1. Title:
   Show Shapes Code
2. Description:

3. 310 0:00 - 0:03
   So I'm just going to show how I added
   the polyline to the map with all my
4. 3000 0:03 - 0:04
   different ice rinks.
5. 4000 0:04 - 0:07
   So to draw the polyline, I set up
   the latitudes and longitudes for
6. 6898 0:07 - 0:10
   all the different ice rinks, Renton,
   Kirkland, Everett, Lynnwood, etc.
7. 10444 0:10 - 0:13
   And this time I'm just setting
   them as LatLng objects.
8. 12650 0:13 - 0:15
   Earlier they were marker options,
   but now they're just latitudes and
9. 15270 0:15 - 0:16
   longitudes.
10. 16430 0:16 - 0:21
    I set up my camera position to be
    exactly as I did in the earlier sample.
11. 20510 0:21 - 0:24
    Now in my onMapReady, I just move
    the camera to my camera position,
12. 24276 0:24 - 0:25
    which is Seattle.
13. 25341 0:25 - 0:28
    And then to draw the polyline
    I just call map.Polyline.
14. 28090 0:28 - 0:30
    It's a new Polyline object,
    geodesic true,
15. 30440 0:30 - 0:35
    and then I just add all
    of the latitudes and
16. 34810 0:35 - 0:39
    longitudes that I had created earlier,
    Renton, Kirkland, Everett, Lynnwood.
17. 39200 0:39 - 0:43
    Notice that I begin at Renton and
    I also add Renton at the end.
18. 42560 0:43 - 0:45
    And then this just closes the shape.
19. 44690 0:45 - 0:48
    Because what will happen when you draw a
    polyline is it will draw from Renton to
20. 47760 0:48 - 0:51
    Kirkland, from Kirkland to Everett,
    from Everett to Lynnwood, etc.
21. 51260 0:51 - 0:53
    So, if I want to close the shape,
22. 52600 0:53 - 0:56
    I just want to go back to
    the initial one at the end.
23. 56160 0:56 - 1:01
    And then I will get all my rinks drawn
    into a polygon like shape by adding
24. 60999 1:01 - 1:02
    a polyline.
25. 61910 1:02 - 1:04
    And this is what it will look like.
26. 63830 1:04 - 1:07
    Here you can see on my tablet I
    have the same map of Seattle, and
27. 66880 1:07 - 1:10
    I have all the endpoints
    of the different rinks.
28. 69670 1:10 - 1:13
    My home rink of Renton that I showed
    earlier on is the beginning and
29. 72990 1:13 - 1:17
    ending point, and then the polylines
    get drawn from Renton to other rinks.
30. 77330 1:17 - 1:21
    So for example,
    this is the rink in Kingsgate.
31. 80652 1:21 - 1:23
    You can see,
    Kingsgate highlighted there.
32. 82830 1:23 - 1:26
    Or I can go all the way
    the rink in Everett, etc.
33. 85810 1:26 - 1:29
    So, these are the polylines that I've
    drawn from me connecting the rinks.
34. 89430 1:29 - 1:34
    And because I just joined the last rink
    at ShoWare back to Renton in my code
35. 93684 1:34 - 1:36
    the shape gets completed.
36. 96150 1:36 - 1:39
    And as you can see here,
    my second last one was ShoWare.
37. 99230 1:39 - 1:42
    I then added Renton and
    the shape got completed.
38. 101600 1:42 - 1:44
    So my polyline actually
    became a polygon.
39. 104380 1:44 - 1:47
    You can actually also
    do a map.addPolygon and
40. 107440 1:47 - 1:50
    specify the endpoints and
    it will auto close it for you.
