1 00:00:00,450 --> 00:00:04,170 So here we have a like fragment and the name of art. 2 00:00:04,350 --> 00:00:07,320 Like fragment is animal cuius results right. 3 00:00:07,320 --> 00:00:10,250 So now let me show you the emulator as you can see here. 4 00:00:10,260 --> 00:00:16,620 This is our dialogue and here as you can see this is actually a description that let us know about the 5 00:00:16,620 --> 00:00:18,250 results of the quiz. 6 00:00:18,360 --> 00:00:20,480 So now let's go inside this. 7 00:00:20,490 --> 00:00:21,420 They like fragment. 8 00:00:21,440 --> 00:00:23,990 As you can see here we have this method here. 9 00:00:23,990 --> 00:00:26,350 Uncreate dialogue right. 10 00:00:26,370 --> 00:00:30,410 So this is going to be called a venti de-lurk is actually created. 11 00:00:30,810 --> 00:00:37,790 And now as you can see here the return type of this method is dialogue and this it actually accepts 12 00:00:37,810 --> 00:00:42,820 an argument of type Bondel and the name is saved instance state. 13 00:00:42,840 --> 00:00:47,250 So let's go inside the Smurfette And let's see what's going on here in LA. 14 00:00:47,250 --> 00:00:50,130 Number one hundred and fifty two as you can see here. 15 00:00:50,400 --> 00:00:56,460 Here I actually created a builder so alert Stalock that builder and the name Is that right. 16 00:00:56,520 --> 00:01:03,770 New assignment operator new ALLERT de-lurk as you can see here that bill there and here are this bill 17 00:01:03,770 --> 00:01:06,730 that he actually accepts an argument. 18 00:01:06,750 --> 00:01:09,180 So here we need to pass the context. 19 00:01:09,360 --> 00:01:11,890 So the context is going to be good activity. 20 00:01:12,030 --> 00:01:16,920 So this activity method as you can see here does get actually with him if it can actually give us the 21 00:01:16,920 --> 00:01:18,070 context. 22 00:01:18,090 --> 00:01:22,870 So automatically we can actually get the context by actually using this method. 23 00:01:22,920 --> 00:01:23,950 Good activity. 24 00:01:24,240 --> 00:01:29,890 And now we have an object that object a number of one hundred and fifty three. 25 00:01:29,910 --> 00:01:35,000 He had I actually referred to the name of this builder so builder that said message. 26 00:01:35,280 --> 00:01:37,920 So here we need to set a message of this builder. 27 00:01:38,260 --> 00:01:42,770 And now you can see here again I called the Smurfette get strange. 28 00:01:42,990 --> 00:01:46,830 So now let me show you the emulator as you can see here we have this value. 29 00:01:46,900 --> 00:01:49,280 This thing value 10 number of guesses. 30 00:01:49,320 --> 00:01:49,980 Come on. 31 00:01:50,070 --> 00:01:54,240 And one hundred point zero zero percent correct. 32 00:01:54,240 --> 00:01:56,200 So let's think of it. 33 00:01:56,370 --> 00:02:02,630 And now as you can see here for the first argument I need to actually pass this Thring resource value. 34 00:02:02,670 --> 00:02:10,260 So our thoughts throwing darts results underlines Thring underlying value but we haven't actually added 35 00:02:10,310 --> 00:02:13,680 this disvalue to the strength that thinks that exemplified. 36 00:02:13,800 --> 00:02:15,450 So let's copy this name here. 37 00:02:15,450 --> 00:02:19,440 This results the string underlying value here and now. 38 00:02:19,530 --> 00:02:23,310 And now let's actually go inside the strings that exemplify it. 39 00:02:23,700 --> 00:02:30,450 And here let's actually create a string here sort of just open a tag and just type in here strange and 40 00:02:30,450 --> 00:02:32,190 the name is going to be that's valued at. 41 00:02:32,190 --> 00:02:38,520 We're doing that we're actually pasting here results on the length strange underline a value as you 42 00:02:38,520 --> 00:02:39,450 can see here. 43 00:02:39,810 --> 00:02:42,660 And now let's actually close this tack here. 44 00:02:42,900 --> 00:02:47,430 And for the value I'm going to pasting a value here and then I'm going to explain to you what's going 45 00:02:47,430 --> 00:02:48,230 on here. 46 00:02:48,480 --> 00:02:53,580 So as you can see here this is the value that I pasted here inside this attack here. 47 00:02:53,580 --> 00:03:01,140 So for the first argument per cent one dollar sign D as you can see here this is the first argument. 48 00:03:01,140 --> 00:03:04,680 Number of guesses come on. 49 00:03:05,070 --> 00:03:11,820 And as you can see here we have actually a floating a value or the symbol value per cent to a dollar 50 00:03:11,820 --> 00:03:15,990 sign point zero to f percent percent. 51 00:03:15,990 --> 00:03:17,060 So what does this mean. 52 00:03:17,160 --> 00:03:21,780 So this means that here as you can see this person 2 means that this is going to be our second argument 53 00:03:22,230 --> 00:03:23,160 dollar sign here. 54 00:03:23,160 --> 00:03:28,840 Again this is actually a format that when we need to put this dollar sign here in order to specify that 55 00:03:28,850 --> 00:03:32,580 we are going to actually put an integer. 56 00:03:32,580 --> 00:03:39,140 Actually our value may be an integer value or a floating value or this dollar sign here is necessary 57 00:03:39,140 --> 00:03:44,830 you need to put a dollar sign here in order to in order to specify here that this is actually an argument. 58 00:03:44,970 --> 00:03:50,160 So percent to dollar sign means that this is going to be our second argument. 59 00:03:50,160 --> 00:03:55,770 So because here I want to specify of the similar value of floating number. 60 00:03:56,050 --> 00:04:04,170 I actually put this thought here 0 2 so this 0 zero here means that we are going to have two similar 61 00:04:04,170 --> 00:04:07,690 values two values after the decimal digit right. 62 00:04:07,710 --> 00:04:15,480 So 0 2 F again because this is actually a decimal value we need to put this if here as you can see here 63 00:04:15,660 --> 00:04:17,800 because this is actually an integer value. 64 00:04:17,850 --> 00:04:19,230 We put this here. 65 00:04:19,380 --> 00:04:21,620 But here we have a similar value. 66 00:04:21,620 --> 00:04:28,980 If we put f here and here because I want to actually show that to the user the percent character I put 67 00:04:29,160 --> 00:04:31,380 this person's character here twice. 68 00:04:31,620 --> 00:04:37,530 OK so if it if you want to show the person's character with the user you need to put this person's character 69 00:04:37,560 --> 00:04:39,000 twice here right. 70 00:04:39,000 --> 00:04:42,090 So percent percent and it's going I should show it to the user. 71 00:04:42,090 --> 00:04:47,960 The person here as you can see and then as you can see correct I actually put this value here correct. 72 00:04:48,030 --> 00:04:50,790 So 10 for example here 10 number of guesses. 73 00:04:50,790 --> 00:04:51,560 Come on. 74 00:04:51,690 --> 00:04:59,120 And 100 point two of one hundred point zero zero percent correct. 75 00:04:59,130 --> 00:05:01,450 So that makes sense. 76 00:05:01,450 --> 00:05:06,300 And now let's actually go inside this main activity fragment that you have a file here. 77 00:05:06,510 --> 00:05:10,350 So as you can see here Bill there are that. 78 00:05:11,040 --> 00:05:14,630 So I believe that that message as you can see here gets thrown out. 79 00:05:14,700 --> 00:05:15,780 So I call this method. 80 00:05:15,780 --> 00:05:20,970 So for the first argument again I actually referred to that string resource or that string. 81 00:05:20,970 --> 00:05:23,980 That results underlines the value. 82 00:05:24,210 --> 00:05:27,220 Here for the second argument of this gets three Meffert. 83 00:05:27,380 --> 00:05:30,480 You need to specify the number of all guesses. 84 00:05:30,480 --> 00:05:37,230 So as you can see here if I go back inside this string that exemplified it to specify the first argument 85 00:05:37,230 --> 00:05:38,130 right. 86 00:05:38,430 --> 00:05:39,950 One dollar sign. 87 00:05:39,960 --> 00:05:41,790 So this is going to be an integer value. 88 00:05:41,790 --> 00:05:44,310 So let's go back to our main activity fragment out of a file. 89 00:05:44,330 --> 00:05:49,980 So a number of all guesses here is going to be the first argument number of all guesses as you can see 90 00:05:49,980 --> 00:05:52,180 here for example 10 number of cases. 91 00:05:52,590 --> 00:05:58,350 And as you can see here we are actually calculating the percent right here. 92 00:05:58,400 --> 00:06:02,600 We are actually calculating the results so that we can actually show the results to the user. 93 00:06:02,910 --> 00:06:09,210 So inside the Prentice's as you can see I am actually putting I actually put this operation here 1000 94 00:06:09,570 --> 00:06:15,030 divided by and here as you can see I am actually to cast in this number of all guesses as you can see 95 00:06:15,030 --> 00:06:15,640 here. 96 00:06:15,810 --> 00:06:19,800 I am actually casting at this value which is an integer value to a double value. 97 00:06:19,920 --> 00:06:20,160 Right. 98 00:06:20,160 --> 00:06:23,330 So temporarily we have a double value. 99 00:06:23,520 --> 00:06:26,960 We have actually a double version of this value which is actually integer. 100 00:06:26,970 --> 00:06:29,790 So number of all guesses which is now a double. 101 00:06:29,790 --> 00:06:33,580 So 1000 divided by number of all guesses. 102 00:06:33,700 --> 00:06:39,300 So because he had kissed all of the questions right and we had only 10 number of guesses. 103 00:06:39,300 --> 00:06:44,660 So 1000 divided by 10 results in number of 100. 104 00:06:44,670 --> 00:06:45,050 Right. 105 00:06:45,090 --> 00:06:48,900 So because this is actually a double value it gives us a double value. 106 00:06:48,900 --> 00:06:52,530 One hundred point zero zero percent correct. 107 00:06:52,530 --> 00:06:57,780 So this is how we calculate the results and we can actually show that result to the user. 108 00:06:57,870 --> 00:06:59,630 So hopefully that makes sense. 109 00:06:59,970 --> 00:07:03,860 And here as you can see in line number one hundred fifty seven. 110 00:07:03,940 --> 00:07:09,110 Bill there I actually referred to the name of this builder that said positive pot. 111 00:07:09,120 --> 00:07:13,390 And so as you can see here we have a button here reset the animal keys right. 112 00:07:13,410 --> 00:07:17,840 So if you actually click on the spot in here the animal is going to be restarted. 113 00:07:17,850 --> 00:07:22,730 And then we can actually again play with our quiz game. 114 00:07:22,760 --> 00:07:27,000 So Bill there that's a positive button as you can see here. 115 00:07:27,000 --> 00:07:33,640 So for the first argument as you can see I actually specified this are three dots. 116 00:07:33,660 --> 00:07:35,890 Reset animalcules right. 117 00:07:36,090 --> 00:07:43,440 So now let me ask you to show you that if any to actually provide this string the source inside are 118 00:07:43,680 --> 00:07:45,140 strings that exemplified. 119 00:07:45,270 --> 00:07:51,430 So let's actually copy this value here and now let's actually go inside this string that exemplified. 120 00:07:51,560 --> 00:07:54,540 And here let's create a string resource. 121 00:07:54,750 --> 00:07:57,910 So just open a tag and just type in here straight. 122 00:07:58,200 --> 00:08:00,900 And for the name just a paste that's value here. 123 00:08:01,080 --> 00:08:07,530 Reset underline more underline quis right and then close the stack aren't afford the value as you can 124 00:08:07,530 --> 00:08:14,260 see here again just for example typing here restart or just typing reset. 125 00:08:14,460 --> 00:08:19,830 Or you can actually put other values here or I can't just type in reload it doesn't really matter what 126 00:08:19,830 --> 00:08:20,440 you put here. 127 00:08:20,470 --> 00:08:24,390 Restart restart squeeze restart animalcules 128 00:08:27,380 --> 00:08:28,220 right. 129 00:08:28,470 --> 00:08:32,480 And now I can actually go back inside our main activity fragment that of a fight. 130 00:08:32,580 --> 00:08:34,840 And now as you can see here the error is gone. 131 00:08:35,370 --> 00:08:39,770 And here because I want to specify a button for this dialogue as you can see here. 132 00:08:39,900 --> 00:08:45,870 I need to actually first specify devalued the name of the button which is disvalue reset underline animal 133 00:08:45,930 --> 00:08:49,280 Underland quiz for the second argument as you can see here. 134 00:08:49,290 --> 00:08:53,730 I am actually creating our on our listener for that Potten. 135 00:08:53,730 --> 00:08:58,650 So whenever the user touches the spot in here this dialog is going to be notified and it's going to 136 00:08:58,650 --> 00:09:05,010 actually respond according to that are actually not so new dialogue interface. 137 00:09:05,010 --> 00:09:11,090 So because I want to create a listener for this button inside this dialogue we need to create a list. 138 00:09:11,280 --> 00:09:17,220 And unclick listener for this dialogue interface so new they like interface that unclick listener so 139 00:09:17,220 --> 00:09:22,550 it can actually create an anonymous class that actually conforms to this unclick listener interface. 140 00:09:22,800 --> 00:09:25,950 And then it's going to actually over I dismiss it here for us. 141 00:09:25,950 --> 00:09:30,600 So unclick And as you can see here it is unclear if it accepts two arguments. 142 00:09:30,600 --> 00:09:33,280 The first one is the dialogue interface. 143 00:09:33,450 --> 00:09:39,800 Then is dialogue and the second one is actually an integer and its of its name is which. 144 00:09:39,840 --> 00:09:43,470 So it just means that which one is actually selected. 145 00:09:43,470 --> 00:09:46,720 So here it is because we have only one button here. 146 00:09:46,860 --> 00:09:54,030 As you can see when I click on that our application is actually restarted it always is that is reset 147 00:09:54,060 --> 00:09:55,850 and we can actually start over. 148 00:09:56,100 --> 00:10:00,100 So I actually called on my feet here reset animalcules. 149 00:10:00,240 --> 00:10:00,710 Right. 150 00:10:00,840 --> 00:10:06,080 So if any is that it actually touches that spot and dismiss it here is going to be executed. 151 00:10:06,120 --> 00:10:09,570 Reset animalcules but we havent created this method yet. 152 00:10:09,600 --> 00:10:14,370 If you are going to actually create the Smurfette later in our code but for now just put this value 153 00:10:14,370 --> 00:10:14,690 here. 154 00:10:14,700 --> 00:10:23,750 As you can see and now here after this Meffert after this lesson and actually as you can see here you 155 00:10:23,760 --> 00:10:31,430 need to actually turn as you can see need to return value of type dialog from this uncreate dialog Meffert. 156 00:10:31,440 --> 00:10:32,180 Right. 157 00:10:32,190 --> 00:10:35,850 So here I actually return just typing here. 158 00:10:35,870 --> 00:10:38,600 Return builder does create. 159 00:10:38,600 --> 00:10:39,120 Right right. 160 00:10:39,150 --> 00:10:42,680 So it's going to return a value of type dialog. 161 00:10:42,720 --> 00:10:48,360 So it is very important that you put this line of code here before the curly brace of this uncreate 162 00:10:48,510 --> 00:10:57,040 large here and now as you can see at the bottom here you can see that we have this animalcules results. 163 00:10:57,050 --> 00:11:02,910 They like fragments so as you can see after the in curly brace of the Stalock fragment. 164 00:11:02,970 --> 00:11:06,290 Now you need to actually call two other methods here. 165 00:11:06,460 --> 00:11:07,860 Animal Marquise results. 166 00:11:07,860 --> 00:11:09,080 So this is the name of art. 167 00:11:09,140 --> 00:11:12,150 Actually they like fragments right. 168 00:11:12,250 --> 00:11:18,870 Animalcules results that said Transurban cancelable false and this means that for example Lydney actually 169 00:11:19,170 --> 00:11:19,600 does this. 170 00:11:19,600 --> 00:11:23,750 And once again here and there and because I want to actually show you the dialogue again. 171 00:11:24,300 --> 00:11:30,840 So as you can see here this is our dialogue here and now as you can see we can't actually cancel this 172 00:11:30,840 --> 00:11:31,670 dialogue right. 173 00:11:31,680 --> 00:11:38,100 If they actually click on here or here we don't have any options in order to cancel the Stalock we must 174 00:11:38,100 --> 00:11:41,010 actually click on the spot and reset the animalcules. 175 00:11:41,220 --> 00:11:45,390 So that's why I actually put this method here the results. 176 00:11:45,420 --> 00:11:49,250 So these are dialogue that said cancelable false. 177 00:11:49,440 --> 00:11:51,880 And in this way we cannot cancel this dialogue. 178 00:11:51,990 --> 00:11:55,680 The user must click on this button in order to reset the keys. 179 00:11:56,400 --> 00:12:02,540 And in line 151 as you can see here I actually referred to the name of this animal quiz results. 180 00:12:02,540 --> 00:12:04,710 Here again this is our dialogue. 181 00:12:04,990 --> 00:12:05,400 Sure. 182 00:12:05,400 --> 00:12:10,520 So we need to actually call this method show on our animalcules results. 183 00:12:10,560 --> 00:12:13,610 So that is going to actually show this to the user. 184 00:12:13,770 --> 00:12:19,330 So animal quiz results that show and for the measure there should access to argument. 185 00:12:19,350 --> 00:12:24,160 The first one is actually the fragment manager when it was specified the BRAITMAN manager. 186 00:12:24,300 --> 00:12:29,160 So in order to put that value here you can't just simply refer to that to the name of the Smurfette 187 00:12:29,430 --> 00:12:30,660 get fragment manager. 188 00:12:30,660 --> 00:12:36,390 So it's going to automatically give us the fragments manager comma and for the second argument we need 189 00:12:36,390 --> 00:12:37,730 to specify the tack. 190 00:12:37,980 --> 00:12:43,620 So the tag could be any values but I recommend that you actually specify a meaning full value and the 191 00:12:43,620 --> 00:12:44,890 Marquise results. 192 00:12:44,940 --> 00:12:47,280 So this is the tag that we need to specify here. 193 00:12:47,280 --> 00:12:52,300 So as you can see this is actually the osting value and then it's going to show that I like to use it. 194 00:12:52,530 --> 00:12:55,110 And here we have an else statement. 195 00:12:55,110 --> 00:13:01,800 So now as you can see this statement here is really is actually related to this if statement If number 196 00:13:01,800 --> 00:13:06,550 of right answers is equal to number of animals included inquiries. 197 00:13:06,630 --> 00:13:11,240 So if they use that as I should it just all the questions right. 198 00:13:11,560 --> 00:13:14,960 And now we have we have an else statement. 199 00:13:15,030 --> 00:13:18,560 So this means that we haven't seen or finished the quiz. 200 00:13:18,570 --> 00:13:22,920 So if we actually click on these resets the animalcules here is going to reset the quiz for us. 201 00:13:22,920 --> 00:13:27,820 For example now if I actually click on this dark here it's going to wait. 202 00:13:27,880 --> 00:13:31,720 For example one second or two second and it's going to show us the next image. 203 00:13:31,720 --> 00:13:37,070 So if there actually is not actually if there actually a quiz is not finished yet. 204 00:13:37,120 --> 00:13:43,300 If the user needs to for example answer some more other questions inside our quiz then it's going to 205 00:13:43,300 --> 00:13:45,090 execute this statement. 206 00:13:45,370 --> 00:13:51,490 So in other words this if statement here is actually determining whether this quiz is actually finished 207 00:13:51,520 --> 00:13:52,100 or not. 208 00:13:52,140 --> 00:13:52,360 OK. 209 00:13:52,360 --> 00:13:57,520 If the number of right answers is equal to a number of animals included in inquiries then this means 210 00:13:57,520 --> 00:14:02,440 that the quiz is actually finished and that's the time that it's going to actually show that to the 211 00:14:02,440 --> 00:14:04,640 user that you like. 212 00:14:04,840 --> 00:14:10,330 But if the quiz is not finished yet so he's going to actually execute this statement. 213 00:14:10,570 --> 00:14:14,180 And here I actually referred to the name of this handler. 214 00:14:14,230 --> 00:14:19,330 So I actually declared this handler here inside our class as you can see here this is our handler in 215 00:14:19,330 --> 00:14:26,290 line number 44 and we actually initialized this handler inside our uncreate view Meffert handler assignment 216 00:14:26,290 --> 00:14:27,280 operator new handler.
