Wow, Android View Animation! (capital letter of each word forms
WAVA)
I wanna build another fancy Android animation library, but I was still thinking how to do that.
daimajia has built an amazing library named AndroidViewAnimations, it's really really awesome.
Currently wava is just a library based on AndroidViewAnimations with many updates. Since it has changed a lot from the latest release of AndroidViewAnimations (although I tried to keep the API as same as before), I think better make another one than pulling requests.
Later I will try my best to add other fancy new features to wava, star it if you have any interest.
Sample
Usage
It's almost the same.
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.add this in your build.gradle file in root project
allprojects {
repositories {
...
maven {
url "https://www.jitpack.io"
}
}
}
2.add the following dependency
dependencies {
compile 'com.github.hujiaweibujidao:wava:1.0.0'
}
Changes
The following are main changes from AndroidViewAnimations:
1.removed deprecated NineOldAndroids.
New applications should use minSdkVersion="14" or higher which has access to the platform animation APIs.
For example, animation reset no longer needs ViewHelper
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.simplified the core YoYo class (including Builder and YoYoString) while keeping the original API.
public static class Builder {
private static final int DEFAULT_REPEAT = 1;//?????????
private static final long DEFAULT_DELAY = 0;//??????????
private static final boolean DEFAULT_RESET = false;//???????????
private static final long DEFAULT_DURATION = 1000;//?????????1?
private View target;//???view
private long delay = DEFAULT_DELAY;//??????
private long duration = DEFAULT_DURATION;//??????
private int repeat = DEFAULT_REPEAT;//??????
private boolean reset = DEFAULT_RESET;//?????????????????true????
private BaseViewAnimator animator;//animator?
private Interpolator interpolator;//interpolator ?????
private List<Animator.AnimatorListener> listeners = new ArrayList<Animator.AnimatorListener>();
//??????
//??????????animator????????
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;
}
//??play???????????????????????YoYoString
public YoYoString playOn(View target) {
this.target = target;
start();
return new YoYoString(this.animator);
}
//builder???start????animatorset??
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.added supports to animation replay and animation reset after animation ends.
public void start() {
reset();
prepare();
if (mRepeat != 0) {
for (Animator animator : mAnimatorSet.getChildAnimations()) {
((ValueAnimator) animator).setRepeatCount(mRepeat > 0 ? mRepeat - 1 : mRepeat);
//?????
//((ValueAnimator) animator).setRepeatMode(ValueAnimator.REVERSE);
}
}
if (mRest) {
mAnimatorSet.addListener(new AnimatorListenerAdapter() {
@Override
public void onAnimationEnd(Animator animation) {
reset();
}
}
);
}
mAnimatorSet.start();
}
4.replaced the original dependency AndroidEasingFunctions with my another library yava.
public class LandingAnimator extends BaseViewAnimator {
@Override
protected void prepare() {
//before //
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)) //
);
//after
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.simplified all the ViewAnimator with easy access way to mAnimatorSet and mTarget.
public class BounceAnimator extends BaseViewAnimator {
@Override
public void prepare() {
mAnimatorSet.playTogether(
ObjectAnimator.ofFloat(mTarget, "translationY", 0, 0, -30, 0, -15, 0, 0)
);
}
}
6.modified the effect visualization code while keeping it same as before.
