Introduction

RecyclerView is a more advanced version of List View with improved performance and additional features.

Parameters

ParameterDetail
AdapterA subclass of RecyclerView.Adapter responsible for providing views that represent items in a data set
PositionThe position of a data item within an Adapter
IndexThe index of an attached child view as used in a call to getChildAt(int). Contrast with Position
BindingThe process of preparing a child view to display data corresponding to a position within the adapter
Recycle (view)A view previously used to display data for a specific adapter position may be placed in a cache for later reuse to display the same type of data again later. This can drastically improve performance by skipping initial layout inflation or construction
Scrap (view)A child view that has entered into a temporarily detached state during layout. Scrap views may be reused without becoming fully detached from the parent RecyclerView, either unmodified if no rebinding is required or modified by the adapter if the view was considered dirty
Dirty (view)A child view that must be rebound by the adapter before being displayed

Remarks

The RecyclerView is a flexible view for providing a limited window into a large data set.

Before using the RecyclerView you have to add the support library dependency in the build.gradle file:

dependencies {
    // Match the version of your support library dependency
    compile 'com.android.support:recyclerview-v7:25.3.1'
}

You can find latest version number of recyclerview from official site.
