1 00:00:00,240 --> 00:00:03,750 OK the specific value that is inside of this specific position. 2 00:00:03,820 --> 00:00:04,430 OK. 3 00:00:04,680 --> 00:00:07,370 So the next method is get an ID ID. 4 00:00:07,410 --> 00:00:14,030 So as you can see here are the return type of this method is long and the name of this method is gets 5 00:00:14,080 --> 00:00:19,450 either an ID and if it actually accepts an argument of type position as you can see here. 6 00:00:19,570 --> 00:00:29,250 So the item id of our objects would be that the position of our values inside of our arms for example 7 00:00:29,250 --> 00:00:34,740 this animal images array for example at the position of this value as you can see here is zero. 8 00:00:34,740 --> 00:00:35,190 OK. 9 00:00:35,340 --> 00:00:37,460 So this would be the item ID. 10 00:00:37,530 --> 00:00:37,960 OK. 11 00:00:38,100 --> 00:00:41,910 So I can just return this position here. 12 00:00:42,120 --> 00:00:46,940 OK and as you can see here we have good view of it. 13 00:00:46,950 --> 00:00:53,270 So this effort is going to be called up on every iteration of our values inside of the literalist view 14 00:00:53,280 --> 00:00:53,780 OK. 15 00:00:53,910 --> 00:01:00,090 Whenever we actually scroll down or up or dismiss this if it is going to be called in order to actually 16 00:01:00,840 --> 00:01:05,040 put our objects and values to the list the list view. 17 00:01:05,040 --> 00:01:05,400 OK. 18 00:01:05,400 --> 00:01:07,300 So this is very important. 19 00:01:07,440 --> 00:01:12,660 And as you can see it isn't if it actually returns a value of type view and the name of this and if 20 00:01:12,660 --> 00:01:13,630 it is good view. 21 00:01:13,770 --> 00:01:14,430 OK. 22 00:01:14,760 --> 00:01:20,820 And as you can see this in fact accepts the arguments the first argument is in position the position 23 00:01:20,850 --> 00:01:23,910 of objects inside of the list view. 24 00:01:24,030 --> 00:01:24,530 OK. 25 00:01:24,780 --> 00:01:29,230 And this of you as you can see here this is another argument kind of interview. 26 00:01:29,250 --> 00:01:33,320 So just change the name of this argument to view. 27 00:01:33,670 --> 00:01:39,760 OK so this argument is the view of objects in the list view. 28 00:01:39,840 --> 00:01:40,380 OK. 29 00:01:40,620 --> 00:01:44,360 And we have a view Group parent OK. 30 00:01:44,880 --> 00:01:47,720 And this would be for example the list itself. 31 00:01:47,760 --> 00:01:48,700 OK. 32 00:01:49,380 --> 00:01:54,540 Now let's actually delete this line of quote here and then we're going to actually put in our own implementations 33 00:01:54,870 --> 00:01:56,710 inside of the Smurfette here. 34 00:01:56,790 --> 00:02:02,010 So now I'm going to actually paste in some lines of code here inside of this method and then I'm going 35 00:02:02,010 --> 00:02:03,550 to explain to you what's going on here. 36 00:02:03,600 --> 00:02:08,860 So as you can see here these are the lines of code that you actually paste that here inside of this 37 00:02:09,210 --> 00:02:09,930 view Smurfette. 38 00:02:09,990 --> 00:02:10,570 OK. 39 00:02:10,860 --> 00:02:18,900 First of all in line 57 as you can see here I actually try to assign a value to this view object that 40 00:02:18,900 --> 00:02:22,630 we actually receive as an argument from the same if it gets V. 41 00:02:22,680 --> 00:02:23,280 OK. 42 00:02:23,400 --> 00:02:28,490 So I just referred to the name of this argument view assignment operator. 43 00:02:28,680 --> 00:02:34,980 And then I actually have referred to this layout inflator object that I actually declared in line 17 44 00:02:35,100 --> 00:02:38,600 in in our customized view class. 45 00:02:38,600 --> 00:02:45,590 And as you can see here inside of this constructor of this customized this view class I actually instantiated 46 00:02:45,600 --> 00:02:46,230 this object. 47 00:02:46,230 --> 00:02:46,840 OK. 48 00:02:47,220 --> 00:02:52,220 So as you can see here I referred to the name of that object out inflator dot. 49 00:02:52,410 --> 00:02:55,990 And here I am actually calling this inflates Mefford on this object. 50 00:02:56,010 --> 00:02:56,730 OK. 51 00:02:57,300 --> 00:02:59,840 And this MF it actually exits to arguments. 52 00:03:00,030 --> 00:03:04,750 The first argument is actually the customize the list view. 53 00:03:04,770 --> 00:03:10,620 OK we need to put our own customized list view that we actually created in our project. 54 00:03:10,630 --> 00:03:14,050 OK so this is our customized this view that XML file. 55 00:03:14,280 --> 00:03:21,210 So for the first argument I needed to assign that value here or that layout that customized this view 56 00:03:21,210 --> 00:03:21,790 OK. 57 00:03:22,050 --> 00:03:24,920 And it's like such an argument is of for The Root. 58 00:03:25,050 --> 00:03:28,380 So we don't need that value here. 59 00:03:28,380 --> 00:03:33,770 So I just nod here and here as you can see in line 59. 60 00:03:34,230 --> 00:03:38,680 I actually created an object of type image view. 61 00:03:38,880 --> 00:03:41,650 So the name of this image is our empty animal. 62 00:03:41,760 --> 00:03:42,240 OK. 63 00:03:42,450 --> 00:03:48,180 As you can see here in our customized underline list underlined view that image here as you can see 64 00:03:48,180 --> 00:03:52,780 this is our image view and the idea of this image is I m g. 65 00:03:52,830 --> 00:03:53,560 OK. 66 00:03:54,000 --> 00:04:00,990 And here I assigned the value I am the animal for the name of my image view assignment operator and 67 00:04:00,990 --> 00:04:06,540 as you can see here I am actually casting this object to art to an image view object. 68 00:04:06,540 --> 00:04:10,230 And here as you can see I referred to the name of this view here. 69 00:04:10,230 --> 00:04:10,690 OK. 70 00:04:10,860 --> 00:04:17,310 So this view actually has this customized underline list underline view inside it. 71 00:04:17,310 --> 00:04:17,880 OK. 72 00:04:17,880 --> 00:04:24,210 So I needed to actually first to this view here in order to access these components inside of these 73 00:04:24,420 --> 00:04:25,840 customized to this view here. 74 00:04:25,860 --> 00:04:26,660 OK. 75 00:04:27,060 --> 00:04:34,440 And here I refer to this view here Dot find the view by ID or that ID that I enjoy. 76 00:04:34,830 --> 00:04:36,280 And I do the same here. 77 00:04:36,530 --> 00:04:40,900 I actually declared this takes view as final. 78 00:04:41,340 --> 00:04:41,910 OK. 79 00:04:42,240 --> 00:04:46,880 And as you know final means that this object is actually constant. 80 00:04:47,040 --> 00:04:47,760 OK. 81 00:04:48,180 --> 00:04:54,930 And as you can see type of My object is a text view the name of my object is the animal name assignment 82 00:04:54,960 --> 00:05:02,970 operator and then here I actually cast this object to our text view object view that find view by ID 83 00:05:03,030 --> 00:05:06,330 or thought Id taught the animal name. 84 00:05:06,660 --> 00:05:12,900 And I did the same job here takes few takes the animal power and then I actually cast the object to 85 00:05:12,900 --> 00:05:20,280 a text view object view that find view by ID or the idea that the animal power as you can see here. 86 00:05:20,490 --> 00:05:26,610 So if we have to use the animal name and we have to use the animal power here and here as you can see 87 00:05:26,670 --> 00:05:36,150 we have the animal speed view find view by id our ID that the animal speed and here I actually created 88 00:05:36,390 --> 00:05:38,240 to String objects OK. 89 00:05:38,400 --> 00:05:40,650 Stream all the animal power. 90 00:05:40,840 --> 00:05:41,360 OK. 91 00:05:41,610 --> 00:05:46,200 As you can see here the unempowered that gettext that Stream. 92 00:05:46,540 --> 00:05:53,950 And I actually created another string object that old RTX the animal speed the animal speed that get 93 00:05:54,180 --> 00:05:55,430 text that was strange. 94 00:05:55,500 --> 00:06:02,080 OK so now I want to actually output some images to the image views on the screen. 95 00:06:02,080 --> 00:06:05,260 OK so as you can see here these are the addresses of our images. 96 00:06:05,260 --> 00:06:05,770 OK. 97 00:06:06,070 --> 00:06:07,380 So here are. 98 00:06:07,690 --> 00:06:15,070 I just need to refer to the name of these are UMG animals that set image resource. 99 00:06:15,310 --> 00:06:15,960 OK. 100 00:06:16,450 --> 00:06:22,990 And here as you can see this if it actually accepts as you can see at say enjoyable resource this refers 101 00:06:23,230 --> 00:06:26,880 to the triable folder ain't there ID as you can see here. 102 00:06:27,180 --> 00:06:27,740 OK. 103 00:06:27,970 --> 00:06:36,910 So here I need to actually refer to the rest ID resources ID of my images inside the tribal folder. 104 00:06:36,910 --> 00:06:37,570 OK. 105 00:06:37,570 --> 00:06:40,780 So these are the addresses that are inside of this animal images. 106 00:06:40,810 --> 00:06:47,170 So I can't just refer to the name of that every animal images Suppe position. 107 00:06:47,800 --> 00:06:52,780 So as you can see here we have this position as an argument to disprove it and we can use this position 108 00:06:52,900 --> 00:06:53,960 here in RMF. 109 00:06:54,010 --> 00:06:59,520 So as you can see here I just referred to this opposition here that we see as an argument. 110 00:06:59,740 --> 00:07:06,580 So this position knows of the specific value that is inside of that specific position of this tree. 111 00:07:06,760 --> 00:07:12,760 So if we could just refer to that position and here we can actually access this specific image that 112 00:07:12,760 --> 00:07:16,050 is inside of this specific position of these Adli. 113 00:07:16,070 --> 00:07:22,920 OK so now let's actually go back and say this main activity double file here. 114 00:07:22,930 --> 00:07:28,960 Now let's actually create an object from these customized list view class here. 115 00:07:29,200 --> 00:07:32,840 So I just need to refer to the name of this class customize the list view. 116 00:07:33,240 --> 00:07:37,860 And I would prefer to name this object adapter. 117 00:07:38,100 --> 00:07:38,410 OK. 118 00:07:38,410 --> 00:07:44,300 Because as you can see this customized to this view extends base adapter class. 119 00:07:44,320 --> 00:07:48,010 OK so there is and is our relationship between these two classes. 120 00:07:48,010 --> 00:07:48,520 OK. 121 00:07:48,790 --> 00:07:54,870 So I can call the object that I actually create from this customize this view as adapter. 122 00:07:54,960 --> 00:07:55,220 OK. 123 00:07:55,240 --> 00:07:59,410 Assignment operator and then I just put in the new convert. 124 00:07:59,560 --> 00:08:04,150 And here again I referred to the name of this customized and this view class. 125 00:08:04,150 --> 00:08:10,600 So as you can see here are the constructor of this class actually accepts a value of type context as 126 00:08:10,600 --> 00:08:11,900 you can see here. 127 00:08:11,990 --> 00:08:15,200 And we created the constructor of this class. 128 00:08:15,240 --> 00:08:21,340 You specify that this class actually sets an argument of that context. 129 00:08:21,430 --> 00:08:29,020 And here we initialized this context of valuable instance value but that we created inside of this class 130 00:08:29,680 --> 00:08:35,220 and then we initialized this layout inflator object that we created inside of this class. 131 00:08:35,320 --> 00:08:35,890 OK. 132 00:08:36,220 --> 00:08:43,190 So here I just need to put in a context so the context would be this class. 133 00:08:43,210 --> 00:08:44,580 Ok main activity class. 134 00:08:44,650 --> 00:08:51,280 So I can just type in main activity that this and then I need to put in the semicolon at the end of 135 00:08:51,280 --> 00:08:52,460 my statement. 136 00:08:52,930 --> 00:08:57,110 So as you can see if you have an adapter here and we have also a list view. 137 00:08:57,130 --> 00:09:00,860 OK that is inside of this content underline mean that example. 138 00:09:00,880 --> 00:09:08,650 So now I want to actually inflate these or customize the list view here that we created on these content 139 00:09:08,680 --> 00:09:10,870 underline mean that segment on this list view here. 140 00:09:10,900 --> 00:09:11,370 OK. 141 00:09:11,530 --> 00:09:19,480 So in order to do that I can just type in LSD list and it's the view that set adapter. 142 00:09:20,050 --> 00:09:20,790 OK. 143 00:09:20,950 --> 00:09:26,740 And here we need to putting the adapter inside of this Apprentice's so I can just refer to the name 144 00:09:26,740 --> 00:09:34,900 of this adapter object as you can see here and it's done both but you have an arrow inside of this customized 145 00:09:34,960 --> 00:09:37,030 at view that job offer it here. 146 00:09:37,390 --> 00:09:44,260 As you can see here inside of these gates view it as you can see of you needed to actually return an 147 00:09:44,260 --> 00:09:45,860 object of type view. 148 00:09:46,030 --> 00:09:47,160 As you can see here it is. 149 00:09:47,170 --> 00:09:51,630 And if it actually returns a value of view so I can just return to that view here. 150 00:09:51,730 --> 00:09:52,150 OK. 151 00:09:52,300 --> 00:09:57,700 The view that we receive as an argument and as you can see in line 57 I assigned this value to that 152 00:09:58,000 --> 00:09:58,850 of you object. 153 00:09:58,870 --> 00:09:59,370 OK. 154 00:09:59,380 --> 00:10:01,660 Lay out inflators that inflate. 155 00:10:01,660 --> 00:10:03,660 These are customized to this view. 156 00:10:03,700 --> 00:10:04,340 OK. 157 00:10:04,660 --> 00:10:07,290 And as you can see the second argument is not OK. 158 00:10:07,510 --> 00:10:10,840 And then we assign that value to this object. 159 00:10:10,930 --> 00:10:15,490 And here I can just pretend that value return view semi-colon.
