1 00:00:00,570 --> 00:00:05,280 And here as you can see again I gave a key to this checkbox preference. 2 00:00:05,340 --> 00:00:09,540 So the key is going to be checkbox Front number two text one. 3 00:00:09,750 --> 00:00:13,680 So as you can see here in our project structure I have a free Faunce. 4 00:00:13,860 --> 00:00:21,710 So I created free checkbox preferences for free for all of these fonts that I have in my assets folder. 5 00:00:21,840 --> 00:00:23,600 Inside these forms directory. 6 00:00:23,850 --> 00:00:25,420 The first one is for this chunk. 7 00:00:25,450 --> 00:00:27,210 Five Auty of font. 8 00:00:27,270 --> 00:00:32,020 And the second one is is going to be for this Fauntleroy Blount that PTF font. 9 00:00:32,190 --> 00:00:38,700 And the first one tick tick box preference is going to be for this wunderbar the more that you have. 10 00:00:38,700 --> 00:00:41,560 So let's go back to our preferences underlined for that example. 11 00:00:41,580 --> 00:00:49,680 So here I have this checkbox preference and the key is going to be checkbox font number to text 1. 12 00:00:49,920 --> 00:00:52,530 So this is going to be the font for our text. 13 00:00:52,530 --> 00:00:54,600 One phone number two right. 14 00:00:54,660 --> 00:00:57,170 I have this font here font literally Brown. 15 00:00:57,870 --> 00:01:04,640 And now I gave a title to this checkbox preference that the title is going to be the name of the font. 16 00:01:04,740 --> 00:01:10,130 Fauntleroy Brown and the Summary The description is going to be this is phone number two. 17 00:01:10,440 --> 00:01:11,130 OK. 18 00:01:11,490 --> 00:01:16,820 And the default value is going to be the phone the name of the phone itself in the double quotes Fauntleroy 19 00:01:16,830 --> 00:01:25,110 Brown that data TGF And as you can see here I am actually ending artistic experience by putting this 20 00:01:25,650 --> 00:01:28,550 closing tag here checkbox preference. 21 00:01:28,560 --> 00:01:29,250 OK. 22 00:01:29,700 --> 00:01:36,380 So here again I have another checkbox preference for this first format that she is going to be checkbox 23 00:01:36,620 --> 00:01:37,110 for. 24 00:01:37,160 --> 00:01:39,610 Number of free text 1. 25 00:01:39,750 --> 00:01:47,430 Ok phone number free for the text 1 are actually gave a wrong name to this of the first form the name 26 00:01:47,430 --> 00:01:49,780 of the first phone is wunderbar. 27 00:01:49,860 --> 00:01:51,750 Space them all that what you have. 28 00:01:51,870 --> 00:01:53,140 So this is run OK. 29 00:01:53,310 --> 00:02:00,750 So I need to actually delete this name here for the title and I need to actually put the same name that 30 00:02:00,780 --> 00:02:04,150 I have here for this front one there. 31 00:02:04,890 --> 00:02:05,290 OK. 32 00:02:05,320 --> 00:02:07,370 One dead body. 33 00:02:07,600 --> 00:02:09,730 Space them all. 34 00:02:10,270 --> 00:02:10,730 OK. 35 00:02:10,840 --> 00:02:12,260 That's all. 36 00:02:12,460 --> 00:02:15,510 So now this is the right name for this font. 37 00:02:15,840 --> 00:02:16,520 OK. 38 00:02:16,830 --> 00:02:19,690 And again I have this summary that is phone number free. 39 00:02:19,710 --> 00:02:22,480 And again as you can see I have this default value right. 40 00:02:22,620 --> 00:02:26,360 So as you can see here I put this Auty here. 41 00:02:26,640 --> 00:02:28,420 It's not necessary to put this all to you. 42 00:02:28,440 --> 00:02:31,910 This is just the titel delete this OTFE here. 43 00:02:32,040 --> 00:02:32,640 OK. 44 00:02:32,940 --> 00:02:37,500 So now for the default value again I have this wrong value here. 45 00:02:37,500 --> 00:02:37,890 OK. 46 00:02:37,980 --> 00:02:45,100 So this value is must be the same as these are to name here wunderbar spaced them more that what you 47 00:02:45,110 --> 00:02:45,230 have. 48 00:02:45,240 --> 00:02:49,760 So again I'm going to type in wunderbar wonder but. 49 00:02:50,150 --> 00:02:50,540 OK. 50 00:02:50,550 --> 00:02:54,970 Space them all that OTTF. 51 00:02:55,200 --> 00:02:57,210 OK so this is going to be the default value. 52 00:02:57,210 --> 00:02:58,930 So this is really important. 53 00:02:59,010 --> 00:03:04,530 They must be the same as the name of this phone here and here as you can see this is just a title in 54 00:03:04,530 --> 00:03:10,380 order to let the user know what is going to be the name of the actual type that they want to use. 55 00:03:10,380 --> 00:03:19,270 So this is very important that you use that is actually the best name the right name for your Fontenay. 56 00:03:19,290 --> 00:03:19,920 OK. 57 00:03:20,220 --> 00:03:26,970 And here I am actually closing this preference this checkbox preference here by putting disclosing tack 58 00:03:27,000 --> 00:03:33,870 here as you can see and now again inside these preferences Underland find examine as you can see I have 59 00:03:33,870 --> 00:03:39,640 this preference category so I actually created this category for text number one. 60 00:03:39,870 --> 00:03:46,080 And these are going to be the checkboxes for text number one in order to let the user select a specific 61 00:03:46,080 --> 00:03:49,960 font for text number one that you can see on this emulator for this. 62 00:03:50,040 --> 00:03:51,030 This is text number one. 63 00:03:51,030 --> 00:03:51,640 Right. 64 00:03:51,960 --> 00:03:55,920 And here as you can see I have this list preference. 65 00:03:55,920 --> 00:03:57,060 So what is this. 66 00:03:57,420 --> 00:04:03,390 This list proofread this is going to show the user some radio buttons in order to let the user choose 67 00:04:03,390 --> 00:04:10,290 one of the options in order to specify the size of the text that they want to actually change. 68 00:04:10,290 --> 00:04:17,520 So here as you can see I have this list of friends I opened this task list preference and I gave a key 69 00:04:17,580 --> 00:04:18,780 to this list preference. 70 00:04:18,780 --> 00:04:22,770 The key is font underline size underline text 1. 71 00:04:22,830 --> 00:04:30,180 So remember that I told you always for your key names you just capitalized your key names. 72 00:04:30,180 --> 00:04:31,380 This is really important. 73 00:04:31,440 --> 00:04:35,600 And here as you can see I have this title here. 74 00:04:35,820 --> 00:04:42,360 The title is specify the size of your fonts for text view one as you can see here. 75 00:04:42,420 --> 00:04:49,560 Here I want to actually let the user know that I want to actually specify the size of the phones so 76 00:04:49,560 --> 00:04:51,150 that they know what to do. 77 00:04:51,150 --> 00:04:53,920 This is the title for this list preference. 78 00:04:53,940 --> 00:04:59,320 So remember this preference is going to actually show the user a list of radio buttons. 79 00:04:59,400 --> 00:05:03,560 So the user can only choose one of the two options. 80 00:05:03,580 --> 00:05:09,760 One of the radio buttons and then accordingly change the size of the text view that they want to change. 81 00:05:09,760 --> 00:05:15,940 So for this specific case we want to change the size of the text one. 82 00:05:15,990 --> 00:05:16,360 OK. 83 00:05:16,360 --> 00:05:21,910 We hope we are actually inside this preference category for this takes text number of settings as you 84 00:05:21,910 --> 00:05:22,770 can see here. 85 00:05:22,780 --> 00:05:26,470 So inside this preference category I have this list preference. 86 00:05:26,530 --> 00:05:29,970 The key is font size one font size takes one. 87 00:05:30,010 --> 00:05:35,250 The title is specified the size of your fonts for text you want. 88 00:05:35,410 --> 00:05:36,050 OK. 89 00:05:36,340 --> 00:05:39,890 And the dialog title is choose one of these sizes. 90 00:05:39,910 --> 00:05:46,000 So here it is going to be the title of the dialog that is going to be shown to the user so that they 91 00:05:46,000 --> 00:05:52,560 can see that it says choose one of these sizes and we have these entries and entry values. 92 00:05:52,810 --> 00:05:58,720 So these entries and three values are going to be the numbers that they use that can actually choose 93 00:05:58,720 --> 00:06:01,480 for the size of their text views. 94 00:06:01,510 --> 00:06:04,550 So in a minute I'll talk about that here. 95 00:06:04,810 --> 00:06:08,850 And here I have this default value the default value is 10. 96 00:06:08,860 --> 00:06:12,400 So the default text size value is going to be 10. 97 00:06:12,400 --> 00:06:17,290 So this is really important that actually provide a default value so when the user doesn't actually 98 00:06:17,500 --> 00:06:24,400 want to select any of the radio buttons or doesn't want to actually choose one of the text sizes the 99 00:06:24,400 --> 00:06:25,920 default value is going to be 10. 100 00:06:26,110 --> 00:06:29,700 So what are these in threes and three values. 101 00:06:29,770 --> 00:06:36,760 So I have these entries as you can see here are these entries at sign Arey slash font sizes. 102 00:06:36,820 --> 00:06:42,940 And here I have these three values at sign Aure slash font size font sizes values. 103 00:06:43,000 --> 00:06:50,360 So this at site Aure actually first try this treaty actually exemplified that we have in our project. 104 00:06:50,440 --> 00:06:58,990 So what is that exemplified that XML file is inside our values directory here inside our project structure 105 00:06:59,050 --> 00:07:03,460 values directory inside these strings that XML file here. 106 00:07:03,490 --> 00:07:04,330 So this at St.. 107 00:07:04,340 --> 00:07:08,860 Ara refers to this isn't exemplified strings that example. 108 00:07:09,100 --> 00:07:11,540 So let's double click on these strings that XML here. 109 00:07:11,560 --> 00:07:18,820 And as you can see here I have these values here resources and I have this value stream name app name. 110 00:07:18,820 --> 00:07:23,610 So this is going to be to specify the name of our actually application. 111 00:07:23,910 --> 00:07:30,990 And as you can see I have this XML value so now I won't actually paste in some lines of code here inside 112 00:07:31,000 --> 00:07:36,260 these resources tag here and then I'm going to explain to you what's going on here. 113 00:07:36,280 --> 00:07:43,170 So as you can see here inside these strings that XML file here I actually pasted these lines of code. 114 00:07:43,210 --> 00:07:45,250 So now I'm going to explain to you what's going on here. 115 00:07:45,250 --> 00:07:52,300 First of all as you can see I have this strange Arey tag here as you can see and the name of this tag 116 00:07:52,330 --> 00:07:54,470 is font sizes. 117 00:07:54,580 --> 00:08:00,850 So this is going to be the font size is that the users can use in order to change the size of the phones 118 00:08:00,910 --> 00:08:02,080 of their views. 119 00:08:02,110 --> 00:08:02,890 Right. 120 00:08:03,250 --> 00:08:06,770 And I have these items inside the string at ATAC. 121 00:08:07,030 --> 00:08:07,610 OK. 122 00:08:07,810 --> 00:08:11,600 The first item is for example 20 DPI. 123 00:08:11,830 --> 00:08:21,880 The second item is 40 DPI as you can see here for 45 DP 50 DP 55 DP 60 DP 65 DP and 70 DP. 124 00:08:21,880 --> 00:08:24,990 And here I am closing this string at ATAC here. 125 00:08:25,000 --> 00:08:31,150 This is very important that you actually pro-white are a strange strange R8. 126 00:08:31,240 --> 00:08:31,650 OK. 127 00:08:31,720 --> 00:08:38,980 In order to put your items for these values because I want to show to the user a dialog and let them 128 00:08:38,980 --> 00:08:44,920 actually choose one of the radio buttons in order to specify for example a text size for example for 129 00:08:44,920 --> 00:08:47,380 25 dpi or 55 DP. 130 00:08:47,450 --> 00:08:48,100 OK. 131 00:08:48,520 --> 00:08:52,350 And here as you can see I have these streambed at a again here. 132 00:08:52,420 --> 00:08:54,030 I have to string arrows here. 133 00:08:54,190 --> 00:09:02,010 Right staring at it and the name is font sizes values the name of this first string and it is font sizes 134 00:09:02,530 --> 00:09:04,800 and the name of the second string at a. 135 00:09:04,810 --> 00:09:08,230 Here is font size as values. 136 00:09:08,440 --> 00:09:10,440 And again I have these items. 137 00:09:10,600 --> 00:09:14,820 And as you can see I only have these values without the DP here. 138 00:09:15,010 --> 00:09:15,830 OK. 139 00:09:16,090 --> 00:09:20,670 I just put these values number 25 to 40 45 50 55. 140 00:09:20,800 --> 00:09:26,820 So now of an add on our application you'll understand more why we actually created these string address 141 00:09:26,830 --> 00:09:27,450 here. 142 00:09:27,670 --> 00:09:28,100 OK. 143 00:09:28,150 --> 00:09:35,110 For now just know that you need to actually put this here for 25 DP or 40 DP in order to let the user 144 00:09:35,110 --> 00:09:41,050 to select one of these values but the values that are that are going to be shown to the user are going 145 00:09:41,050 --> 00:09:43,000 to be these values. 146 00:09:43,000 --> 00:09:43,370 OK. 147 00:09:43,480 --> 00:09:48,010 So now when then I don't project you can understand what's going on here. 148 00:09:48,040 --> 00:09:51,020 So let's go back to our preferences on the line firelit example. 149 00:09:51,110 --> 00:09:53,840 And now as you can see the arrows are gone at sign. 150 00:09:53,890 --> 00:09:58,990 R.A. size is an added form sizers values isn't going to be the font sizes values. 151 00:09:58,990 --> 00:10:02,190 OK you can put your own font sizes here. 152 00:10:02,200 --> 00:10:10,030 For example number 108 200 300 or whatever values for it you just need to add more items here and here. 153 00:10:10,090 --> 00:10:11,400 OK this is very important. 154 00:10:12,940 --> 00:10:14,000 And now. 155 00:10:14,030 --> 00:10:20,890 So now that I have these values this preference category for my tastes you're number one. 156 00:10:21,020 --> 00:10:27,810 That's actually our go to our main activity that justified here and now let's actually create an intent. 157 00:10:27,860 --> 00:10:33,560 So I want to create an intent and I want to move from this activity to the preferences activity but 158 00:10:33,560 --> 00:10:36,090 we don't have the Prevx friend says activity yet. 159 00:10:36,170 --> 00:10:40,170 So we need to create that preferences activity in our project.
