1
00:00:00,470 --> 00:00:04,260
We're broadcasting our data to the world,
but is anyone listening?

2
00:00:04,260 --> 00:00:06,390
Unfortunately, there's not an easy way for

3
00:00:06,390 --> 00:00:09,440
us to receive this data
in the on update method.

4
00:00:09,440 --> 00:00:14,000
If we flip over to widget provider,
it's clear that there's no way for

5
00:00:14,000 --> 00:00:17,510
us to access the intent and
side on update.

6
00:00:17,510 --> 00:00:22,560
And remember, app widget providers
are just specialized broadcast receivers.

7
00:00:22,560 --> 00:00:26,900
So, the first step in anything
happening here is a call to on receive

8
00:00:26,900 --> 00:00:28,830
where we get an intent.

9
00:00:28,830 --> 00:00:33,040
But, again, it looks like that intent
isn't being passed into on update.

10
00:00:34,050 --> 00:00:37,710
To solve this issue, we're going to
need to create our own action and

11
00:00:37,710 --> 00:00:40,530
override on receive to handle it.

12
00:00:40,530 --> 00:00:44,070
Let's start by creating a new constant
to hold the name of our action.

13
00:00:45,140 --> 00:00:49,830
So public static final String,
and let's call it TOAST_ACTION.

14
00:00:49,830 --> 00:00:55,687
And set it equal to your package name,

15
00:00:55,687 --> 00:00:58,988
dot TOAST_ACTION.

16
00:01:01,677 --> 00:01:07,547
And now, down in me on update function,
where we set the action for our intent,

17
00:01:07,547 --> 00:01:12,718
instead of using
appWidgetManager.ACTION_APPWIDGET_UPDATE,

18
00:01:12,718 --> 00:01:15,470
let's just use our TOAST_ACTION.

19
00:01:15,470 --> 00:01:20,050
All that's left is overwriting on
receive to handle our new action.

20
00:01:20,050 --> 00:01:23,360
Let's add a couple lines
below our constants and

21
00:01:23,360 --> 00:01:26,200
then use control O to override on receive.

22
00:01:27,320 --> 00:01:30,760
Then let's add a line at the top and

23
00:01:30,760 --> 00:01:34,123
check if the intent parameter
has an action of toast action.

24
00:01:34,123 --> 00:01:39,138
So if intent.getAction,

25
00:01:39,138 --> 00:01:44,160
that equals toast action.

26
00:01:44,160 --> 00:01:48,050
And if it is a toast action, let's create
a new string to hold the list item,

27
00:01:49,130 --> 00:01:56,500
string list item, and let's set it
equal to intent.getstringextra and

28
00:01:56,500 --> 00:01:58,750
pass in our key, key item.

29
00:02:00,000 --> 00:02:02,980
Finally, let's toast what item this is.

30
00:02:02,980 --> 00:02:06,210
And to make it easier,
let's pick the create a new toast version.

31
00:02:07,420 --> 00:02:10,590
And for the second parameter,
lets pass on our new list item stream.

32
00:02:12,340 --> 00:02:14,120
Now let's run the app and
see what we've got.

33
00:02:17,250 --> 00:02:20,777
And again, it looks like we need to
drag out new instances of our widget.

34
00:02:26,345 --> 00:02:30,630
Okay, so we've just added the toasts,
and now when we click on an item,

35
00:02:30,630 --> 00:02:34,100
we see which item it is
toasting down there.

36
00:02:34,100 --> 00:02:36,490
But it looks like we've
lost the colors again.

37
00:02:36,490 --> 00:02:40,960
When we changed our action away from the
normal update action, not only did we gain

38
00:02:40,960 --> 00:02:46,180
the ability to use our own action, but
we also broke its connection to On Update.

39
00:02:46,180 --> 00:02:50,080
So we're not going to get any calls
to On Update with our toast action.

40
00:02:50,080 --> 00:02:54,780
However, what we can do is
just call On Update ourselves

41
00:02:54,780 --> 00:02:56,350
whenever we receive a toast action.

42
00:02:58,630 --> 00:03:01,940
Let's add a line below our toast and
then call On Update.

43
00:03:01,940 --> 00:03:06,075
Then let's pass on our context and
an app widget manager,

44
00:03:06,075 --> 00:03:11,080
AppWidgetManager.getInstance and
pass in our context.

45
00:03:11,080 --> 00:03:15,160
And then, since we aren't really using
the appWidgetIds parameter anyway,

46
00:03:15,160 --> 00:03:16,130
let's just pass it null.

47
00:03:17,320 --> 00:03:21,530
Now, if we run the app again,
the background changes and

48
00:03:21,530 --> 00:03:23,150
we get a toast, great work.

49
00:03:24,280 --> 00:03:25,890
But before I let you go,

50
00:03:25,890 --> 00:03:28,420
let's quickly look at another way
that we could have solved that.

51
00:03:29,480 --> 00:03:33,260
Back in the on receive function,
lets delete the on update call,

52
00:03:36,320 --> 00:03:40,926
and instead let's just set the action for
this intent to the update action,

53
00:03:40,926 --> 00:03:48,380
intent.setaction App widget
manager.action at widget update.

54
00:03:49,520 --> 00:03:54,590
Now, when we receive an intent with our
toast action, we'll toast our list item,

55
00:03:54,590 --> 00:03:59,110
and then change the intense action
to action app widget update.

56
00:03:59,110 --> 00:04:01,860
Then, when we call super.onreceive,

57
00:04:01,860 --> 00:04:05,310
it will have an intent that
triggers the on update method.

58
00:04:05,310 --> 00:04:11,660
And if we run the app just one more time,
it still works.

59
00:04:11,660 --> 00:04:12,434
Nice.

60
00:04:14,012 --> 00:04:17,490
Widgets are certainly not the most
straightforward part of Android.

61
00:04:17,490 --> 00:04:20,750
But at least now you've got
some idea of why that is.

62
00:04:20,750 --> 00:04:24,320
Not to mention you've also got
a pretty sweet color changing widget.

63
00:04:24,320 --> 00:04:28,460
And you understand how to add actions to
not only the views in your remote views,

64
00:04:28,460 --> 00:04:31,160
but also individual list items.

65
00:04:31,160 --> 00:04:32,650
Now that you've conquered widgets,

66
00:04:32,650 --> 00:04:35,860
hopefully the rest of Android
will seem a little bit easier.

67
00:04:35,860 --> 00:04:37,790

00:04:37,790 --> 00:04:41,570
