This is the first episode of a new Kotlin camera2 API series. Which follows on from the Kotlin camera2 preview series.
The Kotlin Camera2 API Video Icons Android development tutorial describes how to add image icons to an Android Fragment.
After adding the image icons to the Android ConstraintLayout file, on click listeners will be implemented for each image icon in the Kotlin fragment preview file.
An Android Chronometer view will also be added to the Android ConstraintLayout. The Android Chronometer will be used to display the video record capture time.
In this Kotlin on Android tutorial we will cover:
- How to add icons using Android Studio
- Adding an Android ConstraintLayout to a Fragment layout
- Inserting icons into an Android ConstraintLayout

Conclusion
In this Kotlin on Android tutorial series, we described how to add image icons to an Android ConstraintLayout using the Android Studio GUI tool.
Once the ImageView’s had been inserted and their constraints added, on click listeners were implemented in the Android fragment file.
An Android Chronometer view was also added to display the record capture time to the user.
The next Kotlin on Android camera2 episode will describe how to set up the MediaRecorder.
