最近找了几个日历的控件，忙活半天发现有的不是很好用比如CompactCalendarView，发现EasyCalendar还可以，应该挺好用的。使用也很方便

Android 日历（EasyCalendar）_数据

1、添加依赖

https://github.com/shichaohui/EasyCalendar

compile 'com.sch.calendar:easy-calendar:1.0.0'

2、布局

com.sch.calendar.CalendarView
        android:id="@+id/easy_calendar"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:background="@drawable/checkin_calendar_bg"
        android:padding="10dp"
        app:titleColor="@color/colorPrimaryDark"
        app:monthBackground="@drawable/checkin_calendar_month_bg"
        app:weekBackground="#FFFFFF"
        app:weekColor="#000000"
        >
    </com.sch.calendar.CalendarView>

3、使用
（1）初始化

private void initCalendar() {
        mCalendarView.setCanDrag(true);//可拖动
        mCalendarView.setScaleEnable(false);//不可伸缩
        mCalendarView.setShowOverflowDate(true);
        mCalendarView.setCanFling(true);
//        mCalendarView.setBackgroundColor(getResources().getColor(R.color.colorAccent));

        mCalendarView.setOnMonthChangedListener(new OnMonthChangedListener() {
            @Override
            public void onMonthChanged(Date date) {
                //月份变化
            }
        });
        mCalendarView.setOnDateClickedListener(new OnDateClickedListener() {
            @Override
            public void onDateClicked(View itemView, int year, int month, int dayOfMonth) {
                //日期点击，可以弹出日期或者是否签到，看需求
            }
        });
        //adapter是必须设置的不然不显示日期，
        //设置的布局是日期的布局，数据是用于签到的
        vagueAdapter = new MyVagueAdapter(R.layout.layout_checkin_calendar_item);
        vagueAdapter.setData(new

（2）根据data判断是否显示签到的对号（imgview）

class MyVagueAdapter extends VagueAdapter<Map<String, Map<String, Checkin>>> {

        /**
         * Initialization adapter.
         *
         * @param
        public MyVagueAdapter(@LayoutRes int dayLayout) {
            super(dayLayout);
        }

        @Override
        public void onBindVague(View itemView, int year, int month, int dayOfMonth) {
            ImageView ivCheckinAlready = (ImageView) itemView.findViewById(R.id.iv_checkin_already);
            if (data == null) return;
            //获取当月数据
            Map<String, Checkin> monthMap = data.get(DateUtil.formatDate(year, month, dayOfMonth, MONTH_FORMAT));
            //无当月数据
            if (monthMap == null) {
                ivCheckinAlready.setVisibility(View.GONE);
                return;
            }
            Checkin history = monthMap.get(DateUtil.formatDate(year, month, dayOfMonth, DAY_OF_MONTH_FORMAT));
            ivCheckinAlready.setVisibility(history == null ? View.GONE : View.VISIBLE);
        }

        @Override
        public void flagToday(View todayView) {
            //标记今天
            TextView tvDayView = (TextView) todayView.findViewById(R.id.tv_day_of_month);
            tvDayView.setBackgroundResource(R.mipmap.checkin_calendar_ic_today_flag);
            tvDayView.setTextColor(Color.WHITE);
        }

        @Override
        public void flagNotToday(View dayView, Date date) {
        //设置非今天的文本颜色

（3）造签到数据

private Map<String, Map<String, Checkin>> createCheckinData() {
        Map<String, Map<String, Checkin>> checkinMap = new HashMap<>();
        Map<String, Checkin> monthCheckinMap = new HashMap<>();
        Date today = DateUtil.today();
        int year = today.getYear();
        int month = today.getMonth();
        int dayofmonth = today.getDayOfMonth();
        checkinMap.put(DateUtil.formatDate(year, month, dayofmonth, MONTH_FORMAT), monthCheckinMap);
        for (int i = 1, N = today.getDayOfMonth() - 1; i < N; i++) {
            if (i % 3 == 0) {
                monthCheckinMap.put(DateUtil.formatDate(year, month, dayofmonth + 1, DAY_OF_MONTH_FORMAT), new

（4）是否签到直接插入数据，更新即可

public void sign(View view) {
        Date today = DateUtil.today();
        int year = today.getYear();
        int month = today.getMonth();
        int dayOfMonth = today.getDayOfMonth();
        Map<String, Checkin> checkinMap = vagueAdapter.getData().get(DateUtil.formatDate(year, month, dayOfMonth, MONTH_FORMAT));
        if (checkinMap == null) return;
        checkinMap.put(DateUtil.formatDate(year, month, dayOfMonth, DAY_OF_MONTH_FORMAT), new Checkin());
        vagueAdapter.notifyDataSetChanged();
        view.setEnabled(false);
        ((Button) view).setText("已签到");
    }

4、最后完整

public class EasyCalendarActivity extends AppCompatActivity {
    private CalendarView mCalendarView;
    private final String MONTH_FORMAT = "yyyyMM";
    private final String DAY_OF_MONTH_FORMAT = "yyyyMMdd";
    private VagueAdapter<Map<String, Map<String, Checkin>>> vagueAdapter;

    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_easyui);
        mCalendarView = (CalendarView) findViewById(R.id.easy_calendar);
        initCalendar();
        mCalendarView.post(new Runnable() {
            @Override
            public void run() {
                vagueAdapter.setData(createCheckinData());
                vagueAdapter.notifyDataSetChanged();
            }
        });

    }

    private Map<String, Map<String, Checkin>> createCheckinData() {
        Map<String, Map<String, Checkin>> checkinMap = new HashMap<>();
        Map<String, Checkin> monthCheckinMap = new HashMap<>();
        Date today = DateUtil.today();
        int year = today.getYear();
        int month = today.getMonth();
        int dayofmonth = today.getDayOfMonth();
        checkinMap.put(DateUtil.formatDate(year, month, dayofmonth, MONTH_FORMAT), monthCheckinMap);
        for (int i = 1, N = today.getDayOfMonth() - 1; i < N; i++) {
            if (i % 3 == 0) {
                monthCheckinMap.put(DateUtil.formatDate(year, month, dayofmonth + 1, DAY_OF_MONTH_FORMAT), new Checkin());
            }
        }
        return checkinMap;
    }

    public void sign(View view) {
        Date today = DateUtil.today();
        int year = today.getYear();
        int month = today.getMonth();
        int dayOfMonth = today.getDayOfMonth();
        Map<String, Checkin> checkinMap = vagueAdapter.getData().get(DateUtil.formatDate(year, month, dayOfMonth, MONTH_FORMAT));
        if (checkinMap == null) return;
        checkinMap.put(DateUtil.formatDate(year, month, dayOfMonth, DAY_OF_MONTH_FORMAT), new Checkin());
        vagueAdapter.notifyDataSetChanged();
        view.setEnabled(false);
        ((Button) view).setText("已签到");
    }

    private void initCalendar() {
        mCalendarView.setCanDrag(true);//可拖动
        mCalendarView.setScaleEnable(false);//不可伸缩

        mCalendarView.setCanFling(true);
//        mCalendarView.setBackgroundColor(getResources().getColor(R.color.colorAccent));

        mCalendarView.setOnMonthChangedListener(new OnMonthChangedListener() {

            @Override

                //日期点击

            }
        });
        vagueAdapter = new MyVagueAdapter(R.layout.layout_checkin_calendar_item);
        vagueAdapter.setData(new HashMap<String, Map<String, Checkin>>());
        mCalendarView.setVagueAdapter(vagueAdapter);
    }

        /**
         * Initialization adapter.
         *
         * @param dayLayout layout for day of month
         */
        public MyVagueAdapter(@LayoutRes int dayLayout) {
            super(dayLayout);
        }

        @Override
        public void onBindVague(View itemView, int year, int month, int dayOfMonth) {
            ImageView ivCheckinAlready = (ImageView) itemView.findViewById(R.id.iv_checkin_already);
            if (data == null) return;

                return;
            }
            Checkin history = monthMap.get(DateUtil.formatDate(year, month, dayOfMonth, DAY_OF_MONTH_FORMAT));

        }
