Animation and coroutines

AnimatorX

动画 + 协程 = Power！

准备

1. Add jitpack to build.gradle

allprojects {
    repositories {
        ...
        maven { url 'https://jitpack.io' }
    }
}

2. Add dependency

dependencies {
	implementation 'com.github.ssseasonnn:AnimatorX:1.0.0'
}

使用方法

执行单个动画

• 位移动画

launch {
    //沿着X轴正向移动300像素
    button.translationX(0f, 300f)
}

launch {
    //沿着Y轴正向移动300像素
    button.translationY(0f, 300f)
}

launch {
    //沿着Z轴正向移动300像素
    button.translationZ(0f, 300f)
}

• 缩放动画

launch {
    //沿着X轴缩放，从原始大小放大到3倍大小
    button.scaleX(1f, 3f)
}

launch {
    //沿着Y轴缩放，从原始大小放大到3倍大小
    button.scaleY(1f, 3f)
}

• 旋转动画

launch {
    //沿着button中心旋转180度
    button.rotation(0f, 180f)
}

launch {
    //沿着X轴旋转
    button.rotationX(0f, 180f)
}

launch {
    //沿着Y轴旋转
    button.rotationY(0f, 180f)
}

• 渐变动画

launch {
    //渐变透明
    button.alpha(1f, 0f)
}

组合多个动画

• 顺序执行，只需要把需要执行的动画按照从上到下的顺序排列即可

launch {
    button1.translationX(0f, 300f)
    button2.alpha(1.0f, 0.1f)
    button3.rotation(0f, 180f)
    button4.scaleX(1.0f, 3f)

    //依次执行button1的位移动画，button2的渐变动画，button3的旋转动画，button4的缩放动画
}

• 并列执行，只需要把需要同时运行的动画放进async块中即可

launch {
    val anim1 = async { button1.translationX(0f, 300f)  }
    val anim2 = async { button2.alpha(1.0f, 0.1f) }
    val anim3 = async { button3.rotation(0f, 180f) }
    val anim4 = async { button4.scaleX(1.0f, 3f) }
    awaitAll(anim1, anim2, anim3, anim4)

    //这次四个动画将会一起执行
}

最后

除此之外，你还能享受到所有协程的其他特性，例如使用 delay() 对动画进行延时， 使用 repeat() 对动画进行重复播放等等，发挥你的想象力把！
