1 00:00:00,300 --> 00:00:05,500 So as you can see here these are the lines of code that I pasted here. 2 00:00:05,730 --> 00:00:07,330 So we have our method. 3 00:00:07,500 --> 00:00:11,760 And as you can see today the access modifier of this method is private. 4 00:00:11,760 --> 00:00:18,630 The return type of the Smurfette is void and the name of this method is disable cookies spottiness. 5 00:00:18,630 --> 00:00:24,340 So the purpose of this Smurfit is actually to disable the quiz spottiness right. 6 00:00:24,530 --> 00:00:28,050 So as you can see here this method doesn't accept any arguments. 7 00:00:28,110 --> 00:00:33,540 So let's actually go inside the curly braces of the Smurfette And let's see what's going on here. 8 00:00:33,540 --> 00:00:35,390 So as you can see we have a for loop here. 9 00:00:35,400 --> 00:00:36,840 Right. 10 00:00:36,890 --> 00:00:42,680 And this fall of here I actually created of the habit of type integer and the name is row. 11 00:00:42,870 --> 00:00:46,520 And then initially I assigned the value 0 to this rally. 12 00:00:46,980 --> 00:00:53,250 And here I actually created a condition that actually determines how many times this for loop here is 13 00:00:53,250 --> 00:00:54,610 going to be executed. 14 00:00:54,840 --> 00:01:01,110 So until the value of this the row here is actually less than the value of this number of animals gets 15 00:01:01,110 --> 00:01:01,940 grows. 16 00:01:01,950 --> 00:01:08,550 So if I scroll to the top here as you can see inside this classman activity fragment we actually declared 17 00:01:08,790 --> 00:01:09,990 this variable here. 18 00:01:09,990 --> 00:01:11,920 Number of animals guess Rose. 19 00:01:12,060 --> 00:01:12,730 Right. 20 00:01:12,900 --> 00:01:14,550 Which is actually after integer. 21 00:01:14,550 --> 00:01:20,090 So this variable is going to actually hold the number of rows that we have inside our quiz. 22 00:01:20,190 --> 00:01:20,760 Right. 23 00:01:20,760 --> 00:01:22,830 So now let me show you the emulator. 24 00:01:22,830 --> 00:01:28,170 So as you can see here our application is running on the simulator and here as you can see we have a 25 00:01:28,180 --> 00:01:29,760 free guestrooms right. 26 00:01:29,880 --> 00:01:37,050 So this variable here is actually expected to hold the number of animals Jethro's right. 27 00:01:37,080 --> 00:01:39,610 We have free throws and six buttons. 28 00:01:39,940 --> 00:01:44,970 And now if you click on these settings here as you can see we have number of guesses right. 29 00:01:44,970 --> 00:01:52,140 So here we can actually determine that how many buttons that we want to be included in the quiz for 30 00:01:52,140 --> 00:01:52,230 us. 31 00:01:52,290 --> 00:01:53,990 For example for buttons. 32 00:01:54,300 --> 00:01:57,420 And if I click on this back button here at the top as you can see. 33 00:01:57,420 --> 00:02:02,070 Now we have two guests throws right to just rules that actually include that. 34 00:02:02,070 --> 00:02:05,080 Each of them include two buttons. 35 00:02:05,130 --> 00:02:10,260 The first row actually as as you can see here the first row contains two buttons. 36 00:02:10,350 --> 00:02:13,710 And the second row here actually contains two buttons. 37 00:02:13,710 --> 00:02:20,020 So and this variable is deter is actually expected to hold the number of guests. 38 00:02:20,040 --> 00:02:22,500 So here we have to guess rules. 39 00:02:22,560 --> 00:02:26,930 So let's actually scroll down here and now inside the Smurfette. 40 00:02:27,060 --> 00:02:32,910 I actually think I'm saying that until the value of this low value is actually less than the number 41 00:02:32,910 --> 00:02:38,140 of animals gets throws then it's going I to execute this follow up here and here. 42 00:02:38,220 --> 00:02:44,460 And finally here I am actually saying that after each execution of this follow up increment the value 43 00:02:44,460 --> 00:02:47,630 of this roll a variable by one. 44 00:02:47,790 --> 00:02:48,410 OK. 45 00:02:48,570 --> 00:02:52,160 So let's actually go inside is follow up and let's see what's going on here. 46 00:02:52,170 --> 00:02:59,940 First of all in line number 100 an 89 as you can see we have actually our variable of type linear layout 47 00:03:00,540 --> 00:03:07,860 and the name of this rowdier but is just a row linearly out or if it's an assignment operator here and 48 00:03:07,860 --> 00:03:11,660 then here as you can see I am actually referring to the name of this variable. 49 00:03:11,660 --> 00:03:18,950 The rows of guest buttons in animalcules right rows of buttons in animalcules. 50 00:03:18,960 --> 00:03:21,970 So now let's actually scroll to the top here. 51 00:03:22,260 --> 00:03:29,110 As you can see inside this class I actually declare this variable here in line number 51. 52 00:03:29,220 --> 00:03:33,530 As you can see here we have an array of linear layouts here. 53 00:03:33,540 --> 00:03:34,020 Right. 54 00:03:34,050 --> 00:03:39,360 And Arey of linearly outs and then Aimee's rows of spottiness in animal queries. 55 00:03:39,780 --> 00:03:47,360 And here in line I should be in insights uncreate view Mefford we actually initialized this lose of 56 00:03:47,550 --> 00:03:53,670 spottiness valuable sort of rows of spottiness in any Mercuries assignment operator new linearly out 57 00:03:53,820 --> 00:03:54,460 free. 58 00:03:54,720 --> 00:04:01,640 So this is actually is going to hold our free values of type linearly out. 59 00:04:01,650 --> 00:04:05,300 So this is that this is actually the size of this Arey free. 60 00:04:05,730 --> 00:04:09,850 And then here as you can see in lines of 79 flew 81. 61 00:04:10,060 --> 00:04:13,290 He had actually initialising up this at 8. 62 00:04:13,290 --> 00:04:21,030 For example inside as you can see this inside the index zero of this Auret we want to actually put this 63 00:04:21,030 --> 00:04:24,950 value first throw linearly out inciting the x number of one of these already. 64 00:04:25,110 --> 00:04:30,650 We want to assign second rule in linearly out and inside the index number to have this and we want to 65 00:04:30,660 --> 00:04:32,750 assign first row linearly. 66 00:04:32,880 --> 00:04:35,250 So we already initialized this arey. 67 00:04:35,280 --> 00:04:36,110 Right. 68 00:04:36,120 --> 00:04:42,360 So unless I actually scroll down here as you can see here I am saying that rows of just spottiness in 69 00:04:42,470 --> 00:04:48,340 animalcules which is actually an array sup row right. 70 00:04:48,350 --> 00:04:49,610 So for example. 71 00:04:49,730 --> 00:04:51,620 Now let me show you the emulator here. 72 00:04:51,620 --> 00:04:57,770 Let's actually click on the Settings button and number of guesses for example to get this right to number 73 00:04:57,770 --> 00:04:59,420 of actually just options. 74 00:04:59,420 --> 00:05:02,620 If I actually click on Patch button here at the top. 75 00:05:02,690 --> 00:05:06,670 Now as you can see here we have only two buttons and one gets through. 76 00:05:06,800 --> 00:05:08,100 So what does this mean. 77 00:05:08,120 --> 00:05:13,730 This means that here I actually created a full upright and he had this four loops says that until the 78 00:05:13,730 --> 00:05:18,720 value of the stroke which is actually zero is less than number of animals just throws. 79 00:05:18,800 --> 00:05:21,330 So as you can see here we have only one through. 80 00:05:21,330 --> 00:05:23,660 So this value is number one right. 81 00:05:23,690 --> 00:05:25,470 So 0 is less than number one right. 82 00:05:25,490 --> 00:05:28,890 So this follow up here is going to be executed now. 83 00:05:29,110 --> 00:05:38,440 And now here in line number 100 an 89 it we actually created a variable of type linearly out guess linearly 84 00:05:38,450 --> 00:05:39,220 out right. 85 00:05:39,350 --> 00:05:44,010 Assignment operator rows of guess spottiness in animalcules. 86 00:05:44,060 --> 00:05:45,050 So these are 8. 87 00:05:45,080 --> 00:05:51,520 Now actually contains this row here as you can see we have only one row here that contains two buttons 88 00:05:51,530 --> 00:05:52,960 right now. 89 00:05:52,970 --> 00:05:54,590 These are a later. 90 00:05:54,590 --> 00:06:01,160 I'll actually show you here we haven't still puts the lines of code that are related to there actually 91 00:06:01,630 --> 00:06:03,190 are two. 92 00:06:03,620 --> 00:06:12,770 Adding or actually removing rows of buttons rows of just buttons and later I will show you that when 93 00:06:12,800 --> 00:06:14,630 I went they're going to. 94 00:06:14,660 --> 00:06:18,710 And we want to actually for example a change the number of guesses. 95 00:06:18,800 --> 00:06:24,690 But for now just know that here this a is going to hold that that gets through. 96 00:06:24,860 --> 00:06:26,680 So here we have only one guess rule. 97 00:06:27,020 --> 00:06:32,800 And here is Suppe row and this means for example now the value of this low is zero right. 98 00:06:32,840 --> 00:06:37,820 So it's going to go inside this Arey and it's going to actually get a value that is inside of the index 99 00:06:37,820 --> 00:06:38,280 0. 100 00:06:38,330 --> 00:06:43,260 So this row here as you can see is inside the index 0 right. 101 00:06:43,430 --> 00:06:46,370 And it's going to assign that role to this role in your layout. 102 00:06:46,490 --> 00:06:52,030 As you can see here and then here we have another for loop. 103 00:06:52,100 --> 00:06:57,400 So for it bought an index so now we want to actually go inside this classroom here. 104 00:06:57,410 --> 00:07:01,080 And we want to access these buttons inside this linearly out. 105 00:07:01,080 --> 00:07:05,160 So for it but an index assignment operator to zero. 106 00:07:05,540 --> 00:07:12,400 So here we created another variable and we assign the value 0 initially to the spot an index variable. 107 00:07:12,740 --> 00:07:18,510 And then here as you can see we created a condition that actually determines how many times this fall 108 00:07:18,610 --> 00:07:20,590 here is going to be executed. 109 00:07:20,600 --> 00:07:27,320 So until the value of the Spartan index as you can see here is less than the value of this just throw 110 00:07:27,360 --> 00:07:29,140 linearly out as you can see here. 111 00:07:29,150 --> 00:07:31,290 This gets through here right. 112 00:07:31,420 --> 00:07:37,250 Get child count get child count means the children of this linearly out which are actually that is two 113 00:07:37,250 --> 00:07:38,180 buttons right. 114 00:07:38,300 --> 00:07:42,630 These two buttons are actually the children of that linear layout. 115 00:07:42,710 --> 00:07:43,730 Right. 116 00:07:43,730 --> 00:07:53,300 So now as you can see just scroll linearly out that get child count button index plus plus. 117 00:07:53,300 --> 00:07:59,430 So here are they finally you are actually saying that are after effects each execution of this follow 118 00:07:59,420 --> 00:08:01,710 up increment the value of the spot an index. 119 00:08:01,760 --> 00:08:04,520 So the button index Z is 0 right. 120 00:08:04,520 --> 00:08:06,440 So now it's going to actually go inside this loop. 121 00:08:06,500 --> 00:08:08,420 So just throw linearly out. 122 00:08:08,420 --> 00:08:13,200 So here I am referring to this gets through linear layouts that actually holds this linearly out here 123 00:08:13,220 --> 00:08:13,490 right. 124 00:08:13,490 --> 00:08:19,040 This row gets thrown linearly out that get child at. 125 00:08:19,040 --> 00:08:23,270 So it can actually go inside this row get child at bottom index. 126 00:08:23,300 --> 00:08:25,920 So the pattern index is zero right. 127 00:08:26,000 --> 00:08:31,560 So now we can actually get this birth button this button but an index is now 0. 128 00:08:31,790 --> 00:08:38,630 So this button here this actually this birth the button is inside the index 0 of this linear left right 129 00:08:39,020 --> 00:08:42,250 disrobe button index that set enable to false. 130 00:08:42,290 --> 00:08:44,620 So it can actually disable this button. 131 00:08:45,860 --> 00:08:46,840 Right. 132 00:08:46,890 --> 00:08:53,310 And after after executing this for Lapeer is going to try to increment the value of the Spartan index 133 00:08:53,310 --> 00:08:54,060 by Yvonne. 134 00:08:54,120 --> 00:08:56,400 So now the value of what an index is 1. 135 00:08:56,400 --> 00:08:57,130 Right. 136 00:08:57,150 --> 00:09:00,750 So number one is actually less than two. 137 00:09:00,750 --> 00:09:05,110 So as you can see here this row here actually contains two buttons right. 138 00:09:05,190 --> 00:09:11,760 So now button index is actually less than the value of the Get child count of this just rolling out 139 00:09:12,130 --> 00:09:12,910 right. 140 00:09:12,990 --> 00:09:14,440 One is less than two. 141 00:09:14,850 --> 00:09:16,360 And then it's going to again. 142 00:09:16,350 --> 00:09:19,920 It's the cutest thing I've got here it gets through linearly out that child. 143 00:09:19,960 --> 00:09:24,050 But index for about an index now is number one that's set enabled. 144 00:09:24,060 --> 00:09:28,970 So the button here holds is inside the index number one of this row. 145 00:09:29,130 --> 00:09:30,560 So that set enable false. 146 00:09:30,570 --> 00:09:33,710 So it can actually disable this spot in here. 147 00:09:34,020 --> 00:09:38,760 And after that it's going to increment the value of the button indexed by one. 148 00:09:38,760 --> 00:09:41,570 So now the value of this spot an index is two. 149 00:09:41,850 --> 00:09:47,410 And then again it's going to take this condition here so to is not less than the value of this just 150 00:09:47,550 --> 00:09:54,720 linearly out just throw linearly that get child child child because number two is not less than two. 151 00:09:54,720 --> 00:09:57,760 We have two buttons and number two is that is not less than two. 152 00:09:57,870 --> 00:10:00,400 So it's not going to execute this follow up here any more. 153 00:10:00,450 --> 00:10:04,600 As you can see here and it's going to go again to the top here. 154 00:10:04,710 --> 00:10:08,870 It's going to increments the value of this law by what you want. 155 00:10:08,880 --> 00:10:10,500 So here we have only one rule. 156 00:10:10,620 --> 00:10:11,280 OK. 157 00:10:11,400 --> 00:10:15,030 So here now the value of this rule is one. 158 00:10:15,030 --> 00:10:19,050 And number one is not less than number of animals kestrels as you can see here. 159 00:10:19,110 --> 00:10:20,650 We have only one guess through. 160 00:10:20,670 --> 00:10:22,140 So one is not less than one. 161 00:10:22,350 --> 00:10:25,570 And that it's not going to actually execute this for loop here anymore. 162 00:10:25,880 --> 00:10:28,930 And this method here is not going to be executed. 163 00:10:29,160 --> 00:10:35,030 So now as you can see here this is how this effort works in this way we can actually disable our guest 164 00:10:35,090 --> 00:10:36,590 Spartans. 165 00:10:36,630 --> 00:10:43,070 It doesn't really matter that how many good options that we have this method here that we created is 166 00:10:43,070 --> 00:10:45,620 going to actually do that job for us. 167 00:10:45,750 --> 00:10:48,130 So hopefully that makes sense. 168 00:10:48,180 --> 00:10:54,280 And now we need to actually provide another method here as you can see if I scroll to the top here. 169 00:10:54,640 --> 00:10:58,890 Inside this listener we actually provided some of these methods. 170 00:10:58,890 --> 00:11:06,810 For example just get the exact animal name and disable quis guest buttons and we also need to provide 171 00:11:06,860 --> 00:11:11,520 the Smurfette here research animal quiz and animate animal quiz. 172 00:11:11,800 --> 00:11:16,860 So now let's actually create this reset animalcules here inside this class. 173 00:11:16,860 --> 00:11:22,830 So I'm going actually pasting some lines of code here and then I'm going to explain to you what's going 174 00:11:22,830 --> 00:11:23,590 on here.
