之前对ListView的BaseAdapter进行过封装，只需重写一个getView方法；

现在慢慢的RecyclerView成为主流，下面是RecyclerView.Adapter的封装；

BaseRecyclerViewHolder类：

public class BaseRecyclerHolder extends RecyclerView.ViewHolder {    private SparseArrayCompat
    
      mViews;    public BaseRecyclerHolder(View itemView) {        super(itemView);        mViews = new SparseArrayCompat<>();    }    public 
     
       V getView(@IdRes int res){        View v = mViews.get(res);        if (v == null){            v = itemView.findViewById(res);            mViews.put(res,v);        }        return (V)v;    }}
     
    

BaseRecyclerViewAdapter类：

public abstract class BaseRecyclerAdapter
    
      extends RecyclerView.Adapter
     
       {    public Context context;    public int layoutRes;    public List
      
        items;    public BaseRecyclerAdapter(Context context,@LayoutRes int layoutRes){      this.context = context;      this.layoutRes = layoutRes;      items = new ArrayList
       
        ();    }    public BaseRecyclerAdapter(Context context,@LayoutRes int layoutResId, @Nullable List
        
          data) {        this.context = context;        this.items = data == null ? new ArrayList
         
          () : data; if (layoutResId != 0) { this.layoutRes = layoutResId; } } @Override public BaseRecyclerHolder onCreateViewHolder(ViewGroup parent, int viewType) { return new BaseRecyclerHolder(LayoutInflater.from(context).inflate(layoutRes,null)); } @Override public void onBindViewHolder(BaseRecyclerHolder holder, int position) { convert(holder,position); } @Override public int getItemCount() { return items.size(); } public void setData(List
          
            items) { this.items = items == null ? new ArrayList
           
            () : items; notifyDataSetChanged(); } public void addData(@IntRange(from = 0) int position, @NonNull T data) { items.add(position, data); notifyItemInserted(position); compatibilityDataSizeChanged(1); } public void addData( @NonNull T data) { items.add(data); notifyItemInserted(items.size()); } public void remove(int position) { items.remove(position); int internalPosition = position; notifyItemRemoved(internalPosition); notifyItemRangeChanged(internalPosition, items.size() - internalPosition); } private void compatibilityDataSizeChanged(int size) { final int dataSize = items == null ? 0 : items.size(); if (dataSize == size) { notifyDataSetChanged(); } } /** * 需要重写的方法 * @param holder * @param position */ public abstract void convert(BaseRecyclerHolder holder, int position);}
           
          
         
        
       
      
     
    

如何使用：MainActivity类：

public class MainActivity extends AppCompatActivity {    private final String TAG = this.getClass().getSimpleName();    private List
    
      d = Arrays.asList(            "A","B","C","D","E","F","G"            ,"H","I","J","K","L","M","N"            ,"O","P","Q","R","S","T"            ,"U","V","W","X","Y","Z");    private RecyclerView rv ;    private BaseRecyclerAdapter ap;    private List
     
       datas;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        initData();//        ap = new BaseRecyclerAdapter
      
       (MainActivity.this, R.layout.item_rv){//      还可以这样用//            @Override//            public void convert(BaseRecyclerHolder holder, int position) {////            }//        };        rv = findViewById(R.id.rv);        rv.setLayoutManager(new GridLayoutManager(this,3));        ap = new Ap(this,R.layout.item_rv);        rv.setAdapter(ap);        ap.setData(datas);    }    private void initData() {        datas = new ArrayList<>();        for (int i = 0; i < d.size(); i++) {            datas.add(d.get(i));        }    }    class Ap extends BaseRecyclerAdapter
       
        {        public Ap(Context c, int layoutRes) {            super(c, layoutRes);        }        @Override        public void convert(BaseRecyclerHolder holder, final int position) {            //链式调用              holder.setText(R.id.tv,items.get(position))                    .setOnClickListener(R.id.tv, new View.OnClickListener() {                        @Override                        public void onClick(View view) {                            ap.remove(position);                        }                    });        }    }}
       
      
     
    

其实就只有这一个是你关注的，需要实现的Adapter：

class Ap extends BaseRecyclerAdapter
    
     {    public Ap(Context c, int layoutRes) {        super(c, layoutRes);    }    @Override    public void convert(BaseRecyclerHolder holder, final int position) {        //链式调用          holder.setText(R.id.tv,items.get(position))                .setOnClickListener(R.id.tv, new View.OnClickListener() {                    @Override                    public void onClick(View view) {                        ap.remove(position);                    }                });    }}
    

是不是超简单：

这个是Demo，里面封装的更加全面；
