WEBVTT 00:00.580 --> 00:04.720 So let's return to the main activity, Java, to complete the application. 00:08.240 --> 00:11.480 So now we should create a question object from the questions class. 00:13.880 --> 00:16.610 And we can find the answer. 00:17.770 --> 00:19.210 The score of the user. 00:21.490 --> 00:27.400 I will update the questions depending on the length of the questions, so I'll create the integer that 00:27.400 --> 00:29.230 will keep the length of the questions. 00:30.320 --> 00:35.400 Let's create a variable to randomly update the questions with the random class. 00:36.790 --> 00:38.710 And as you can see, it's imported here. 00:41.090 --> 00:45.380 Now, to update the questions I would call the method here and. 00:47.470 --> 00:49.630 I also need to create a method for this. 00:52.410 --> 00:53.730 So that's created here. 00:56.040 --> 01:01.890 You can set the text to be displayed in the text view, either when declaring it in your layout file 01:02.400 --> 01:05.430 or by using its set text method. 01:07.200 --> 01:10.740 So I said the text for all answers and questions. 01:23.810 --> 01:31.850 OK, so I guess here now I missed something, yes, here I should have created a new random instance. 01:32.980 --> 01:34.390 OK, great, so let's. 01:35.740 --> 01:37.900 Yeah, let's complete the listener method's. 01:39.270 --> 01:45.330 So we must write a conditional statement here to check the correctness of the answer, and if the answer 01:45.330 --> 01:47.490 is true, the score must be increased. 01:55.890 --> 02:01.820 If the answer is false, then we need a method to finish the game, so we'll create the last method 02:01.980 --> 02:03.950 game over for that purpose. 02:05.950 --> 02:10.480 So when the game is over, an alert will appear thanks to the alert dialogue builder. 02:11.630 --> 02:16.910 And we'll set a message for this alert that will also display this score. 02:27.680 --> 02:34.400 So let's say there's going to be two options on this alert dialogue, we'll create a positive button 02:34.400 --> 02:36.590 for the user who wants to continue the game. 02:38.930 --> 02:41.690 The dialogue interface on Click Listener. 02:42.620 --> 02:48.770 Is used to allow the creator of a dialogue to run some code when an item on the dialogue is clicked. 02:52.070 --> 02:59.510 And the star activity method starts in the instance of the display message activity that specified by 02:59.510 --> 03:00.290 the intent. 03:02.370 --> 03:05.040 So next, we'll need to create the intent. 03:07.070 --> 03:15.080 The intent represents an app's intent to do something right, so get application context will return 03:15.080 --> 03:17.750 the context for the entire application. 03:21.110 --> 03:24.320 And if the game is over and the user may want to exit. 03:25.400 --> 03:30.620 Well said a negative button for this, and it will finish the game and exit. 03:39.400 --> 03:46.480 And then finally, we need to create an alert dialog object and call it with a show method to display 03:46.480 --> 03:47.050 the screen. 03:50.340 --> 03:54.890 So now let's complete all the methods for each answer. 03:57.050 --> 04:03.500 Just copy this part and paste for every method of the answers, and don't forget to change the number, 04:03.500 --> 04:04.190 the answers. 04:08.940 --> 04:15.780 All right, so actually, it's a very simple project, but the project is complete now. 04:17.100 --> 04:22.410 But before running the app, you should select the emulator that you created before. 04:23.570 --> 04:25.010 All right, so let's start, Dhiab. 04:26.600 --> 04:32.750 And our Android studio is installing the app on the video and see how it starts the emulator. 04:34.600 --> 04:35.920 All right, so let's try out the game. 04:44.590 --> 04:47.500 Well, look at that, it's working as expected. 04:49.770 --> 04:55.020 But I'll tell you, let's delete the hard coded text view that's displayed first before getting the 04:55.020 --> 04:55.470 score. 04:57.910 --> 05:01.300 So to do that, I don't want to go to the design section. 05:02.630 --> 05:05.150 Delete the default text for the score. 05:06.650 --> 05:08.470 And let's run the app again. 05:11.300 --> 05:19.220 All right, great, now you can, of course, change the UI for a much better view or extend the capabilities 05:19.220 --> 05:23.480 of the app if you want to, but this is what we're going to use here to for.
