The Android framework has a large set of
View classes for
interacting with the user and displaying various
types of data. But
sometimes your app has unique needs that aren’t covered by the built-in views. This class shows you
how to create your
own views that are robust and reusable.
- Creating a View Class
- Create a class that acts like a built-in view, with custom
attributes and support from the Android Studio layout editor.
- Custom Drawing
- Make your view visually distinctive using the Android graphics system.
- Making the View Interactive
- Users expect a view to react smoothly and naturally to input gestures.
This lesson discusses how to use gesture detection, physics, and animation
to give your user interface a professional feel.
- Optimizing the View
- No matter how beautiful your UI is, users won't love it if it
doesn't run at a consistently high frame rate. Learn how to avoid common
performance problems, and how to use hardware acceleration to make your
custom drawings run faster.
