You can call TimePicker after DatePicker set Date. Like this..

您可以在DatePicker设置日期之后调用TimePicker。像这样的. .

    String date_time = "";
    int mYear;
    int mMonth;
    int mDay;

    int mHour;
    int mMinute;

    et_show_date_time = (EditText) findViewById(R.id.et_show_date_time);
    btn_set_date_time = (Button) findViewById(R.id.btn_set_date_time);

    btn_set_date_time.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            datePicker();

        }
    });

Date Picker:

日期选择器:

    private void datePicker(){

    // Get Current Date
    final Calendar c = Calendar.getInstance();
    mYear = c.get(Calendar.YEAR);
    mMOnth= c.get(Calendar.MONTH);
    mDay = c.get(Calendar.DAY_OF_MONTH);

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

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

                    date_time = dayOfMonth + "-" + (monthOfYear + 1) + "-" + year;
                   //*************Call Time Picker Here ********************
                   tiemPicker();
                }
            }, mYear, mMonth, mDay);
       datePickerDialog.show();
    }

Time Picker

时间选择器

 private void tiemPicker(){
    // Get Current Time
    final Calendar c = Calendar.getInstance();
    mHour = c.get(Calendar.HOUR_OF_DAY);
    mMinute = c.get(Calendar.MINUTE);

    // Launch Time Picker Dialog
    TimePickerDialog timePickerDialog = new TimePickerDialog(this,
            new TimePickerDialog.OnTimeSetListener() {

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

                    mHour = hourOfDay;
                    mMinute = minute;

                    et_show_date_time.setText(date_time+" "+hourOfDay + ":" + minute);
                }
            }, mHour, mMinute, false);
    timePickerDialog.show();
}

I do it for you.......it will work 100%

If you need to select the time right after the date selection you can simply show TimePickerDialog automatically after date is selected. This is the easiest way.

如果您需要在日期选择之后选择时间，您可以在日期选择之后自动显示TimePickerDialog。这是最简单的方法。

While you have listener that is fired when date is selected with selected date, you can simply pass that selected date to TimePickerDialog and with a few customization in mdtp_time_picker_dialog.xml you can add a TextView to show the selected text.

当您有一个监听器在选择日期时被触发，您可以简单地将选择的日期传递给TimePickerDialog并在mdtp_time_picker_dialog中进行一些定制。您可以添加一个TextView来显示所选的文本。

Another option is merging mdtp_time_picker_dialog.xml and mdtp_date_picker_dialog.xml that are root layouts for date picker dialog and time picker dialog. You can set time picker part visibility as GONE and switch the visibility when you want to switch pickers.

另一个选项是合并mdtp_time_picker_dialog。xml和mdtp_date_picker_dialog。xml是日期选择器对话框和时间选择器对话框的根布局。您可以设置时间选择器部件的可见性，并在您想要切换选择器时切换可见性。

The second solution is more difficult to implement because in addition to layouts, you have to merge all controls and listeners.

第二个解决方案更难实现，因为除了布局之外，还必须合并所有控件和侦听器。

If you want the user to see both of the pickers, I think you actually need to design a new view yourself. That library layouts is not suitable for this.

如果您想让用户看到这两个选择器，我认为您实际上需要自己设计一个新的视图。库布局不适合这种情况。

        public void onDateSet(DatePicker view, int year, int month, int dayOfMonth) {
            calendar.set(Calendar.YEAR, year);
            calendar.set(Calendar.MONTH, month);

                true);
        timePickerDialog.show();
    }

    public void release() {
        closeDialogs();
        dateResultCallback = null;
    }

}

Dialogs calls via method showDialog(...), possible to release object when it not need anymore (in onDestroy() in activity f.e). And again - thanks Enamul Haque for idea.

对话框通过方法showDialog(…)调用，当对象不再需要时(在活动f.e的onDestroy()中)释放对象。再次谢谢你的想法。
