nopaginate's Introduction

NoPaginate

Android Arsenal androidweekly.cn Download API

Deprecated.

Android pagination library, based on @MarkoMilos repository Paginate

Loading Item Error Item

Gradle

implementation 'ru.alexbykov:nopaginate:0.9.9'

Install

  NoPaginate noPaginate = NoPaginate.with(recyclerView)
                .setOnLoadMoreListener(new OnLoadMoreListener() {
                    @Override
                    public void onLoadMore() {
                        //http or db request
                    }
                })
                .build();

If you use MVP or Clean Architecture, don't forget implement PaginateView. You can see example of implementation with MVP here

Actions

   noPaginate.showLoading(show);
   noPaginate.showError(show);
   noPaginate.setNoMoreItems(set); //Method onLoadMore will not to call
   noPaginate.unbind(); //Don't forget call it on onDestroy();

Custom Loading and Error

For custom error and loaging item just implement the interfaces ErrorItem or LoadingItem

Custom error:

public class CustomErrorItem implements ErrorItem {

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

           @Override
           public void onBindViewHolder(RecyclerView.ViewHolder holder, int position, final OnRepeatListener repeatListener) {
               Button btnRepeat = (Button) holder.itemView.findViewById(R.id.btnRepeat);
               btnRepeat.setOnClickListener(new View.OnClickListener() {
                   @Override
                   public void onClick(View v) {
                       if (repeatListener != null) {
                           repeatListener.onClickRepeat(); //call onLoadMore
                       }
                   }
               });
           }
}

Custom loading:

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

Install with custom items and trigger threshold

  NoPaginate noPaginate = NoPaginate.with(recyclerView)
                .setOnLoadMoreListener(new OnLoadMoreListener() {
                    @Override
                    public void onLoadMore() {
                        //http or db request
                    }
                })
                .setLoadingTriggerThreshold(5) //0 by default
                .setCustomErrorItem(new CustomErrorItem())
                .setCustomLoadingItem(new CustomLoadingItem())
                .build();

Idea

This repository is a slightly modified version of Paginate library. Author: @MarkoMilos

We decided to modify it a little, so that developers could easily use it with MVP or Clean Architecture

Roadmap

  1. Double-sided pagination
  2. Delegate for Presenter or Interactor, with implementation Limit/Offset and Page pagination
  3. Unit tests
  4. Wiki

nopaginate's Issues

Add an item to show that Adapter is empty

Can you add an Item in adapter to show that Adapter is empty? View can notify Paginate that the item-count has changed. If user enables this Empty Item and item-count reaches 0, you can show this item.

I use a layout to show Empty Adapter, but it is shown on top of RecyclerView in FrameLayout. I want to have it in Adapter, and be able to turn it on/off manually.

Thanks. Your library works amazingly even without this feature.

Support AndroidX?

Do you have plan to support androidX? There are the problem about RecyclerView.

NotifyDataSetChanged with payload not working

Hello,

First of all thanks for this library.

One thing noticed when I called notifyItemChanged(position, payload) it will call
onBindViewHolder(holder, position) not onBindViewHolder(holder, position, payload) .
Please handle this scenario.

Similarly other methods like onViewRecycled(), onViewAttachedToWindow(), onViewDetachedFromWindow() related methods are also not fired.

Thanks

forget to calculate loadmore item count

when I add code in your MianActivitylike :

 @Override
    protected void onPostCreate(@Nullable Bundle savedInstanceState) {
        super.onPostCreate(savedInstanceState);

        new Handler().postDelayed(() -> mainActivityPresenter.addItems(), 500);
    }

notice,it‘s a async action,now recyclerview only have one child(loadmore item), so it will cause load more twice,becase your code didn't calculcate loadmore item count(1)

Support for SwipeRefreshLayout or reloading whole list

I tried to implement swiperefresh with your library via this code

if (!isRefresh) {
    showProgressBar();
} else if (noPaginate != null) {
    noPaginate.unbind();
}
noPaginate = NoPaginate.with(listNews)
    .setOnLoadMoreListener(new OnLoadMoreListener() {
        @Override
        public void onLoadMore() {
           //network code
        }
    })
    .setLoadingTriggerThreshold(5)
    .build();

but it is not working, paginate is not going into the load more method

OnLoadMore called two times for lesser data

Firstly thanks for the great library i was able to remove a lot of boilerplate from my code.👍

My api call is supposed to load 10 items per page but since the data coming from first call is only 4 items this results in onLoadMore being called one more time.

First call for data

I noticed the load more calls without scroll, I initially had a first call to Retrofit to load data before scroll to load more.

So is there away to load initial data where I can have my loading view of choice?
Then when user scrolls, more are loaded??

RecyclerView inside NestedScrollView weird behavior

Hi @NoNews ,

I am using noPaginate lib ti handle a list of accounts movements, if I use the recyclerView [alone] the onLoadMore listener works fine when a reach the last item of the list, but when a Try to use NestedScrollView with RecyclerView the onLoadMore is called before I scroll down.

I hope you can Help me about this issue.

Cheers.

PD: I need to use NestedScrollView in order to use CollapsinToolbarLayout.

Cannot call this method in a scroll callback

I received an exception while scrolling horizontally. I modified ErrorItem and LoadingItem for Horizontal and Vertical scrolls.

public interface LoadingItem extends BaseLinearLayoutManagerItem {

    LoadingItem VERTICAL = new LoadingItem() {

        @Override
        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

            View view = LayoutInflater.from(parent.getContext()).inflate(
                    R.layout.pagination_item_loading, parent, false
            );

            return new RecyclerView.ViewHolder(view) {};
        }

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

    LoadingItem HORIZONTAL = new LoadingItem() {

        @Override
        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {

            View view = LayoutInflater.from(parent.getContext()).inflate(
                    R.layout.pagination_item_loading_horizontal_scroll, parent, false
            );

            return new RecyclerView.ViewHolder(view) {};
        }

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

And, then, I setOrientation() using PaginateBuilder:



    public PaginateBuilder setOrientation (PaginateOrientation orientation) {

        if (orientation == PaginateOrientation.HORIZONTAL) {
            setCustomErrorItem(ErrorItem.HORIZONTAL);
            setCustomLoadingItem(LoadingItem.HORIZONTAL);
        }
        else {
            setCustomErrorItem(ErrorItem.VERTICAL);
            setCustomLoadingItem(LoadingItem.VERTICAL);
        }

        return this;
    }

This is the exception I get:

03-24 10:06:48.274 W/RecyclerView: Cannot call this method in a scroll callback. Scroll callbacks mightbe run during a measure & layout pass where you cannot change theRecyclerView data. Any method call that might change the structureof the RecyclerView or the adapter contents should be postponed tothe next frame.

                                   	at android.vi

Proposed solution is to wrap these calls in a Handler.post() maybe.

Custom view when there is not more items to show

Hi @NoNews its me again.. lol.

Just one question,:

is it possible to show a custom view when there is not more items to show.?..I mean something like "There is not more items to show for the moment"

PD: something like the custom error view.

Regards.
