Android调用点亮屏幕解锁

//获取电源管理器对象
PowerManager 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
PowerManager.WakeLock 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
KeyguardManager km = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
//判断是否有密码锁屏
if (!km.isKeyguardSecure()) {
    KeyguardManager.KeyguardLock kl = km.newKeyguardLock("unLock");
    //解锁
    kl.disableKeyguard();
}
