field and here we include
the list vesicle fuel and after that we
need to create adapter know this adapter
okay
and here we automatically allow the
widget which is miss updater but
actually we don't yet because we will
create our our list abductor so we just
need to remove this input and if this
red color just leave it for the moment
so we need to finish the reticle filters
and here sorry we have seen the variable
all right
okay so you can see we have the red line
here but it's okay no problem
so right now we just need to create new
Java but what I want to return our fuel
we already create new variable which is
fuel and here we need to return our
value the frequent okay we are going to
Java to creat new another Java which is
the list updater okay and here this is
for the logical thinking yeah just
extend the recycle adapter okay
and you can select the reticle few and
ow
and enter and you will get implement
methods so just okay it's automatically
so you don't need wet by yourself okay
before we go to these methods we need to
create a new class which is this few
holder so here preferred class please
fill holder and externals the reticle
few holder and implements to the few on
click this turn okay and here we need to
define our variable first which is the
will going back to the list item as you
can see we have the ID which is item
image and item tag so we need to define
this ID prefix texts you and texts few
preferred images few and sorry item
image and here should be M item text all
right so we need to import the text view
and image view and after that I want to
create new method which is please fill
order few item field and here
so we already create new favorable mm
text field and I am a to me mix so we
need to define here again which we can
starting from the M it in text so text
few little few and we're looking for the
ID the ID is a total text ok code and
here we just need rip it but the last
steps which is images view and Ethel few
okay and the last one is setting the set
one click which is this cool and right
now we want to replace the fellows
it's the values of its this item and
this images so here we need to create
new another method which is been few
it's been been it's called the bit
bending so the data will replace by a
new data from our data here which is
panda in sumo and agua and this is
picture one two and three being filled
with the integer because the data start
from the array so we don't have to just
set text and we'll use it for the our
data and tittles
and position so this is the function to
replace the new value from our Java here
and secondly is item set images resource
sorry and our data and picture path and
position okay cool
the last one we need to create the new
method which is public for you on click
few few but the properties just leave it
we don't need ok so right now we need to
do two here to check everything is ok so
here the red line is gone because we
already create new Java which is list
adapter so you don't need to worry again
ok we take a lot for the main activity
we need to retain the little bit of cuts
but it's ok we can start from the list
fragment and a fragment a new please
peckmon
and fragment manager is fragment manager
and get the fragment manager sorry we
are using the transaction to to change
the data
and fragment transaction we add the
layout Beijing our LED and the layout we
can check to the activity and the ID is
placeholder so you can copy and go back
to main activity and press like this and
don't forget to the second parameter is
fragment because we are using the
fragment we need to commit okay I think
it's already done so we're going to
check it first into our cumulative so
here I will use the emulator which is
Nexus 4 with the APA is 26 so as you can
see we don't have any other but the data
doesn't so because we are forget Lala
it's my plan it's my bed I'm sorry I
forget to solve our data in the list
adapter so let's do that
oh my god okay so the first one is we
need to create new inflator here Beijing
the fuel and layered inflator
from so this is by using the pattern
dead context and in flat to the air
layout and from the list item and this
is the pattern okay sorry
we need to remove this because we don't
need double parent is parent and false
okay and we need to return no please
few holder few so from this we pick it
the data from the list item and we
return the list folder by the parameter
which is few the data Swiss item and
this field holder is from here okay so
it's all of them it's connecting and the
second one it's for the ambien few
holder so we use the two parent is
and please fill holder I'm sorry okay
and here we need to holder and beam few
and position so here for the gift item
cool so we're gonna to play tune our
data
Tito Lang okay I think it's done so
let's check it first again we're gonna
to run our application to the emulator
alright it's successfully critical isn't
it so the data start from the panda in
Xiamen hoga so we can take a look for
the data here so whenever you change
this the data is automatically change so
we got to add maybe you can add new data
here the most pre oh and here don't
forget to create new role able you can
use it for the picture one and we can
run this application again and let's see
what things alright so we already have
data which is demas prio and the images
is same with the pendulum because I'm
using the drawable picture underscore
one so basically this is how the
fragment and recycle feel working
together and this is pretty cool and I
want to learn again about this fragment
maybe in the next time I can create new
video about the another fragment method
so you can stay stone in my channel and
subscribe my youtube channel
okay I think it's enough and please let
me know if you have errors so I can help
you and then don't forget to subscribe
my youtube channel and gareki so nice to
meet you from indonesia and bye bye
hey everyone this is anger escape from

want to learn again about this fragment
maybe in the next time I can create new
