MjolnirRecyclerView

Provides a simple way to extend the default RecyclerView behaviour with support for headers, footers, empty view, DiffUtil and ArrayAdapter like methods.

Usage

Add the library as a dependency to your build.gradle

compile 'co.infinum:mjolnirrecyclerview:version@aar'

Check the latest version here.

Features

1. Header & footer support

Add a custom number of headers and footers to MjolnirRecyclerView by using 2 simple methods from MjolnirRecyclerAdapter:

 adapter.setHeader(View view)
  adapter.setHeader(View view)

2. Empty view

Empty view support for MjolnirRecyclerView. View is automatically hidden when adapter is populated with some data, and is automatically shown once again when adapter becomes empty.

 recyclerView.setEmptyView(View view)

You can also show empty view while adapter is not set to the MjolnirRecyclerView, which is handy if you want to intialize adapter at some later point in the time.

 // show empty view if adapter is not set
  recyclerView.setEmptyView(View view, true)

3. DiffUtil

DiffUtil support for MjolnirRecyclerAdapter. Simply add DiffUtil.Callback in adapters update method:

 adapter.update(new ItemDiffUtilResult())

As DiffUtil is a blocking sync action, it's executed on the background thread inside the MjolnirRecyclerAdapter by using a AsyncTask. As a result of this approach, you need to call cancel() method on your adapter when your activity or fragment is about to be destroyed, so that the adapter is not updated if the screen has been destroyed.

 @Override
  protected void onDestroy() {

super.onDestroy();

adapter.cancel();

  
}

4. ArrayAdapter like methods

MjolnirRecyclerAdapter has full support for ArrayAdapter methods, like add(), addAll(), reset(), remove(), set()...
