FATAL EXCEPTION: main
java.lang.NumberFormatException: Invalid long: "2015-03-01"
当您解析任何字符串数字时会引发此异常（即 String stringNumber="09";，其中字符串数字是双引号之间的任何数字，如“09”），而不是数字，例如包含其他字符的字符串数字如果它包含“0-9”、"A09"、"A9"、“”、“9a”、“9-1”等，则在数字中代替“9”或“09”。此异常将扔
您必须避免传递所有其他字符。
您只能将数字作为字符串传递，因此您将获得 int、long 等形式的数字
at com.tgkjer.fertilitystress.CalendarAdapter.getView(CalendarAdapter.java:137)
在 `
中的第 90 行
com.tgkjer.fertilitystress.CalendarAdapter.getView(CalendarAdapter.java:90)
String[] separatedTime = dayString.get(position).split("-");
separatedTime 将具有字符串编号，即 dayString 具有类似于 "2015-03-01" 的日期值，这就是为什么您使用分隔符“-”拆分值的原因“-”
您在
中的第 117 行呼叫
com.tgkjer.fertilitystress.CalendarAdapter.getView(CalendarAdapter.java:117)
// create date string for comparison
String date = dayString.get(position);
所以日期的值为“2015-03-01”
if (date.length() == 1) {
date = "0" + date;
}
上面第 119 到 121 行的代码不会将日期值作为事实，因为 date.length() == 1 是 false 它不会进入 if 块。
现在请参阅
中的第 137 行
com.tgkjer.fertilitystress.CalendarAdapter.getView(CalendarAdapter.java:137)
long date1 = Long.parseLong(date);
此处 Long.parseLong() 期望值类似于字符串编号，但得到的日期值为字符串“2015-03-01”，因此出现异常。
所以在
这样的日期使用你的拆分函数
String[] separatedyyMMdd = date.split("-");
long date1yy = Long.parseLong(separatedyyMMdd[0]);
long date1mm = Long.parseLong(separatedyyMMdd[1]);
long date1dd = Long.parseLong(separatedyyMMdd[2]);
它将解决您的上述问题

“这就是我 logcat 中的错误 你能帮我指出错误在哪里吗 在我的代码中？
预期输出：我想根据周期的计算突出显示多天
FATAL EXCEPTION: main
java.lang.NumberFormatException: Invalid long: "2015-03-01"
当您解析任何字符串数字时会引发此异常（即 String stringNumber="09";，其中字符串数字是双引号之间的任何数字，如“09”），而不是数字，例如包含其他字符的字符串数字如果它包含“0-9”、"A09"、"A9"、“”、“9a”、“9-1”等，则在数字中代替“9”或“09”。此异常将扔
您必须避免传递所有其他字符。
您只能将数字作为字符串传递，因此您将获得 int、long 等形式的数字

在 `
中的第 90 行com.tgkjer.fertilitystress.CalendarAdapter.getView(CalendarAdapter.java:90)
String[] separatedTime = dayString.get(position).split("-");
separatedTime 将具有字符串编号，即 dayString 具有类似于 "2015-03-01" 的日期值，这就是为什么您使用分隔符“-”拆分值的原因“-”
您在
中的第 117 行呼叫com.tgkjer.fertilitystress.CalendarAdapter.getView(CalendarAdapter.java:117)
// create date string for comparison
String date = dayString.get(position);
所以日期的值为“2015-03-01”
if (date.length() == 1) {
date = "0" + date;
}
上面第 119 到 121 行的代码不会将日期值作为事实，因为 date.length() == 1 是 false 它不会进入 if 块。
现在请参阅
中的第 137 行com.tgkjer.fertilitystress.CalendarAdapter.getView(CalendarAdapter.java:137)
long date1 = Long.parseLong(date);
此处 Long.parseLong() 期望值类似于字符串编号，但得到的日期值为字符串“2015-03-01”，因此出现异常。 所以在
这样的日期使用你的拆分函数String[] separatedyyMMdd = date.split("-");
long date1yy = Long.parseLong(separatedyyMMdd[0]);
long date1mm = Long.parseLong(separatedyyMMdd[1]);
long date1dd = Long.parseLong(separatedyyMMdd[2]);
它将解决您的上述问题
