最近一直在头疼怎样在修改Settings-----Date&Time---Choose data format 后通知更新桌面时钟 AppWidget的日期格式跟着Setting的改变而改变...

想实现的效果就是如下：

原先日期格式是这样，

当点击修改Settings-----Date&Time---Choose data format，

想动态实现，就有点不知道怎么解决了，

这个布局其实是一个TextClock 

          <TextClock
            android:id="@+id/date"
            style="@style/label"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:format12Hour="@string/abbrev_wday_month_day_no_year"
            android:format24Hour="@string/abbrev_wday_month_day_no_year"
            android:gravity="center"
            android:textColor="@color/clock_white" />

<resources xmlns:xliff="urn:oasis:names:tc:xliff:document:1.2">
    <!-- 字符串匹配的锁定屏幕显示日期的格式. MM/dd/yyy-->
    <string name="abbrev_wday_month_day_no_year">dd-MM-yyyy</string>
    <!-- Format for describing the date, for accessibility. -->
    <string name="full_wday_month_day_no_year">EEEE, MMMM d</string>
    <!-- Default clock style. -->
    <string name="default_clock_style">digital</string>
</resources>

比如修改为：<string name="abbrev_wday_month_day_no_year">EE-d-MMM-yyyy</string>

这个有点不靠谱，或者修改为如下格式

日期格式的值的方法有如下：

  <string-array name="date_format_values" translatable="false">
        <!-- The blank item means to use whatever the locale calls for. -->
        <item></item>
        <item>MM-dd-yyyy</item>
        <item>dd-MM-yyyy</item>
        <item>yyyy-MM-dd</item>
        <item>EE-MMM-d-yyyy</item>
        <item>EE-d-MMM-yyyy</item>
        <item>yyyy-MMM-d-EE</item>
    </string-array>

网上收到的一些方法有如下，自己是小菜鸟一枚，看了好久还是没有解决掉这个问题，希望有大神能够帮助一下...
