从单个对话框片段获取日期和时间选择器值并将其设置在 EditText 中

我正在开发一个用户可以设置日期和时间的应用程序。我想在单个对话框片段中设置日期和时间并将其设置为编辑文本。是否可以在 1 个对话框片段中使用日期和时间选择器？如果是的话，你会怎么做？ 目前我正在从对话框片段中获取时间，然后将其设置为EditText.

我的代码是

LaterTextView=(TextView)findViewById(R.id.PickUp_later_TextView);



       LaterTextView.setOnClickListener(new View.OnClickListener() {

            @SuppressWarnings("deprecation")
            public void onClick(View v) {
                showDialog(TIME_DIALOG_ID);

                }
        });




}


protected Dialog onCreateDialog(int id) {
    switch (id) {
    case TIME_DIALOG_ID:

        // set time picker as current time
        return new TimePickerDialog(this, timePickerListener, hour, minute,
                false);

    }
    return null;
}

private TimePickerDialog.OnTimeSetListener timePickerListener = new TimePickerDialog.OnTimeSetListener() {
    public void onTimeSet(TimePicker view, int selectedHour,
            int selectedMinute) {
        hour = selectedHour;
        minute = selectedMinute;

        // set current time into TextView
        setDate_time_EditTExt.setText(new StringBuilder().append(pad(hour))
                .append(":").append(pad(minute)));



    }
};
private static String pad(int c) {
    if (c >= 10)
        return String.valueOf(c);
    else
        return "0" + String.valueOf(c);
}

我想从同一个对话框片段设置日期和时间。

日期选择器 and 时间选择器 both 在单个对话框中。检查这个代码。
