参考以下代码
 解锁、唤醒屏幕用到KeyguardManager，KeyguardLock，PowerManager，PowerManager.WakeLock



所需权限：

<uses-permission android：name="android.permission.WAKE_LOCK" />



<uses-permission android：name="android.permission.DISABLE_KEYGUARD" />



//锁屏、唤醒相关

private KeyguardManager  km;

private KeyguardLock kl;

private PowerManager pm;

private PowerManager.WakeLock wl;







private void wakeAndUnlock(boolean b)

{

       if(b)

       {

              //获取电源管理器对象

              pm=(PowerManager) getSystemService(Context.POWER_SERVICE);



              //获取PowerManager.WakeLock对象，后面的参数|表示同时传入两个值，最后的是调试用的Tag

              wl = pm.newWakeLock(PowerManager.ACQUIRE_CAUSES_WAKEUP | PowerManager.SCREEN_BRIGHT_WAKE_LOCK, "bright");



              //点亮屏幕

              wl.acquire();



              //得到键盘锁管理器对象

              km= (KeyguardManager)getSystemService(Context.KEYGUARD_SERVICE);

              kl = km.newKeyguardLock("unLock");



              //解锁

              kl.disableKeyguard();

       }

       else

       {

              //锁屏

              kl.reenableKeyguard();



              //释放wakeLock，关灯

              wl.release();

       }
