为什么我的android约束集动画的行为不一致？

Question

我正在创建一个动画，它将在两个不同活动之间的按钮按下时运行。它将从第一个活动开始向前运行，然后自动启动第二个活动，反之亦然（从第二个活动到第一个活动相反）。

我已经成功地使动画独立运行，但是当我介绍链接的活动时，它会间歇性地错误移动。两个气泡在向上移动（或向后移动）时，其大小应增大，但是有时它们会增大，但无法向上移动。

我完全是自学成才的，并且刚接触编码，所以请您原谅任何可怕的失误。指导表示赞赏。

这是我的布局：

MainActivity代码：

    ConstraintSet constraintSet;
    boolean goBack;
    String TAG = "debug";

    int animationDuration = 2000;

    }

Activity1和Activity2只是空白屏幕，上面带有buttonAnimate。
