1
00:00:00,330 --> 00:00:02,540
We just finished getting our cursor, and

2
00:00:02,540 --> 00:00:07,158
now that we've got it let's loop through
it and add each contact to our list.

3
00:00:07,158 --> 00:00:12,780
But first we'll need to make sure that
our cursor both exists and isn't empty.

4
00:00:12,780 --> 00:00:19,913
So let's type if (cursor != to
null to make sure it exists,

5
00:00:19,913 --> 00:00:28,292
and then add && cursor.moveToFirst
to make sure there is a first row.

6
00:00:28,292 --> 00:00:33,654
MoveToFirst returns false if there
is not a first row to move to.

7
00:00:33,654 --> 00:00:39,490
Inside the if statement we can use the do
while loop to loop through our cursor.

8
00:00:39,490 --> 00:00:41,980
So do and then brackets.

9
00:00:43,990 --> 00:00:47,865
And we'll leave the inside blank for
now and at the end add

10
00:00:47,865 --> 00:00:54,310
while(cursor.moveToNext.

11
00:00:54,310 --> 00:00:55,220
And add a semicolon.

12
00:00:56,800 --> 00:01:00,280
This way, as long as there's
another row we'll keep looping.

13
00:01:01,450 --> 00:01:06,700
Inside the loop, we just need to get
the ID and name of our contact and

14
00:01:06,700 --> 00:01:10,660
then use that to create a new
text view for a linear layout.

15
00:01:10,660 --> 00:01:15,393
Let's create a new string
variable named id and

16
00:01:15,393 --> 00:01:19,072
set it equal to cursor.getString.

17
00:01:19,072 --> 00:01:23,511
And then for the column index,

18
00:01:23,511 --> 00:01:29,680
let's pass in Cursor.getColumnIndex.

19
00:01:29,680 --> 00:01:32,370
And then that requires the column name, so

20
00:01:32,370 --> 00:01:37,350
let's pass in DatabaseHelper.COLUMN_ID and
there we go.

21
00:01:38,680 --> 00:01:41,330
And now that we've got our ID,
let's use command or

22
00:01:41,330 --> 00:01:43,810
control D to duplicate this line.

23
00:01:43,810 --> 00:01:48,704
And then let's just change

24
00:01:48,704 --> 00:01:53,190
id to name and ID to NAME.

25
00:01:53,190 --> 00:01:54,610
Then let's create a new TextView.

26
00:01:57,380 --> 00:02:02,290
TextView textView = getNewTextView, and

27
00:02:02,290 --> 00:02:05,075
parse in id and name, and

28
00:02:05,075 --> 00:02:10,923
then let's add that text
view to our linear layout.

29
00:02:10,923 --> 00:02:15,240
Linear Layout.addView textView.

30
00:02:16,590 --> 00:02:23,840
And finally after the loop we need to
close our cursor, cursor.close and

31
00:02:23,840 --> 00:02:27,920
that's it, we're now using a content
provider to serve up our data.

32
00:02:27,920 --> 00:02:30,510
But before we run the app,
there's one more thing we should do.

33
00:02:32,471 --> 00:02:39,250
Over in the manifest, we need to declare
our provider inside the application tags.

34
00:02:39,250 --> 00:02:40,460
Let's add a couple lines at the bottom.

35
00:02:42,696 --> 00:02:45,526
And then, add a provider tag and
let it auto complete.

36
00:02:47,345 --> 00:02:51,968
Next, for the authorities, let's pass
in our authority, which remember,

37
00:02:51,968 --> 00:02:55,290
is just the package name, plus provider.

38
00:02:55,290 --> 00:02:57,058
So for me it's going to be

39
00:02:57,058 --> 00:03:04,150
com.teamtreehouse.contentproviders.provi-
der.

40
00:03:04,150 --> 00:03:06,390
And for the name,
let's give it our content provider.

41
00:03:09,580 --> 00:03:12,629
Then let's close our provider tag and
run the app.

42
00:03:19,524 --> 00:03:21,310
Looks good so far.

43
00:03:21,310 --> 00:03:26,940
Now let's see what happens when we type in
a name like Stan and then hit the button.

44
00:03:28,470 --> 00:03:29,230
Sweet.

45
00:03:29,230 --> 00:03:35,010
It added the name to the list and we got a
toast of the URI where the name is stored.

46
00:03:35,010 --> 00:03:37,270
Let's add another name to get
a better look at that URI.

47
00:03:38,660 --> 00:03:41,590
Let's type Maddy and
then click the button.

48
00:03:43,340 --> 00:03:48,660
And we've got the URI of the new row as
the content URI plus the ID of the row.

49
00:03:50,900 --> 00:03:55,000
Awesome our content provider is
all set up, and it works great.

50
00:03:55,000 --> 00:03:58,120
But, so
far it's only being used by one app, so

51
00:03:58,120 --> 00:04:01,090
we're not getting much benefit
from our content provider.

52
00:04:01,090 --> 00:04:03,480
In the next video we'll
create another app and

53
00:04:03,480 --> 00:04:06,480
see how we can access our content
provider from the outside.
