It stores list row views references and, thanks to this, calling the findViewById() method only occurs a couple of times, rather than for the entire dataset and on each bind view. The ViewHolder pattern allows us to make our list scrolling act smoothly. The recycler view was introduced with the support library in version 22.1.0 It was a part of the Material Design pack.Īs we have discussed the Limitations and problems with listviews now let’s discuss features of recycler view and let me explain how it works. There are many more problems and limitations with Listviews but I think these are the major and enough points to be discussed here and that’s how and that’s why Recyclerview came as a successor of it with improved functionality and better performance over listview. Whereas horizontal scrolling is a key concept in designing beautiful UI/UX and Google also uses it well in Google’s play store. Vertical ScrollingĪnother limitation is listview only has vertical scroll capability no Horizontal Lists. Recycler view tackles this problem very efficiently. Suppose we have a dataset of 100 thousand rows listview will create 100 thousand views at once it leads to consuming a lot of memory and listview behaves laggy. This problem occurs because listview tries to create as many rows the data have. Listview had a performance issue working with large datasets. When we talk about listview we always faced problems with it I am going to list down all those aspects below: Expensive Lagged Scrolling

I tried to simplify the definition above but a question arises what was the need of Recyclerview and why it came to existence. The Recyclerview provides improved performance, better management, and control for handling list data that follows patterns.
