android 滑动锁屏状态下如何禁止下拉状态栏？

滑动锁屏状态下状态栏可以下拉是google 4.0 默认的设计。如果要禁止此功能，请修改KeyguardViewMediator.java的adjustStatusBarLocked()方法，将

if (isSecure() || !ENABLE_INSECURE_STATUS_BAR_EXPAND) {

 // showing secure lockscreen; disable expanding.

 flags |= StatusBarManager.DISABLE_EXPAND;

 }

修改为：

if (isSecure() || ENABLE_INSECURE_STATUS_BAR_EXPAND) {

 // showing secure lockscreen; disable expanding.

 flags |= StatusBarManager.DISABLE_EXPAND;

 }
