Gradle Usage

Add it in your root build.gradle at the end of repositories:

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

Step 2. Add the dependency

dependencies {
        compile 'com.github.GauravChaddha1996:CDSRecyclerView:1.5'
}

Usage

Drag and swipe functionality is disabled by defualt.Use the enable functions to add them after recycler view initialization

Without extending CdsRecyclerViewAdapter the drag and swipe functionality won't be present

Include the CdsRecyclerView in your layout:

<com.gaurav.cdsrecyclerview.CdsRecyclerView
    android:id="@+id/recyclerView"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

</com.gaurav.cdsrecyclerview.CdsRecyclerView>

Create a recycler view adapter extending CdsRecyclerViewAdapter to get add, remove, drag and swipe functionality.

(Note: Without extending CdsRecyclerViewAdapter the drag and swipe functionality won't be present)

  public class RecyclerViewAdapter extends CdsRecyclerViewAdapter<String, RecyclerViewAdapter.MyViewHolder> {
  
  private Context mContext;
  
  public RecyclerViewAdapter(Context context, List<String> list) {
      super(context, list);
      mContext = context;
  }
  
  @Override
  public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
      return new MyViewHolder(LayoutInflater.from(mContext).inflate(R.layout.your_item_layout, parent, false));
  }
  
  // note that we override the bindHolder custom function to get back the
  // custom view holder instead of the usual onBindViewHolder()
  @Override
  public void bindHolder(MyViewHolder holder, int position) {
      holder.mTextView.setText(getList().get(position));
  }

  public class MyViewHolder extends RecyclerView.ViewHolder {
      TextView mTextView;

      public MyViewHolder(View itemView) {
          super(itemView);
          mTextView = (TextView) itemView.findViewById(R.id.item_recycler_view_text);
      }
  }
}

Initialize the Cdsrecycler view as you would for a normal recycler view

mRecyclerView = new CdsRecyclerView(this);
mRecyclerView = (CdsRecyclerView) findViewById(R.id.recyclerView);
mRecyclerView.setHasFixedSize(true);
mRecyclerView.setLayoutManager(new LinearLayoutManager(this));
//or any other layout manager

Set the Adapter

mRecyclerViewAdapter = new RecyclerViewAdapter(this, getData());
mRecyclerView.setAdapter(mRecyclerViewAdapter);

Setting on item click,long press, drag, swipe and load more listener functionality

mRecyclerView.setItemClickListener(new CdsRecyclerView.ItemClickListener() {
        @Override
        public void onItemClick(int position) {
        
            Toast.makeText(MainActivity.this, "Item Clicked:" +
                    mRecyclerViewAdapter.getItem(position), Toast.LENGTH_SHORT).show();
        
        }
    });
    
mRecyclerView.setItemLongPressListener(new CdsRecyclerView.ItemLongPressListener() {
        @Override
        public void onItemLongClick(int position) {
    
            Toast.makeText(MainActivity.this, "Item Long Clicked:" +
                    mRecyclerViewAdapter.getItem(position), Toast.LENGTH_SHORT).show();
    
        }
    });
    
mRecyclerView.enableItemSwipe();
mRecyclerView.enableItemDrag();
mRecyclerView.setOnLoadMoreListener(new CdsRecyclerView.LoadMoreListener() {
          @Override
          public void onLoadMore() {
              // do your loading here, maybe show a progress bar before loading after loading is done,
  		// remove the progress bar and remember to do the following- Set the loading in recycler
  		// view as false
  		mRecyclerView.setLoading(false);
  		//You can remove the load more listener like this
  		mRecyclerView.removeOnLoadMoreListener();
          }
      }, 5);
