重新绘制自定义视图一段时间后，应用程序冻结或软锁定

Question

我写了一个自定义视图来绘制图形，并强制每20毫秒使用一次无效的图形进行重绘。有时，应用程序有时会停止对输入的响应，这非常不稳定。图形将继续绘制，并且在按下按钮时将切换为按下状态，但是它们不会触发onclick方法。此时，如果我退出该应用程序，除非将其杀死，否则将无法再次打开它。

我猜想这是由于重绘所致，因为将重绘计时器减少到每100ms可以使该问题消失（至少从我的测试中消失），但使其更快（10ms）则使其更加一致。

我似乎无法在网上找到有关该产品的任何信息，并且该应用程序也没有崩溃，因此我在Android Studio中没有出现任何错误
