13:43
main doxml this is the file right we design right now here this is a design view this is a text right now I just
13:50
click on the text right here text it's easily designed with the code right now here what I'm going to do is here I'm

19:56
the code if I fill this form click add button record goes and added into the database SQL database right so what I'm
20:03
going to do is here go to the main activity Java right this is the file where we hope right so this file you can
20:11
find it here as well go to the Java folder inside the Java folder uh this is the package inside the package there
20:17
there will be the file main activity right main activity file what I'm going to do is here here uh here after that

37:30
you have to like this simple you have to write here PST six
37:37
string one comma this one should be I see C
37:43
copy paste after that this C copy paste right second one should be
37:51

paste here this one two this one three finally you have to after add the record
39:01
it focus on that because I will focus request focus method that call request focus method
39:06
like okay let's check whether it's working fine or not right I have virtual device I have used the J
39:14
gen motion you have to connect anything else I have using in your gen motion right this is the virtual app I'm going
39:19
to use for uh doing the stuff now what I'm going to say now here what I'm going
39:25
to say we have to check everything is correct here we have return finally we
39:30
have to return this connection this
39:36
connection connection is connection now the error is go away this
39:44
is the thing we have to worry okay now what I'm going to say this add method control C copy you paste inside here
39:52
when the button is clicked which added the records into the database right now now there is no error now I now here
39:57
what I'm going to do is we have to check here whether the code is correct or not uh uh here the IP error DB we have to
40:06
specify the database name here we have to write here uh data base
40:13
name plus name right we have write like this okay perfect equal database equal
40:19
to name equal right this thing we have to write perfect right now what I'm
40:25
going to see everything fine now I'm going to go to the manifest file manifest file we have to add the
40:33
internet uh user permission for the internet right so here I already done the stuff here the manifest file here
40:40
this same permission you have to add here C to copy control V to paste it here right you have to type like this

it's very simple you have to get the network permission from here you have to choose right that's how you have to add
41:16
the permission right okay I have already added here the same thing you have to add right this I think very important
41:22
stuff right you have to add this permission these two permission into the Android manifest doxml file then only it
41:28
should work right okay now let's check whether it's working fine or not uh everything Perfect what now let's
41:37
check what okay now let's click start
41:42
gen motion this app genotation now I'm going to start the
41:49
app right perfect right now here it's coming here now I'm going to add the student ID
41:57
3 host name I'm going to write as PHP see I'm going to enter as
42:05
20,000 click add button success right it's working fine right now let's check
42:11
go to the database registration table fine so it's working fine great
42:18
it's a PHP success it's working fine right very simple one you have try
42:24
yourself right while you're getting any problem you can ask me anytime uh now after that what I'm going to do do is
42:30
here I'm going to view this record in in the list view in my next tutorial I'll be explained uh how to view this after
42:38
add the records you will be able to view the records in the list view in my next tutorial I'll be explained thank you for
42:44
watching if you like my channel please subscribe me like me thank you for
42:50
watching hi guys welcome to tutori channel in our last class we saw how to
42:55
add the records into the SQL database in this class I'm going to teach how to how
43:01
to view the data from the database and how to edit the data as well as how to
43:07
delete the data right let's go to the lessons right here
43:14
uh this is the design bar now what I'm going to do is here I'm going to create another
43:22
activity right i'm going to create another activity here so that go to the apps folder right click
43:30
new activity here I'm going to create as a
43:35
uh empty activity right here we have to click finish this one we have to select as
43:43
view this one should be view right click finish
43:52
now your view activity has been created successfully this is the Java file and here this one should be the layout of
43:57
the view activity right now here what I'm going to do is here I'm going to view the data right here so view the
44:05
data i'm going to here go to the pallet of the Android Studio here search here is list view i'm going to view the data
44:12
from the list view right if you type LI here this one should be the list view here just drag and drop
44:21
here right it's coming look like this now here what I'm going to go to the go here same thing you have to change this
44:28
one as a earier we did it in a record insert part we have to change
44:34
the layout as a linear layout the same thing you have to change here as a linear layout and the and you have
44:40
change here as as as a orientation vertical vertical right okay this is the
44:48
you have to do right same thing you have to do after that what I'm going to do see we have to write here is a
44:54
uh same thing you have to do here is
45:00
uh orientation you have to type here is ID
45:07
right here is list one I give the ID like this
45:13
that's the thing I have to we have to do this is the things right that's the thing you have to do this is look like
45:18
of a of a list view right simple list view look like this right you can check
45:23
right here likewise right now what I'm going to do is here
45:29
uh I'm going to go to the uh java right view java file here so
45:36
here we have to first what I'm going to do is here we have to type here list
45:42
view I'll type list view this one list you create a
45:49
li one right perfect after that what I'm going to assume we have to write here is
45:54
simply you have to write array list you have to write after that array
46:00
list array
46:06
list you have write here is
46:11
spring write titles equal
46:18
New array list control C to copy control V to paste here you have to write this one
46:28
string after that this one right perfect after that what I'm going to do array
46:40
adapter array adapter you have to write like this perfect after that what I'm going to do is here we have to write
46:46
here is you have to list one this one I create the the
46:52
variable above I have to find it this one we have to equal into find view by
46:58
id r dot id dot list one this one we have to take it
47:06
okay list one mean this one where is the name list one okay here
47:11
I have added into the code here list one ID Android ID so you get it here after
47:16
that what I'm going to do is here uh we have to the same code go to the uh this
47:23
one main activity main dot here this one insert code we have written right the all the connection and every stuff we
47:29
have to copy from here right instead of u adding the uh from the beginning so
47:34
you have to get the copy of this one right you have to get a copy
47:39
uh here until the this one you have to get all the stuff try catch all the stuff you have to get the copy
47:46
Perfect i think you have to get the copy of that one right after that what I'm going to do is here to copy control C
47:55
copy this one we have to go to the here view inside here you have to paste
48:00
control B to paste here right all the classes should be added no problem here successfully right okay right now the
48:08
same thing this one should be our database name this is your username and
48:14
user name uh user credential of uh SQL server this is the uh strict mode right
48:23
okay here all the stuff are same database connected also here what I'm going to be no need this stuff here I'm
48:30
not going to add the data so here what I'm going to do is here we have to remove them this one we no needed here
48:37
after we have to do the quotes right now here what I'm going to do is here we have to create the statement class so
48:47
statement statement here statement ment is tmt equal
48:53
uh connection object dot create statement after that what I'm going to
48:58
write result set result set uh rs
49:05
equal st empty st dot you have to write execute
49:14
query you have to write execute query here we have to write the select statement
49:21
Select all from what is the table name table name
49:29
is registration reg we have to view the data from the registration table after
49:36
that what I'm going to see this title array list array list titles title
49:44
titles price so you get it here ctrl C to copy Ctrl + V to get it here first
49:50
you have to clear the one array you have to clear the one after
49:56
that what I'm going to do is here we have to write two times short right after that what I'm going to do here you
50:02
have to write simply uh write a final keyword
50:08
final array
50:14
list array list right now here what I'm going to say I'm going to create this class right you have separate class I'm
50:21
going to create here right click select the inside the Java folder there will be
50:26
the package com uh example uh course app right click here I'm going to create the
50:31
Java class separate Java class I'm going to create here you have to name it as course you have to name the class name
50:36
as course click okay right here I have to create relevant properties so you
50:43
have to write string ID this is a course ID come after
50:48
that you have to write Then second one string co name
50:54
co simple write co right after that you have to write another thing is a string
50:59
c right this a simple word we have created on the this class right after
51:04
that what I'm going to say go here you have to write array list you have to write here array list you have write
51:10
here is co this this class we have to get it here write separate very simple
51:16
one after that we have write the list equal
51:22
new this one array list course to copy control V to paste here this is the
51:28
thing we have to do okay after that what I'm going to do is while we have write the while loop
51:36
this result set RS dot
51:41
next you have to write here is
51:47
course you have to create the object equal new
51:55
course after that what I'm going to say is object we have to call it here object dot
52:01
id equal rs dot get
52:08
string we write here is first one should be the id first one should be this ID c ID E
52:15
after the C name C this is coming from the database right it's loading all the details we are passing here right RS dot
52:22
it is here I call it RS we are passing here this is coming from the this ID is coming from this class right here it is
52:30
display and assign to this variable right okay out of the same thing C copy
52:36
control V to paste here right second one should be the simply get it at a course
52:43
right this one should be the Suppose here we have to change the name as uh C name C

53:20
add OB this one we have to add ctrl C copy control V to paste here
53:27
plus here to write as a this one should be the tab key of of Java tab key right
53:33
T mean tab right after that plus we have the second one should be we have to show on the uh
53:40
ID plus course after that plus we have to
53:48
equality tap key after that we show here as OBJ dot C that's it That's the thing
