1 00:00:00,780 --> 00:00:04,480 So now as you can see our application is running on the simulator. 2 00:00:04,620 --> 00:00:11,100 So now I want to actually click on this menu button settings and here as you can see we have some additional 3 00:00:11,160 --> 00:00:12,090 options. 4 00:00:12,090 --> 00:00:13,800 Text Number two settings. 5 00:00:13,800 --> 00:00:17,080 So these are the settings for text number to text view. 6 00:00:17,130 --> 00:00:19,900 So if I actually checked this checkbox here for this form. 7 00:00:19,930 --> 00:00:22,970 Chunk 5 this is another one right. 8 00:00:22,990 --> 00:00:26,450 And now if I click on Patch button here let's see what happens. 9 00:00:26,640 --> 00:00:29,330 And as you can see here nothing happened here. 10 00:00:29,520 --> 00:00:31,060 So there must be a problem. 11 00:00:31,320 --> 00:00:31,810 OK. 12 00:00:32,040 --> 00:00:38,270 So let's actually go back to our Meffert specify the format for takes you to. 13 00:00:38,340 --> 00:00:41,800 There is a problem here and we need to fix that fix that problem. 14 00:00:42,030 --> 00:00:46,200 And as you can see here inside our Meffert specified the font for text view to it there is a problem 15 00:00:46,200 --> 00:00:46,890 here. 16 00:00:46,920 --> 00:00:49,590 THC takes number one and this is wrong. 17 00:00:49,790 --> 00:00:53,990 Finitude said the typeface Forty-Eight it takes number two. 18 00:00:54,130 --> 00:00:57,190 Again we made the same mistake here. 19 00:00:57,270 --> 00:01:04,740 So remember that this sitting here these are the settings these are the checkboxes that are related 20 00:01:04,800 --> 00:01:07,240 only to these takes butu. 21 00:01:07,380 --> 00:01:12,570 So here we need to is actually referred to the name of our text. 22 00:01:12,640 --> 00:01:14,630 It takes number two. 23 00:01:14,910 --> 00:01:18,310 And here again here is the text number two. 24 00:01:18,750 --> 00:01:23,290 So remember THC takes number two THC takes number two and THC takes number two. 25 00:01:23,310 --> 00:01:24,330 Right. 26 00:01:24,330 --> 00:01:29,280 So here we are we are to actually set the typeface for these takes view only. 27 00:01:29,460 --> 00:01:31,280 So let's run our project again. 28 00:01:32,380 --> 00:01:36,370 So this is a common mistakes mistake that are always students make. 29 00:01:36,370 --> 00:01:41,500 And here I wanted to actually show you not to actually make this mistake here. 30 00:01:41,860 --> 00:01:47,170 So as you can see here our application is running on this emulator here and it says and as you can see 31 00:01:47,350 --> 00:01:50,080 the front of our face is now changed. 32 00:01:50,260 --> 00:01:55,390 So if I click on these settings here now you can see these fonts here. 33 00:01:55,480 --> 00:02:01,220 So if I unchecked this checkbox and check the search box here and if I click on back button here. 34 00:02:01,270 --> 00:02:06,170 Now here you can see that the front of this takes view only is changed. 35 00:02:06,340 --> 00:02:12,730 So if I click on the settings again here and now if I actually uncheck this checkbox and check the search 36 00:02:12,730 --> 00:02:16,740 box here for this first form and if I click on back here. 37 00:02:16,870 --> 00:02:20,750 Now as you can see the front of our text view is now changed. 38 00:02:20,770 --> 00:02:21,790 Right. 39 00:02:21,790 --> 00:02:25,150 So let's change this form to the first one. 40 00:02:25,150 --> 00:02:29,270 So let's check this one and check this checkbox here. 41 00:02:29,410 --> 00:02:30,430 So if I click on back. 42 00:02:30,460 --> 00:02:33,940 Now as you can see the front of this takes you is now changed. 43 00:02:33,940 --> 00:02:37,430 So now let's actually put the logic for our fair take takes view. 44 00:02:37,630 --> 00:02:41,400 So let's go back to our preferences underlined find that example here. 45 00:02:41,620 --> 00:02:49,120 After the ending tag of this preference category here I want to I try to add another preference category 46 00:02:49,120 --> 00:02:51,870 here inside our preferred screen. 47 00:02:51,880 --> 00:02:57,100 Remember here we need to add some other lines of code so I'm going to paste in some more lines of code 48 00:02:57,100 --> 00:03:01,220 here and then I'm going to explain explain to you what's going on here. 49 00:03:01,240 --> 00:03:06,180 So as you can see here these are the lines of code that I actually pasted here. 50 00:03:06,220 --> 00:03:12,540 I have another prevents category and the title of this category is text number fli settings. 51 00:03:12,580 --> 00:03:13,150 OK. 52 00:03:13,360 --> 00:03:17,730 And again the first checkbox is this one checkbox for number of. 53 00:03:17,730 --> 00:03:20,110 Fun for text free. 54 00:03:20,110 --> 00:03:24,520 Here we want to actually set the typeface to set the font for our text feel free OK. 55 00:03:24,910 --> 00:03:27,200 And the title again is Cheick chunk 5. 56 00:03:27,220 --> 00:03:29,480 The summary is this is 4 to number one. 57 00:03:29,560 --> 00:03:33,470 And as you can see the default value is this one the name of this font. 58 00:03:33,650 --> 00:03:39,540 And here we are actually ending this checkbox for reference pre-feminist with this ending tag. 59 00:03:40,000 --> 00:03:43,260 And here as you can see we have this checkbox preference again. 60 00:03:43,600 --> 00:03:45,310 And the key is checkbox. 61 00:03:45,340 --> 00:03:48,890 Number two for takes free as you can see here checkbox font. 62 00:03:48,900 --> 00:03:54,710 Number two tastefully the title is Fauntleroy Brown and the summary is. 63 00:03:54,820 --> 00:03:56,750 This is a phone number two. 64 00:03:56,830 --> 00:04:00,580 And here the default value is Fauntleroy Brown here. 65 00:04:00,760 --> 00:04:01,360 OK. 66 00:04:01,750 --> 00:04:06,290 And here we have this checkbox preference again for our first form. 67 00:04:06,370 --> 00:04:12,130 As you can see here checkbox with number of the title is wrong as you can see I don't want to use this 68 00:04:12,130 --> 00:04:12,390 font. 69 00:04:12,390 --> 00:04:16,710 I want to use the word font that I have in my project structure. 70 00:04:16,810 --> 00:04:21,910 So as you can see here in my present structure I don't want to use this one the project. 71 00:04:21,910 --> 00:04:23,540 I just want to use the Android. 72 00:04:23,600 --> 00:04:26,830 OK so just select this section here. 73 00:04:26,830 --> 00:04:29,470 Select it and now select these. 74 00:04:29,540 --> 00:04:32,780 And right now I can see my project structure better. 75 00:04:32,800 --> 00:04:33,560 OK. 76 00:04:34,000 --> 00:04:40,400 And as you can see here inside these assets Walder and inside this directory fonts directed here. 77 00:04:40,630 --> 00:04:41,930 I want to use this one. 78 00:04:41,930 --> 00:04:45,820 This the name of this friend form wunderbar space them. 79 00:04:45,940 --> 00:04:48,920 So I just need to delete this title here. 80 00:04:49,030 --> 00:04:59,460 I just need to delete this a title here and I can just type in vonder bar space or dot or T.F. right. 81 00:04:59,560 --> 00:05:01,590 And the summary is this is for number three. 82 00:05:01,600 --> 00:05:03,880 And again the default value is wrong. 83 00:05:03,910 --> 00:05:13,150 I just need to type Typee wander bar space or dot or T.F.. 84 00:05:13,360 --> 00:05:14,710 Right. 85 00:05:14,710 --> 00:05:21,580 So now as you can see this is our first checkbox preference and here we have these lists pretty France 86 00:05:21,610 --> 00:05:26,030 as you can see here the Andretti's font size takes free. 87 00:05:26,050 --> 00:05:29,930 The total is the size of your phone for free. 88 00:05:30,330 --> 00:05:33,700 And as you can see that the de-lurked title is choose one of the sizes. 89 00:05:33,910 --> 00:05:37,650 So as you can see we have these entries and three values. 90 00:05:37,690 --> 00:05:40,220 And the fourth value is 10 right. 91 00:05:40,270 --> 00:05:46,450 So here we have these little endian tag of this list France which you can actually see which is going 92 00:05:46,450 --> 00:05:51,750 to show us some are radio buttons in order to use one of the sizes. 93 00:05:51,760 --> 00:05:53,790 I'll talk more about this later in this tutorial. 94 00:05:53,800 --> 00:05:57,910 But for now as you can see here we have this preference category. 95 00:05:57,910 --> 00:06:04,370 This is the end in tag of our category for our text free text number of free settings. 96 00:06:04,390 --> 00:06:07,040 So analysis around our project and see what happens. 97 00:06:07,360 --> 00:06:11,120 So here as you can see our application is running on this emulator. 98 00:06:11,320 --> 00:06:14,730 And if I click on this menu button and then click on settings here. 99 00:06:15,010 --> 00:06:21,390 Now we have some other options to take a number of free settings and we have these phones. 100 00:06:21,760 --> 00:06:28,530 And here we have this one is which is going to show us some radio buttons and if we actually check this 101 00:06:28,520 --> 00:06:33,720 check checkbox for this first phone and then click on back here it's not going to change the font of 102 00:06:33,720 --> 00:06:39,350 the stakes because we haven't added the logic in our main activity that were filed yet. 103 00:06:39,450 --> 00:06:39,920 OK. 104 00:06:39,990 --> 00:06:44,560 So here we need to actually create another MFL for our first taste view. 105 00:06:44,610 --> 00:06:45,100 OK. 106 00:06:45,300 --> 00:06:51,290 So after the end in curly brace of this US Meffert here specified the 3:56 takes few to. 107 00:06:51,300 --> 00:06:53,630 We can actually put RMF it here. 108 00:06:53,790 --> 00:06:58,280 So I'm going to pasting some of it here and then I'm going to explain to you what's going on here. 109 00:06:58,380 --> 00:07:03,280 So as you can see here these are the lines of code that I actually pasted here. 110 00:07:03,480 --> 00:07:06,200 Specify the font for Takes view of free. 111 00:07:06,510 --> 00:07:08,510 So now I want to talk about this method. 112 00:07:08,730 --> 00:07:13,190 So as you can see here first of all the access modifier of the Smurfette is public. 113 00:07:13,410 --> 00:07:19,440 The return type of this method is void and the name of this method is specified different for text. 114 00:07:19,440 --> 00:07:20,400 Feel free. 115 00:07:20,580 --> 00:07:22,230 OK this is very important. 116 00:07:22,380 --> 00:07:26,510 And again I declared some boolean valuables inside this method. 117 00:07:26,520 --> 00:07:28,650 The first one is boolean. 118 00:07:28,660 --> 00:07:36,910 Phone number one for text view value Boolean for phone number 2 for text free value as you can see here. 119 00:07:37,470 --> 00:07:41,780 And again Boullion of the phone number free for text free value OK. 120 00:07:41,910 --> 00:07:46,020 So as you can see here we have these values for the number one for text free value. 121 00:07:46,230 --> 00:07:51,010 Phone number two for text revalue and phone number free for text free value. 122 00:07:51,210 --> 00:07:54,140 So I just declare these Boully invaluable. 123 00:07:54,540 --> 00:07:58,910 And here I am just instantiating these boolean variables as you can see here. 124 00:07:59,130 --> 00:08:05,250 So in Duyn one hundred and fifty five hundred forty five as you can see here I am just instantiating 125 00:08:05,280 --> 00:08:11,970 this phone number of one for text for the value but really invaluable assignment operator. 126 00:08:12,180 --> 00:08:19,650 So I refer I refer to the name of this object shared preferences that get boolean checkbox or underlined 127 00:08:19,650 --> 00:08:22,350 font underline number 1 underline takes three. 128 00:08:22,350 --> 00:08:27,000 So this is the key that you want to actually access the value of these. 129 00:08:27,000 --> 00:08:33,810 So let's actually open our emulator and here if I click on menu settings here I want if you want to 130 00:08:33,810 --> 00:08:38,990 actually access the value of this checkbox here tastiness say text number three settings right. 131 00:08:39,060 --> 00:08:44,490 If I want to access this value I need to refer to the key that I actually put inside these preferences 132 00:08:44,520 --> 00:08:49,130 underline for that example here for text number three settings for this category. 133 00:08:49,140 --> 00:08:50,960 As you can see here this is that key. 134 00:08:51,510 --> 00:08:56,590 So it's in our main activity that above right here are the first to the name a name of that key. 135 00:08:56,790 --> 00:08:59,230 And here is the default value for this. 136 00:08:59,700 --> 00:09:06,660 And here I want to instantiate our phone number two for text free value assignment operator again shared 137 00:09:06,660 --> 00:09:08,450 preferences that gets boolean. 138 00:09:08,610 --> 00:09:15,390 So this is the key again checkbox underlined forne underline number to underline text free and the default 139 00:09:15,420 --> 00:09:16,550 value is false. 140 00:09:16,550 --> 00:09:20,120 Again you referred to the name of this boolean variable. 141 00:09:20,200 --> 00:09:26,580 Phone number free for text free value assignment operator shared preferences that get boolean again 142 00:09:26,670 --> 00:09:28,280 is key for the first form. 143 00:09:28,320 --> 00:09:34,080 As you can see here take about Sanderling front underline number three underlined text 3 and the default 144 00:09:34,080 --> 00:09:35,450 value is false. 145 00:09:35,460 --> 00:09:38,310 So here again I have the same if else statements. 146 00:09:38,310 --> 00:09:43,340 So if Fontenot Avant for text free value is actually true. 147 00:09:44,010 --> 00:09:48,190 If the value of this boolean variable is true then it's going to keep this line of code here. 148 00:09:48,290 --> 00:09:53,450 But here I just need to change this name to the text number. 149 00:09:53,450 --> 00:09:54,020 Free. 150 00:09:54,240 --> 00:09:56,840 OK so this is for text view free right. 151 00:09:56,970 --> 00:09:59,260 That's a typeface font number one. 152 00:09:59,520 --> 00:10:04,500 And if this condition here evaluates to false then you can actually execute this else if statement. 153 00:10:04,560 --> 00:10:12,470 So as a phone number two for text free value is true if the user for example checks this second checkbox 154 00:10:12,540 --> 00:10:15,140 here then this checkbox evaluates to TRUE. 155 00:10:15,150 --> 00:10:15,740 Right. 156 00:10:15,780 --> 00:10:20,760 So if that value is true if the value of this boolean variable is true then it's going to execute this 157 00:10:20,760 --> 00:10:21,240 line of code. 158 00:10:21,240 --> 00:10:28,650 Here again I need to change this name to ATX the takes number three that's set so typeface want to number 159 00:10:28,650 --> 00:10:29,420 two. 160 00:10:29,820 --> 00:10:35,930 And again if this condition here evaluates to false I have another LCF statement and as you can see 161 00:10:35,930 --> 00:10:40,070 as if phone number free for text free value is checked. 162 00:10:40,080 --> 00:10:47,580 So if for example they use that uncheck the same box and checks this first 48 for this first checkbox 163 00:10:47,620 --> 00:10:52,280 here this checkbox evaluates the truth value of this checkbox is going to be true. 164 00:10:52,590 --> 00:10:57,970 And then add this of the boolean value of this boolean value but it's going to be true right. 165 00:10:57,990 --> 00:11:04,080 So if this value is true if the value of this phone number of free for text for the value value is true 166 00:11:04,560 --> 00:11:06,300 then it's going to secure this kind of quote here. 167 00:11:06,300 --> 00:11:09,850 So I just need to change this name to the text number three. 168 00:11:09,960 --> 00:11:10,440 OK. 169 00:11:10,560 --> 00:11:13,170 That's a typeface phone number free. 170 00:11:13,420 --> 00:11:17,360 So now let's actually run our project and see what happens.
