An Android library to retrofit multiple item view types.

Aug 4, 2016

The RecyclerView is one of the most used widgets in the Android world, and with it you have to implement an Adapter which provides the items for the view. Most use cases require the same base logic, but require you to write everything again and again.

The FastAdapter is here to simplify this process. You don't have to worry about the adapter anymore. Just write the logic for how your view should look like, and you are done.

Renderers is an Android library created to avoid all the Adapter/ListView boilerplate needed to create a new adapter and all the spaghetti code that developers used to create following the ViewHolder classic implementation.

This Android library offers you two main classes to extend and create your own rendering algorithms out of your adapter implementation.

Renderers is an easy way to work with android ListView and Adapter classes. With this library you only have to create your renderers and declare the mapping between the object to render and the renderer.

MergeAdapter accepts a mix of Adapters and Views and presents them as one contiguous whole to whatever ListView it is poured into. This is good for cases where you have multiple data sources, or if you have a handful of ordinary Views to mix in with lists of data, or the like.

Simply create a MergeAdapter and call addAdapter(), addView(), or addViews() (latter accepting a List), then attach your adapter to the ListView.

There is also MergeSpinnerAdapter for use with Spinner widgets.

SwipeActionAdapter is a library that provides a simple API to create Mailbox-like action when swiping in a ListView. The idea is to make it simple enough to implement while still providing sufficient options to allow you to integrate it with the design of your application.

  • Built-in support for DiffUtil (using Diffable)
  • Optimized performance - internal processing done on a background thread
  • 100% written in Kotlin
  • Modules:
    • Item Module
    • Paging Module
    • Emptiness Module

Creating adapters each time you want to use a RecyclerView is boring. Also, creating an adapter that accepts different types of data, with its corresponding views, and manage them generates adapters with lines and lines of code that are difficult to maintain.

RecyclerViewRenderers is a library whose main objective is to reduce the time you spend fighting against RecyclerView.

Composable adapters for Android RecyclerViews and ListViews.

ListView in Android supports header and footer views - views that do not belong to the underlying adapter but otherwise show up in the list and scroll along with the contents. However, they only work if you have not yet set your own adapter and are therefore not terribly flexible.

The SackOfViewsAdapter is another way of approaching this. Here, you provide the Views that make up the rows, and the adapter feeds them to Android as if they were newly created.

The SackOfViewsAdapter is designed to be sub-classed, mostly to determine how isEnabled() behaves, so you can control which of those views are selectable and which simply scroll with the list.

Android comes with a few "wrapper" classes, like CursorWrapper, that make it relatively easy for you to add just a bit of functionality to an existing object. The wrapper delegates all behaviors to the wrapped object; you just override the specific behaviors you need. This works well in cases where there are many possible underlying implementations, so you could not robustly accomplish these ends by subclassing.

Android lacks such a wrapper for ListAdapter, though. There is a WrappedListAdapter entry in the SDK, but it is an interface, not an implementation.

So, CWAC offers an AdapterWrapper to fill this void.

The easiest way to use a RecyclerView on Android.

StrictMode is a handy feature in API Level 9 and higher, telling you where your Android application is doing things it probably should not on the main application thread.

In the spirit of StrictMode, the StrictModeEx project offers classes to help you diagnose similar sorts of problems beyond what StrictMode itself offers.

Right now, that consists of one class: StrictAdapter. This ListAdapter wrapper will log slow-running getView() calls, plus optionally give you an overall performance view on how your Adapter is doing in the code you control.
