RecyclerView.Adapter

笔记,下次找的时候方便一些.

import android.view.View;

import android.view.ViewGroup;

import android.widget.TextView;

import androidx.recyclerview.widget.RecyclerView;

import java.util.List;

public class NameAdapterextends RecyclerView.Adapter {

private ListmNames;

    public NameAdapter(List names) {

this.mNames = names;

    }

@Override

    public NameAdapter.HolderonCreateViewHolder(ViewGroup parent, int viewType) {

View view = View.inflate(parent.getContext(), R.layout.item, null);

        Holder holder =new Holder(view);

        return holder;

    }

@Override

    public void onBindViewHolder(NameAdapter.Holder holder, int position) {

holder.text.setText(mNames.get(position));

        holder.itemView.setTag(position);

    }

@Override

    public int getItemCount() {

return mNames.size();

    }

public class Holderextends RecyclerView.ViewHolder {

private final TextViewtext;

        public Holder(View itemView) {

super(itemView);

            text = itemView.findViewById(R.id.text_name);

        }

}

}
