1
00:00:00,670 --> 00:00:05,527
Back in the ColorWheel class,
let's change getColor to return an int,

2
00:00:05,527 --> 00:00:06,967
instead of a string.

3
00:00:10,021 --> 00:00:13,890
And now we need to convert
the string color to an int.

4
00:00:13,890 --> 00:00:18,789
Right above the return statement,
let's add a new int variable named color.

5
00:00:21,263 --> 00:00:27,159
And let's set it equal to
Color with a capital C, dot.

6
00:00:27,159 --> 00:00:32,134
And then if we start typing parseColor, we
can see that parseColor is a method that

7
00:00:32,134 --> 00:00:37,530
takes in a colorString and returns an int,
just what we're looking for.

8
00:00:37,530 --> 00:00:40,050
Hit Enter to select it and
add a semicolon.

9
00:00:41,160 --> 00:00:46,410
The parseColor method is a handy utility
method that takes a hexadecimal string,

10
00:00:46,410 --> 00:00:48,420
just like we have up here, and

11
00:00:48,420 --> 00:00:53,350
converts it to an integer representation
that Android can understand.

12
00:00:53,350 --> 00:00:56,506
So instead of returning
a randomly selected color string,

13
00:00:56,506 --> 00:01:00,050
let's pass that random color
string into the parseColor method.

14
00:01:06,841 --> 00:01:10,428
Finally, since we need to
be returning an integer,

15
00:01:10,428 --> 00:01:15,490
let's return our new color variable and
head back to fun facts activity.

16
00:01:17,590 --> 00:01:21,250
Now, instead of a string,
we're returning an int.

17
00:01:21,250 --> 00:01:23,495
So color should be an int, not a string.

18
00:01:26,136 --> 00:01:30,584
Looks good, now let's run our app and
verify it's working as we expect it to.

19
00:01:33,678 --> 00:01:41,150
Okay, moment of truth, tap the button,
and nice, all sorts of different colors.

20
00:01:42,620 --> 00:01:46,510
There's one more thing I'd like
to do here, one last color.

21
00:01:46,510 --> 00:01:50,120
Notice that the color of
the button text is black, but

22
00:01:50,120 --> 00:01:53,000
in our mock ups,
it's matching the background color.

23
00:01:53,000 --> 00:01:54,730
Let's go back to our code and change this.

24
00:01:56,328 --> 00:02:00,310
In the onClick method,
we already have the color we want to use.

25
00:02:00,310 --> 00:02:03,940
And we already have a variable for
our button, showFactButton.

26
00:02:03,940 --> 00:02:07,800
Let's add a new line at the bottom of
onClick and add a reference to our button.

27
00:02:10,080 --> 00:02:12,050
Now let's look for the method we need.

28
00:02:12,050 --> 00:02:17,070
Let's type .set and
we're looking for text color.

29
00:02:17,070 --> 00:02:20,940
So let's add text, and then down here,

30
00:02:20,940 --> 00:02:26,330
we see a method called setTextColor
that takes on an int parameter.

31
00:02:26,330 --> 00:02:27,060
Let's pick that one.

32
00:02:28,410 --> 00:02:29,920
Then let's pass in our color variable.

33
00:02:31,810 --> 00:02:34,410
And cool, but we're not quite done.

34
00:02:34,410 --> 00:02:38,500
We're only changing the text color
after the button has been tapped.

35
00:02:38,500 --> 00:02:42,310
If the button hasn't been tapped,
we'll still see black text.

36
00:02:42,310 --> 00:02:45,580
We should change our button's default
text color to match the default

37
00:02:45,580 --> 00:02:46,790
background, green.

38
00:02:46,790 --> 00:02:50,430
Let's go back into our
activity_fun_facts layout file.

39
00:02:50,430 --> 00:02:51,900
And make sure we're on the Design tab.

40
00:02:53,410 --> 00:02:54,901
Then let's select our relativeLayout.

41
00:02:57,663 --> 00:03:00,160
And copy the green color from
the background property.

42
00:03:02,260 --> 00:03:06,981
Then let's select our button,
scroll down to the textColor property.

43
00:03:12,273 --> 00:03:18,230
Paste in our color, hit Enter,
and there we go, green text.

44
00:03:18,230 --> 00:03:20,127
Now let's run the app to
make sure everything works.

45
00:03:24,133 --> 00:03:28,096
Okay, just like we expected,
lots of different colors for

46
00:03:28,096 --> 00:03:32,469
the background and lots of different
colors for our button text.

47
00:03:32,469 --> 00:03:36,565
All right, that's really coming together.

48
00:03:36,565 --> 00:03:38,459
We're done with all the programming, but

49
00:03:38,459 --> 00:03:41,990
there's still one little thing before we
can move on to testing and debugging.
