powermanager pm = (powermanager) getsystemservice(context.power_service);
mwakelock = pm.newwakelock(powermanager.full_wake_lock | powermanager.acquire_causes_wakeup, lock_tag);
mwakelock.acquire();

//释放屏幕常亮锁
if(null != mwakelock) {
    mwakelock.release();
}

2、android屏幕解锁和锁定

//屏幕解锁
keyguardmanager keyguardmanager = (keyguardmanager)getsystemservice(keyguard_service);
keyguardlock keyguardlock = keyguardmanager.newkeyguardlock(lock_tag);
keyguardlock.disablekeyguard();
//屏幕锁定
keyguardlock.reenablekeyguard();

3、相关权限

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