Usage

how to import?

add this into gradle

// Yes, I have switched to jitpack.io.

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

dependencies {
    ...
    compile 'com.github.lsjwzh.RecyclerViewPager:lib:v1.1.2'
    ...
}

add proguard rules if need

-keep class com.lsjwzh.widget.recyclerviewpager.**
-dontwarn com.lsjwzh.widget.recyclerviewpager.**

Basic Usage:

It is easy to setup like a Recycler List View.

xml:

<com.lsjwzh.widget.recyclerviewpager.RecyclerViewPager
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:paddingLeft="15dp"
    android:paddingRight="15dp"
    app:rvp_triggerOffset="0.1"
    app:rvp_singlePageFling="true"
    android:clipToPadding="false"/>

code:

RecyclerViewPager mRecyclerView = (RecyclerViewPager) view.findViewById(R.id.list);

// setLayoutManager like normal RecyclerView, you do not need to change any thing.
LinearLayoutManager layout = new LinearLayoutManager(getActivity(),LinearLayoutManager.HORIZONTAL,false);
mRecyclerView.setLayoutManager(layout);

//set adapter
//You just need to impelement ViewPageAdapter by yourself like a normal RecyclerView.Adpater.
mRecyclerView.setAdapter(new RecyclerView.Adpater<X>());

// That is all.

Support TabLayout:

1.Add Dependency:

dependencies {
    ...
    compile 'com.github.lsjwzh.RecyclerViewPager:tablayoutsupport:v1.1.2'
    ...
}

2.Call 'setupWithViewPager'

TabLayout tabLayout = (TabLayout) findViewById(R.id.tabs);
TabLayoutSupport.setupWithViewPager(tabLayout, mRecyclerView, mAdapter);

Infinite Loop ViewPager:

<com.lsjwzh.widget.recyclerviewpager.LoopRecyclerViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:layout_marginTop="20dp"
        android:clipToPadding="false"
        android:paddingTop="15dp"
        android:paddingBottom="15dp"/>

You just need to use LoopRecyclerViewPager replace RecyclerViewPager. The usage of LoopRecyclerViewPager is the same as RecyclerViewPager. No matter what you specify position you want to scroll, LoopRecyclerViewPager will transform it to right position. Ex:In a LoopRecyclerViewPager with 10 items, scrollToPosition(1) will get same scroll behavior as scrollToPosition(11)、scrollToPosition(21) and so on.

How to get actual position in LoopRecyclerViewPager:

    int actualPosition = mLoopRecyclerViewPager.transformToActualPosition(adapterPosition);

If you just want to get current actual position, you can do it like this:

    int actualCurrentPosition = mLoopRecyclerViewPager.getActualCurrentPosition();
