You then need to set this AnimationDrawable as a background resource for our ImageView control in the activity layout. The animation-list tag gets converted into an AnimationDrawable object representing the collection of images. This XML file needs to be placed in the /res/drawable/frame_animation.xml subdirectory as well.Įach frame points to one of the images you have assembled through their resource IDs. You will then construct an XML file that defines the AnimationDrawable using a list of these images. To use this AnimationDrawable class, start with a set of Drawable resources (for example, a set of images) placed in the /res/drawable subdirectory. AnimationDrawable, in addition to being a Drawable, can take a list of other Drawable resources (like images) and render them at specified intervals. These objects are commonly used as backgrounds for views. In Android, frame-by-frame animation is implemented through the class AnimationDrawable. Tutorial 1, Tutorial 2.įrame-by-frame animation is where a series of images are shown in succession at quick intervals so that the final effect is that of an object moving or changing. Property animation is more flexible than view animation, and it offers more features. It changes an object's properties over a specified period of time.The property animation system was introduced in Android 3.0 (API level 11). It's relatively easy to set up and offers enough capabilities for many use cases. The Android view animation system is older than the property animation system and can only be used for Views. It calculates animation using start points, end points, rotation, and other aspects of animation.
