TimePickerView
功能介绍
1.支持YMDHMS,YMD,HMS,HM常用类型时间显示
2.支持过去时间过滤，不显示出来
3.支持设置当前默认显示时间
4.功能与UI分离，支持样式扩展

功能实现说明
1.通过initDisplayMode方法，初始化显示模式，在初始化TimePickerView对象后设置

timePickerView = new TimePickerView(MainActivity.this);  
timePickerView.setMode(TimePickerView.DISPLAY_HM);

2.在弹出时间控件前，会根据设置判断，通过initPickViewDisplayData方法设置年月日时分秒的显示数据

//初始化显示数据  
private void initPickViewDisplayData(){  
    try {  
        if(StringUtil.isEmpty(displayTime)){  
            pvw_year.setSelected(0);  
            pvw_month.setSelected(0);  
            pvw_day.setSelected(0);  
            pvw_hour.setSelected(0);  
            pvw_minute.setSelected(0);  
            pvw_second.setSelected(0);  
            select_year = pvw_year.getSelected();  
            select_month = pvw_month.getSelected();  
            select_day = pvw_day.getSelected();  
            select_hour = pvw_hour.getSelected();  
            select_minute = pvw_minute.getSelected();  
            select_second = pvw_second.getSelected();  
        }else{  
            Date date = DateUtil.str2Date(displayTime, mode);  
            Calendar calendar = Calendar.getInstance();  
            calendar.setTime(date);  
            select_year = DateUtil.getYear(startTime, DateUtil.PATTERN_ALL)+"";  
            select_month = DecimalUtil.keep2zero_head(DateUtil.getMonth(startTime, DateUtil.PATTERN_ALL)+"");  
            select_day = DecimalUtil.keep2zero_head(DateUtil.getDay(startTime, DateUtil.PATTERN_ALL)+"");  
            select_hour = DecimalUtil.keep2zero_head(DateUtil.getHour(startTime, DateUtil.PATTERN_ALL)+"");  
            select_minute = DecimalUtil.keep2zero_head(DateUtil.getMinute(startTime, DateUtil.PATTERN_ALL)+"");  
            select_second =DecimalUtil.keep2zero_head(DateUtil.getSecond(startTime, DateUtil.PATTERN_ALL)+"");  
            switch (mode) {  
            case DISPLAY_YMDHMS://yyyy-MM-dd HH:mm:ss  
                select_year = calendar.get(Calendar.YEAR)+"";  
                select_month = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.MONTH)+1));  
                select_day = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.DATE)));  
                select_hour = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.HOUR_OF_DAY)));  
                select_minute = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.MINUTE)));  
                select_second =DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.SECOND)));  
                initData();  
                pvw_year.setSelected(select_year);  
                pvw_month.setSelected(select_month);  
                pvw_day.setSelected(select_day);  
                pvw_hour.setSelected(select_hour);  
                pvw_minute.setSelected(select_minute);  
                pvw_second.setSelected(select_second);  
                break;  
            case DISPLAY_YMD://yyyy-MM-dd  
                select_year = calendar.get(Calendar.YEAR)+"";  
                select_month = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.MONTH)+1));  
                select_day = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.DATE)));  
                initData();  
                pvw_year.setSelected(select_year);  
                pvw_month.setSelected(select_month);  
                pvw_day.setSelected(select_day);  
                break;  
            case DISPLAY_HMS://HH:mm:ss  
                select_hour = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.HOUR_OF_DAY)));  
                select_minute = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.MINUTE)));  
                select_second =DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.SECOND)));  
                initData();  
                pvw_hour.setSelected(select_hour);  
                pvw_minute.setSelected(select_minute);  
                pvw_second.setSelected(select_second);  
                break;  
            case DISPLAY_HM://HH:mm:ss  
                select_hour = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.HOUR_OF_DAY)));  
                select_minute = DecimalUtil.keep2zero_head(""+(calendar.get(Calendar.MINUTE)));  
                initData();  
                pvw_hour.setSelected(select_hour);  
                pvw_minute.setSelected(select_minute);  
                break;  
            default:  
                break;  
            }  
        }  
    } catch (Exception e) {  
        // TODO: handle exception  
    }  
}  

3.初始化时间数据的时候，通过调用initData方法初始年月日时分秒滚动组件的数据集合

//初始日  
private void initDay(boolean isSlide){  
int start_day = DateUtil.getDay(startTime, DateUtil.PATTERN_ALL);  
int day_of_month = DateUtil.getDayOfMonth(startTime,DateUtil.PATTERN_ALL);  
int start_year =  DateUtil.getYear(startTime, DateUtil.PATTERN_ALL);  
int start_month =  DateUtil.getMonth(startTime, DateUtil.PATTERN_ALL);  
String select_time = select_year + "-" + select_month;  
String start_time = start_year + "-" + DecimalUtil.keep2zero_head(start_month + "");  
//判断当前选择时间是否是开始时间  
if (!select_time.equals(start_time)) {  
start_day = 1;  
}  
String now_time = select_year + "-" + select_month + "-01 00:00:00";  
day_of_month = DateUtil.getDayOfMonth(now_time, DateUtil.PATTERN_ALL);  
day_list.clear();  
for(int i=start_day;i<=day_of_month;i++){  
day_list.add(DecimalUtil.keep2zero_head(i+""));  
}  
//滑动时执行  
if(isSlide){  
pvw_day.invalidate();  
pvw_day.setSelected(0);  
select_day = pvw_day.getSelected();  
excuteAnimator(ANIMATORDELAY, pvw_day);  
pvw_day.postDelayed(new Runnable() {  
@Override  
public void run() {  
initHour(true);  
}  
}, CHANGEDELAY);  
}  
}
