Comment 0. There is a common pattern I use in all of my Android RecyclerView adapters to listen for click events on each item.
I created an interface that is similar to the normal click listener, except it also has the position as a parameter. With this interface, I can set up a view holder class as a click listener, and pass in an instance of my interface. Then I set the view itself as a click listener and call my interface with the appropriate position.
In your case you may not want to set the entire view as a click listener, maybe you have a button inside your layout. You can set it on that instead if you want, or add multiple listeners if you have multiple buttons for example.
This is just a simple example to demonstrate how it works. I pass in my interface to the adapter so it can pass it to the view holder. I create this listener when the adapter is instantiated. I am simply toasting the position that was tapped on, but you could do anything with the data at this point.
For example, you may have a list of notes, and tapping on one gives you its position in the list. With that, you can get the data object from the list and display the details of that note to the user. See the original article here. Over a million developers have joined DZone. Let's be friends:.

GestureDetector; import android. MotionEvent; import android. Context. RecyclerView. GestureDetector. MotionEvent. Context ; import android. RecyclerView ; import android. GestureDetector ; import android. MotionEvent ; import android.An OnItemTouchListener allows the application to intercept touch events in progress at the view hierarchy level of the RecyclerView before those touch events are considered for RecyclerView's own scrolling behavior.
This can be useful for applications that wish to implement various forms of gestural manipulation of item views within the RecyclerView. OnItemTouchListeners may intercept a touch interaction already in progress even if the RecyclerView is already handling that gesture stream itself for the purposes of scrolling.
Process a touch event as part of a gesture that was claimed by returning true from a previous call to onInterceptTouchEvent RecyclerView, MotionEvent.
The onInterceptTouchEvent methods of each attached OnItemTouchListener will be run in the order in which each listener was added, before any other touch processing by the RecyclerView itself or child views occurs.
