Preview

Setup

TODO JCenter

Usage

Use the default implementation to start quickly.

BKLoadMore mBKLoadMore = BKLoadMoreImpl.with(recyclerView, this).build();

Implement the CallBacks interface to control paging action.

@Override
public void onLoadMore() {
    // Called when next page of data needs to be loaded.
    handler.postDelayed(fakeCallback, 1500);
}

@Override
public void onRetry() {
    // Called when the next page of data needs to be reloaded.
    handler.postDelayed(retryCallback, 1500);
}

Call the following method at the appropriate time, see the note for details.

// Called to check if there is more data (more pages) to load.
mBKLoadMore.setIsLastPage(isLastPage);

// This method is called when the data has been loaded.
mBKLoadMore.completedLoadMore();

// This method is called when data loading fails.It will show the load failed line.
mBKLoadMore.loadMoreFail();

Note: LayoutManager and RecyclerView.Adapter needs to be set before calling the code above.

Customize

mBKLoadMore = BKLoadMoreImpl.with(recyclerView, this)
                            .setLoadingItem(new CustomerLoadingItem())
                            .setNoMoreDataItem(new CustomerNoMoreDataItem())
                            .build();

Implement the LoadingItem interface to customize the loading line.

CustomerLoadingItem.java

public class CustomerLoadingItem implements LoadingItem {
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.loading_row_customer, parent, false);
        return new RecyclerView.ViewHolder(view) {
        };
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {

    }
}

Implement the NoMoreDataItem interface to customize the showing no more data line.

CustomerNoMoreDataItem.java

public class CustomerNoMoreDataItem implements NoMoreDataItem {
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.no_more_data_row_customer, parent, false);
        return new RecyclerView.ViewHolder(view) {
        };
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {

    }
}

加载更多问题

你好，下载demo运行，发现当数据不满一页的时候，也会触发加载更多逻辑?请问这个逻辑怎么修改

RecyclerView设置LayoutManager为StaggeredGridLayoutManager时，数据全部加载完了，却一直显示正在加载的状态

  非常感谢作者提供这个库，在使用的过程中发现了点问题：

1、recyclerView.setLayoutManager(new StaggeredGridLayoutManager(3, StaggeredGridLayoutManager.VERTICAL)); 数据全部加载完了，却一直显示加载中的状态。

2、recyclerView.setLayoutManager(new GridLayoutManager(this, 3)); 加载失败的item没有占满整个屏幕的宽，只是占据GridView的item宽度。

onAdapterDataChanged() 方法中调用了displayRow()方法，接着在checkEndOffset()方法中又调用了displayRow()方法，是不是重复调用了，我注释掉了onAdapterDataChanged() 方法中的displayRow()方法，再次运行后发现效果是一样的。
希望作者看到后能及时修复一下，谢谢。
