00:00:04,120 --> 00:00:09,650
G'day everyone. Welcome back. Our Settings
Dialog will extend the appCompatDialog

2
00:00:09,650 --> 00:00:13,550
Fragment class. Create a new Kotlin class
called

3
00:00:13,550 --> 00:00:31,700
SettingsDialog, and choose class before
hitting OK. I'll add the usual log tag

4
00:00:31,700 --> 00:00:36,910
and extend the appCompatDialogFragment class.

5
00:00:48,440 --> 00:00:53,340
The first step is to inflate our layout
in the onCreateView function.

6
00:00:53,340 --> 00:00:58,980
I'll get Android studio to generate the
stub, then inflate our layout. I'll also log the

7
00:00:58,980 --> 00:01:01,910
function being called.

8
00:01:23,260 --> 00:01:29,200
Note that we're using onCreateView,
rather than oncreateDialog. In the

9
00:01:29,200 --> 00:01:35,100
appDialog class we used a dialog builder in
the onCreateDialog function. Here, we're

10
00:01:35,100 --> 00:01:39,800
inflating the view from a layout
resource file in onCreateView.

11
00:01:39,800 --> 00:01:43,520
Be careful if you mix the two functions in
the same class. You can get unexpected

12
00:01:43,530 --> 00:01:48,660
problems. We need to access the
individual widgets, which is why we're

13
00:01:48,660 --> 00:01:55,170
inflating a view in onCreateView, rather
than using a dialog builder. Alright, we

14
00:01:55,170 --> 00:01:59,010
want to set up the onClickListeners for
our buttons, which we'll do in the

15
00:01:59,010 --> 00:02:02,790
onViewCreated function.
I'll get Android Studio to generate that

16
00:02:02,790 --> 00:02:07,240
one as well, after onCreateView.

17
00:02:30,900 --> 00:02:36,700
I'll write the save values function later. If
the user taps the OK button, we'll save

18
00:02:36,700 --> 00:02:41,709
the values and dismiss the dialogue. If
they tap cancel, we'll just dismiss the

19
00:02:41,709 --> 00:02:47,060
dialogue. A dialog isn't going to do a
lot at the moment but we can test it.

20
00:02:47,060 --> 00:02:54,900
Firstly, we add code in MainActivity, in
the onOptionsItemDelected function.

21
00:02:59,189 --> 00:03:05,760
Uncomment this line and replace the true.

22
00:03:10,079 --> 00:03:19,150
Alright, we can run the app and test our
settings dialog. When I choose settings

23
00:03:19,150 --> 00:03:27,069
from the menu, our dialog appears. The day
that starts the week can be selected

24
00:03:27,069 --> 00:03:33,040
from the spinner widget, which drops down
to show all the days we defined in the

25
00:03:33,040 --> 00:03:42,009
string array. I can also drag the seek-bar
left and right, but we're not getting the

26
00:03:42,009 --> 00:03:47,019
value to show yet and nothing's being
saved. But our basic settings dialog is

27
00:03:47,019 --> 00:03:50,379
working. We've still got a bit more work
to do.

28
00:03:50,380 --> 00:03:56,880
It would look a lot better with a title too.
I'll tap OK to dismiss the dialogue,

29
00:03:56,880 --> 00:03:59,700
and we'll continue with the code in the
next video.

30
00:03:59,709 --> 00:04:02,669
I'll see you there.
