看来我错过了一些东西。
解决方案
使用 CalendarCellDecorator 像这样：
public class MonthDecorator实现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）;
}
}
}
每个月的前5天将有不同于其他日子的背景。每个月的每个单元格都通过装饰器，所以你可以使用它来改变单元格的UI在多个月。
一般来说，你必须存储应该突出显示的日期 CalendarCellDecorator 和装饰方法检查指定的cellView是否显示这些日期中的一个。在我的情况下，我只是检查日期是否在5之前，但你可以做一个更有意义的检查，即给一个范围的日期，并检查给定的日期是否在这个范围内，例如
编辑：显示如何应用装饰：
calendar.init（lastYear.toDate nextYear.toDate（））。inMode（
CalendarPickerView.SelectionMode.RANGE）;
List< CalendarCellDecorator> decoratorList = new ArrayList<>（）;
decoratorList.add（new MonthDecorator（））;
calendar.setDecorators（decoratorList）;
I have implemented code for android times square, but I am unable to detect the event when the month change. I have to highlight multiple range of dates from months.
This is the way I have done but, I am unable to detect when month got changed while scrolling
code:
public class Calender extends Activity implements OnDateChangeListener,CalendarCellDecorator {
String BOOKING_URL="http://www.example.com/app/webroot/mobile/booking.php";
ArrayList<String>list=new ArrayList<String>();
CalendarPickerView calender;
ArrayList<Date> dates = new ArrayList<Date>();
Calendar lastYear,nextYear;
Calendar today;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.calender);
getActionBar().setTitle("CALENDER");
getActionBar().setIcon(R.drawable.back);
getActionBar().setDisplayOptions(getActionBar().getDisplayOptions()| ActionBar.DISPLAY_SHOW_CUSTOM);
ImageView imageView = new ImageView(getActionBar().getThemedContext());
imageView.setScaleType(ImageView.ScaleType.CENTER);
imageView.setImageResource(R.drawable.manu_btn);
ActionBar.LayoutParams layoutParams = new ActionBar.LayoutParams(ActionBar.LayoutParams.WRAP_CONTENT,ActionBar.LayoutParams.WRAP_CONTENT, Gravity.RIGHT| Gravity.CENTER_VERTICAL);
layoutParams.rightMargin = 40;
imageView.setLayoutParams(layoutParams);
getActionBar().setCustomView(imageView);
centerActionBarTitle();
imageView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
nextYear = Calendar.getInstance();
nextYear.add(Calendar.YEAR, 2);
lastYear= Calendar.getInstance();
lastYear.add(Calendar.YEAR, -2);
today = Calendar.getInstance();
calender = (CalendarPickerView) findViewById(R.id.calendar);
calender.setOnScrollListener(new OnScrollListener() {
private int mLastFirstVisibleItem;
@Override
public void onScrollStateChanged(AbsListView view, int scrollState) {
}
@Override
public void onScroll(AbsListView view, int firstVisibleItem,
int visibleItemCount, int totalItemCount) {
if(mLastFirstVisibleItem<firstVisibleItem)
{
Log.d("SCROLLING DOWN","TRUE");
}
if(mLastFirstVisibleItem>firstVisibleItem)
{
Log.d("SCROLLING UP","TRUE");
}
mLastFirstVisibleItem=firstVisibleItem;
}
});
calender1.init(lastYear.getTime(), nextYear.getTime());//.inMode(SelectionMode.RANGE);
new MyAsyncTask(BOOKING_URL).execute();
}
.....
try {
JSONArray array=new JSONArray(response);
for (int i = 0; i < array.length(); i++) {
JSONObject json=array.getJSONObject(i);
list.add(json.getString("fromDate")+" "+json.getString("toDate"));
}
SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd");
TimeZone gmt = TimeZone.getTimeZone("GMT");
sdf.setTimeZone(gmt);
sdf.setLenient(false);
try {
Date date = sdf.parse(list.get(0).split(" ")[0]);
Date date1 = sdf.parse(list.get(0).split(" ")[1]);
System.out.println(date);
dates.add(date);
dates.add(date1);
} catch (Exception e) {
e.printStackTrace();
}
calendar.init(lastYear.getTime(), nextYear.getTime()).inMode(SelectionMode.RANGE).withSelectedDates(dates);
} catch (JSONException e) {
e.printStackTrace();
}
....
@Override
public void decorate(CalendarCellView calendarCellView, Date date) {
Log.d("TAG", "a"+date);
if (date.getDate() < 5) {
calendarCellView.setBackgroundResource(R.drawable.side_testi);
} else {
calendarCellView.setBackgroundResource(R.drawable.side_book);
}
}

It seems I am missing something. Any suggestion is appreciated.
解决方案
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);
}
}
}
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.
EDIT: showing how to apply the decorator:
calendar.init(lastYear.toDate(), nextYear.toDate()).inMode(
CalendarPickerView.SelectionMode.RANGE);
List<CalendarCellDecorator> decoratorList = new ArrayList<>();
decoratorList.add(new MonthDecorator());
calendar.setDecorators(decoratorList);
