[android] 解决DatePickerDialog和TimePickerDialog控件取消按钮问题
一. 问题提出
在Android程序中，我们通常需要使用DatePicker来设置日期，TimePicker来设置时间。其基本步骤是：
1.先定义DatePicker和TimePicker布局
2.然后通过Calendar类获得系统时间
3.接着通过init方法将日期传递给DatePicker初始化日期控件
4.在响应点击事件中可以通过DatePicker的getYear()、getDayOfMonth()、getMonth()函数获取具体日期
同时可以在OnDateChangedListener事件中监听日期变化，设置时间函数方法同理。但是使用DatePickerDialog或TimePickerDialog控件时会遇到的一个问题，它就是android版本4.0后没有取消(Cancel)按钮，同时点击界面任何部分都能获取日期或时间，据说它是版本存在的BUG。对比图如下所示：
但是我们期待的效果如下图所示：
我采取的解决方法是通过自定义XML布局，经过DatePicker和TimePicker控件实现，同时在AlertDialog中设置取消按钮和确定按钮，通过函数setNegativeButton()和setPositiveButton()实现。
二. 简单实现日期和时间控件
简单实现方法非常简单，不需要设置日期或时间的XML布局，直接通过new DatePickerDialog或TimePickerDialog即可实现。代码如下：
//点击日期按钮布局 设置日期
layoutDate.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
new DatePickerDialog(MainActivity.this, new DatePickerDialog.OnDateSetListener() {
public void onDateSet(DatePicker view, int year, int month, int day) {
// TODO Auto-generated method stub
//更新EditText控件日期 小于10加0
dateEdit.setText(new StringBuilder().append(mYear).append(-)
.append((mMonth + 1) & 10 ? 0 + (mMonth + 1) : (mMonth + 1))
.append(-)
.append((mDay & 10) ? 0 + mDay : mDay) );
}, calendar.get(Calendar.YEAR), calendar.get(Calendar.MONTH),
calendar.get(Calendar.DAY_OF_MONTH) ).show();
其中mYear、mMonth、mDay是定义变量，同时dateEdit是一个EditText控件用于显示具体日期，当数字小于10时前补0，如。下面是设置时间，显示效果和第三部分的效果相同。
//点击时间按钮布局 设置时间
layoutTime.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
new TimePickerDialog(MainActivity.this,
new TimePickerDialog.OnTimeSetListener() {
public void onTimeSet(TimePicker view, int hour, int minute) {
// TODO Auto-generated method stub
//更新EditText控件时间 小于10加0
timeEdit.setText(new StringBuilder()
.append(mHour & 10 ? 0 + mHour : mHour).append(:)
.append(mMinute & 10 ? 0 + mMinute : mMinute).append(:00) );
}, calendar.get(Calendar.HOUR_OF_DAY),
calendar.get(Calendar.MINUTE), true).show();
三. 自定义布局实现
下面是自定义布局实现，而且我自认为该界面布局非常好看，这也是我&随手拍&项目自己最后总结出来的一个比较欣赏的界面吧！希望你也喜欢，效果如下：
如图所示，界面中日期、时间EditText不可编辑，需要通过点击底部布局来设置。同时备注信息的EditText通过自定义背景实现，设置日期、时间中有取消按钮。
1.项目结构如下图所示
2.activity_main.xml布局文件
3.date_dialog.xml文件：日期控件布局
4.time_dialog.xml文件：时间控件布局
5.drawable-hdpi中editview_shape.xml文件 实现自定义EditText控件格式
6.MainActivity.java
public class MainActivity extends Activity {
//自定义变量
private EditText titleE
private EditText dateE
private EditText timeE
private EditText contentE
//底部四个布局按钮
private LinearLayout layoutD
private LinearLayout layoutT
private LinearLayout layoutC
private LinearLayout layoutS
//定义显示时间控件
private C //通过Calendar获取系统时间
private int mY
private int mM
private int mD
private int mH
private int mM

最后希望文章对大家有所帮助！如果你知道我这篇文章想要阐述的内容是什么？为什么要写这篇文章？或许它会对你有所帮助，一方面是布局可能对你有启发；另一方面就是刚好遇到那个问题的同学。
在点击&保存&按钮时，也可把数据存储至数据库中调用MySQLiteOpenHelper，这里就不再介绍。写着写着就到了凌晨5点了，程序猿生活还是要改下啊~自己保重自己的身体吧！期待改正自己的作息，难难难~

A JavaScript component for choosing date ranges.
Designed to work with the Bootstrap CSS framework.
Originally built for reporting at ,
the Date Range Picker can be attached to any webpage element to pop up two calendars
for selecting dates, times, or from predefined ranges like "Last 30 Days".
Date Range Picker relies on ,
Include the required scripts and stylesheet in your page:
Then attach the picker to the element you want to trigger it:
You can customize Date Range Picker with , and
get notified when the user chooses new dates by providing a callback function.
Date Range Picker
The Date Range Picker is attached to a text input. It will use the current
value of the input to initialize, and update the input if new dates are chosen.
Date and Time
The Date Range Picker can also be used to select times. Hour, minute and (optional)
second dropdowns are added below the calendars. An option exists to set the increment
count of the minutes dropdown to e.g. offer only 15-minute or 30-minute increments.
Single Date Picker
The Date Range Picker can be turned into a single date picker widget with only
one calendar. In this example, dropdowns to select a month and year have also
been enabled at the top of the calendar to quickly jump to different months.
Predefined Ranges
This example shows the option to predefine date ranges that
the user can choose from a list.
Input Initially Empty
If you're using a date range as a filter, you may want to attach a picker to an
input but leave it empty by default. This example shows how to accomplish that
using the autoUpdateInput setting, and the apply and
cancel events.

Configuration
startDate (Date object, moment object or string) The start of the initially selected date range
endDate: (Date object, moment object or string) The end of the initially selected date range
minDate: (Date object, moment object or string) The earliest date a user may select
maxDate: (Date object, moment object or string) The latest date a user may select
dateLimit: (object) The maximum span between the selected start and end dates. Can have any property you can add to a moment object (i.e. days, months)
showDropdowns: (boolean) Show year and month select boxes above calendars to jump to a specific month and year
showWeekNumbers: (boolean) Show localized week numbers at the start of each week on the calendars
showWeekNumbers: (boolean) Show ISO week numbers at the start of each week on the calendars
timePicker: (boolean) Allow selection of dates with times, not just dates
timePickerIncrement: (number) Increment of the minutes selection list for times (i.e. 30 to allow only selection of times ending in 0 or 30)
timePicker24Hour: (boolean) Use 24-hour instead of 12-hour times, removing the AM/PM selection
timePickerSeconds: (boolean) Show seconds in the timePicker
ranges: (object) Set predefined date ranges the user can select from. Each key is the label for the range, and its value an array with two dates representing the bounds of the range
opens: (string: 'left'/'right'/'center') Whether the picker appears aligned to the left, to the right, or centered under the HTML element it's attached to
drops: (string: 'down' or 'up') Whether the picker appears below (default) or above the HTML element it's attached to
buttonClasses: (array) CSS class names that will be added to all buttons in the picker
applyClass: (string) CSS class string that will be added to the apply button
cancelClass: (string) CSS class string that will be added to the cancel button
locale: (object) Allows you to provide localized strings for buttons and labels, customize the date display format, and change the first day of week for the calendars
singleDatePicker: (boolean) Show only a single calendar to choose one date, instead of a range picke the start and end dates provided to your callback will be the same single date chosen
autoApply: (boolean) Hide the apply and cancel buttons, and automatically apply a new date range as soon as two dates or a predefined range is selected
linkedCalendars: (boolean) When enabled, the two calendars displayed will always be for two sequential months (i.e. January and February), and both will be advanced when clicking the left or right arrows above the calendars. When disabled, the two calendars can be individually advanced and display any month/year.
parentEl: (string) jQuery selector of the parent element that the date range picker will be added to, if not provided this will be 'body'
isInvalidDate: (function) A function that is passed each date in the two
calendars before they are displayed, and may return true or false to indicate whether
that date should be available for selection or not.
autoUpdateInput: (boolean) Indicates whether the date range picker should
automatically update the value of an &input& element it's attached to
at initialization and when the selected dates change.
alwaysShowCalendars: (boolean) Normally, if you use the ranges
option to specify pre-defined date ranges, calendars for choosing a custom date range are not shown until the user clicks "Custom Range". When this option is set to true, the calendars for choosing a custom date range are always shown instead.
You can programmatically update the startDate and endDate
in the picker using the setStartDate and setEndDate methods.
You can access the Date Range Picker object and its functions and properties through
data properties of the element you attached it to.
setStartDate(Date/moment/string): Sets the date range picker's currently selected start date to the provided date
setEndDate(Date/moment/string): Sets the date range picker's currently selected end date to the provided date
Example usage:
Several events are triggered on the element you attach the picker to, which you can listen for.
show.daterangepicker: Triggered when the picker is shown
hide.daterangepicker: Triggered when the picker is hidden
showCalendar.daterangepicker: Triggered when the calendar(s) are shown
hideCalendar.daterangepicker: Triggered when the calendar(s) are hidden
apply.daterangepicker: Triggered when the apply button is clicked,
or when a predefined range is clicked
cancel.daterangepicker: Triggered when the cancel button is clicked
Some applications need a "clear" instead of a "cancel" functionality, which can be achieved by changing the button label and watching for the cancel event:
While passing in a callback to the constructor is the easiest way to listen for changes in the selected date range, you can also do something every time the apply button is clicked even if the selection hasn't changed:
