可以点击进去查看实现过程 纵享丝滑滑动切换的周月日历，水滴效果，丰富自定义日历样式，仿小米日历
之前开发任务中有涉及到年月日日历的切换效果，由于是需要联动，想到的方向大概有3种，要么通过处理view的touch事件，要么是通过自定义behavior去实现，要么是通过ViewDragHelper这个神器去实现，网上比较多的是通过自定义bahavior去实现，本文使用的是第三种方法，实现的是一个可高度定制自由切换的周月日历视图,提供一种思路去实现页面联动效果。
- 可以控制是否允许左右滑动，上下滑动，切换年月
- 流畅的上下周月模式切换
- 允许选择农历和普通日历
- 丰富自定义日历样式
- 设置每周的第一天
- 设置某一天不允许选中
- 基于material-calendarview 这个库实现，可以下载源码根据需求定制效果
支持grid and staggeredgrid layoutManager

- 底部的recyclerView的layoutManager要实现ILayoutManager接口，设置是否允许上下滑动， 例如示例中的CustomLinearLayoutManager.java
monthWeekMaterialCalendarView.setCurrentDate(selectedDate);
monthWeekMaterialCalendarView.setSelectedDate(selectedDate)
monthWeekMaterialCalendarView.addDecorator(new EventDecorator(Color.RED, dates))
monthWeekMaterialCalendarView.removeDecorators();
monthWeekMaterialCalendarView.setMode(MonthWeekMaterialCalendarView.Mode.MONTH)
monthWeekMaterialCalendarView.goToPrevious();
monthWeekMaterialCalendarView.goToNext();
monthWeekMaterialCalendarView.setCanDrag
monthWeekMaterialCalendarView.setPagingEnabled
monthWeekMaterialCalendarView.state().edit()
//设置最大最小日期
.setMinimumDate(new CalendarDay(2017,1,1))
.setMaximumDate(new CalendarDay(2018,3,1))
.setSlideModeChangeListener(new MonthWeekMaterialCalendarView.SlideModeChangeListener() {
@Override
public void modeChange(MonthWeekMaterialCalendarView.Mode mode) {
}
}).setSlideDateSelectedlistener(new MonthWeekMaterialCalendarView.SlideDateSelectedlistener() {
@Override
public void onDateSelected(@NonNull MaterialCalendarView widget, @NonNull CalendarDay date, boolean selected) {
}
}).setSlideOnMonthChangedListener(new MonthWeekMaterialCalendarView.SlideOnMonthChangedListener() {
@Override
public void onMonthChanged(MaterialCalendarView widget, CalendarDay date) {
}
}).commit();monthWeekMaterialCalendarView.setSelectionColor
因为基于MaterialCalendarView的周和月视图组成的，所以可以在XML中设置选中颜色，字体样式等等
<com.prolificinteractive.materialcalendarview.MaterialCalendarView
android:id="@+id/calendarView_month_mode"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:mcv_selectionColor="@color/colorPrimary"
app:mcv_dateTextAppearance="@style/TextAppearance.MaterialCalendarWidget.Date"
app:mcv_calendarMode="month"
app:mcv_showOtherDates="defaults|other_months"
app:mcv_showWeekView="false" />
<com.prolificinteractive.materialcalendarview.MaterialCalendarView
android:id="@+id/calendarView_week_mode"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="@android:color/white"
android:visibility="invisible"
app:mcv_selectionColor="@color/colorPrimary"
app:mcv_dateTextAppearance="@style/TextAppearance.MaterialCalendarWidget.Date"
app:mcv_calendarMode="week"
app:mcv_showTopBar="false"
app:mcv_showWeekView="false" />如果你想给单独的日期视图设置一些样式的话，例如周末右上角有个图标这样子的需求之类的话，你可以写一个类继承自DayViewDecorator
public class RemindDecorator implements DayViewDecorator {
private final Calendar calendar = Calendar.getInstance();
private Context context;
public RemindDecorator(Context context) {
this.context=context;
}
@Override
public boolean shouldDecorate(CalendarDay day) {
day.copyTo(calendar);
int weekDay = calendar.get(Calendar.DAY_OF_WEEK);
return weekDay == Calendar.SATURDAY || weekDay == Calendar.SUNDAY;
}
@Override
public void decorate(DayViewFacade view) {
view.addSpan(new RestSpan(context));
}
}- shouldDecorate()这个方法是判断是否需要添加Decorator的条件
- decorate()这个方法可以对显示样式做一些操作
DayViewFacade 可以通过setSelectionDrawable()，setBackgroundDrawable(),addSpan()设置样式，尤其是addSpan的方法，因为你传进去的是一个span,所以你可以在里面做很多自定义样式的操作，例如 RestSpan.java周末右上角加个图标。
接下来说下你可以怎么去定制？如果你想替换项目中的月和周视图的话，很简单，
只需要你自己的周月视图必须有一个方法获得单行日历的高度(例如我的库中的MaterialCalendarView.getItemHeight() )，
然后把这个月视图和周视图，分别在MonthWeekMaterialCalendarView里面按照顺序放到对应位置即可。
然后再setListener()里面设置相关的回调处理，例如日期选中或者月份切换的回调等。
