如何开发/修改屏幕锁

系统屏幕锁的源码在 在framework里面的phone/com/android/internal/policy/impl下面 http://gitorious.org/0xdroid/fra ... nternal/policy/impl这里可以看到源码 LockPatternKeyguardView它负责用来创建LockScreen和UnLockScreen和锁屏的模式（图案、Sim锁之类的） KeyguardViewMediator就是负责控制锁屏和键盘保护功能 --------------------------------------------------------------------- 下面的代码可以用来点亮屏幕 PowerManager pm = (PowerManager)getSystemService(POWER_SERVICE); mWakelock = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP |PowerManager.SCREEN_DIM_WAKE_LOCK, "SimpleTimer"); mWakelock.acquire(); ....... mWakelock.release(); 下面的代码用来屏幕解锁 KeyguardManager keyguardManager = (KeyguardManager)getSystemService(KEYGUARD_SERVICE); KeyguardLock keyguardLock = keyguardManager.newKeyguardLock("");  keyguardLock.disableKeyguard();  使用这两段代码，需要在AndroidManifest文件中加入 <uses-permission android:name="android.permission.DISABLE_KEYGUARD"></uses-permission> <uses-permission android:name="android.permission.WAKE_LOCK"></uses-permission> --------------------------------------------------------------------- 修改framework/base/policy下面的代码，phonewindow.java和lockscreen.java。 ---------------------------------------------------------------------
