推荐答案

Range datepicker 使用了错误的 DateAdapter 范围策略.

Range datepicker uses range strategy with wrong DateAdapter.

为了修复它，您应该在您提供自定义 DateAdapter 的同一级别上提供 MAT_DATE_RANGE_SELECTION_STRATEGY 令牌:

In order to fix it you should provide MAT_DATE_RANGE_SELECTION_STRATEGY token on the same level where you provided custom DateAdapter:

import {
  MAT_DATE_RANGE_SELECTION_STRATEGY,
  DefaultMatCalendarRangeStrategy
} from '@angular/material/datepicker';
...
providers: [
 { provide: MAT_DATE_RANGE_SELECTION_STRATEGY, useClass: DefaultMatCalendarRangeStrategy},
 { provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE]},
 ....

它确保 DefaultMatCalendarRangeStrategy 类将 MomentDateAdapter 作为 DateAdapter 实现而不是 NativeDateAdapter

It makes sure that DefaultMatCalendarRangeStrategy class will get MomentDateAdapter as a DateAdapter implementation instead of NativeDateAdapter
