###Sample

You can clone the project and compile it yourself (it includes a sample), or you can check it out already compiled at Google Play

Notice that it might not be the latest version

###Quick Setup（Basic Usage） ######1.Integration

repositories {
        jcenter()
    }
dependencies {
    ...
    compile 'com.marshalchen.ultimaterecyclerview:library:0.3.17'
}

#####2.Usage:

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:id="@+id/ultimate_recycler_view"
       >
        </com.marshalchen.ultimaterecyclerview.UltimateRecyclerView>

#####3.Features:
Loading more:

  ultimateRecyclerView.enableLoadmore();

 ultimateRecyclerView.setOnLoadMoreListener(new UltimateRecyclerView.OnLoadMoreListener() {
            @Override
            public void loadMore(int itemsCount, final int maxLastVisiblePosition) {
                Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                    public void run() {
                        simpleRecyclerViewAdapter.insert("More " + moreNum++, simpleRecyclerViewAdapter.getAdapterItemCount());
                    }
                }, 1000);
            }
        });

######Set ParallaxHeader:

 ultimateRecyclerView.setParallaxHeader(getLayoutInflater().inflate(R.layout.parallax_recyclerview_header, ultimateRecyclerView.mRecyclerView, false));
 
ultimateRecyclerView.setOnParallaxScroll(new UltimateRecyclerView.OnParallaxScroll() {
            @Override
            public void onParallaxScroll(float percentage, float offset, View parallax) {
                Drawable c = toolbar.getBackground();
                c.setAlpha(Math.round(127 + percentage * 128));
                toolbar.setBackgroundDrawable(c);
            }
        });

######Set swipe to refresh:

ultimateRecyclerView.setDefaultOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
            @Override
            public void onRefresh() {
                new Handler().postDelayed(new Runnable() {
                    @Override
                    public void run() {
                        simpleRecyclerViewAdapter.insert(moreNum++ + "  Refresh things", 0);
                        ultimateRecyclerView.setRefreshing(false);
                    }
                }, 1000);
            }
        });

######Set swipe to dismiss:

  ItemTouchHelper.Callback callback = new SimpleItemTouchHelperCallback(simpleRecyclerViewAdapter);
        mItemTouchHelper = new ItemTouchHelper(callback);
        mItemTouchHelper.attachToRecyclerView(ultimateRecyclerView.mRecyclerView);

Drag and drop:

  simpleRecyclerViewAdapter.setOnDragStartListener(new SimpleAdapter.OnStartDragListener() {
           @Override
           public void onStartDrag(RecyclerView.ViewHolder viewHolder) {
               mItemTouchHelper.startDrag(viewHolder);
           }
       });

Animations:

  ultimateRecyclerView.setItemAnimator(Type.values()[position].getAnimator());
  ultimateRecyclerView.getItemAnimator().setAddDuration(300);
  ultimateRecyclerView.getItemAnimator().setRemoveDuration(300);

######Showing and hiding toolbar and floating button:

  ultimateRecyclerView.setScrollViewCallbacks(new ObservableScrollViewCallbacks() {
            @Override
            public void onScrollChanged(int scrollY, boolean firstScroll, boolean dragging) {           
             }
            @Override
            public void onDownMotionEvent() {
            }
            @Override
            public void onUpOrCancelMotionEvent(ObservableScrollState observableScrollState) {
                if (observableScrollState == ObservableScrollState.DOWN) {
                     ultimateRecyclerView.showToolbar(toolbar, ultimateRecyclerView,getScreenHeight());
                } else if (observableScrollState == ObservableScrollState.UP) {
                      ultimateRecyclerView.hideToolbar(toolbar,ultimateRecyclerView,getScreenHeight());
                } else if (observableScrollState == ObservableScrollState.STOP) {
                }
            }
        });        

######Show empty view when the adapter is null:

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
...
app:recyclerviewEmptyView="@layout/empty_view"/>

OR

ultimateRecyclerView.setEmptyView(getResources().getIdentifier("empty_view","layout",getPackageName()));

ultimateRecyclerView.showEmptyView();

######Show custom FloatingView(Both menu and button are fine. It is easy to set click event on them) when the adapter is null:

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
...
 app:recyclerviewFloatingActionView="@layout/floating_view"/>

######Set custom colorful style of pull to refresh:

 <com.marshalchen.ultimaterecyclerview.CustomUltimateRecyclerview
 .../>

######Using CustomUltimateRecyclerview instead of UltimateRecyclerView ultimateRecyclerView.setCustomSwipeToRefresh();

######Set scrollbars of RecyclerView by set attributes of UltimateRecyclerView in xml layout:

<com.marshalchen.ultimaterecyclerview.UltimateRecyclerView
        app:recyclerviewScrollbars="vertical" />                

Note that set scrollbars of RecyclerView dynamically by code is NOT SUPPORTED refer to this

######Add sticky header:

In MainActivity:

   StickyRecyclerHeadersDecoration headersDecor = new StickyRecyclerHeadersDecoration(simpleRecyclerViewAdapter);
  ultimateRecyclerView.addItemDecoration(headersDecor);

In the adapter:

 @Override
    public long generateHeaderId(int position) {
        if (getItem(position).length() > 0)
            return getItem(position).charAt(0);
        else return -1;
    }
    @Override
    public RecyclerView.ViewHolder onCreateHeaderViewHolder(ViewGroup viewGroup) {
        View view = LayoutInflater.from(viewGroup.getContext())
                .inflate(R.layout.stick_header_item, viewGroup, false);
        return new RecyclerView.ViewHolder(view) {
        };
    }

Refresh adapter:

mAdapter.registerAdapterDataObserver(new RecyclerView.AdapterDataObserver() {
      @Override public void onChanged() {
        headersDecor.invalidateHeaders();
      }
    });

######Using different layout in an adapter: You should define a MultiViewAdapter which extends UltimateDiffernetViewTypeAdapter and then your custom differnt view adapters.

public class MultiViewTypesRecyclerViewAdapter extends UltimateDifferentViewTypeAdapter{
    @Override
    public Enum getEnumFromPosition(int position) {
        if (position % 2 == 1) {
            return SampleViewType.SAMPLE1;
        } else {
            return SampleViewType.SAMPLE2;
        }
    }
    
    public MultiViewTypesRecyclerViewAdapter(List<String> dataSet) {
      putBinder(SampleViewType.SAMPLE1, new Sample1Binder(this,dataSet));
      putBinder(SampleViewType.SAMPLE2, new Sample2Binder(this,dataSet));
      ...
    }
    ...
}

public class Sample1Binder extends DataBinder<Sample1Binder.ViewHolder> {
   
    @Override
    public ViewHolder newViewHolder(ViewGroup parent) {
        View view = LayoutInflater.from(parent.getContext()).inflate(
                R.layout.simple_binder1, parent, false);
        return new ViewHolder(view);
    }
    ...
}
    

######Admob implementation

 private AdView createadmob() {
        AdView mAdView = new AdView(this);
        mAdView.setAdSize(AdSize.MEDIUM_RECTANGLE);
        mAdView.setAdUnitId("__GOOGLE_AD_UNIT__ID__");
        mAdView.setLayoutParams(new ViewGroup.LayoutParams(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT));

        // Create an ad request.
        AdRequest.Builder adRequestBuilder = new AdRequest.Builder();

        if (admob_test_mode)
            // Optionally populate the ad request builder.
            adRequestBuilder.addTestDevice(AdRequest.DEVICE_ID_EMULATOR);

        // Start loading the ad.
        mAdView.loadAd(adRequestBuilder.build());
        return mAdView;
    }

       simpleRecyclerViewAdapter = new admobdfpadapter(createadmob(), 5, stringList, new AdmobAdapter.AdviewListener() {
            @Override
            public AdView onGenerateAdview() {
                return createadmob();
            }
        });

######Loading adapter with animations :

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
       ...
        if (!isFirstOnly || position > mLastPosition) {
            for (Animator anim : getAdapterAnimations(holder.itemView, AdapterAnimationType.ScaleIn)) {
                anim.setDuration(mDuration).start();
                anim.setInterpolator(mInterpolator);
            }
            mLastPosition = position;
        } else {
            ViewHelper.clear(holder.itemView);
        }

    }
