Description

This is an attempt to make RecyclerView easier to use.

Features built in:

• ProgressBar while adapter hasn't been set
• EmptyView if adapter is empty
• SwipeRefreshLayout (Google's one)
• Infinite scrolling, when you reach the X last item, load more of them.
• Swipe To Dismiss or Swipe To Remove
• Sticky headers (via Eowise, see sample)

Integration

Just add it to you dependencies

    compile 'com.malinskiy:superrecyclerview:$version'

Usage

• Use directly SuperRecyclerView:

   <com.malinskiy.superrecyclerview.SuperRecyclerView
            android:id="@+id/list"
            xmlns:app="http://schemas.android.com/apk/res-auto"
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            app:layout_empty="@layout/emptyview"
            app:layout_moreProgress="@layout/view_more_progress"
            app:mainLayoutId="@layout/layout_recyclerview_verticalscroll"
            app:recyclerClipToPadding="false"
            app:recyclerPadding="16dp"
            app:scrollbarStyle="insideInset"/>

• Current Attributes supported:

  <attr name="layout_empty" format="reference"/>
  <attr name="layout_moreProgress" format="reference"/>
  <attr name="layout_progress" format="reference"/>
  <attr name="recyclerClipToPadding" format="boolean"/>
  <attr name="recyclerPadding" format="dimension"/>
  <attr name="recyclerPaddingTop" format="dimension"/>
  <attr name="recyclerPaddingBottom" format="dimension"/>
  <attr name="recyclerPaddingLeft" format="dimension"/>
  <attr name="recyclerPaddingRight" format="dimension"/>
  <attr name="scrollbarStyle">
      <flag name="insideOverlay" value="0x0"/>
      <flag name="insideInset" value="0x01000000"/>
      <flag name="outsideOverlay" value="0x02000000"/>
      <flag name="outsideInset" value="0x03000000"/>
  </attr>
  
  <attr name="mainLayoutId" format="reference"/>

SuperRecyclerView Java Usage

    recycler.setRefreshListener(new SwipeRefreshLayout.OnRefreshListener {
      @Override
      public void onRefresh() {
          // Do your refresh
      });

    // when there is only 10 items to see in the recycler, this is triggered
    recycler.setupMoreListener(new OnMoreListener() {
      @Override
      public void onMoreAsked(int numberOfItems, int numberBeforeMore, int currentItemPos) {
        // Fetch more from Api or DB
      }}, 10);

    recycler.setupSwipeToDismiss(new SwipeDismissListViewTouchListener.DismissCallbacks() {
      @Override
      public boolean canDismiss(int position) {
        return true
      }

      @Override
      public void onDismiss(RecyclerView recyclerView, int[] reverseSortedPositions) {
        // Do your stuff like call an Api or update your db
      }});

Scrollbars

RecyclerView currently doesn't support setting scrollbars from code that's why I can't parse custom attributes. You have to use appropriate mainLayoutId attribute to have scrollbars visible.

Vertical scrollbars

<com.malinskiy.superrecyclerview.SuperRecyclerView
     app:mainLayoutId="@layout/layout_recyclerview_verticalscroll"
     app:scrollbarStyle="insideInset"
     .../>

Horizontal scrollbars

<com.malinskiy.superrecyclerview.SuperRecyclerView
     app:mainLayoutId="@layout/layout_recyclerview_horizontalscroll"
     app:scrollbarStyle="insideInset"
     .../>

Swipe layout

1. You should always assign android:id to @id/recyclerview_swipe. Note that it's a reference to an already defined id, so don't use @+id

2. The SwipeLayout can only have 2 children that are instances of ViewGroup, e.g. LinearLayout, RelativeLayout, GridLayout

3. The first child is the bottom view, the second child is the top view

4. Your adapter should extend BaseSwipeAdapter class

5. Do not setup swipe to dismiss and use swipe layout at the same time. If you do - a kitten will cry somewhere.

Item example:

<com.malinskiy.superrecyclerview.swipe.SwipeLayout
    android:id="@id/recyclerview_swipe"
    xmlns:swipe="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    swipe:horizontalSwipeOffset="16dp">

    <LinearLayout
        ...
    </LinearLayout>

    <LinearLayout
        ...
    </LinearLayout>

</com.malinskiy.superrecyclerview.swipe.SwipeLayout>

Custom attributes supported:

    <attr name="drag_edge" format="enum">
        <enum name="left" value="0"/>
        <enum name="right" value="1"/>
        <enum name="top" value="2"/>
        <enum name="bottom" value="3"/>
    </attr>
    <attr name="horizontalSwipeOffset" format="dimension"/>
    <attr name="verticalSwipeOffset" format="dimension"/>
    <attr name="show_mode" format="enum">
        <enum name="lay_down" value="0"/>
        <enum name="pull_out" value="1"/>
    </attr>
