Android Studio 4.1 Development Essentials – Kotlin Edition

By: Neil Smyth

Overview of this book

Android 11 has a ton of new capabilities. It comes up with three foci: a people-centric approach to communication, controls to let users quickly access and manage all of their smart devices, and privacy to give users more ways to control how data on devices is shared. This book starts off with the steps necessary to set up an Android development and testing environment, followed by an introduction to programming in Kotlin. An overview of Android Studio and its architecture is provided, followed by an in-depth look at the design of Android applications and user interfaces using the Android Studio environment. You will also learn about the Android architecture components along with some advanced topics such as touch screen handling, gesture recognition, the recording and playback of audio, app links, dynamic delivery, the AndroidStudio profiler, Gradle build configuration, and submitting apps to the Google Play Developer Console. The concepts of material design are also covered in detail. This edition of the book also covers printing, transitions, and cloud-based file storage; foldable device support is the cherry on the cake. By the end of this course, you will be able to develop Android 11 Apps using Android Studio 4.1, Kotlin, and Android Jetpack.

26.15 Adding a Group

To add a Group to a layout, right-click on the layout and select the Add Group option from the Helpers menu, or use the toolbar menu options as shown previously in Figure 26-29. Alternatively, locate the Group item in the Helpers section of the Palette and drag and drop it either onto the layout canvas or Component Tree panel.

To add widgets to the group, select them in the Component Tree and drag and drop them onto the Group entry. Figure 26-37 for example, shows three selected widgets being added to a group:

Figure 26-37

Any widgets referenced by the group will appear italicized beneath the group entry in the Component Tree as shown in Figure 26-38. To remove a widget from the group, simply select it and tap the keyboard delete key:

Once widgets have been assigned to the group, use the Constraints section of the Attributes tool window to modify the visibility setting:
