最多显示当前日期的日期选择对话框（日历）

来来来，既然是对话框，我们肯定的继承对话框，废话不多说，直接上代码

R.style.ShareDialog

最后看看怎么使用的吧

1 @Event(R.id.findtime) 2private void onFindTime(View view) { 3 MyDatePickerDialog mDialog = new MyDatePickerDialog(this, true); 4 String sTime = findTime.getText().toString(); 5 if (StringUtils.isEmpty(sTime)) { 6 Calendar mCalendar = Calendar.getInstance(); 7 y = mCalendar.get(Calendar.YEAR); 8 m = mCalendar.get(Calendar.MONTH) + 1; 9 d = mCalendar.get(Calendar.DAY_OF_MONTH);10 }11 mDialog.setDate(y, m, d);12 mDialog.show();13 mDialog.setBirthdayListener(new MyDatePickerDialog.OnBirthListener() {14 @Override15 public void onClick(String year, String month, String day) {16 //清空当前时间17 y = Integer.parseInt(year);18 m = Integer.parseInt(month);19 d = Integer.parseInt(day);20 findTime.setText(year + "-" + month + "-" + day);21 }22 });23}

效果展示

最大时间就是当前时间
