在 android 时代广场的月份滚动时检测侦听器
Detect listener on month scrolling in android times square
我已经为 android times square 实现了代码，但是我无法在月份更改时检测到该事件。 I have to highlight multiple range of dates from months。
这是我的做法，但是，我无法在滚动时检测到月份何时更改
代码：
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;

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() {

@Override

calender1.init(lastYear.getTime(), nextYear.getTime());//.inMode(SelectionMode.RANGE);
new MyAsyncTask(BOOKING_URL).execute();

使用 CalendarCellDecorator 你可以这样写：
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 天的背景与其余几天不同。每个月的每个单元格都会通过装饰器，因此您可以使用它来更改多个月的 UI 个单元格。
通常，您必须存储应突出显示 CalendarCellDecorator 的日期，并在 decorate 方法中检查给定的 cellView 是否显示这些日期之一。在我的例子中，我只是检查日期是否在 5 号之前，但是你可以在那里进行更有意义的检查——例如，给出一个日期范围并检查给定日期是否在这个范围内。
编辑：显示如何应用装饰器：
calendar.init(lastYear.toDate(), nextYear.toDate()).inMode(CalendarPickerView.SelectionMode.RANGE);
List<CalendarCellDecorator> decoratorList = new ArrayList<>();
decoratorList.add(new MonthDecorator());
calendar.setDecorators(decoratorList);
