Android動(dòng)畫工具類的封裝實(shí)戰(zhàn)記錄

更新時(shí)間：2019年04月16日 11:50:04 作者：賈亦真亦賈

這篇文章主要給大家介紹了關(guān)于一次Android動(dòng)畫工具類的封裝實(shí)戰(zhàn)，文中通過示例代碼介紹的非常詳細(xì)，對(duì)各位Android開發(fā)者們具有一定的參考學(xué)習(xí)價(jià)值，需要的朋友們下面來一起學(xué)習(xí)學(xué)習(xí)吧

起因

最近在做一個(gè)組件化框架的封裝，現(xiàn)在開發(fā)到一些常用工具類的封裝了，突然意識(shí)到好像還沒有做動(dòng)畫的工具類，于是開始著手開發(fā)之。

思路

既然要做動(dòng)畫，肯定是要做屬性動(dòng)畫的工具類的封裝了，由于補(bǔ)間動(dòng)畫和逐幀動(dòng)畫并不能改變目標(biāo)動(dòng)畫主題的實(shí)際屬性，在Android的開發(fā)中已經(jīng)越來越少人去用這兩個(gè)動(dòng)畫框架做開發(fā)了，而屬性動(dòng)畫則相對(duì)的越來越廣泛的使用在開發(fā)過程中了，于是這次的工具類的封裝，只針對(duì)屬性動(dòng)畫來封裝。

屬性動(dòng)畫對(duì)應(yīng)的類叫做ObjectAnimator,主要就是用這個(gè)類來實(shí)現(xiàn)動(dòng)畫的一些基礎(chǔ)設(shè)置，其具體的使用方式我就不寫了，有興趣的朋友可以自行學(xué)習(xí)屬性動(dòng)畫的相關(guān)知識(shí)。

封裝屬性動(dòng)畫工具類不可避免的還要考慮到屬性動(dòng)畫的組合播放動(dòng)畫的需求，而屬性動(dòng)畫的組合播放有大約三種方式：

1.使用AnimatorSet的Builder來組合播放

AnimatorSet.Builder是一個(gè)使用的動(dòng)畫工具類，用于方便向AnimatorSet添加動(dòng)畫以及設(shè)置各種動(dòng)畫之間的關(guān)系。在 AnimatorSet.Builder中，共聲明了after(long)、after(Animator)、before(Animator)、with(Animator)等四個(gè)方法。

after(delay) 設(shè)置動(dòng)畫延遲delay時(shí)間后播放
after(anim) 設(shè)置在anim動(dòng)畫結(jié)束后播放此動(dòng)畫
before(anim) 設(shè)置此動(dòng)畫早于anim播放
with(anim) 設(shè)置此動(dòng)畫與anim一起播放

然后再調(diào)用paly(anim)方法來鏈?zhǔn)秸{(diào)用動(dòng)畫

AnimatorSet set=new AnimatorSet();
set.play(anim1).before(anim2).with(anim3).after(anim4);

我們注意到他是先執(zhí)行的after，然后是play和with同時(shí)執(zhí)行，最后執(zhí)行的before。所以大家記住這個(gè)順序，無論怎么寫，都是這個(gè)執(zhí)行順序。

2.使用AnimatorSet的playSequentially

API

playSequentially(List items)：添加一組動(dòng)畫，播放順序?yàn)橹鹨徊シ?/li>
playSequentially(Animator… items)：添加一組動(dòng)畫，播放順序?yàn)橹鹨徊シ?/li>

AnimatorSet bouncer = new AnimatorSet();
ObjectAnimator objectAnimatorA = ObjectAnimator.ofFloat(btnProperty, PropertyConstant.PROPERTY_TRANSLATION_X, 0f, 300f);
ObjectAnimator objectAnimatorB = ObjectAnimator.ofFloat(btnProperty, PropertyConstant.PROPERTY_TRANSLATION_Y, 0f, 300f);
ObjectAnimator objectAnimatorC = ObjectAnimator.ofFloat(btnProperty, PropertyConstant.PROPERTY_ROTATION, 0f, 360f);

bouncer.playSequentially(objectAnimatorA, objectAnimatorB, objectAnimatorC);

bouncer.setDuration(6000);
bouncer.start();

3.使用AnimatorSet的palyTogether

API

playTogether(Collection items)：添加一組動(dòng)畫，播放順序?yàn)橐黄鸩シ?/li>
playTogether(Animator… items)：添加一組動(dòng)畫，播放順序?yàn)橐黄鸩シ?/li>

AnimatorSet bouncer = new AnimatorSet();
ObjectAnimator objectAnimatorA = ObjectAnimator.ofFloat(btnProperty, PropertyConstant.PROPERTY_TRANSLATION_X, 0f, 300f);
ObjectAnimator objectAnimatorB = ObjectAnimator.ofFloat(btnProperty, PropertyConstant.PROPERTY_TRANSLATION_Y, 0f, 300f);
ObjectAnimator objectAnimatorC = ObjectAnimator.ofFloat(btnProperty, PropertyConstant.PROPERTY_ROTATION, 0f, 360f);

bouncer.playSequentially(objectAnimatorA, objectAnimatorB, objectAnimatorC);

bouncer.setDuration(6000);
bouncer.start();

掌握以上的知識(shí)點(diǎn)后，我的思路是，其實(shí)最后就是對(duì)執(zhí)行方式的封裝，所謂的執(zhí)行方式就是如何正常的調(diào)用play,playSequentially和playTogether三個(gè)方法，這里需要合理的封裝。

還有就是對(duì)于監(jiān)聽接口的封裝，每個(gè)ObjectAnimator都有三個(gè)接口：

Animator.AnimatorListener 對(duì)整個(gè)動(dòng)畫生命周期的監(jiān)聽

anim.addListener(new Animator.AnimatorListener() {
 @Override
 public void onAnimationStart(Animator animator) {
 Toast.makeText(MainActivity.this, "start", Toast.LENGTH_LONG).show();
 }

 @Override
 public void onAnimationEnd(Animator animator) {
 Toast.makeText(MainActivity.this, "End", Toast.LENGTH_LONG).show();
 }

 @Override
 public void onAnimationCancel(Animator animator) {
 Toast.makeText(MainActivity.this, "Cancel", Toast.LENGTH_LONG).show();
 }

 @Override
 public void onAnimationRepeat(Animator animator) {
 Toast.makeText(MainActivity.this, "rapeat", Toast.LENGTH_LONG).show();
 }
 });
 anim.start();

ValueAnimator.AnimatorUpdateListener 對(duì)于該動(dòng)畫逐幀的監(jiān)聽

ValueAnimator vanim = ValueAnimator.ofInt(0,10,20);
 vanim.addUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
 @Override
 public void onAnimationUpdate(ValueAnimator valueAnimator) {

 //如果之前的ValueAnimtor指定的是Int的i話，那么返回的Value就是int類型，
 也就是返回值類型與你創(chuàng)建的類型一致
 int value = (int) valueAnimator.getAnimatedValue();
 }
 });

Animator.AnimatorPauseListener 對(duì)于該動(dòng)畫的暫停和播放的監(jiān)聽

new Animator.AnimatorPauseListener() {
 @Override
 public void onAnimationPause(Animator animator) {
 
 }

 @Override
 public void onAnimationResume(Animator animator) {

 }
 }

由于我的初步構(gòu)想是使用建造者模式的鏈?zhǔn)秸{(diào)用模式來設(shè)計(jì)我的工具類，如果按照普通的寫法，那么整個(gè)監(jiān)聽接口的設(shè)置將會(huì)是災(zāi)難性的，因?yàn)樗械谋O(jiān)聽接口的設(shè)置都是混亂的，所以這里必須處理，我的思路是，學(xué)習(xí)SpringSecurity的鏈?zhǔn)秸{(diào)用設(shè)計(jì)，為每個(gè)類型的監(jiān)聽設(shè)置自己的類，然后再讓工具主類調(diào)用該類型的監(jiān)聽接口，然后設(shè)置完畢后，在通過該監(jiān)聽接口類的and（）方法回到工具類的主類型來，這樣在鏈?zhǔn)秸{(diào)用的時(shí)候就有一個(gè)起止順序，不會(huì)混亂執(zhí)行了，而且如果不用設(shè)置監(jiān)聽，不調(diào)用監(jiān)聽類設(shè)置也不會(huì)影響主類的執(zhí)行。

截取關(guān)鍵代碼,以Play方法的監(jiān)聽接口設(shè)置為例：

/**
*工具類的主類
**/
public static class AnimatorSetWrap{
 PlayAnimationListener playListener;
 public PlayAnimationListener toAddPlayListener(){
 playListener=new PlayAnimationListener(this);
 return playListener;
 }
 }

/**
 * Play方法對(duì)應(yīng)的ObjectAnimator的監(jiān)聽實(shí)例
 */
 public static class PlayAnimationListener implements IAnimatorListener<PlayAnimationListener>{

 private Animator.AnimatorListener animatorListener;
 private ValueAnimator.AnimatorUpdateListener updateListener;
 private Animator.AnimatorPauseListener pauseListener;

 public AnimatorSetWrap animatorSetWrap;
 public PlayAnimationListener(AnimatorSetWrap animatorSetWrap){
 this.animatorSetWrap=animatorSetWrap;
 }
 @Override
 public PlayAnimationListener setAnimatorListener(Animator.AnimatorListener animatorListener) {
 this.animatorListener=animatorListener;
 return this;
 }

 @Override
 public PlayAnimationListener setUpdateListener(ValueAnimator.AnimatorUpdateListener animatorListener) {
 this.updateListener=animatorListener;
 return this;
 }

 @Override
 public PlayAnimationListener setPauseListener(Animator.AnimatorPauseListener animatorListener) {
 this.pauseListener=animatorListener;
 return this;
 }
 @Override
 public AnimatorSetWrap and(){
 return animatorSetWrap;
 }
 }

/**
 * 動(dòng)畫監(jiān)聽的公用模板接口
 * @param <T>
 */
 interface IAnimatorListener<T>{
 /**
 * 設(shè)置AnimatorListener的方法
 * @param listener
 * @return
 */
 T setAnimatorListener(Animator.AnimatorListener listener);

 /**
 * 設(shè)置AnimatorUpdateListener的方法
 * @param listener
 * @return
 */
 T setUpdateListener(ValueAnimator.AnimatorUpdateListener listener);

 /**
 * 設(shè)置AnimatorPauseListener的方法
 * @param listener
 * @return
 */
 T setPauseListener(Animator.AnimatorPauseListener listener);

 /**
 * 橋接動(dòng)畫監(jiān)聽與動(dòng)畫工具類的方法
 * @return
 */
 AnimatorSetWrap and();
 }

具體的使用方法：

AnimatorUtil.AnimatorSetWrap animatorSetWrapDemo=new AnimatorSetWrap().toAddPlayListener().setUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
 @Override
 public void onAnimationUpdate(ValueAnimator valueAnimator) {
 LogUtils.e("數(shù)值:"+valueAnimator.getAnimatedValue());
 }
 }).and();

通過這種鏈?zhǔn)秸{(diào)用，只要調(diào)用到and()方法就又回到了AnimatorSetWrap工具類的實(shí)例，剩下就可以繼續(xù)調(diào)用其他動(dòng)畫的方法并播放動(dòng)畫了。

  @Override
  public void onAnimationUpdate(ValueAnimator valueAnimator) {

  }
 }).and().then(viewAnimator, AnimatorUtils.TRANSY, null, -1, -2, 0, 100, 200, 300, 200, 100, 0).toAddThenListener().setUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
  @Override
  public void onAnimationUpdate(ValueAnimator valueAnimator) {
  LogUtils.e("then2:"+valueAnimator.getAnimatedValue());
  }
 }).and().then(viewAnimator, AnimatorUtils.SCALEX, new LinearInterpolator(), 0, 1000, 0, 10).toAddWithListener().setUpdateListener(new ValueAnimator.AnimatorUpdateListener() {
  @Override

上面的動(dòng)畫調(diào)用方法是我亂寫的，具體就是為了演示工具類的使用方法，你可以改成自己的調(diào)用方法。
