1、效果图（两个DatePicker放在一起，同时选择起始与结束时间）：
2、实现
2.1布局文件：

2.3调用
在其他类中：
实现DoubleDatePickerDialog 中接口OnDateSetListener中的方法，以完成相应操作
1 //取时间区间 2 private void confirmTimeSpace() { 5 Calendar c=Calendar.getInstance(); 6 new DoubleDatePickerDialog(ScrapedListActivity.this, 0, new DoubleDatePickerDialog.OnDateSetListener() { 7 @Override 8 public void onDateSet(DatePicker startDatePicker, int startYear, int startMonthOfYear, int startDayOfMonth, 9 DatePicker endDatePicker, int endYear, int endMonthOfYear, int endDayOfMonth) {
//取起始结束时间 10 startTimeStr = startYear + SPACE_STR + (startMonthOfYear+1) + SPACE_STR + startDayOfMonth; 11 endTimeStr = endYear + SPACE_STR + (endMonthOfYear+1) + SPACE_STR + endDayOfMonth; 12 13 tstartTimeStr=startYear + TSPACE_STR + (startMonthOfYear+1) + TSPACE_STR + startDayOfMonth; 14 tendTimeStr=endYear + TSPACE_STR + (endMonthOfYear+1) + TSPACE_STR + endDayOfMonth;
//要做的事 15 ScrapedListActivity.this.finish(); 16 } 17 @Override 18 public void onConfirmed(DatePicker startDatePicker, int startYear, int startMonthOfYear, int startDayOfMonth, 19 DatePicker endDatePicker, int endYear, int endMonthOfYear, int endDayOfMonth) {

27 //要做的事 28 initInfoEvent(); 29 } 30 }, c.get(Calendar.YEAR), c.get(Calendar.MONTH), c.get(Calendar.DATE), true).show(); 31 }
