PagingRecycler

A quick way to implement a paging pattern for a RecyclerView. PagingRecycler will show a "loading" view at the bottom of your RecyclerView while you are waiting for a page of results from your api call, then remove it when you are finished.

Gradle

  allprojects {
        repositories {
            ...
            maven { url "https://jitpack.io" }
        }
    }

        dependencies {
            compile 'com.github.Batterii:PagingRecycler:v1.1'
    }

Usage

Adapter

public class MyAdapter extends PagingAdapter{

  private List<Item> myItems;

  public MyAdapter(){
    myItems = new ArrayList<>();
  }

  @Override
    public int getPagingLayout() {
        return R.layout.paging_item;
  }

  @Override
  public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    // Do your normal view creation

    // End with this
    return super.onCreateViewHolder(parent, viewType);

  }  

  @Override
  public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
    // Call super!
    super.onBindViewHolder(holder, position);

    // Do your normal binding

  }

  @Override
  public int getItemCount() {
    // just return super here
    return super.getItemCount();
  }

  @Override
  public int getPagingItemCount() {
    // return your actual item size here
    return myItems.size();
  }

}

Your Activity/Fragment etc.

public class MyActivity extends AppCompatActivity implements PagingDelegate.OnPageListener{

 @Override
  public void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);

      MyAdapter adapter = new MyAdapter();

      RecyclerView mRecycler = (RecyclerView)findViewById(R.id.my_recycler);

      PagingDelegate pagingDelegate = new PagingDelegate.Builder(adapter)
                .attachTo(mRecycler)
                .listenWith(this)
                .build();

      mRecycler.setAdapter(adapter);
  }

   @Override
    public void onPage(int offset) {
        // Perform your paging request
    }

    @Override
    public void onDonePaging() {

    }

  }
