  • 00:00:00 In this video, Brad explains the basics of Kotlin and then demonstrates how to build a simple to-do list app using the language. He notes that the crash course is really for people who have never worked with Android before and only know Kotlin basics. If you're interested in learning more advanced topics in Android development, then make sure to check out his channel for more tutorials.
  • 00:05:00 In this video, the instructor shows how to set up Android Studio for Kotlin development. First, they show how to install the Java Development Kit (JDK) and the Android Studio. Next, they show how to install the Android Emulator. Next, they show how to create a new project in Android Studio. Finally, they show how to create and run the project.
  • 00:10:00 In this video, the author demonstrates how to build a simple Android app with Kotlin. The main file in the app is a class that inherits from the AppCompatActivity class, which provides the behavior of a real activity. The oncreate function sets the content view to a layout file, and if we launch the app, we will see a white screen with a hello world text view.
  • 00:15:00 In this video, the author discusses how to create a simple android app with Kotlin by including dependencies, setting up a layout, and styling the app.
  • 00:20:00 The video shows how to create an Android app with Kotlin, using a constraint layout to center and resize the recycler view.
  • 00:25:00 In this video, the presenter explains how to set constraints on a button in order to make it fit within the available space. They also show how to do the same with an edit text field.
  • 00:30:00 In this video, the presenter explains how to build an Android app with Kotlin. The presenter defines a layout for each item in a recycler view, and applies a gap between the check box and text view.
  • 00:35:00 In this video, the author explains how to create an Android app with Kotlin. First, they create a new class called "to do adapter" which will contain the main logic of the app. Next, they create a new class called "to do viewholder" which will hold the layout of a specific item. Finally, they define the constructor of the to do viewholder as a reference to the to do item view. This completes the app's recyclerview adapter.
  • 00:40:00 This YouTube video explains how to build a simple Android app using Kotlin. The first function to be explained is the oncreateviewholder function, which is responsible for creating the view holder for the recyclerview. Next, the getitemcount function is explained, which returns the number of items in the to-do list. Finally, the onbindviewholder function is explained, which binds the view holder to the to-do list.
  • 00:45:00 The video discusses how to build an Android app with Kotlin, using Kotlin's data binding features to bind the title and checked status of a checkbox to the text of a text view.
  • 00:50:00 This video explains how to use Kotlin to create an Android app with a text view that uses dot pain flags to specify which flags to apply, and an onbindviewholder function to call the toggle strikethrough function when the checkbox is checked.
  • 00:55:00 In this video, the presenter discusses how to build an Android app with Kotlin. First, they define two functions: one to delete all items from a list and another to add an item to the list. Next, they create an adapter for the recycler view and assign it to the main activity. Finally, they define a layout manager and assign it to the adapter.

This video covers the basics of creating an Android app in Kotlin, including how to use a layout manager and on-click listeners. While the app demonstrated in the video is functional, the author recommends that viewers check out his other videos for more advanced topics.

  • 01:00:00 This video discusses how to build an Android app with Kotlin, using a layout manager and on-click listeners. The layout manager will arrange items in a grid, and the on-click listeners will add, delete, and check to do items.
  • 01:05:00 This video explains how to build an Android app with Kotlin. The main() function first retrieves the size of the list of to-dos, and then creates and sets up a recyclerview with an onbindviewholder() function to bind the data of the to-dos list to a textview in a box. The toggle Strikethrough() function is also created to add a strikethrough flag to to any to-dos that are not checked. Then, two helper functions are created to add a new to-do item to the list and to delete the done to-dos. The app is then launched on a virtual device, and the oncreate() function is called when it is launched. The to-do adapter is assigned to a recycler view, and the layout manager is assigned to the recycler view. The app is then launched, and the oncreate() function is called again. The to-do adapter is used to display the to-dos list, and the user can enter to-dos into the textview, add done to-dos, and click on the add to do button to add new to-dos to the list.
  • 01:10:00 In this video, the author demonstrates how to create an app in Kotlin. While the app is functional, there are still some issues. The author recommends that viewers check out his other videos in which he covers more advanced Android development topics.
