One Adapter many Apps

📣 When initially Android team introduced the RecyclerView widget, we had to implement a custom Adapter in several applications, again and again to provide the items for our views.
We didn't know how to add selection and to combine all the use cases in the same Adapter. Since I created this library, it has become easy to configure multiple views and now, nobody wants to use a ListView anymore.

The idea behind is to regroup multiple features in a unique library, without the need to customize and import several third libraries not compatible among them.

The FlexibleAdapter helps developers to simplify this process without worrying too much about the Adapter anymore. It's easy to use, it has predefined logic for different situations and prevents common mistakes.
This library is configurable and it guides the developers to create a better user experience and now, even more with the new features.

Under the hood

Some simple features have been implemented, thanks to some Blogs (see at the bottom of the page), merged and methods have been improved for speed and scalability.

  • At lower level there is SelectableAdapter class. It provides selection features and it's able to maintain the state after the rotation: you just need to call the onSave/onRestore methods from the Activity!
  • At middle level, the AnimatorAdapter class has been added to give some animation at startup and when user scrolls.
  • At front level, the core class FlexibleAdapter. It holds and handles the main list, performs actions on all different types of item paying attention at the adding and removal of the items, as well as the new concept of "selection coherence".
  • New useful extensions and helpers have been added during the time to simplify the development.
  • Item interfaces and predefined ViewHolders complete the whole library giving more actions to the items and configuration options to developers.

Limitations

Item half swipe cannot be implemented due to how the android.support.v7.widget.helper.ItemTouchHelper is done, also clicks on rear view are not possible, same reason. Half swipe can be done with others means, please see issues #98 and #100. See also commits of Apr 25, 2016.
