【核心代码】
前端代码：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
	android:orientation="vertical" android:layout_width="fill_parent"
	android:layout_height="fill_parent">
	
	<DatePicker android:id="@ id/date" android:layout_width="wrap_content"
		android:layout_height="wrap_content" />
	<TimePicker android:id="@ id/time" android:layout_width="wrap_content"
		android:layout_height="wrap_content" />
	<EditText android:id="@ id/text1" android:layout_width="fill_parent"
		android:layout_height="wrap_content" />
</LinearLayout>

后端代码：

package com.test;

import android.app.Activity;
import android.os.Bundle;
import android.widget.DatePicker;
import android.widget.TimePicker;
import android.widget.DatePicker.OnDateChangedListener;
import android.widget.TimePicker.OnTimeChangedListener;

public class MainActivity extends Activity implements OnDateChangedListener,
		OnTimeChangedListener {

	android.widget.EditText text;
	android.widget.DatePicker date;
	android.widget.TimePicker time;

	public void onCreate(Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		setContentView(R.layout.main);
		date = (android.widget.DatePicker) this.findViewById(R.id.date);
		date.init(2009, 10, 10, this);
		time = (android.widget.TimePicker) this.findViewById(R.id.time);
		time.setIs24HourView(true);//**
		time.setOnTimeChangedListener(this);//**
		text = (android.widget.EditText) this.findViewById(R.id.text1);
		updateTime();

	}

	public void updateTime() {
		java.util.Calendar cal = java.util.Calendar.getInstance();
		cal.set(date.getYear(), date.getMonth(), date.getDayOfMonth(), time
				.getCurrentHour(), time.getCurrentMinute());
		java.util.Date date = cal.getTime();
		java.text.SimpleDateFormat dateFormat = new java.text.SimpleDateFormat(
				"yyyy-MM-dd hh:mm");
		text.setText(dateFormat.format(date));
	}

	public void onDateChanged(DatePicker view, int year, int monthOfYear,
			int dayOfMonth) {
		updateTime();
	}

	public void onTimeChanged(TimePicker view, int hourOfDay, int minute) {
		updateTime();
	}
}
