android中Tween动画的监听事件【实现小球在手机屏幕运动一圈】

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() {

                    float y = pop_iv.getY();
