### wava
> Wow, Android View Animation!
我想写一个很好用的Android动画制作库，具体如何做目前还在思考中 🐈
目前做的最好的Android动画库项目是[@代码家](https://github.com/daimajia)的[AndroidViewAnimations](https://github.com/daimajia/AndroidViewAnimations)，这个项目真的非常棒。
项目`wava`目前只是参考这个项目并对其代码进行修改和改进，后期我将添加更多有意思的功能。
具体什么功能请大家期待下吧，感兴趣的话可以关注这个项目哈 😜
[When Math Meets Animation(1)](https://javayhu.github.io/blog/2016-05-26-when-math-meets-android-animation-1)
[When Math Meets Animation(2)](https://javayhu.github.io/blog/2016-05-27-When-Math-meets-Android-Animation-2)
[When Math Meets Animation(3)](https://javayhu.github.io/blog/2016-05-28-When-Math-meets-Android-Animation-3)
### Sample
### Usage
和原项目的使用方式基本相同
```java
YoYo.with(technique).duration(1200)
.interpolate(new AccelerateDecelerateInterpolator())
.listen(new AnimatorListenerAdapter() {
@Override
public void onAnimationCancel(Animator animation) {
Toast.makeText(MainActivity.this, "canceled", Toast.LENGTH_SHORT).show();
}
})
.playOn(mTarget);
```
### Setup
1.在项目根目录的build.gradle文件中加入
```
allprojects {
repositories {
...
maven { url "https://www.jitpack.io" }
}
}
```
2.然后在需要的build.gradle文件中加入依赖
```
dependencies {
compile 'com.github.hujiaweibujidao:wava:1.0.0'
}
```
### Changes
目前主要修改和改进的地方：
1.去掉了过时的[NineOldAndroids](https://github.com/JakeWharton/NineOldAndroids)库（如果Android项目的`minSdkVersion="14"`可以直接使用系统提供的动画API）；
例如，动画恢复部分的代码就不再需要使用`ViewHelper`了
```java
public void reset() {
mTarget.setAlpha(1);
mTarget.setScaleX(1);
mTarget.setScaleY(1);
mTarget.setTranslationX(0);
mTarget.setTranslationY(0);
mTarget.setRotation(0);
mTarget.setRotationX(0);
mTarget.setRotationY(0);
mTarget.setPivotX(mTarget.getMeasuredWidth() / 2.0f);
mTarget.setPivotY(mTarget.getMeasuredHeight() / 2.0f);
}
```
2.大幅度精简了核心类`YoYo`（包括其中的`Builder`和`YoYoString`类）内部的代码，但是只做扩展，基本保持了原有接口不变；
```java
public static class Builder {
private static final int DEFAULT_REPEAT = 1;//动画默认只播放一次
private static final long DEFAULT_DELAY = 0;//动画默认没有启动延时
private static final boolean DEFAULT_RESET = false;//动画结束默认不恢复原状
private static final long DEFAULT_DURATION = 1000;//动画时间间隔默认是1秒
private View target;//作用的view
private long delay = DEFAULT_DELAY;//动画启动延迟
private long duration = DEFAULT_DURATION;//动画持续时长
private int repeat = DEFAULT_REPEAT;//动画重复次数
private boolean reset = DEFAULT_RESET;//动画结束之后是否恢复到原来的状态，true表示恢复
private BaseViewAnimator animator;//animator类
private Interpolator interpolator;//interpolator 时间插值类
private List listeners = new ArrayList();//动画的监听器
//两个构造函数都将使得animator成为一个非空对象
private Builder(Techniques technique) {
this.animator = technique.getAnimator();
}
private Builder(BaseViewAnimator animator) {
this.animator = animator;
}
public Builder duration(long duration) {
this.duration = duration;
return this;
}
public Builder delay(long delay) {
this.delay = delay;
return this;
}
public Builder interpolate(Interpolator interpolator) {
this.interpolator = interpolator;
return this;
}
public Builder listen(AnimatorListenerAdapter listener) {
this.listeners.add(listener);
return this;
}
public Builder reset(boolean reset) {
this.reset = reset;
return this;
}
public Builder repeat(int count) {
this.repeat = count;
return this;
}
//调用play表示动画正式开始，返回结果是可以控制动画的对象YoYoString
public YoYoString playOn(View target) {
this.target = target;
start();
return new YoYoString(this.animator);
}
//builder内部的start方法，将animatorset启动
private void start() {
animator.setTarget(target).setDuration(duration).setInterpolator(interpolator)
.setStartDelay(delay).setRest(reset).setRepeat(repeat);
if (listeners.size() > 0) {
animator.addAllListeners(listeners);
}
animator.start();
}
}
```
3.在`BaseViewAnimator`中对增加了动画重复播放、动画结束时恢复等功能的支持，使用方式依然和以前一样简单；
```java
public void start() {
reset();
prepare();
if (mRepeat != 0) {
for (Animator animator : mAnimatorSet.getChildAnimations()) {
((ValueAnimator) animator).setRepeatCount(mRepeat > 0 ? mRepeat - 1 : mRepeat);//区别无穷次
//((ValueAnimator) animator).setRepeatMode(ValueAnimator.REVERSE);
}
}
if (mRest) {
mAnimatorSet.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
reset();
}
});
}
mAnimatorSet.start();
}
```
4.将原来依赖的[`AndroidEasingFunctions`](https://github.com/daimajia/AnimationEasingFunctions)替换成更加简单易用的[`yava`](https://github.com/hujiaweibujidao/yava)；
```java
public class LandingAnimator extends BaseViewAnimator {
@Override
protected void prepare() {
// mAnimatorSet.playTogether(
// Glider.glide(Skill.QuintEaseOut, mAnimatorSet.getDuration(), ObjectAnimator.ofFloat(mTarget, "scaleX", 1.5f, 1f)),
// Glider.glide(Skill.QuintEaseOut, mAnimatorSet.getDuration(), ObjectAnimator.ofFloat(mTarget, "scaleY", 1.5f, 1f)),
// Glider.glide(Skill.QuintEaseOut, mAnimatorSet.getDuration(), ObjectAnimator.ofFloat(mTarget, "alpha", 0, 1f))
// );
ObjectAnimator animator1 = ObjectAnimator.ofFloat(mTarget, "scaleX", 1.5f, 1f);
animator1.setInterpolator(EasingFunction.QUINT_OUT);
ObjectAnimator animator2 = ObjectAnimator.ofFloat(mTarget, "scaleY", 1.5f, 1f);
animator2.setInterpolator(EasingFunction.QUINT_OUT);
ObjectAnimator animator3 = ObjectAnimator.ofFloat(mTarget, "alpha", 0, 1f);
animator3.setInterpolator(EasingFunction.QUINT_OUT);
mAnimatorSet.playTogether(animator1, animator2, animator3);
}
}
```
5.简化了`ViewAnimator`内部的调用`AnimatorSet`和`TargetView`的方式；
```java
public class BounceAnimator extends BaseViewAnimator {
@Override
public void prepare() {
mAnimatorSet.playTogether(
ObjectAnimator.ofFloat(mTarget, "translationY", 0, 0, -30, 0, -15, 0, 0)
);
}
}
```
6.复制了原有的动画演示代码，略有修改，但是保证了效果如初。
