You can put both Date Picker and Time Picker in a layout XML: Referring this date_time_picker.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="match_parent"
android:padding="8dp"
android:layout_height="match_parent">

<DatePicker
android:id="@+id/date_picker"
android:layout_width="match_parent"
android:calendarViewShown="true"
android:spinnersShown="false"
android:layout_weight="4"
android:layout_height="0dp" />

<TimePicker
android:id="@+id/time_picker"
android:layout_weight="4"
android:layout_width="match_parent"
android:layout_height="0dp" />

<Button
android:id="@+id/date_time_set"
android:layout_weight="1"
android:layout_width="match_parent"
android:text="Set"
android:layout_height="0dp" />

</LinearLayout>

The code

    final View dialogView = View.inflate(activity, R.layout.date_time_picker, null);
final AlertDialog alertDialog = new AlertDialog.Builder(activity).create();

dialogView.findViewById(R.id.date_time_set).setOnClickListener(new View.OnClickListener() {
    @Override
    public void onClick(View view) {

         DatePicker datePicker = (DatePicker) dialogView.findViewById(R.id.date_picker);
         TimePicker timePicker = (TimePicker) dialogView.findViewById(R.id.time_picker);

         Calendar calendar = new GregorianCalendar(datePicker.getYear(),
    datePicker.getMonth(),
    datePicker.getDayOfMonth(),
     timePicker.getCurrentHour(),
                            timePicker.getCurrentMinute());

         time = calendar.getTimeInMillis();
         alertDialog.dismiss();
    }});
    alertDialog.setView(dialogView);
    alertDialog.show();
