锁屏界面问题总结

一：锁屏界面时钟字体大小修改

frameworks/base/packages/Keyguard/res/values/dimens.xml

<dimen name="widget_big_font_size">80dp</dimen>

二：锁屏界面时钟竖直方向位置调整

frameworks\base\packages\SystemUI\res\values\dimens.xml

<fraction name="keyguard_clock_y_fraction_max">22.5%</fraction>

<fraction name="keyguard_clock_y_fraction_min">22.5%</fraction>

时钟水平方向的修改

packages\Keyguard\res_transsion\layout-v24\keyguard_status_view.xml

<LinearLayout

android:id="@+id/keyguard_clock_container"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_gravity="start|top"

android:orientation="vertical"

android:layout_marginLeft="16dp">

三：锁屏界面时钟的日期格式修改为首字母大写

frameworks/base/packages/Keyguard/res/layout/keyguard_status_area.xml

style="@style/widget_label"

- android:textAllCaps="true"

android:letterSpacing="0.15"

四：日期的字体大小问题

frameworks/base/packages/Keyguard/res/values/dimens.xml

- <dimen name="widget_label_font_size">14sp</dimen>

+ <dimen name="widget_label_font_size">16sp</dimen>

五：日期的格式修改流程

frameworks/base/packages/Keyguard/src/com/android/keyguard/KeyguardStatusView.java

final String dateViewSkel = res.getString(hasAlarm

? R.string.abbrev_wday_month_day_no_year_alarm

: R.string.abbrev_wday_month_day_no_year);

<string name="abbrev_wday_month_day_no_year">EEEEMMMMd</string>

<string name="abbrev_wday_month_day_no_year">EEEMMMd</string>

四个E、M为全写，三个E、M为简写，详情看下面这个接口说明就行了

dateView = DateFormat.getBestDateTimePattern(locale, dateViewSkel);

mDateView.setFormat24Hour(Patterns.dateView);

mDateView.setFormat12Hour(Patterns.dateView);

六：notification模板类

SystemUI\src\com\android\systemui\statusbar\NotificationBackgroundView.java

Y:\tianyajun\android7.0\frameworks\base\packages\SystemUI\src\com\android\systemui\statusbar\stack\NotificationStackScrollLayout.java
