RecyclerView的快速和易于使用的Adapter：FastAdapter

jopen 9年前

FastAdapter

RecyclerView是Android中最常用的组件之一，使用RecyclerView的时候，必须实现Adapter中提供的相应接口。所以每次调用RecyclerView时，就需要重复实现Adapter中的这些方法。FastAdapter就是用来解决重用问题的，使用FastAdapter后，我们就只需关心item与view的部分就可以了。

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/item should look like, and you are done. This library has a fast and highly optimized core which provides core functionality, most apps require. It also prevents common mistakes by taking away those steps from the devs. Beside being blazing fast, minimizing the code you need to write, it is also really easy to extend. Just provide another Adapter implementation, hook into the adapter chain, custom select / deselection behaviors. Everything is possible.

A quick overview:

  • Click / Long-Click listeners
  • Selection / Multi-Selection
  • Expandable items
  • Write less code, get better results
  • Simple Drag & Drop
  • Headers
  • Footers
  • Highly optimized code
  • Includes suggestions from the Android Team
  • Easily extensible
  • Chain other Adapters
  • Comes with useful Helpers
    • ActionModeHelper
    • More to come...

How to use

1. Implement your item (the easy way)

Just create a class which extends the AbstractItem as shown below. Implement the methods, and your item is ready.

public class SampleItem extends AbstractItem<SampleItem, SampleItem.ViewHolder> {      public String name;      public String description;        //The unique ID for this type of item      @Override      public int getType() {          return R.id.fastadapter_sampleitem_id;      }        //The layout to be used for this type of item      @Override      public int getLayoutRes() {          return R.layout.sample_item;      }        //The logic to bind your data to the view      @Override      public void bindView(ViewHolder viewHolder) {          //call super so the selection is already handled for you          super.bindView(viewHolder);            //bind our data          //set the text for the name          viewHolder.name.setText(name);          //set the text for the description or hide          viewHolder.description.setText(description);      }        //The viewHolder used for this item. This viewHolder is always reused by the RecyclerView so scrolling is blazing fast      protected static class ViewHolder extends RecyclerView.ViewHolder {          protected TextView name;          protected TextView description;            public ViewHolder(View view) {              super(view);              this.name = (TextView) view.findViewById(com.mikepenz.materialdrawer.R.id.material_drawer_name);              this.description = (TextView) view.findViewById(com.mikepenz.materialdrawer.R.id.material_drawer_description);          }      }  }

2. Set the Adapter to the RecyclerView

//create our FastAdapter which will manage everything  FastItemAdapter fastAdapter = new FastItemAdapter();    //set our adapters to the RecyclerView  //we wrap our FastAdapter inside the ItemAdapter -> This allows us to chain adapters for more complex useCases  recyclerView.setAdapter(fastAdapter);    //set the items to your ItemAdapter  fastAdapter.add(ITEMS);
