这篇文章将为大家详细讲解有关Android如何实现直播app送礼物连击动画效果，小编觉得挺实用的，因此分享给大家做个参考，希望大家阅读完这篇文章后可以有所收获。

最近在做公司的直播项目，需要实现一个观看端连击送礼物的控件：

直接上代码:

public class CustomGiftView extends LinearLayout {  private Timer timer;  private List<View> giftViewCollection = new ArrayList<>();  public CustomGiftView(Context context) {    this(context,null);  }  public CustomGiftView(Context context, @Nullable AttributeSet attrs) {    this(context, attrs,0);  }  public CustomGiftView(Context context, @Nullable AttributeSet attrs, int defStyleAttr) {    this(context, attrs, defStyleAttr,0);  }  public CustomGiftView(Context context, AttributeSet attrs, int defStyleAttr, int defStyleRes) {    super(context, attrs, defStyleAttr, defStyleRes);  }    public void pause() {    if (null != timer) {      timer.cancel();    }  }  public void cancel() {    if (null != timer) {      timer.cancel();    }  }  public void resume() {    clearTiming();  }    private void clearTiming() {    TimerTask task = new TimerTask() {      @Override      public void run() {        int count = CustomGiftView.this.getChildCount();        for (int i = 0; i < count; i++) {          View view = CustomGiftView.this.getChildAt(i);          CustomRoundView crvheadimage = (CustomRoundView) view.findViewById(R.id.crvheadimage);          long nowtime = System.currentTimeMillis();          long upTime = (Long) crvheadimage.getTag();          if ((nowtime - upTime) >= 3000) {            final int j = i;            post(new Runnable() {              @Override              public void run() {                CustomGiftView.this.removeViewAt(j);              }            });//            removeGiftView(i);            return;          }        }      }    };    if (null != timer) {      timer.cancel();    }    timer = new Timer();    timer.schedule(task, 0, 100);  }    private View addGiftView() {    View view = null;    if (giftViewCollection.size() <= 0) {            view = LayoutInflater.from(getContext()).inflate(R.layout.item_gift, null);      LinearLayout.LayoutParams lp = new LinearLayout.LayoutParams(ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT);      lp.topMargin = 10;      view.setLayoutParams(lp);      this.addOnAttachStateChangeListener(new View.OnAttachStateChangeListener() {        @Override        public void onViewAttachedToWindow(View view) { }        //复用Item，当一个View移除时将它放到池内        @Override        public void onViewDetachedFromWindow(View view) {          if (giftViewCollection.size() < 5) {            giftViewCollection.add(view);          }        }      });    } else {      //如果Item池内有缓存的view，将它取出来，并从池中删除      view = giftViewCollection.get(0);      giftViewCollection.remove(view);    }    return view;  }    public void showGift(String tag) {    View giftView = this.findViewWithTag(tag);    if (giftView == null) {      giftView = addGiftView();      giftView.setTag(tag);      CustomRoundView crvheadimage = (CustomRoundView) giftView.findViewById(R.id.crvheadimage);      final MagicTextView giftNum = (MagicTextView) giftView.findViewById(R.id.giftNum);      TextView sender = (TextView) giftView.findViewById(R.id.sender);      sender.setText(tag);      giftNum.setText("x1");      crvheadimage.setTag(System.currentTimeMillis());      giftNum.setTag(1);      this.addView(giftView,0);//      llgiftcontent.invalidate();      TranslateAnimation inAnim = (TranslateAnimation) AnimationUtils.loadAnimation(getContext(), R.anim.gift_in);      giftView.startAnimation(inAnim);      inAnim.setAnimationListener(new Animation.AnimationListener() {        @Override        public void onAnimationStart(Animation animation) { }        @Override        public void onAnimationEnd(Animation animation) {          //注释调，第一次添加没动画//          giftNumAnim.start(giftNum);          Log.d("gao","" + CustomGiftView.this.getHeight());        }        @Override        public void onAnimationRepeat(Animation animation) { }      });    } else {      for (int i = 0;i < CustomGiftView.this.getChildCount();i ++) {        if (giftView.equals(CustomGiftView.this.getChildAt(i))) {          if (i >= 3) {            CustomGiftView.this.removeView(giftView);          }        }      }//            llgiftcontent.addView(giftView,0);      CustomRoundView crvheadimage = (CustomRoundView) giftView.findViewById(R.id.crvheadimage);      MagicTextView giftNum = (MagicTextView) giftView.findViewById(R.id.giftNum);      int showNum = (Integer) giftNum.getTag() + 1;      giftNum.setText("x"+showNum);      giftNum.setTag(showNum);      crvheadimage.setTag(System.currentTimeMillis());      new NumAnim().start(giftNum);    }  }    public static class NumAnim {    private Animator lastAnimator = null;    public void start(View view) {      if (lastAnimator != null) {        lastAnimator.removeAllListeners();        lastAnimator.end();        lastAnimator.cancel();      }      ObjectAnimator anim1 = ObjectAnimator.ofFloat(view, "scaleX",0.7f, 1.5f,1f);      ObjectAnimator anim2 = ObjectAnimator.ofFloat(view, "scaleY",0.7f, 1.5f,1f);      AnimatorSet animSet = new AnimatorSet();      lastAnimator = animSet;      animSet.setD
