之所以写这个东西，是因为在我们的设计中需要给 日期选择器加一个标题，一开始直接使用 原生的 DatePickerAlertDialog ，因为他继承自 AlertDialog ,所以就直接 调用了 setTitle 方法，然而，丑的那叫一塌糊涂啊。所以，最后只好自己简单包装一下。

内容简单，不做过多解释，直接上代码。

代码中调用：

/*** 展示时间选择器*/private void showTimePickerDialog(final int year, final int month, final int dayOfMonth) {Calendar calendar2 = Calendar.getInstance();int hour = calendar2.get(Calendar.HOUR_OF_DAY);int minute = calendar2.get(Calendar.MINUTE);CustomTimePickerAlertDialog timePickerAlertDialog = new CustomTimePickerAlertDialog(context, hour, minute);timePickerAlertDialog.setCancelable(false);timePickerAlertDialog.setTitle("请设置迟到判定时间——时：分");timePickerAlertDialog.setPositiveButton("确定", new CustomTimePickerAlertDialog.AntTimePickerDialogClickListener() {@Overridepublic void onClick(View view, int selectedHour, int selectedMinute) {LogUtils.e("最终设置的时间是：", selectedHour + "/" + selectedMinute);sendLateTimeToServer(year, month, dayOfMonth, selectedHour, selectedMinute);}});timePickerAlertDialog.setSkipButton("跳过", new CustomTimePickerAlertDialog.AntTimePickerDialogClickListener() {@Overridepublic void onClick(View view, int selectedHour, int selectedMinute) {sendLateTimeToServer(0, 0, 0, 0, 0);goToSignSituationAct();}});timePickerAlertDialog.setNegativeButton("取消", null);timePickerAlertDialog.show();}

3 总结：

以上内容就是完整代码，整体比较简单。

• DatePicker 设置 为 Spinner 模式时这里使用了style="@android:style/Widget.DatePicker"
• TimePicker 设置为 Spinner 模式时使用了 timePickerMode=spinner , 之所以不用 style ，是因为spinner 模式的 style="@android:style/Widget.TimePicker"被系统 私有了，无法调用，系统对外提供的都是 MaterialDesign 模式的Style

最初是想将 DatePicker 和 TimePicker 包装到同一个 AlertDialog 中，但是非常遗憾，TimePicker 和 DatePicker 底层用的是 NumberPicker ，宽度写死了，导致 将 TimePicker 和 DatePicker 横向放在同一个 AlertDialog 中时会导致超出宽度，部分内容无法展示。这种情况暂时没想好怎么解决，如果哪位大侠知道，烦请告知，谢谢!
