RecyclerAdapter

This library contains a set of RecyclerAdapter with different functionalities.

There is an adapter for each combination of following features:

• Data Source:
• Arrays
• Cursor
• List Type:
• linear
• tree
• expandable
• Data Mapping:
• Array element to view ID
• Cursor to view ID
• DataBinding

Example

In this repository is a sample app. You can see how you can use different RecyclerAdapter.

This is a simple example for a CursorRecyclerAdapter:

recyclerAdapter = new CursorRecyclerAdapter(
        R.layout.container_simple_element,
        new String[]{
                "text"
        },
        new int[] {
                R.id.textView1
        });

recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(recyclerAdapter);

And this is for expandable RecyclerAdapter based on Cursors and DataBinding

ExpandableCursorDataBindingRecyclerAdapter recyclerAdapter = new ExpandableCursorDataBindingRecyclerAdapter(
        new BindingInformation(
                ViewTypeConstants.VIEW_TYPE_DEFAULT,
                R.layout.container_expandable_databinding_cursor_child,
                BR.cursor
        ),
        new BindingInformation(
                ViewTypeConstants.VIEW_TYPE_GROUP,
                R.layout.container_expandable_databinding_cursor_group,
                BR.cursor
        )
);

recyclerView.setLayoutManager(new LinearLayoutManager(this));
recyclerView.setAdapter(recyclerAdapter);

Please note: For Cursor based RecyclerAdapter you need to do the queries yourself and set the resulting Cursors to the RecyclerAdapter.

Customizing

The library is based on one BasicRecyclerAdapter with a custom RecyclerAdapterDataSource as data source and a RecyclerAdapterViewHandler for mapping your data to views.

You can easily create your custom RecyclerAdapter or expand one of the other RecyclerAdapters.
