1 00:00:00,270 --> 00:00:06,570 So here as you can see our application is running on the simulator but now I want to actually create 2 00:00:06,630 --> 00:00:09,890 a menu for my application here inside this action. 3 00:00:09,910 --> 00:00:11,660 But I want to create a menu. 4 00:00:12,030 --> 00:00:19,080 So now in my project structure here I need to actually click on these raids folder here. 5 00:00:19,320 --> 00:00:20,390 Right click on it. 6 00:00:21,390 --> 00:00:27,700 And then click on Android early source directory as you can see here. 7 00:00:27,710 --> 00:00:34,710 Android resource directory and for the name just type in here just for the resource type just select 8 00:00:34,920 --> 00:00:40,280 menu OK and then click on OK as you can see the directory name is menu. 9 00:00:40,410 --> 00:00:44,660 There is sort of the resource type menu and the source said is me OK. 10 00:00:44,760 --> 00:00:47,030 And then click on OK here. 11 00:00:47,100 --> 00:00:53,850 So as you can see here I have this menu of folder this our menu directory inside my race for that right. 12 00:00:53,910 --> 00:00:57,360 So just right click on these menu here. 13 00:00:57,570 --> 00:00:58,320 And a new. 14 00:00:58,360 --> 00:01:01,160 And then click on menu resource file. 15 00:01:01,500 --> 00:01:10,530 So just for the name of our menu file which is going to be an XML file just type in here menu underly 16 00:01:10,610 --> 00:01:11,220 made. 17 00:01:11,580 --> 00:01:13,230 And then click on OK. 18 00:01:13,650 --> 00:01:19,170 So inside this menu directory I have this menu underline the XML file here. 19 00:01:19,230 --> 00:01:21,250 So as you can see here this is that file. 20 00:01:21,480 --> 00:01:24,220 So now I want to actually create an item. 21 00:01:24,360 --> 00:01:33,780 So just open a type here item and for the title just type in here settings and then I want to actually 22 00:01:33,780 --> 00:01:35,430 give an ID to this item. 23 00:01:35,430 --> 00:01:41,850 So just type in here ID as you can see here and then press enter key to select this idea here. 24 00:01:42,090 --> 00:01:48,720 And in order to create an ID unit to actually used this here at sign Plus Id This is very important 25 00:01:48,990 --> 00:01:49,470 at sign. 26 00:01:49,470 --> 00:01:53,840 Plus Id just use this piece of code here and then press that into the general keyboard. 27 00:01:54,060 --> 00:01:58,710 So now I can actually specify an ID for my item here. 28 00:01:58,800 --> 00:02:08,080 So for the ID just type in here settings OK and then now let's actually close this item here by just 29 00:02:08,140 --> 00:02:10,790 using a closing tag here. 30 00:02:10,840 --> 00:02:14,440 Now let's run our project and see what happens. 31 00:02:14,470 --> 00:02:20,790 So as you can see here now our application is running on the simulator and still we can't see this the 32 00:02:20,830 --> 00:02:22,420 item menu here. 33 00:02:22,570 --> 00:02:23,050 OK. 34 00:02:23,170 --> 00:02:27,700 So we need to go back inside our main activity the java file here and we need to actually overwrite 35 00:02:27,700 --> 00:02:28,850 some methods. 36 00:02:28,900 --> 00:02:34,990 The first one is on create options menu. 37 00:02:35,440 --> 00:02:37,230 And as you can see here we have this method. 38 00:02:37,240 --> 00:02:42,270 So the autocomplete feature of the Android studio is helping me to find Mefford. 39 00:02:42,420 --> 00:02:45,700 So just a selected and then person enter key on your keyboard. 40 00:02:46,060 --> 00:02:51,790 So as you can see here this is that Meffert and the second half of any two over right here is actually 41 00:02:51,880 --> 00:02:58,740 an options item selected as you can see here just select it and press on entelechy on your keyboard. 42 00:02:58,840 --> 00:03:04,810 So now inside this uncreate options menu Meffert as you can see we have this line of code here. 43 00:03:04,810 --> 00:03:08,140 Just select this line of code and then press until it key on your keyboard. 44 00:03:08,290 --> 00:03:11,480 So now I want to actually put in my own logic here. 45 00:03:11,710 --> 00:03:19,000 So now I want to actually inflate the menu on my action but so as you can see here in our emulator we 46 00:03:19,000 --> 00:03:19,650 have this action. 47 00:03:19,660 --> 00:03:23,830 But here and I want to actually inflate the menu on this action but here. 48 00:03:24,000 --> 00:03:32,230 So in order to do that I can just type in here get menu inflator does inflate and here you need to actually 49 00:03:32,230 --> 00:03:33,740 pass two arguments. 50 00:03:33,880 --> 00:03:36,450 The first one is of type menu resource file. 51 00:03:36,610 --> 00:03:41,980 So as you can see here we have this our menu resource file here in our project structure inside this 52 00:03:42,150 --> 00:03:45,180 race folder menu that underline minute example. 53 00:03:45,280 --> 00:03:52,960 So here I can just type in our start menu that menu underline main here and then press on Enter key 54 00:03:52,960 --> 00:03:53,760 on your keyboard. 55 00:03:53,890 --> 00:03:55,560 So this is the first argument. 56 00:03:55,690 --> 00:04:01,510 The second one is the menu object that you actually receive as an argument from this on create options 57 00:04:01,510 --> 00:04:02,400 menu method. 58 00:04:02,560 --> 00:04:04,890 So here I can just type in menu. 59 00:04:05,620 --> 00:04:12,700 So now because this if it actually returns a boolean value we need to return true in order to inflate 60 00:04:12,700 --> 00:04:15,230 this menu here on our action bar. 61 00:04:15,280 --> 00:04:21,070 So here I can just type in return true and then put a semicolon at the end of your statement. 62 00:04:21,070 --> 00:04:24,700 So now let's actually run our project and see what happens. 63 00:04:24,700 --> 00:04:30,920 So as you can see here now our application is running on this emulator here and here at the top. 64 00:04:30,950 --> 00:04:33,700 Inside this action but here we can see this menu. 65 00:04:33,790 --> 00:04:36,810 And if I selected I can see the settings here. 66 00:04:36,960 --> 00:04:37,610 OK. 67 00:04:37,720 --> 00:04:43,430 So this is the item that they actually created inside this menu and the line made that examine the title 68 00:04:43,430 --> 00:04:46,420 the settings and the ID's settings right. 69 00:04:46,420 --> 00:04:49,820 So let's go back into our main activity Dodgeville file here. 70 00:04:50,050 --> 00:04:52,480 And I want to actually do something. 71 00:04:52,660 --> 00:04:55,340 When the user clicks on these settings here. 72 00:04:55,450 --> 00:04:56,260 OK. 73 00:04:56,260 --> 00:05:02,990 So again let's actually go inside this on options item selected here and here as you can see this before 74 00:05:02,990 --> 00:05:05,080 it again returns a boolean value. 75 00:05:05,200 --> 00:05:11,080 So it is actually enough to really turn the supervision of the Smurfette superdad on options item selected 76 00:05:11,140 --> 00:05:11,490 item. 77 00:05:11,530 --> 00:05:12,080 OK. 78 00:05:12,220 --> 00:05:16,300 So now before this line of code here we can put our own logic here. 79 00:05:16,330 --> 00:05:21,370 First of all I want to actually get the ID of the item that you've selected. 80 00:05:21,370 --> 00:05:26,590 So inside this menu under the nine minute segment as you can see I have this item and I actually provided 81 00:05:26,620 --> 00:05:29,080 an ID for this item sitting right. 82 00:05:29,080 --> 00:05:31,690 So here inside is an options item selected. 83 00:05:31,690 --> 00:05:33,260 I can get that ID. 84 00:05:33,280 --> 00:05:39,460 So in order to get the ID I can create an entire idea about it and the name of my value is going to 85 00:05:39,460 --> 00:05:40,190 be ID. 86 00:05:40,330 --> 00:05:41,660 Assignment operator. 87 00:05:41,770 --> 00:05:44,530 So as you can see here we actually received this item. 88 00:05:44,590 --> 00:05:48,670 This menu item as an argument from an optional item selected Nefert. 89 00:05:48,670 --> 00:05:55,700 So I can just refer to the name of this argument item that gets item ID. 90 00:05:55,720 --> 00:05:59,460 So now I can actually access the ID of my item. 91 00:05:59,530 --> 00:06:00,160 OK. 92 00:06:00,160 --> 00:06:05,360 So here I can actually create an if statement or actually a switch statement. 93 00:06:05,560 --> 00:06:12,220 And here I can switch between the IDs of the items that are inside of this menu that menu that main 94 00:06:12,730 --> 00:06:17,760 menu and the alignment that means that example as you can see here we have only one item here. 95 00:06:18,280 --> 00:06:22,830 And the 80s settings so I can just type in switch ID. 96 00:06:23,370 --> 00:06:24,110 OK. 97 00:06:24,130 --> 00:06:29,650 And then I need to open and close this switch block here and then I can create an ok statement. 98 00:06:29,760 --> 00:06:37,720 Case r that I'd already thought settings as you can see here just select it and then person enter key 99 00:06:37,780 --> 00:06:44,070 on your keyboard and then put a colon here and then create a break statement here. 100 00:06:44,320 --> 00:06:51,800 So now for this break case statement I can't say that I can actually create an intent object here. 101 00:06:51,850 --> 00:07:00,010 So what I want to do I want to actually move from this activity to the preferences example that I am 102 00:07:00,130 --> 00:07:01,150 going to create. 103 00:07:01,160 --> 00:07:07,410 Now first of all let's actually create that example of file and then we're going to actually continue 104 00:07:07,720 --> 00:07:10,150 coding inside this case statement. 105 00:07:10,160 --> 00:07:17,940 So now in our project structure let's actually select this arrays folder here as you can see right click 106 00:07:17,940 --> 00:07:22,890 on it and then click on new and then click on Android resource wide. 107 00:07:23,070 --> 00:07:23,880 OK. 108 00:07:24,300 --> 00:07:33,470 And for the name of our file just type in here pretty for preferences underline file that exit mail. 109 00:07:33,810 --> 00:07:34,420 OK. 110 00:07:34,710 --> 00:07:43,080 And the resource type just type in Excel like this XML here for the resource type and the root element 111 00:07:43,080 --> 00:07:49,160 is going to be pretty friends screen and the source said is main and the directory name is XML. 112 00:07:49,590 --> 00:07:50,220 OK. 113 00:07:50,610 --> 00:07:56,490 So it's going to actually create a directory for us and then it's going to actually also create this 114 00:07:56,670 --> 00:07:57,300 XML file. 115 00:07:57,300 --> 00:07:59,470 Preferences underline find that example. 116 00:07:59,660 --> 00:08:01,960 OK so let's click on OK here. 117 00:08:02,870 --> 00:08:06,740 An insight Isarel falter I have this XML directory. 118 00:08:06,800 --> 00:08:10,050 As you can see an insight is ASML directory. 119 00:08:10,070 --> 00:08:14,470 I have these preferences underlined file that ASML here. 120 00:08:14,600 --> 00:08:19,780 OK so now let's to go inside these preferences underline find that example here. 121 00:08:20,030 --> 00:08:23,200 And now let's actually put some lines of code here. 122 00:08:23,510 --> 00:08:28,670 So this is going to be the settings activity the settings a layout of our application. 123 00:08:28,670 --> 00:08:33,830 So when the user clicks on these settings here as you can see when the user clicks on the settings here 124 00:08:34,080 --> 00:08:40,850 is they're going to actually go to this XML file and then they can actually interact with that XML file 125 00:08:41,090 --> 00:08:46,480 and specify some actually preferences for their application for the application. 126 00:08:46,490 --> 00:08:47,320 Right. 127 00:08:47,450 --> 00:08:53,630 So now I went actually pasting some lines of code here and then I'm going to explain to you what's going 128 00:08:53,630 --> 00:08:54,490 on here. 129 00:08:54,770 --> 00:09:03,350 So now as you can see here these are the lines of code that I actually pasted here inside these preferences 130 00:09:03,630 --> 00:09:10,280 underline file that example he had as you can see inside these preferences preferences are preference. 131 00:09:10,280 --> 00:09:16,040 Screen tag here as you can see I have this preference category here as you can see. 132 00:09:16,220 --> 00:09:17,770 So I have these lines of code. 133 00:09:17,840 --> 00:09:21,550 So now I'm gonna actually explain to you what's going on here. 134 00:09:22,100 --> 00:09:28,930 As you can see here in line 6 as you can see I created this tag here preference category. 135 00:09:29,390 --> 00:09:31,890 And I gave a title to this category. 136 00:09:32,120 --> 00:09:36,120 And as you can see here the title is text number 1 settings. 137 00:09:36,140 --> 00:09:36,650 OK. 138 00:09:36,830 --> 00:09:40,700 So here I want to specify the settings for the text number of on. 139 00:09:40,880 --> 00:09:45,160 So as you can see here in our emulator I have this takes number one here. 140 00:09:45,200 --> 00:09:45,890 OK. 141 00:09:45,890 --> 00:09:52,170 So as you can see I have these settings and I want to provide some settings for this text number one. 142 00:09:52,400 --> 00:09:54,860 So let's see what that is going to be the settings. 143 00:09:54,890 --> 00:09:59,530 The first item as you can see here inside this preference category here. 144 00:09:59,660 --> 00:10:06,100 I have this checkbox preference so I'm going to actually create a checkbox for this. 145 00:10:06,370 --> 00:10:08,790 Takes one here checkbox preference. 146 00:10:08,960 --> 00:10:14,940 And as you can see here these are the attributes that they actually assigned for this checkbox preference. 147 00:10:14,960 --> 00:10:20,270 So first of all I actually gave a key to this checkbox preference. 148 00:10:20,310 --> 00:10:22,930 The keys checkbox underline font. 149 00:10:22,960 --> 00:10:25,240 The line number of underlined text 1. 150 00:10:25,490 --> 00:10:32,360 So now you can actually understand that you want to actually specify the font for my text one here. 151 00:10:32,640 --> 00:10:33,440 OK. 152 00:10:33,650 --> 00:10:40,390 When I go into the settings XML file I want to specify the font of this text one here for example. 153 00:10:40,580 --> 00:10:42,180 So this is going to be the key. 154 00:10:42,200 --> 00:10:51,840 So help us to actually this helps us to use this key in our Java file and interact with this checkbox 155 00:10:51,870 --> 00:10:52,630 preference. 156 00:10:52,760 --> 00:10:57,660 So this is very important that you actually give a key to your checkbox preference. 157 00:10:58,040 --> 00:11:05,160 And here I gave a title to my a checkbox free France and the title is traunch 5. 158 00:11:05,420 --> 00:11:10,000 OK so this is going to be the name of the format that the user can select for. 159 00:11:10,010 --> 00:11:11,200 This takes one here. 160 00:11:11,210 --> 00:11:13,220 This is takes number one. 161 00:11:13,430 --> 00:11:16,340 And as you can see here I have this summary. 162 00:11:16,940 --> 00:11:21,680 So the Samadi is going to be a string value that I will be showing you in a minute. 163 00:11:21,740 --> 00:11:27,450 So it's going to give you a description about this specific tick box preference the summary. 164 00:11:27,800 --> 00:11:29,970 And we have this default value. 165 00:11:30,230 --> 00:11:34,070 So default the default value is going to be the default itself. 166 00:11:34,190 --> 00:11:36,140 Chunk 5 that or T.F.. 167 00:11:36,170 --> 00:11:42,650 So as you can see here in our project structure here in our assets folder I have this Faunce directory. 168 00:11:42,670 --> 00:11:46,780 And as you can see here I have this and chaunced 5 that Auty ATF. 169 00:11:46,910 --> 00:11:52,670 So it is very important that the name that you actually put here for this default value must be the 170 00:11:52,670 --> 00:11:53,690 same as this name. 171 00:11:53,690 --> 00:11:55,470 Here inside this Faunce directory. 172 00:11:55,520 --> 00:12:01,230 So here as you can see I am actually closing this tag here this checkbox preference. 173 00:12:01,640 --> 00:12:05,850 And again here I actually created another checkbox preference.
