Android Animation APIs

Introduction

Android provides a range of animation APIs to help you add motion to your UI. Whether you want to animate window pop-ups, transitions, or custom interactions, there's an API for you.

Animation Types

Android supports three main types of animation:

Window Animation Scale

Controls the speed of window animation playback, such as menu pop-ups.

Transition Animation Scale

Controls the speed of transition animations between activities and fragments.

Animator Duration Scale

Controls the speed of all other custom animations created using the Animator class.

Starting Activities with Transitions

You can use the startActivity() method to start an activity with a transition animation. This animation can be based on a shared element between the two activities, allowing for a smooth and seamless transition. You can also start an activity with multiple shared elements, creating a more complex and engaging transition.

Activity Transitions in Material Design Apps

Material Design apps follow a specific set of animation guidelines to ensure a consistent and intuitive user experience. These guidelines include using smooth and fluid animations for transitions, as well as using animation to highlight important UI elements.

Additional Animation APIs

In addition to the above, Android provides a number of other animation APIs, such as: * PropertyAnimator: Animates a specific property of a view. * ValueAnimator: Animates a value over time. * ObjectAnimator: Animates an object property over time. * AnimatorSet: Combines multiple animations into a single, synchronized animation.
