Question

我正在开发一个应用程序，它需要获取当前星期和当前时间来根据日期和日期更改整数。

我已经做到了这一点，但我遇到了一些问题：它在周二中午冻结。它给了我这个::

Unexpected constant; 
expected one of: Calendar.FRIDAY, Calendar.MONDAY, Calendar.SATURDAY, Calendar.SUNDAY, Calendar.THURSDAY, Calendar.TUESDAY, Calendar.WEDNESDAY less...
This check warns if a switch statement does not explicitly include all the 
values declared by the typedef @IntDef declaration.

而且我不知道如何解决它。

有我的代码：当我写这篇文章时，除星期二外它有效：

int countuser = 0;
                int day = Calendar.getInstance().get(Calendar.DAY_OF_WEEK);
                int timeOfDay = Calendar.getInstance().get(Calendar.HOUR_OF_DAY);

                switch (day) {
                    case Calendar.FRIDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 0;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 1;
                        }
                        break;
                    case Calendar.MONDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 2;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 3;
                        }
                        break;
                    case Calendar.SATURDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 4;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 5;
                        }
                        break;
                    case Calendar.SUNDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 6;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 7;
                        }
                        break;
                    case Calendar.THURSDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 8;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 9;
                        }
                        break;
                    case Calendar.TUESDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 10;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 11;
                        }
                        break;
                    case Calendar.WEDNESDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 12;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 13;
                        }
                        break;
                }

但是我想根据当天对countuser进行排序，所以我做了这个，但它冻结了我的应用程序：

switch (day) {
                    case Calendar.FRIDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 8;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 9;
                        }
                        break;
                    case Calendar.MONDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 0;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 1;
                        }
                        break;
                    case Calendar.SATURDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 10;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 11;
                        }
                        break;
                    case Calendar.SUNDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 12;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 13;
                        }
                        break;
                    case Calendar.THURSDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 6;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 7;
                        }
                        break;
                    case Calendar.TUESDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 2;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 3;
                        }
                        break;
                    case Calendar.WEDNESDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 4;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 5;
                        }
                        break;
                }

同样的，当我尝试排序＆＃34;案例Calendar.MONDAY＆＃34;：

 switch (day) {
                    case Calendar.MONDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 0;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 1;
                        }
                        break;
                    case Calendar.TUESDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 2;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 3;
                        }
                        break;
                    case Calendar.WEDNESDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 4;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 5;
                        }
                        break;

                    case Calendar.THURSDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 6;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 7;
                        }
                        break;
                    case Calendar.FRIDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 8;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 9;
                        }
                        break;

                    case Calendar.SATURDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 10;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 11;
                        }
                        break;
                    case Calendar.SUNDAY:
                        if (timeOfDay > 22 || timeOfDay < 16) {
                            countuser = 12;
                        } else if (timeOfDay >= 16 || timeOfDay <= 22) {
                            countuser = 13;
                        }


                }

那么我该如何才能获得当前一周的时间来更改整数的值？我尝试了很多东西，但要么冻结，要么它整天都不起作用......

非常感谢。

我没有足够的回复评论，但你可以发布你的进口吗？并尝试将其放入try-catch块中。

编辑：

try-catch块将尝试捕获您的代码可能抛出的异常。
