Recyclerview Vs. Listview

RecyclerView vs. ListView

RecyclerView was created as a ListView improvement, so yes, you can create an attached list with ListView control, but using RecyclerView is easier as it:

  1. Reuses cells while scrolling up/down - this is possible with implementing View Holder in the ListView adapter, but it was an optional thing, while in the RecycleView it's the default way of writing adapter.

  2. Decouples list from its container - so you can put list items easily at run time in the different containers (linearLayout, gridLayout) with setting LayoutManager.

Example:

mRecyclerView = (RecyclerView) findViewById(R.id.my_recycler_view);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
//or
mRecyclerView.setLayoutManager(new GridLayoutManager(this, 2));

  1. Animates common list actions - Animations are decoupled and delegated to ItemAnimator.

There is more about RecyclerView, but I think these points are the main ones.

So, to conclude, RecyclerView is a more flexible control for handling "list data" that follows patterns of delegation of concerns and leaves for itself only one task - recycling items.

Why does Recycler View offers a better experience than List View?

The RecyclerView widget is a more advanced and flexible version of ListView.

  • RecyclerView was created as a ListView improvement,
  • In the RecyclerView model, several different components work together to display your data. The overall container for your user interface is a RecyclerView object that you add to your layout.
  • RecyclerView drastically improve performance
  • The RecyclerView fills itself with views provided by a layout manager that you provide.
  • Advantages of RecyclerView is

    • Efficiently Reuses cells while scrolling up/down
    • Decouples list from its container
    • Animations are decoupled and delegated to ItemAnimator
  • RecyclerView is a more flexible control for handling "list data" that follows patterns of delegation of concerns and leaves for itself only one task - recycling items

what is the difference between ScrollView, ListView, RecyclerView and WebView?

SCROLLVIEW

ScrollView is used to put different or same child views or layouts and the all can be scrolled.

Listview

ListView is used to put same child view or layout as multiple items. All these items are also scrollable.

Simply ScrollView is for both homogeneous and heterogeneous collection. ListView is for only homogeneous collection.

What is RecyclerView?

The RecyclerView widget is a more advanced and flexible version of ListView.

Why RecyclerView?

RecyclerView is a container for displaying large data sets that can be scrolled very efficiently by maintaining a limited number of views.

When you should use RecyclerView?

You can use the RecyclerView widget when you have data collections whose elements 
changes at runtime based on user action or network events.

WEBVIEW

WebView in Android turns the application into a web application. It comes from 
android.webkit.WebView. Here, the WebView class is an extension of Android's View
class which is used to show the web pages. WebView doesn't include all the features
of Web-browser-like navigation controls or an address bar etc.

What is the difference between ListView, AbsListView and RecyclerView

First, AbsListView is an abstract class and can't be used as a View element in application layout, although you can use it as a Base Class to implement your own View.
Before Lollipop, there wasn’t RecyclerView, it was introduced as a part of Material Design. It introduced a new way of handling listeners.

Starting from Lollipop it is considered as good practice to use RecyclerView instead of deprecated ListView.
