android - 创建函数以使用 DatePickerDialog 和 TimePickerDiaglog 来捕获用户输入的日期时间

Question

我正在尝试编写一个函数来捕获用户输入的Date 和time 并将其存储在一个字符串值中。我成功创建了 DatePickerDialog，但创建了 TimePickerDialog。我收到错误“无法解析构造函数...”(尽管使用与 DatePickerDialog 相同的代码。非常感谢任何帮助。谢谢

这是我的函数代码

public void showDatePicker(View view) {
        final Calendar c = Calendar.getInstance();
        int mYear = c.get(Calendar.YEAR);
        int mMonth = c.get(Calendar.MONTH);
        int mDay = c.get(Calendar.DAY_OF_MONTH);

        int mHour = c.get(Calendar.HOUR);
        int mMinute = c.get(Calendar.MINUTE);

        final TextView selectDate = (TextView) findViewById(R.id.selectDate);


        DatePickerDialog datePickerDialog = new DatePickerDialog(DateTimePicker.this, new DatePickerDialog.OnDateSetListener() {
            @Override
            public void onDateSet(DatePicker view, int year, int monthOfYear, int dayOfMonth) {
                // dd.MM.yyyy
                selectDate.setText(dayOfMonth + "." + (monthOfYear + 1) + "." + year);
            }
        }, mYear, mMonth, mDay);
        datePickerDialog.show();

        TimePickerDialog timePickerDialog = new TimePickerDialog(DateTimePicker.this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(android.widget.TimePicker view, int hourOfDay, int minute) {
                selectDate.append(hourOfDay + "." +minute);
            }
        },mHour,mMinute);
        timePickerDialog.show();
}

还有一个问题是如何将字符串 $selectDate 转换为 Timestamp 并存储到远程 MySQL 数据库？

根据 Timepicker dialog documentation :

公共(public)构造函数

TimePickerDialog(Context context, TimePickerDialog.OnTimeSetListener listener, int hourOfDay, int minute, boolean is24HourView)

创建一个新的时间选择器对话框。

TimePickerDialog(Context context, int themeResId, TimePickerDialog.OnTimeSetListener listener, int hourOfDay, int minute, boolean is24HourView)

创建一个具有指定主题的新时间选择器对话框。

所以，请按照此操作，您需要另一个 bool 类型的参数来创建 TimePickerDialog 对象。

例如，

TimePickerDialog timePickerDialog = new TimePickerDialog(DateTimePicker.this, new TimePickerDialog.OnTimeSetListener() {
            @Override
            public void onTimeSet(android.widget.TimePicker view, int hourOfDay, int minute) {
                selectDate.append(hourOfDay + "." +minute);
            }
        },mHour,mMinute,false);
