android--日期時間控件

一、先看看實現的效果:

點擊日期2015-03-24會彈出選擇日期的對話框

點擊時間，則彈出時間的對話框

二、代碼如下：

1.xml文件

package com.example.time;

import java.sql.Date;
import java.text.DateFormat;
import java.text.SimpleDateFormat;
import java.util.Calendar;
import java.util.Locale;

import android.os.Bundle;
import android.app.Activity;
import android.app.DatePickerDialog;
import android.app.TimePickerDialog;
import android.util.Log;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.DatePicker;
import android.widget.TextView;
import android.widget.TimePicker;

public class MainActivity extends Activity {

	private final static String TAG=TimeDate;
	   //獲取日期格式器對象
    DateFormat fmtDate = new java.text.SimpleDateFormat(yyyy-MM-dd);
    
    DateFormat fmtTime = new java.text.SimpleDateFormat(HH:mm:ss);
    
    //定義一個TextView控件對象
    TextView txtDate = null;
    TextView txtTime = null;
    //獲取一個日歷對象
    Calendar dateAndTime = Calendar.getInstance(Locale.CHINA);
    
    
    //當點擊DatePickerDialog控件的設置按鈕時，調用該方法
    DatePickerDialog.OnDateSetListener d = new DatePickerDialog.OnDateSetListener()
    {
        @Override
        public void onDateSet(DatePicker view, int year, int monthOfYear,
                int dayOfMonth) {
            //修改日歷控件的年，月，日
            //這裡的year,monthOfYear,dayOfMonth的值與DatePickerDialog控件設置的最新值一致
            dateAndTime.set(Calendar.YEAR, year);
