绘制虚线并制作动画

标签： android layout draw lines

我的全屏活动应如下所示：

enter image description here

大白圈会有一些文字，我已经做过，但问题是我不知道如何在图标之间做虚线，他们也想在图标中加一点动画，所以我假设每个人都应该是一个单独的视图，到目前为止我已经完成了这个（它不需要看起来完全一样）：

enter image description here

那么，我怎么画这些线？此外，如果我可以使破折号“运行”，那么线条就会很棒。

这是我的xml：

我如何完成这项工作，我创建了一个包含Canvas控制器的新活动，并将位图放在画布上并用它绘制它们之间的线，我没有使用任何外部库： 希望有人可以重用一些代码，而不仅仅是被告知google它。
