OmegaRecyclerView

Custom RecyclerView with additional functionality. Allow you add divider, itemSpace, emptyView, sticky header and some other features

Installation

To get a Git project into your build:

Step 1. Add the JitPack repository to your build file

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

Step 2. Add the dependency

dependencies {
    implementation 'com.github.Omega-R:OmegaRecyclerView:1.7.1@aar'
}

Usage

Example of usage in xml layout

com.omega_r.libs.omegarecyclerview.OmegaRecyclerView
        android:id="@+id/custom_recycler_view"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:divider="#888"
        android:dividerHeight="1dp"
        app:itemSpace="12dp"
        app:showDivider="middle"/>

StickyHeader

To add sticky header into project you need implements StickyHeaderAdapter in adapters class

public class TestAdapter extends RecyclerView.Adapter<TestAdapter.ViewHolder>
        implements StickyHeaderAdapter<TestAdapter.HeaderHolder>

Proper appearence of sticky header when using space item

stickyHeaderDecoration.setItemSpace(omegaRecyclerView.getItemSpace());

You can use findViewById without itemView

nameTextView = findViewById(R.id.text_contact_name);
messageButton = findViewById(R.id.button_message);

For array use BaseArrayAdapter

getItemCount()
getItem(position)
set(array)
add(array)

SwipeMenu

To add swipe menu into project you need to use SwipeViewHolder or create your own ViewHolder.

public class ViewHolder extends SwipeViewHolder {

    public ViewHolder(ViewGroup parent) {
            super(parent, 
            R.layout.item_swipe_content, 
            R.layout.item_left_swipe_menu, 
            R.layout.item_right_swipe_menu);
    }        

Also you can use constructor only with left menu, or only with right menu.

    public ViewHolder(ViewGroup parent) {
            super(parent, 
            R.layout.item_swipe_content, 
            R.layout.item_left_swipe_menu, 
            SwipeViewHolder.NO_ID);
    }

Also you can use one layout for left menu and right menu.

    public ViewHolder(ViewGroup parent) {
            super(parent, 
            R.layout.item_swipe_content, 
            R.layout.swipe_menu);
    }

You can use following methods for controlling swipe menu state:

public void setSwipeFractionListener(@Nullable SwipeFractionListener listener);
public void setSwipeListener(@Nullable SwipeSwitchListener listener);
public void smoothCloseMenu(int duration);
public void smoothCloseMenu();
public void smoothOpenBeginMenu();
public void smoothOpenEndMenu();
public void setSwipeEnable(boolean enable);
public boolean isSwipeEnable();

Pagination

To add pagination into project you just need to setPaginationCallback to OmegaRecyclerView.

mRecyclerView.setPaginationCallback(new OnPageRequestListener() {
            @Override
            public void onPageRequest(int page) {
                // You can load data inside this callback
            }

            @Override
            public int getPagePreventionForEnd() {
                return PREVENTION_VALUE; // PREVENTION_VALUE - for how many positions until the end you want to be informed
            }
        });

How to control pagination:

mRecyclerView.showProgressPagination(); // show progress
mRecyclerView.hidePagination(); // hide pagination
mRecyclerView.showErrorPagination(); // show error

You have two ways to add your custom pagination layout and error layout. First way:

<com.omega_r.libs.omegarecyclerview.OmegaRecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:paginationLayout="@layout/item_progress"
        app:paginationErrorLayout="@layout/item_error_loading"/>
        

You can implement PaginationView in your Adapter class. Second:

public class RecyclerAdapter extends OmegaRecyclerView.Adapter<RecyclerView.ViewHolder> implements PaginationViewCreator {
....
@Nullable
    @Override
    public View createPaginationView(ViewGroup parent, LayoutInflater inflater) {
        return inflater.inflate(R.layout.item_progress, parent, false);
    }

    @Nullable
    @Override
    public View createPaginationErrorView(ViewGroup parent, LayoutInflater inflater) {
        View view = inflater.inflate(R.layout.item_error_loading, parent, false);
        view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                // on error clicked....
            }
        });
        return view;
    }

Sections (Header, Footer)

For usage just add you Views inside OmegaRecyclerView and add "app:layout_section" parameter.

<?xml version="1.0" encoding="utf-8"?>
<com.omega_r.libs.omegarecyclerview.OmegaRecyclerView 
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <TextView
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:text="Header"
        app:layout_section="header"/>

    <TextView
        android:layout_width="match_parent"
        android:layout_height="100dp"
        android:text="Footer"
        app:layout_section="footer"/>

</com.omega_r.libs.omegarecyclerview.OmegaRecyclerView>

For controll

OmegaRecyclerView.setHeadersVisibility(true);
OmegaRecyclerView.setFootersVisibility(false);

ViewPager

For usage just add OmegaPagerRecyclerView

<?xml version="1.0" encoding="utf-8"?>
    <com.omega_r.libs.omegarecyclerview.viewpager.OmegaPagerRecyclerView
        android:id="@+id/recyclerview"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"

        // Supported features
        app:infinite="true"   // Infinite scroll
        app:pageSize="0.8" // set page size 80% of screen
        app:transitionTime="2100"/>

You could use your owner transformation.

        recyclerView.setItemTransformer(new ScaleTransformer.Builder()
                                                            .setMaxScale(1.1f)
                                                            .setMinScale(0.8f)
                                                            .build());

You could see our otransformations on wiki page.
