Gradle dependency:

compile 'homhomlin.lib:ptrrv-library:1.3.1'

or

Maven dependency:

<dependency>
	<groupId>homhomlin.lib</groupId>
	<artifactId>ptrrv-library</artifactId>
	<version>1.3.1</version>
</dependency>

##Usage

PullToRefreshRecyclerView is easy to use just like ListView and RecyclerView. It is derived from native SwipeRefreshLayout, so all property of SwipeRefreshLayout can be used here.

See Sample for detail.

First: Config in xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <com.lhh.ptrrv.library.PullToRefreshRecyclerView
        android:id="@+id/ptrrv"
        android:layout_width="match_parent"
        android:layout_height="match_parent"/>

</RelativeLayout>

Second: Find it in your Activity

PullToRefreshRecyclerView mPtrrv = (PullToRefreshRecyclerView) this.findViewById(R.id.ptrrv);

Third: Config it in java code

// custom own load-more-view and add it into ptrrv
DemoLoadMoreView loadMoreView = new DemoLoadMoreView(this, mPtrrv.getRecyclerView());
loadMoreView.setLoadmoreString(getString(R.string.demo_loadmore));
loadMoreView.setLoadMorePadding(100);

mPtrrv.setLoadMoreFooter(loadMoreView);

//remove header
mPtrrv.removeHeader();

// set true to open swipe(pull to refresh, default is true)
mPtrrv.setSwipeEnable(true);

// set the layoutManager which to use
mPtrrv.setLayoutManager(new LinearLayoutManager(this));

// set PagingableListener
mPtrrv.setPagingableListener(new PullToRefreshRecyclerView.PagingableListener() {
    @Override
    public void onLoadMoreItems() {
        //do loadmore here
    }
});

// set OnRefreshListener
mPtrrv.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
    @Override
    public void onRefresh() {
        // do refresh here
    }
});

// add item divider to recyclerView
mPtrrv.getRecyclerView().addItemDecoration(new DividerItemDecoration(this,
        DividerItemDecoration.VERTICAL_LIST));

// add headerView
mPtrrv.addHeaderView(View.inflate(this, R.layout.header, null));

//set EmptyVIEW
mPtrrv.setEmptyView(View.inflat(this,R.layout.empty_view, null));

// set loadmore String
mPtrrv.setLoadmoreString("loading");

// set loadmore enable, onFinishLoading(can load more? , select before item)
mPtrrv.onFinishLoading(true, false);

Finally: Set the adapter which extends RecyclerView.Adpater

PtrrvAdapter mAdapter = new PtrrvAdapter(this);
mPtrrv.setAdapter(mAdapter);
