1 00:00:00,180 --> 00:00:04,920 So as you can see here these are the lines of code that I pasted here. 2 00:00:04,950 --> 00:00:07,860 So as you can see here I pasted our list preference. 3 00:00:07,860 --> 00:00:14,130 So this means that you're going to have a radio group that contains radio buttons right. 4 00:00:14,150 --> 00:00:18,710 So as you can see here first we need to actually put the entries attribute. 5 00:00:18,710 --> 00:00:20,380 So Android entries. 6 00:00:20,510 --> 00:00:26,120 And as you can see here I referred to this as sign Ari and this means that you are referring to this 7 00:00:26,180 --> 00:00:29,180 address that exemplified slash colors. 8 00:00:29,180 --> 00:00:33,600 So now there's actually capitis colors here and now. 9 00:00:33,710 --> 00:00:36,670 Let's actually go inside this area is that exemplified. 10 00:00:36,920 --> 00:00:40,400 And here let's create I think add a resource here. 11 00:00:40,410 --> 00:00:43,690 So just open a tag and just type in here streambed at 8. 12 00:00:43,970 --> 00:00:51,530 And for the name just a place that's value here colors and then I'll just close the stack and now inside 13 00:00:51,530 --> 00:00:55,910 this string and here I am going to pasting some lines of code here and then I'm going to explain to 14 00:00:55,910 --> 00:00:58,090 you what's going on here. 15 00:00:58,100 --> 00:01:02,420 So as you can see here these are the lines of code that I pasted here. 16 00:01:02,420 --> 00:01:06,590 So if you've got these items inside these colors starting at 8. 17 00:01:06,650 --> 00:01:10,110 So the first item is the color of white as you can see here. 18 00:01:10,130 --> 00:01:12,400 The second item is the color black. 19 00:01:12,430 --> 00:01:15,290 The first item is actually the color green. 20 00:01:15,350 --> 00:01:17,690 The fourth item is the color red. 21 00:01:17,750 --> 00:01:23,370 The fifth item is the color blue and the six color as you can see here is yellow. 22 00:01:23,510 --> 00:01:27,730 So these values are going to be the values that we are going to show to the user. 23 00:01:27,740 --> 00:01:32,690 So now if we actually show you the emulator here now as you can see here if I just click on this choose 24 00:01:32,690 --> 00:01:35,070 background color here as you can see here. 25 00:01:35,180 --> 00:01:37,980 These are the values that we are going to show to the user. 26 00:01:38,000 --> 00:01:38,450 Right. 27 00:01:38,630 --> 00:01:43,970 And if we actually select one of these values for example green and if I click on this back a patch 28 00:01:44,030 --> 00:01:49,340 button here as you can see now the background color of our Quiz application is clean. 29 00:01:49,400 --> 00:01:50,090 Right. 30 00:01:50,090 --> 00:01:51,890 So these are the values. 31 00:01:51,920 --> 00:01:55,510 As you can see here these are the values that we are going to show to the user. 32 00:01:55,550 --> 00:01:59,680 And here we created this thing Arrey in order to show these values to the user. 33 00:01:59,690 --> 00:02:00,320 Right. 34 00:02:00,320 --> 00:02:04,640 So let's go back to our Kulis underlined preferences that they. 35 00:02:04,850 --> 00:02:11,460 And here we have entry values and again are you referred to this phrase that exemplified at sign at 36 00:02:11,460 --> 00:02:17,050 a slash coloreds again are you referred to this string area here. 37 00:02:17,390 --> 00:02:23,300 So this means that we are going to actually interact also with these values that we are going to show 38 00:02:23,300 --> 00:02:24,290 to the user. 39 00:02:24,500 --> 00:02:28,330 The color of white black green red blue or yellow. 40 00:02:28,450 --> 00:02:32,500 We are going to interact with these values from our Java coats later. 41 00:02:32,780 --> 00:02:37,130 So that's what actually referred here to this color. 42 00:02:37,360 --> 00:02:41,910 String art twice once for these entries and once for these entry values. 43 00:02:41,930 --> 00:02:42,990 Right. 44 00:02:42,990 --> 00:02:46,250 So and as you can see here we have these key attributes. 45 00:02:46,280 --> 00:02:50,980 So the key attribute is actually the key that we're going that we need here. 46 00:02:50,990 --> 00:02:52,440 This works as an ID. 47 00:02:52,610 --> 00:02:59,030 So you need this key in order to actually interact with this list preferences later inside our Java 48 00:02:59,050 --> 00:02:59,700 coats. 49 00:02:59,720 --> 00:03:04,670 So the key is settings underline quis underline background underline color. 50 00:03:04,850 --> 00:03:07,220 So if you have a title as you can see here. 51 00:03:07,400 --> 00:03:12,110 So the title is as you can see here at the title that you're going to show to the user. 52 00:03:12,120 --> 00:03:14,640 So now let me show you the emulator here. 53 00:03:14,630 --> 00:03:18,550 As you can see the title is True's background color as you can see here. 54 00:03:18,710 --> 00:03:20,820 So as you can see at sidestream. 55 00:03:20,900 --> 00:03:26,770 So here we are referring to these strings that XML file slash choose background color. 56 00:03:26,770 --> 00:03:28,750 So let's actually copy this name here. 57 00:03:28,750 --> 00:03:30,060 Choose by the color. 58 00:03:30,230 --> 00:03:33,180 And then let's go inside this string that exemplified. 59 00:03:33,320 --> 00:03:36,680 And now let's actually create another string resource. 60 00:03:36,770 --> 00:03:39,060 So just open attack and just type in here strange. 61 00:03:39,290 --> 00:03:44,690 And for the name just paste that value here choose underlined by the underlined color. 62 00:03:44,840 --> 00:03:47,210 And now let's actually close this tag here. 63 00:03:47,360 --> 00:03:50,990 So now let's just type in here as you can see here. 64 00:03:51,390 --> 00:03:54,110 We need to just type in here is what you choose background color. 65 00:03:54,230 --> 00:04:03,280 So here I can just type in Choose background color as you can see here. 66 00:04:03,410 --> 00:04:10,280 So now let's actually go back inside our cubes underlined preferences that they said file. 67 00:04:10,520 --> 00:04:16,190 Now as you can see here the error is gone and we have also these Summerlee attributes which again refers 68 00:04:16,190 --> 00:04:23,060 to this stream that exemplifies So same strange slash choose color description so that the description 69 00:04:23,060 --> 00:04:28,170 is disvalue choose up on one of these colors as the background color. 70 00:04:28,170 --> 00:04:30,360 So as you can see here we have a typo here. 71 00:04:30,440 --> 00:04:34,070 I didn't actually typed this but you're right. 72 00:04:34,070 --> 00:04:37,560 So let's actually write it here correctly. 73 00:04:37,670 --> 00:04:39,080 So just copy this value here. 74 00:04:39,080 --> 00:04:44,720 Choose color description and now this to go inside the string that exemplified. 75 00:04:45,140 --> 00:04:47,960 And now let's create a strange resource. 76 00:04:47,960 --> 00:04:48,790 So it's three. 77 00:04:48,980 --> 00:04:53,390 And the name is going to be this value that we copy it choose color description. 78 00:04:53,400 --> 00:05:00,000 And now let's actually close this this attack here and now as you can see here for the description I 79 00:05:00,000 --> 00:05:03,780 had just type in Choose one of these colors as the background color. 80 00:05:03,890 --> 00:05:08,600 So here I can just taping choose one of these 81 00:05:11,340 --> 00:05:19,450 colors as back get them color. 82 00:05:20,430 --> 00:05:21,140 Right. 83 00:05:21,150 --> 00:05:23,730 So as you can see here this is going to be the description. 84 00:05:24,270 --> 00:05:27,360 And now as you can see this is the description right. 85 00:05:27,360 --> 00:05:31,730 So now let's actually go back inside our quiz underlined preferences that exemplified. 86 00:05:31,770 --> 00:05:34,540 And now as you can see here again the error is gone. 87 00:05:34,710 --> 00:05:37,740 And again for the assistant to be assigned a value. 88 00:05:37,730 --> 00:05:38,180 True. 89 00:05:38,310 --> 00:05:44,300 So this persistent attribute is going to persist at these settings or to their shared preferences. 90 00:05:44,310 --> 00:05:51,360 As you can see here and then later when you want to actually run for an application for the next time 91 00:05:52,710 --> 00:05:57,870 you can actually read those settings for the shared for instance file that we have inside our Android 92 00:05:57,870 --> 00:05:58,620 device. 93 00:05:58,620 --> 00:06:05,250 So this is very important that you assign the value true for this attribute and we have also the default 94 00:06:05,250 --> 00:06:09,880 value so for the for example for the first time that our application is going to be run on the user's 95 00:06:09,900 --> 00:06:15,920 device if you're going to use this a default value as you can see here again you referred to these strings 96 00:06:15,930 --> 00:06:16,730 that exemplified. 97 00:06:16,810 --> 00:06:21,580 And I just typed in at sign streambed slash default color black. 98 00:06:21,600 --> 00:06:24,430 So we use the color black as the default value right. 99 00:06:24,450 --> 00:06:30,810 So let's actually copy this value here and now let's actually go inside this string that XML file here. 100 00:06:31,770 --> 00:06:34,760 And now let's actually create another string resource. 101 00:06:34,760 --> 00:06:39,450 So just open a tag and just type in a string and for the name just paste that value here. 102 00:06:39,450 --> 00:06:43,100 Default color black and let's close this page here. 103 00:06:43,110 --> 00:06:47,690 And for the value I can just type in here black as you can see here. 104 00:06:47,700 --> 00:06:49,840 So this is going to be the default value right. 105 00:06:49,850 --> 00:06:55,260 I remember that this is really important that you put this name here with capital B as you can see here 106 00:06:55,770 --> 00:06:58,950 inside these arrows that exemplified. 107 00:06:59,130 --> 00:07:05,460 We have these values as you can see white with capital W blacks with capital B green with capital G 108 00:07:05,790 --> 00:07:12,520 red capital R and blue the capital B and yellow with capital Y and this means that B. 109 00:07:12,780 --> 00:07:15,590 Because these values are written in. 110 00:07:15,840 --> 00:07:20,670 As you can see here in this way when we want to actually provide a default value that default value 111 00:07:20,850 --> 00:07:24,030 also must be actually treated as. 112 00:07:24,090 --> 00:07:27,860 That way that we put this value inside arrays that are exempt. 113 00:07:28,020 --> 00:07:34,140 As you can see here because inside is Ariz that him and here for example we put the value big Blache 114 00:07:34,170 --> 00:07:39,860 with capital B then we want to provide a default value for our list preferences. 115 00:07:39,870 --> 00:07:44,960 We need to actually put that value the same here with capital B as you can see here. 116 00:07:44,970 --> 00:07:46,280 So this is really important. 117 00:07:46,290 --> 00:07:50,620 So let's actually go inside Ahlquist that underline preferences that exemplified. 118 00:07:50,940 --> 00:07:53,100 And now as you can see here the error is gone. 119 00:07:53,100 --> 00:07:53,720 Right. 120 00:07:54,000 --> 00:07:58,950 So now I want to actually paste in some more lines of code here and then I'm going to explain to you 121 00:07:59,160 --> 00:08:00,760 what's going on here.
