layoutParams.rightMargin = 40;
imageView.setLayoutParams(layoutParams);
getActionBar().setCustomView(imageView);
centerActionBarTitle();
imageView.setOnClickListener(new OnClickListener() {
@Override

});
nextYear = Calendar.getInstance();
nextYear.add(Calendar.YEAR, 2);

lastYear.add(Calendar.YEAR, -2);
today = Calendar.getInstance();
calender = (CalendarPickerView) findViewById(R.id.calendar);
calender.setOnScrollListener(new OnScrollListener() {

});
calender1.init(lastYear.getTime(), nextYear.getTime());//.inMode(SelectionMode.RANGE);

}

It seems I am missing something. Any suggestion is appreciated.
推荐答案
使用 CalendarCellDecorator 你可以这样写:
Using the CalendarCellDecorator you could write something like this:
public class MonthDecorator implements CalendarCellDecorator {
@Override
public void decorate(CalendarCellView calendarCellView, Date date) {
if (date.getDate() < 5) {
calendarCellView.setBackgroundResource(R.drawable.red_background);
} else {
calendarCellView.setBackgroundResource(R.drawable.blue_background);
}
}
}
这是一个简单的示例 - 每个月的前 5 天与其余天的背景不同.每个月的每个单元格都会通过装饰器，因此您可以使用它在多个月内更改单元格的 UI.通常，您必须存储应突出显示的日期 CalendarCellDecorator 并在 decorate 方法中检查给定的 cellView 是否显示这些日期之一.就我而言，我只是检查日期是否在 5 日之前，但您可以在那里进行更有意义的检查 - 例如，给出日期范围并检查给定日期是否在此范围内.
It is a simple example - the first 5 days in every month will have a different background than the rest of the days. Every cell in every month passes through the decorator, so you could use it to change the UI of cells in multiple months.
Generally you'll have to store the dates which should be highlighted CalendarCellDecorator and in the decorate method check whether the given cellView is showing one of these dates. In my case I just check whether the date is before 5th, but you could make a more meaningful check there - i.e. give a range of dates and check whether the given date is inside this range for example.
展示如何应用装饰器:
calendar.init(lastYear.toDate(), nextYear.toDate()).inMode(CalendarPickerView.SelectionMode.RANGE);
List<CalendarCellDecorator> decoratorList = new ArrayList<>();
decoratorList.add(new MonthDecorator());
calendar.setDecorators(decoratorList);
