1 00:00:00,300 --> 00:00:03,630 So Chase chant 5.40. 2 00:00:03,750 --> 00:00:09,970 So if the value of these fonts string value is chunk $5 or T.F. then it's going to execute this for 3 00:00:09,980 --> 00:00:10,640 loop here. 4 00:00:10,740 --> 00:00:18,170 So for linearly out road and it's going to iterate over the values of this at a loss of just spottiness 5 00:00:18,170 --> 00:00:19,170 in an increase. 6 00:00:19,170 --> 00:00:24,650 So this is actually an area of linearly outs and this for loop here is going to be executed for each 7 00:00:24,650 --> 00:00:26,730 flow that we have. 8 00:00:26,940 --> 00:00:29,860 It is at a loss of just spottiness in animalcules. 9 00:00:29,970 --> 00:00:34,730 So the first row is going to be the room that is inside of the index zero of this at a rate. 10 00:00:35,100 --> 00:00:39,890 And then it's going to actually go and it's going to actually execute this a for loop. 11 00:00:39,990 --> 00:00:44,320 So for it's Cullom and the initial value is zero. 12 00:00:44,520 --> 00:00:50,080 And here we are actually creating a condition that actually determines that how many times this year 13 00:00:50,250 --> 00:00:52,010 is going to be executed. 14 00:00:52,110 --> 00:00:54,780 How many times this fall here is going to be executed. 15 00:00:55,040 --> 00:01:00,900 And here we are saying that after each execution of this loop increment the value of this column by 16 00:01:00,900 --> 00:01:01,700 1. 17 00:01:01,740 --> 00:01:07,620 So an insight does follow up here as you can see actually creating a variable of type button and the 18 00:01:07,620 --> 00:01:10,890 name of this value it is but an assignment operator. 19 00:01:11,120 --> 00:01:14,310 And and here I am actually casting this object to a button object. 20 00:01:14,500 --> 00:01:21,590 And here I am actually getting to the button that is inside of the index zero of this break. 21 00:01:21,660 --> 00:01:24,030 So now let me show you the emulator here. 22 00:01:24,150 --> 00:01:28,220 As you can see this is our emulator and here we have two rows right. 23 00:01:28,350 --> 00:01:34,610 And this means that this at a Rose of just buttons in animal is actually contained these two rows here. 24 00:01:34,620 --> 00:01:35,310 Right. 25 00:01:35,340 --> 00:01:36,030 The first throw. 26 00:01:36,050 --> 00:01:37,510 And this is the second row. 27 00:01:37,650 --> 00:01:41,870 And here we are actually iterating over the values of this at 8. 28 00:01:42,090 --> 00:01:45,010 So the first throw as you can see here is going to be this one. 29 00:01:45,010 --> 00:01:47,040 This first throw here that you can see here. 30 00:01:47,040 --> 00:01:47,840 Right. 31 00:01:47,970 --> 00:01:52,290 And then it's going I should execute this for a loop and it's going to look at the column that is inside 32 00:01:52,290 --> 00:01:54,940 of the index zero of this first throw. 33 00:01:54,990 --> 00:01:58,690 So as you can see here the column zero is this one. 34 00:01:58,710 --> 00:02:01,870 This is the button that is inside of this row. 35 00:02:02,070 --> 00:02:03,970 So this is going to be the column 0. 36 00:02:04,210 --> 00:02:10,500 And now as you can see we are actually when we created this condition we said that this for loop here 37 00:02:10,500 --> 00:02:17,130 is going to be executed until the value of this column here is actually less than the value of the child 38 00:02:17,160 --> 00:02:18,720 count of the stroke. 39 00:02:18,840 --> 00:02:24,070 So the child count of this is to write this row here has two buttons. 40 00:02:24,090 --> 00:02:29,780 So now inside this loop we actually first of all get the button as you can see here that is inside of 41 00:02:29,790 --> 00:02:31,700 this index zero of this row. 42 00:02:31,770 --> 00:02:34,460 So roll that your child at Cullom right. 43 00:02:34,620 --> 00:02:40,950 So for the first time that this group is going to be executed you can see that at the first throw is 44 00:02:40,950 --> 00:02:43,200 going to be as you can see here this one. 45 00:02:43,200 --> 00:02:45,710 And then at the value of this column is 0 right. 46 00:02:45,710 --> 00:02:47,850 So it's going to look at this spot and peacock. 47 00:02:48,030 --> 00:02:50,330 And then as you can see it is actually getting that button. 48 00:02:50,340 --> 00:02:54,750 And it is actually assigning this button to this button valuable right. 49 00:02:54,750 --> 00:02:59,670 So now I am actually calling the Smurfette button that said type face. 50 00:02:59,670 --> 00:03:05,110 So if you are calling the Smurfette on this button and then you are passing the front main activity 51 00:03:05,160 --> 00:03:06,440 or chant 5. 52 00:03:06,480 --> 00:03:10,560 So we actually get these phones from this main activity file inside this class. 53 00:03:10,590 --> 00:03:15,570 We actually first of all declared these phones inside the class as you can see here and VIDEOCLIP these 54 00:03:15,570 --> 00:03:16,890 phones as tatic. 55 00:03:16,920 --> 00:03:17,440 Right. 56 00:03:17,460 --> 00:03:21,860 So we can actually access these phones but actually using the name of this class. 57 00:03:22,020 --> 00:03:27,110 And then inside this class as you can see here I am actually I actually initialized these phones. 58 00:03:27,240 --> 00:03:31,920 So inside this main activity fragment out of a file I can just refer to that form. 59 00:03:31,980 --> 00:03:34,920 And then I can set that typeface to this to this spot. 60 00:03:35,130 --> 00:03:40,540 And in this way I can set this font to my buttons inside my keys. 61 00:03:40,590 --> 00:03:40,970 Right. 62 00:03:41,010 --> 00:03:46,110 So because it is going to actually look at all of the rows and it's going to look at all of the buttons 63 00:03:46,140 --> 00:03:51,700 inside of those rows and it's going to set the typeface to those buttons right. 64 00:03:51,930 --> 00:03:53,370 So hopefully that makes sense. 65 00:03:53,370 --> 00:04:00,180 So in this case when the actually the value of this phone string value is actually chunk five that ETF 66 00:04:00,180 --> 00:04:02,250 is going to execute these lines of code here. 67 00:04:02,400 --> 00:04:05,880 And as you can see here finally they put this statement right. 68 00:04:05,990 --> 00:04:08,120 If we have another case statement. 69 00:04:08,300 --> 00:04:16,110 So Chase if the value of this string value is actually front Larry the T T F then it's going to execute 70 00:04:16,110 --> 00:04:17,340 this for loop here. 71 00:04:17,340 --> 00:04:19,560 So again we have the same for loop here. 72 00:04:19,560 --> 00:04:24,740 So it's going to iterate over the values of these rows of spottiness in animal quiz as you can see here. 73 00:04:25,020 --> 00:04:29,640 And then we have another follow up here the same as the as the one above. 74 00:04:29,790 --> 00:04:35,940 So for in color 0 and this Luby here is going to be executed until the value of this column is less 75 00:04:35,940 --> 00:04:38,470 than the value of the child count of the throw. 76 00:04:38,640 --> 00:04:44,850 And finally here we say that after each execution of this is going to actually increment the value of 77 00:04:44,850 --> 00:04:46,150 this column by one. 78 00:04:46,320 --> 00:04:52,380 And then again we're actually getting the button that is that we have inside this rule as you can see 79 00:04:52,380 --> 00:04:52,850 here. 80 00:04:53,070 --> 00:04:56,860 And then here we are actually calling the cell type face effect on the spot. 81 00:04:57,030 --> 00:05:03,560 And here we are in passing this phone main activity Fauntleroy or brown as you can see here we are actually 82 00:05:03,560 --> 00:05:07,210 passing this font as the argument of the superfit right. 83 00:05:07,340 --> 00:05:13,220 So in case the value of the thing value is actually forth literally but under TGF it's going to execute 84 00:05:13,220 --> 00:05:14,680 these lines of code here. 85 00:05:14,930 --> 00:05:20,900 And finally we put this break statement and here we have our last case statement. 86 00:05:20,960 --> 00:05:27,370 So in case the value of this phone string value rowdier is actually Vondelpark wonder about space. 87 00:05:27,380 --> 00:05:31,700 Space them that ATF then is going to execute this for a loop here. 88 00:05:32,360 --> 00:05:40,070 So for Linnea lay out road and it can actually iterate over the values of this a rows of spottiness 89 00:05:40,070 --> 00:05:41,120 in any milkweeds. 90 00:05:41,330 --> 00:05:48,290 So this fall of here is going to be executed for each row that we have inside is at a loss of just spottiness 91 00:05:48,290 --> 00:05:52,850 in Animal cookies and then it's going to actually go inside the for loop as you can see here we have 92 00:05:52,910 --> 00:05:54,730 another four Lapeer. 93 00:05:54,780 --> 00:05:56,330 So column. 94 00:05:56,600 --> 00:06:01,880 And initially we assign the value zero to this variable and this full repeal is going to be executed 95 00:06:02,000 --> 00:06:08,390 until the value of this column is actually less than the value of the child count of this row. 96 00:06:08,480 --> 00:06:14,660 As you can see here and then it's going to increment the value of this column by one each time. 97 00:06:14,790 --> 00:06:20,930 This is actually executed after each execution of this for loop here is going to increment the value 98 00:06:20,930 --> 00:06:25,190 of this column by one and here again we have actually dispatched in. 99 00:06:25,250 --> 00:06:31,200 So Button button so we have we actually created a variable of type pattern assignment operator. 100 00:06:31,310 --> 00:06:34,480 And then here we are actually casting this object to a button object. 101 00:06:34,520 --> 00:06:39,060 And here we are actually getting there actually column that is inside of this row. 102 00:06:39,080 --> 00:06:45,490 So row that get child add column so it can actually get the specific column that we have inside that. 103 00:06:45,500 --> 00:06:50,870 So for example we have peacocking elephant and this is our actually second row. 104 00:06:50,900 --> 00:06:57,320 So this row is inside the index number one of these A rows of these buttons in animalcules Chad and 105 00:06:57,320 --> 00:06:58,350 Penguin. 106 00:06:58,910 --> 00:07:04,850 And then here we are actually calling this method set type face on the spot in a button that said typeface. 107 00:07:05,000 --> 00:07:09,560 And then we are actually passing this value to the Smurfette main activity that wonder about them. 108 00:07:09,710 --> 00:07:10,710 As you can see here. 109 00:07:10,940 --> 00:07:13,150 And finally we are actually calling display. 110 00:07:13,370 --> 00:07:16,730 Here is this statement at the end of this case statement. 111 00:07:16,850 --> 00:07:20,640 So now this Meffert is actually finished. 112 00:07:20,810 --> 00:07:25,030 Let's actually create another method in order to change the background color. 113 00:07:25,160 --> 00:07:31,310 So here for example if the user wants to go to the settings activity as you can see here they can actually 114 00:07:31,490 --> 00:07:33,360 choose a background color. 115 00:07:33,470 --> 00:07:38,420 And for example they can actually choose the black colors that the bike and color and they can actually 116 00:07:38,420 --> 00:07:39,540 go back here. 117 00:07:39,740 --> 00:07:45,410 And as you can see the back and uncolored is actually black and they can actually guess the name of 118 00:07:45,410 --> 00:07:47,320 the animal as you can see here. 119 00:07:47,330 --> 00:07:48,320 Right. 120 00:07:48,320 --> 00:07:50,790 So hopefully that makes sense. 121 00:07:50,800 --> 00:07:58,080 And now let's actually create a method for that specific job here for that specific logic. 122 00:07:58,310 --> 00:08:04,520 So now I'm going to pasting some lines of code here and then I'm going to explain to you what's going 123 00:08:04,520 --> 00:08:05,280 on here.
