Overview

Android Animations Actions

Actions for android animations. Inspired by libgdx scene2d actions.

The main goal of this project is making creating of complex animations easier. You may create animations like in demo with just a couple lines of code.

##Actions sequence - executes actions sequentially
delay - inserts pause into sequence
run - will run target runnable, useful in sequences
parallel - executes actions at the same time
color - color animation for view
scaleTo - scales view to defined values
scaleBy - scales view by defined values
alpha - alpha animation
fadeIn - fades alpha to 1
fadeOut - fades alpha to 0
rotateTo - rotates view to defined degree
rotateBy - rotates view by defined degree
moveTo - moves view to defined x, y
moveBy - moves view by defined x, y
repeat - repeats action using defined number of times
forever - repeats action infinite

play - plays specified action on specified view

##Interpolations Library contains class Interpolations with different predefined interpolations which may be useful for animations.

Demo

For better quality please check package demo in the project.

Gradle

repositories {
    jcenter()
}

dependencies {
    compile 'com.dtx12:actions:0.1.4'
}

Crash on adding parallel
play(forever(parallel( sequence( scaleBy(2f, 2f, 2, Interpolations.QuadraticEaseOut), scaleBy(-2f, -2f), delay(0.2f) ), fadeOut()) ), radar);

MainActivity 69 is the first line, with play() function

How i can free a view of the final estates of actions?

Hello I love your library I've just realized that I could not do certain things, how I can free a view of the final states of an animation? and How to change the colors, and how I can stop a forever?

Fix broken headings in Markdown files

GitHub changed the way Markdown headings are parsed, so this change fixes it.

See bryant1410/readmesfix for more information.

The view does not go to the "first place" if moveBy reverse value!
This is my code:

LinearInterpolator interpolator = new LinearInterpolator(); float width = (float) worldMap[0].getWidth(); //width = 400; float duration = 1f; play(forever(sequence(moveBy(-width, 0f, duration, interpolator), moveBy(width, 0f, duration, interpolator))), worldMap[0]);

I am trying to make a loop but The view does not go to the first place, and instead it moves left more than moving to right! So, after few seconds, the view goes out of the screen! What is wrong here?

Sequence method's parameter is too long

The method can be hard to read when the sequence is very long. Maybe the API can be changed to Builder pattern, something like

play().sequence().fadeOut().fadeIn(2).on(view)
