AdapterDelegate

An base adapter of your Recycle.Adapter

(1) you need to declare your own different types of adapterDelegate, let us defined two type of adapterDelegate ,every of them need extands BaseAdapterDelegate, just like blow code of that :

public class DogAdapterDelegate extends BaseAdapterDelegate<T> {
        /**
         * ..
         */
    @Override
    public boolean isForViewType(@NonNull T items, int position) {
        /**
         * please instand of your own data type, like DogBean, CatBean , String , int,.. ig
         */
        return items instanceof Dog;
    }
    @NonNull
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent) {
        return new DogViewHolder(inflater.inflate(R.layout.item_dog, parent, false));
    }
    @Override
    public void protected void onBindViewHolder(@NonNull T items, int position, @NonNull RecyclerView.ViewHolder viewHolder) {
        DogViewHolder vh = (DogViewHolder) holder;      
    }
}

then declare the other adapterDelegate

public class CatAdapterDelegate extends BaseAdapterDelegate<T> {
        /**
         * ..
         */
  @Override protected boolean isForViewType(@NonNull T items, int position) {
       /**
         * please instand of your own data type, like DogBean, CatBean , String , int,.. ig
         */
    return items instanceof Cat;
  }
  @NonNull @Override public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent) {
    return new CatViewHolder(inflater.inflate(R.layout.item_cat, parent, false));
  }
  @Override     
  public void protected void onBindViewHolder(@NonNull T items, int position, @NonNull RecyclerView.ViewHolder viewHolder) {
    CatViewHolder vh = (CatViewHolder) holder;
  }

in this adapter you just implement some features of your originally logic.

please notice that ,the funtion 'isForViewType' ,you should be verify the type of data

you can observer in the above example 'isForViewType' .

(2) declare core classes of 'MainAdapterDelegate'

you need to declare an adapterDelegate sense of 'Main' (or 'Major', just sense of..), it used to added your different of your own adapterDelegate before , for instance :

public class MainAdapterDelegate extends RecyclerView.Adapter {
    private List<? extends Object> objectDatas;
   
    private AdapterDelegatesManager adapterDelegatesManager;
    public CashbackMainAdapterDelegate(Context context) { 
        objectDatas = new ArrayList<>();
       /**
         * in here..
         */
        adapterDelegatesManager = new AdapterDelegatesManager();
        adapterDelegatesManager.addDelegate(new CatAdapterDelegate(mContext));
        adapterDelegatesManager.addDelegate(new DogAdapterDelegate(mContext));
    }
    @Override
    public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return adapterDelegatesManager.onCreateViewHolder(parent, viewType);
    }

    @Override
    public void onBindViewHolder(RecyclerView.ViewHolder holder, int position) {
        adapterDelegatesManager.onBindViewHolder(objectDatas.get(position), position, holder);
    }
    @Override
    public int getItemCount() {
        return objectDatas == null ? 0 : objectDatas.size();
    }
    @Override
    public int getItemViewType(int position) {
        return adapterDelegatesManager.getItemViewType(objectDatas.get(position), position);
    }
}

In this step, you need to defined 'MainAdapterDelegate' and add those different types of adapterDelegate before

（3）last step is that you need to defined MainAdapterdelegate

recycle.setAdapter(new MainAdapterDelegate(this))

finally , you can use it !

any question , you can email with me

thans for you time to read !
