        Canvas.drawpath(path, paint);

Answer 1

这一行做了什么：

data[i];

上面一行也使它无效！

int i;

Answer 2

int i;很好，虽然没有意义，数据[i];抛出一个错误，因为你没有声明任何东西，或者分配任何值，或者真的在那条线上做任何事情，就是这样。无论哪种方式，它可能只是lint，无论如何都在抱怨它。我把Lint检查关闭，直到我导出，因为它总是似乎无所事事。

Answer 3

你不需要这一行：data [i]，短数组的元素默认初始化为0.

语法错误，插入“AssignmentOperator Expression”以完成表达式
