Android的：如何从MM / DD / YYYY改变的DatePicker查看日期格式DD / MM / YYYY？ [英] Android: How to change the DatePicker view date format from MM/dd/yyyy to dd/MM/yyyy?

问题描述

我一直在试图让一个回答这个问题相当长一段时间。我也有一个看看下面的链接：机器人 - 的DatePicker控件格式。 在我的手机/仿真器（V 2.3.3）都DatePicker的小部件和对话框不采取设置中指定的日期格式（设置 - >日期和放大器;时间 - >选择日期格式）。他们总是在格式为MM / DD / YYYY。该区域被设置为英语（英国）。

I have been trying to get an answer to this question for quite a while. I also had a look at the following link: Android - DatePicker Widget Format. On my phone/ emulator (v 2.3.3) both the DatePicker widget and the dialog do not take the date format specified in settings (Settings->Date&Time->Select date format). They are always in the format "MM/dd/yyyy". The locale is set to English UK.

我得到D / MM / YYYY当我读到的设置有：

I get "d/MM/yyyy" when I read the settings with:

Settings.System.getString（getContentResolver（），Settings.System.DATE_FORMAT）;

有没有人有关于如何更改日期格式在一个datepicker视图的想法？

Does anybody have an idea about how to change the date format in a DatePicker view?

推荐答案

要覆盖的DatePicker格式化最好的选择将覆盖它的构造函数之一有轻微的编辑到原来的code。您可以编辑的ViewGroup在$ C $下你，但我会认真考虑不这样做的方式。

To override the DatePicker format the best bet would be to override one of its constructors with a slight edit to the original code. You can edit the ViewGroup in code for you but I'd seriously consider not doing it that way.

1. 创建类LocalizedDatePicker
2. 覆盖<一href="http://developer.android.com/reference/android/widget/DatePicker.html#DatePicker%28android.content.Context,%20android.util.AttributeSet,%20int%29"相对=nofollow>公开的DatePicker（上下文的背景下，ATTRS的AttributeSet，INT defStyle） <一href="http://developer.android.com/reference/android/widget/DatePicker.html#DatePicker(android.content.Context" rel="nofollow">http://developer.android.com/reference/android/widget/DatePicker.html#DatePicker(android.content.Context, android.util.AttributeSet，INT）
3. 复制从<一的code href="https://android.googlesource.com/platform/frameworks/base/+/HEAD/core/java/android/widget/DatePicker.java"相对=nofollow>原来的DatePicker构造（您可能需要选择在一些测试不同的分支，我已经挂了头）
调用reorderSpinners
4. 在覆盖（）的方法来消除这一呼吁。
5. 替换行 inflater.inflate（R.layout.date_picker，这个，真）; 与 inflater.inflate（my.package.R。 layout.localized_date_picker，这个，真）;
6. 复制原date_picker.xml布局，以当地资源localized_date_picker.xml
7. 编辑所需的顺序文件，因为您正在编辑该请尊重其他地方的定位，并保持原有的副本在您的全球布局文件夹，并把localized_date_picker.xml在您所在地区指定的文件夹。由于系统的布局是月日年人在其他地方可能期望的顺序。

1. Create class LocalizedDatePicker
2. Override public DatePicker (Context context, AttributeSet attrs, int defStyle) http://developer.android.com/reference/android/widget/DatePicker.html#DatePicker(android.content.Context, android.util.AttributeSet, int)
3. Copy the code from the original DatePicker constructor (you may need to select a different branch after some testing, I have linked the head)
4. Override methods that call reorderSpinners() to remove that call.
5. Replace line inflater.inflate(R.layout.date_picker, this, true); with inflater.inflate(my.package.R.layout.localized_date_picker, this, true);
6. Copy the original date_picker.xml layout to your local resource localized_date_picker.xml
7. Edit the file for the desired order, since you're editing this please respect the localization of other places and keep a copy of the original in your global layout folder and put the localized_date_picker.xml in your region specific folder. Since the system's layout is Month Day Year people in other places may expect that order.
