我已经为 android times square 实现了代码，但我无法在月份更改时检测到该事件。 我必须突出显示月份的多个日期范围。

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;
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);
    }
}

json 响应:

看来我错过了什么。任何建议表示赞赏。

最佳答案

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。在我的例子中，我只是检查日期是否在 5 号之前，但您可以在那里进行更有意义的检查 - 例如，提供日期范围并检查给定日期是否在此范围内。

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);
