利用Android应用框架提供的DatePicker(日期选择器)和TimePicker(时间选择器)，实现日期时间选择器。

Dialog的Content布局文件(date_time_dialog.xml)：

android:layout_width="fill_parent"

android:layout_height="fill_parent"

android:orientation="vertical"

android:padding="10dip" >

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:singleLine="true"

android:text="请选择日期"

android:textColor="#FFFFFF"

android:textSize="16sp" />

android:id="@+id/date_picker"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="5dip" />

android:layout_width="fill_parent"

android:layout_height="wrap_content"

android:layout_marginTop="10dip"

android:singleLine="true"

android:text="请选择时间"

android:textColor="#FFFFFF"

android:textSize="16sp" />

android:id="@+id/time_picker"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_marginTop="5dip" />

代码中的实现：

package com.easipass.test;

import java.util.Calendar;

import android.app.Activity;

import android.app.AlertDialog;

import android.app.Dialog;

import android.content.DialogInterface;

import android.os.Bundle;

import android.text.InputType;

import android.view.MotionEvent;

import android.view.View;

import android.widget.DatePicker;

import android.widget.EditText;

import android.widget.TimePicker;
