RecyclerAdapter (Easy sample method)

CustomerViewHolder.class :

@BindLayoutRes(R.layout.{name_of_your_layout})
public class CustomerViewHolder extends RecyclerViewHolder<Customer> {
    TextView mText;
    CustomerViewHolder(View view){
        super(view);
        mText = view.findViewById(R.id.text1);
    }
    
    void onBind(Customer item){
        //todo implements
    }
}

MainFragment.class

public class MainFragment extends Fragment {
...
private RecyclerAdapter<Customer> mAdapter;

void onCreate(...){
    mAdapter = new RecyclerAdapter(customerList, CustomerViewHolder.class);
}
...
}

RecyclerAdapter (Multi cell method)

@BindLayoutRes(R.layout.{name_of_your_layout1})
public class CustomerViewHolder1 extends RecyclerViewHolder<Customer> {
    CustomerViewHolder1(View view){
        super(view);
    }
    
    void onBind(Customer item){
        //todo implements
    }
}

@BindLayoutRes(R.layout.{name_of_your_layout2})
public class CustomerViewHolder2 extends RecyclerViewHolder<Customer> {
    CustomerViewHolder2(View view){
        super(view);
    }
    
    void onBind(Customer item){
        //todo implements
    }
}

//# Solution 1 : the object determines are own item view type 
public class Customer implements IViewType {
   public static final int TYPE_ON_LINE = 0; /*default*/
   public static final int TYPE_STORE = 1;
   public static final int TYPE_OTHER = 2;
   private int mType;
   
   @Override
    public int getItemViewType() {
        return mType;
    }
}

public class MyFragment extends Fragment {
    
    public void onCreateView(){
        private RecyclerAdapter<Customer> mAdapter;
        
        mAdapter = new RecyclerAdapter(customerList, CustomerViewHolder1.class/*type par default*/);
        mAdapter.putViewType(Customer.TYPE_STORE, CustomerViewHolder2.class, null /*callback*/);
        mAdapter.putViewType(Customer.TYPE_OTHER, CustomerViewHolder3.class, true /*add default callback*/);
        
        //# Solution 2 : We give the strategy of the IViewType to our adapt it
        mAdapter.setItemViewType(item -> {
            //todo stategy type of item
            return 0;
        });
        mRecyclerView.setAdapter(adapter);
    }

SectionDecorator (Recycler with LinearLayout)

precondition : create your RecyclerViewHolder Sample :

RecyclerAdapter<Customer> baseAdapter = new RecyclerAdapter<>(...);
RecyclerSectionedAdapter adapter = new RecyclerSectionedAdapter(SectionViewHolder.class, baseAdapter);

SectionDecorator (Recycler with GridLayout)

precondition : create your RecyclerViewHolder Sample :

mRecylerView.setLayoutManager(...);
RecyclerAdapter<Customer> baseAdapter = new RecyclerAdapter<>(...);
RecyclerSectionedAdapter<String, Customer> sectionAdapter = new RecyclerSectionedAdapter<>(SectionViewHolder.class, mRecylerView, baseAdapter);

sectionAdapter.addSection(0/*position*/, "Title Section 1");
Customer i = sectionAdapter.getItem(1 /*sectioned position*/);

mRecylerView.setAdapter(sectionAdapter);

ItemDecoration

mRecyclerView.addItemDecoration(new FooterDecoration(getContext(), this, R.layout.item_space_80));
