The ObjectAnimator relies on reflection and uses the button's getAlpha() and setAlpha() methods to perform the animation. Notice that the "alpha" is designated as a string type.

This code will execute the animation to fade out the button. ofFloat ( tvLabel, "alpha", 0.2f ) fadeAnim. We can use the ObjectAnimator method to execute simple animations for a particular property on a specified object: ObjectAnimator fadeAnim = ObjectAnimator. Nine Old Androids has now been deprecated and no longer being supported but can still be used by adding this line to your app/adle file: implementation 'com.nineoldandroids:library:2.4.0'Ī library that simplifies common animations is called AndroidViewAnimations and makes certain common animations on views much easier to achieve.

In the past, the way to use animations compatible with pre-3.0 Android versions is to use NineOldAndroids for all our property animations. TranslationX, translationY, translationZ (API 21+) The primary motivations for the introduction of the property animations system are outlined in this post from 2011 introducing property animations.Ĭommon properties commonly animated on views include: Property Property animations were a more recent Android feature introduced in 3.0.

Frequently used to animate views on screen such as rotating an image or fading out a button. Property Animations - This is the animation of any property between two values.Powered by these animation frameworks, there are five relevant types of animations: Using the design support library, view hierarchy animations can be supported down to Android 4.0 devices.

Transition Animations - For Android 4.4 devices and above, the Transitions API framework enables layout changes within an activity.View Animations - Slower and less flexible deprecated since property animations were introduced.Property Animations - The most powerful and flexible animation system introduced in Android 3.0.There are actually three distinct animation frameworks for Android: This is typically used for any dynamic movement for views including position changes, rotations, expansion or coloration changes.Īnimations like many resources for Android can be defined both through XML resources as well asĭynamically within the Java code. These can be applied to anything within the Android application. Property animations allow us to animate any property of any object from one value to another over a specified duration. There are three animation systems that work differently for different cases but the most important are Property animations. Android supports powerful animations for both views and transitions between activities.
