This article is about how android customizes the effects of various elements in set when animating. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

Fade in and out animation effect

Android:fromAlpha= "1.0f" / / initial transparency

Android:toAlpha= "0.0f" / / end transparency

Android:duration= "500" / / Animation duration (in ms)

Gradual size stretch animation effect

Android:fromXScale= "1.0" android:toXScale=" 1.4" / / horizontal stretch

Android:fromYScale= "1.0" android:toYScale= "0.6" / / Vertical Compression

Horizontal and / or vertical motion

There are three presentation formats:

1. The percentage of 100% to 100% relative to itself.

2. The percentage of 100% P to 100% P relative to the parent component

3.folat value has no suffix to indicate absolute value

Android:fromXDelta= "100% p" android:toXDelta= "0" / / from the right boundary of the parent component to the middle

Rotation animation

Android:fromDegrees= "0" / / start Angle

Android:toDegrees= "- 45" / / negative end angle indicates counterclockwise

Multiple animation combinations

/ / initialize Translate animation

TranslateAnimation = new TranslateAnimation (0.1f 100.0f, 0.1f 100.0f)

/ / initialize Alpha animation

AlphaAnimation = new AlphaAnimation (0.1f, 1.0F)

/ / Animation set

AnimationSet set = new AnimationSet (true)

Set.addAnimation (translateAnimation)

Set.addAnimation (alphaAnimation)

/ / set animation time (works on each animation)

Set.setDuration (1000)

This.startAnimation (set)
