当从 Android 的锁定屏幕单击通知操作时，如何以编程方式解锁屏幕？

Question

When the screen is locked and the user chooses a positive response to a notification action from the lock screen, how do I add code to prompt a screen unlock? Here is the code to my current positive notification action that i have added to the notification builder, when this action is chosen I have added an intent in the class that extends the IntentService to navigate to an activity in the app:

private static Action yesLetsGo(Context context) {

        Intent intent = new Intent(context, NotificationIntentService.class);
        intent.setAction(NotificationTasks.ACTION_YES_LETS_GO_NOTIFICATION);

        PendingIntent yesLetsGo = PendingIntent.getService(
                context,
                ACTION_YES_LETS_GO_PENDING_INTENT_ID,
                intent,
                PendingIntent.FLAG_UPDATE_CURRENT);

        Action yesLetsGoAction = new Action
                (R.drawable.ic_launcher_background,
                        "Yes Lets Go",
                        yesLetsGo);

        Log.i("Notification Utils","yesLetsGo method called");

        return yesLetsGoAction;

    }

For enabling or disabling lock screen in Android, we need to get the instance of KeyguardManager

KeyguardManager keyguardManager = (KeyguardManager)getSystemService(Activity.KEYGUARD_SERVICE);  
KeyguardLock lock = keyguardManager.newKeyguardLock(KEYGUARD_SERVICE);  

and for disabling the lock use,

lock.disableKeyguard();

And of course we need the permission in the Manifest

android.permission.DISABLE_KEYGUARD
