Basic usage

/**
QuickRecyclerview takse three parameters:
List of your viewmodel for recyclerview item
Layout for recyclerview item
Bind id for recyclerview item (see the example layout file below)
*/
List<RecyclerviewItemViewModel> vmList = new ArrayList<>();
QuickRecyclerViewAdapter quickRecyclerViewAdapter = new QuickRecyclerViewAdapter<>(vmList, R.layout.layout_recyclerview_item, BR.vm);
RecyclerView recyclerView = findViewById(R.id.main_recycler_view);
recyclerView.setAdapter(quickRecyclerViewAdapter);

Example of layout file with DataBinding

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools">

  <data>

    <variable
      name="vm"
      type="com.eddystudio.quickrecyclerviewadapterdemo.RecyclerviewItemViewModel"/>
  </data>

  <android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <TextView
      android:id="@+id/title_tv"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      android:text="@{vm.title}"
	      ...
	/>

    <TextView
      android:id="@+id/decrip_tv"
      android:layout_width="0dp"
      android:layout_height="wrap_content"
      android:text="@{vm.description}"
	      ...
	/>
  </android.support.constraint.ConstraintLayout>
</layout>

Viewmodel class example

public class RecyclerviewItemViewModel {
  public final ObservableField<String> title = new ObservableField<>("");
  public final ObservableField<String> description = new ObservableField<>("");

  RecyclerviewItemViewModel(String title, String description) {
    this.title.set(title);
    this.description.set(description);
  }
}

Advance Usage

You also can extend QuickRecyclerViewBaseAdapter class to do more custom usage.

For example:

public class MyAdapter extends QuickRecyclerViewBaseAdapter {
  private final List<RecyclerviewItemViewModel> list;
  private final int layoutId = R.layout.layout_recyclerview_item;

  MyAdapter(List<RecyclerviewItemViewModel> list) {
    super(com.eddystudio.quickrecyclerviewadapterdemo.BR.vm);
    this.list = list;
  }

  @Override
  public void onBindViewHolder(@NonNull QuickRecyclerViewBaseAdapter.QuickRecyclerViewHolder quickRecyclerViewHolder, int i) {
    super.onBindViewHolder(quickRecyclerViewHolder, i);
    //quickRecyclerViewHolder.itemView.findViewById(...) 
    // you can get the view here to do whatever you want
  }

  public void setData(List<RecyclerviewItemViewModel> list) {
    this.list.clear();
    this.list.addAll(list);
    this.notifyDataSetChanged();
  }

  public void addDataInPos(int pos, RecyclerviewItemViewModel item) {
    this.list.add(pos, item);
    this.notifyItemInserted(pos);
  }

  // ... Do whatever you want for the adapter

  @Override
  protected Object getObjectForPosition(int position) {
    return list.get(position);
  }

  @Override
  protected int getLayoutIdForPosition(int position) {
    return getLayoutId();
  }

  @Override
  protected int getLayoutId() {
    return layoutId;
  }

  @Override
  public int getItemCount() {
    return list.size();
  }
}
