Android Nougat Reply Notification Demo

Starting in Android 7.0 (API level 24) You have a lot of control, and you’re getting even more. Google has also done some cleanup to make all of those alerts look more refined and add in some color in the right places to make it easier to quickly see the most important information.

From the lock screen, you’ll notice the subtle aesthetic differences, but just as before you can swipe the away or tug down slightly to launch the Quick Reply. To type, you’ll need to unlock the device with the fingerprint reader, PIN, pass-code, or pattern.

With the new notification type introduce in Android 7.0 (Nougat) users can respond directly to text messages or update task lists from within the notification dialog. On a handheld, the inline reply action appears as an additional button displayed in the notification. A user replies via keyboard, the system attaches the text response to the intent you had specified for the notification action and sends the intent to your handheld app.


Lets  Get Started with Tutorial

  • Create an instance of RemoteInput.Builder that you can add to your notification action.

  •  Attach the RemoteInput


  • Apply the action to a notification


Above codes need sending notification.

Read text written on REPLY.

  • Query the bundle using the result key


  • Give another notification using the same notification ID that you provided for the previous notification. The progress indicator disappears from the notification interface to inform users of a successful reply.

Control Smooth Scroll over Recycler View

In this post I will show you how can you achieve smooth scroll over RecyclerView

The key to a smoothly scrolling RecyclerView is to keep the application’s main thread (the UI thread) free from heavy processing. Recycler view is a flexible view for providing a limited window into a large data set.

Making Listview smooth there are many examples but none for the RecyclerView. Sometime its happen that user fling the screen so fast that RecyclerView looks shaky. It leave bad impression on the user.

For smooth scroll we need to control fling of the user. I have made custom class that extends RecyclerView. This can be achieve in just 3 steps.

Step 1 :

Create CustomRecyclerView Class. Below class is particular for Vertical RecyclerView.

For Horizontal RecyclerView just change fling method.

Step 2:

Because of we are using custom class for the RecyclerView we need to use class name with package name in the XML layout as well.


For example your create CustomRecyclerView under com.sid.views then in XML it will be com.sid.views.CustomRecyclerView

Step 3:

And the last step for reading custom class in the java. We need to use like that. This is TypeCasting to our Custom class.


You can get complete class from GitHub. For more information regarding smooth scroll go to this Question.
