Android RecyclerView is used to create advance lists and cards or grids with material design concept in your android application. The onBindViewHolder method is where you set the data on the view. I want to build a calendar in list with recycler view …. Because we are removing every item manually in a for loop (because List lacks a method to remove a multiple items at once similar to list.addAll()).

Like any good freshbytelabs Android developer, one of my main goals is to write clean code, code that never obscures the designer's intent but rather is full of crisp abstractions and straightforward lines of control,” as author Grady Booch put it I have found that using data binding with the Model-View-ViewModel (MVVM) architectural pattern and RecyclerView accomplishes many of the objectives of clean coding, including reducing the requirement for boilerplate code, facilitating code decoupling and improving readability and testability—not to mention reducing development time.

The idea behind the ItemTemplateSelector class is that you then do not have to extend the MvxRecylcerAdapter, to provide different Views for different ViewModel types. Here is the full blown RecyclerView.Adapter for the stock prices. Initialize ItemTouchHelper with the callback behavior you defined, and then attach it to the RecyclerView.

I wasn't the original developer who began this project (although I took over the project at an early stage of development), but the previous developer made the decision to utilize RecyclerViews to render out various different ViewHolders dependent on the data that we received from the API.

If you're using SearchView, call filter() in its onQueryTextSubmit(String s) and onQueryTextChange(String s) methods. Ovverride the required method and complete the code content as shown below. ItemDecoration (As the name suggests) should be used to decorate view items of the RecyclerView.
