我正在尝试更改 Settings.apk 中的默认值。
起初，我将“android:default value”（0=right，1=centered）添加到 status_bar_clock_style.xml，但没有成功。
<ListPreference android:entries="@array/clock_style_entries" android:title="@string/clock_title_enable" android:key="clock_style" android:dependency="status_bar_show_clock" android:entryValues="@array/clock_style_values" android:defaultValue="1" />
然后将 smali 转换为 java 并在那里进行更改也没有用，因为我无法再次编译代码。那会容易得多...
于是我在StatusBarClockStyle.smali的相关方法中试验改了序言。现在默认选择该值，但仍未实现。

有人能指出我正确的方向吗？或者告诉我如何以另一种方式实现这一目标？谢谢 =)
（编辑：我知道我可以在 status_bar.xml 中执行此操作，这通常是关于更改默认值。）
