mugen

mugen is a microlibrary for implementing infinite scroll on Android.

Features

  • Add infinite scroll to your lists with a few lines of code.
  • Configuration allows you to decide how and when to trigger loading. You can even disable load more when all items have been fetched for network usage optimization.
  • Supports both AbsListView and RecyclerView! Which means it's one single library to enable infinite scroll for ListView, GridView and RecyclerView instances.

Usage

    //mCollectionView can be a ListView, GridView, RecyclerView or any instance of AbsListView!
    BaseAttacher attacher = Mugen.with(mCollectionView, new MugenCallbacks() {
            @Override
            public void onLoadMore() {
                /* Will be triggered when the next page has to be loaded.
                *
                * Do your load operation here.
                * Note: this is NOT asynchronous!
                */
            }

            @Override
            public boolean isLoading() {
                /* Return true if a load operation is ongoing. This will
                * be used as an optimization to prevent further triggers
                * if the user scrolls up and scrolls back down before 
                * the load operation finished.
                * 
                * If there is no load operation ongoing, return false
                */
                return isLoading;
            }

            @Override
            public boolean hasLoadedAllItems() {
                /*
                * If every item has been loaded from the data store, i.e., no more items are
                * left to fetched, you can start returning true here to prevent any more
                * triggers of the load more method as a form of optimization.
                *
                * This is useful when say, the data is being fetched from the network
                */
                return false;
            }
        }).start();

        /* Use this to dynamically turn infinite scroll on or off. It is enabled by default */
        attacher.setLoadMoreEnabled(true); 
        
        /* Use this to change when the onLoadMore() function is called. 
        * By default, it is called when the scroll reaches 2 items from the bottom */
        attacher.setLoadMoreOffset(4); 
        
        /*
        * mugen uses an internal OnScrollListener to detect and trigger load events.
        * If you need to listen to scroll events yourself, you can set this and 
        * mugen will automatically forward all scroll events to the listener.
        */
        attacher.setOnScrollListener(listener);

Notes

mugen will only start working AFTER there are enough items in the list to make it scrollable. Ensure that you load at least enough data first so that the list becomes scrollable.

Installation

There are two ways you can install mugen.

As a gradle dependency(preferred)

Add the line compile 'com.vinaysshenoy:mugen:1.0.2' to your dependencies section in your build.gradle script

Cloning and adding

  1. Clone the repository
  2. Copy the library folder into your project root.
  3. Add the line include ':library' to your settings.gradle file
  4. Then, add the line compile project(':library') to the build.gradle file in your main project.
  5. Do a Gradle sync, and you should be good to go!
