android中Tween动画的监听事件【实现小球在手机屏幕运动一圈】

来源：互联网发布：淘宝开店上传宝贝技巧编辑：程序博客网时间：2024/05/29 06:34

width是手机的宽度；height是手机的高度；

pop_iv是小球球图片；

iv_width是小球的宽度；iv_heigt是晓求得高度；

主要：在每一个动画监听事件的结束方法里写下一个动画，只能点击按钮转一圈，重复旋转这里么有实现；

if（）{}的判断根据自己的要求去改

遇到的问题：

昨天用Tween实现了小球转圈运动，但是在该页面没有重启的时候，小球只保存最后一次if判断的动画效果

TranslateAnimation animation = new TranslateAnimation(0, 0, 0, height - iv_height);animation.setDuration(1000);animation.setFillAfter(true);//动画的监听事件animation.setAnimationListener(new Animation.AnimationListener() {    @Override    public void onAnimationStart(Animation animation) {        //   float x = pop_iv.getX();        float x = pop_iv.getRotationX();        float y = pop_iv.getY();        System.out.println("animation===x的值是：" + x + "+y的值是：" + y);    }    @Override    public void onAnimationEnd(Animation animation) {        if (height - iv_height > 500) {            final TranslateAnimation ani = new TranslateAnimation(0, width - 82, height - iv_height, height - iv_height);            ani.setDuration(1000);            ani.setFillAfter(true);            ani.setAnimationListener(new Animation.AnimationListener() {                @Override                public void onAnimationStart(Animation animation) {                    float x = pop_iv.getX();                    float y = pop_iv.getY();                    System.out.println("ani==x的值是：" + x + "+y的值是：" + y);                }                @Override                public void onAnimationEnd(Animation animation) {                    if (width - iv_width > 200) {                        TranslateAnimation ani1 = new TranslateAnimation(width - 82, width - 82, height - iv_height, 0);                        ani1.setDuration(1000);                        ani1.setFillAfter(true);                        ani1.setAnimationListener(new Animation.AnimationListener() {                            @Override                            public void onAnimationStart(Animation animation) {                                float x = pop_iv.getX();                                float y = pop_iv.getY();                                System.out.println("ani1==x的值是：" + x + "+y的值是：" + y);                            }                            @Override                            public void onAnimationEnd(Animation animation) {                                //      if ((width - iv_width == 82)) {                                TranslateAnimation ani2 = new TranslateAnimation(width - 82, 0, 0, 0);                                ani2.setDuration(1000);                                ani2.setFillAfter(true);                                ani2.setAnimationListener(new Animation.AnimationListener() {                                    @Override                                    public void onAnimationStart(Animation animation) {                                        float x = pop_iv.getX();                                        float y = pop_iv.getY();                                        System.out.println("ani2==x的值是：" + x + "+y的值是：" + y);                                    }                                    @Override                                    public void onAnimationEnd(Animation animation) {                                    }                                    @Override                                    public void onAnimationRepeat(Animation animation) {                                        animation.setRepeatCount(-1);                                    }                                });                                pop_iv.startAnimation(ani2);                            }                            //   }                            @Override                            public void onAnimationRepeat(Animation animation) {                                animation.setRepeatCount(-1);                            }                        });                        pop_iv.startAnimation(ani1);                    }                }                @Override                public void onAnimationRepeat(Animation animation) {                    animation.setRepeatCount(-1);                }            });            pop_iv.startAnimation(ani);        }    }    @Override    public void onAnimationRepeat(Animation animation) {        animation.setRepeatCount(-1);    }});pop_iv.startAnimation(animation);
