大家好，又见面了，我是你们的朋友全栈君。

代码语言：javascript复制
在SystemUI里的Android.mk中

LOCAL_STATIC_JAVA_LIBRARIES := Keyguard

LOCAL_STATIC_JAVA_LIBRARIES = com.mediatek.systemui.ext

LOCAL_JAVA_LIBRARIES := telephony-common

LOCAL_JAVA_LIBRARIES = mediatek-framework

LOCAL_JAVA_LIBRARIES = ims-common

LOCAL_PACKAGE_NAME := SystemUI LOCAL_CERTIFICATE := platform

代码语言：javascript复制
LOCAL_PRIVILEGED_MODULE := true
LOCAL_PROGUARD_FLAG_FILES := proguard.flags
LOCAL_RESOURCE_DIR :=

frameworks/base/packages/Keyguard/res

frameworks/base/packages/Keyguard/res_ext

$(LOCAL_PATH)/res

$(LOCAL_PATH)/res_ext

发现其中的资源文件来自Keyguard。那么我们要在Keyguard里做修改，编译SystemUI。

1.frameworks/base/packages/Keyguard/res/layout/keyguard_status_view.xml这是锁屏上的时钟界面

2. keyguard_status_area.xml日期

代码语言：javascript复制
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:androidprv="http://schemas.android.com/apk/res-auto"
android:layout_width="match_parent"
android:layout_height="wrap_content"

android:gravity="left">
<TextClock android:id="@ id/date_view"

android:letterSpacing="0.15"
android:gravity="left"

<TextView android:id="@ id/alarm_status"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:drawablePadding="6dp"
android:drawableStart="@drawable/ic_access_alarms_big"

android:textAllCaps="true"
style="@style/widget_label"
android:layout_marginStart="6dp"
android:gravity="center"
android:visibility="gone"
/>
</LinearLayout>

第一个xml文件主要修改的是layout_gravity属性；第二个xml文件修改的是android:gravity的属性
