Question

如何在adapter里调用显示日期控件

Answer 1

参考代码：

/**

	 * 弹出日期对话框

	 * @param textView

	 * @param date 默认日期

	 */

	public void showDateDialog(TextView textView, String date) {

		txtDatePicker = textView;

		calendar = Calendar.getInstance();

		if (!toolUtil.isBlank(date)) {

			try {calendar.setTime(dateUtil.formatDate().parse(date));} catch (Exception e) {}

		}

		new DatePickerDialog(this, new DatePickerDialog.OnDateSetListener() {

			public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {

				calendar.set(Calendar.YEAR, year);

				calendar.set(Calendar.MONTH, monthOfYear);

				calendar.set(Calendar.DAY_OF_MONTH, dayOfMonth);

				txtDatePicker.setText(dateUtil.formatDate().format(calendar.getTime()));

			}

		}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH), calendar.get(Calendar.DAY_OF_MONTH)).show();

	}

	

	/**

	 * 弹出时间对话框

	 * @param textView

	 */

	public void showTimeDialog(TextView textView) {

		txtDatePicker = textView;

		new TimePickerDialog(this, new TimePickerDialog.OnTimeSetListener() {

			public void onTimeSet(TimePicker view, int hourOfDay, int minute) {

				calendar.set(Calendar.HOUR_OF_DAY, hourOfDay);

				calendar.set(Calendar.MINUTE, minute);

				txtDatePicker.setText((hourOfDay < 10 ? "0" + hourOfDay : hourOfDay) + ":" + (minute < 10 ? "0" + minute : minute) + ":00");

			}

		}, calendar.get(Calendar.HOUR_OF_DAY), calendar.get(Calendar.MINUTE), true).show();

	}

@Override

private void initView() {
// 日期控件对象
DatePicker date = (DatePicker) findViewById(R.id.main_dp);
// 获得日历对象
Calendar c = Calendar.getInstance();
// 获取当前年份

// 时间显示的文本对象

// 为日期设置监听事件

//显示日期的方法

}

//显示时间的方法
