不幸的是，RecyclerView缺少ListView内置的几个功能。 例如，添加OnItemClickListener的能力，当一个项目被单击时触发。 RecyclerView允许你在适配器中设置一个OnClickListener，但是传递那个点击 从你的调用代码，到适配器，再到ViewHolder，监听器是复杂的 要捕捉一个简单的项目单击。

public class ItemClickSupport {
private final RecyclerView mRecyclerView;
private OnItemClickListener mOnItemClickListener;
private OnItemLongClickListener mOnItemLongClickListener;
private View.OnClickListener mOnClickListener = new View.OnClickListener() {
    @Override
    public void onClick(View v) {
        if (mOnItemClickListener != null) {
            RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
            mOnItemClickListener.onItemClicked(mRecyclerView, holder.getAdapterPosition(), v);
        }
    }
};
private View.OnLongClickListener mOnLongClickListener = new View.OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        if (mOnItemLongClickListener != null) {
            RecyclerView.ViewHolder holder = mRecyclerView.getChildViewHolder(v);
            return mOnItemLongClickListener.onItemLongClicked(mRecyclerView, holder.getAdapterPosition(), v);
        }
        return false;
    }
};
private RecyclerView.OnChildAttachStateChangeListener mAttachListener
        = new RecyclerView.OnChildAttachStateChangeListener() {
    @Override
    public void onChildViewAttachedToWindow(View view) {
        if (mOnItemClickListener != null) {
            view.setOnClickListener(mOnClickListener);
        }
        if (mOnItemLongClickListener != null) {
            view.setOnLongClickListener(mOnLongClickListener);
        }
    }

    @Override
    public void onChildViewDetachedFromWindow(View view) {

    }
};

private ItemClickSupport(RecyclerView recyclerView) {
    mRecyclerView = recyclerView;
    mRecyclerView.setTag(R.id.item_click_support, this);
    mRecyclerView.addOnChildAttachStateChangeListener(mAttachListener);
}

public static ItemClickSupport addTo(RecyclerView view) {
    ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
    if (support == null) {
        support = new ItemClickSupport(view);
    }
    return support;
}

public static ItemClickSupport removeFrom(RecyclerView view) {
    ItemClickSupport support = (ItemClickSupport) view.getTag(R.id.item_click_support);
    if (support != null) {
        support.detach(view);
    }
    return support;
}

public ItemClickSupport setOnItemClickListener(OnItemClickListener listener) {
    mOnItemClickListener = listener;
    return this;
}

public ItemClickSupport setOnItemLongClickListener(OnItemLongClickListener listener) {
    mOnItemLongClickListener = listener;
    return this;
}

private void detach(RecyclerView view) {
    view.removeOnChildAttachStateChangeListener(mAttachListener);
    view.setTag(R.id.item_click_support, null);
}

public interface OnItemClickListener {

    void onItemClicked(RecyclerView recyclerView, int position, View v);
}

public interface OnItemLongClickListener {

    boolean onItemLongClicked(RecyclerView recyclerView, int position, View v);
}
}

您还需要定义R.id。使用ids.xml:

 <?xml version="1.0" encoding="utf-8"?>
 <resources>
  <item name="item_click_support" type="id" />
 </resources>

结果代码点击侦听器现在看起来像这样:

ItemClickSupport.addTo(mRecyclerView).setOnItemClickListener(new ItemClickSupport.OnItemClickListener() {
@Override
public void onItemClicked(RecyclerView recyclerView, int position, View v) {
    // do it
}
});

关于recyclerview点击的简要说明，请看看这个littlerobots_blog

根据Yigit Boyar的说法，在RecyclerView上注册点击的最好方法是在ViewHolder的创建中定义点击，而不是仅仅为onBindViewHolder绑定的每个项目创建一个新的onClickListener

例子:

override fun onCreateViewHolder(parent: ViewGroup, viewType: Int): BaseViewHolder<*> {
   val itemBinding = LayoutInflater.from(context).inflate(R.layout.my_layout, parent, false)

   val vh = MainViewHolder (itemBinding)
   vh.itemView.setOnClickListener {
       val pos = vh.adapterPosition
       if(pos != NO_POSITION){
           itemClickLister.onCocktailClick(myList[pos],pos)
       }
   }

   return vh
}

这就是我最后需要的东西，以防有人发现它有用:

public static class ViewHolder extends RecyclerView.ViewHolder {

    public ViewHolder(View item) {

        super(item);
        item.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                Log.d("RecyclerView", "onClick：" + getAdapterPosition());
            }
        });

    }
}

这对我来说很管用。将OnClickListener附加到onBindView。我真的不知道这是否会影响性能，但它似乎用很少的代码就能很好地工作。

public void onBindViewHolder(ViewHolder holder, final int position) {
    holder.view.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Toast.makeText(context, "Recycle Click" + position, Toast.LENGTH_SHORT).show();
            }
    });
}

将类标记为抽象并实现OnClick方法

public abstract class MainGridAdapter extends
    RecyclerView.Adapter<MainGridAdapter.ViewHolder> {
private List<MainListItem> mDataset;

// Provide a reference to the views for each data item
// Complex data items may need more than one view per item, and
// you provide access to all the views for a data item in a view holder
public class ViewHolder extends RecyclerView.ViewHolder {
    // each data item is just a string in this case
    public TextView txtHeader;
    public TextView txtFooter;

    public ViewHolder(View v) {
        super(v);
        txtHeader = (TextView) v.findViewById(R.id.firstLine);
        txtFooter = (TextView) v.findViewById(R.id.secondLine);
    }
}

public void add(int position, MainListItem item) {
    mDataset.add(position, item);
    notifyItemInserted(position);
}

public void remove(MainListItem item) {
    int position = mDataset.indexOf(item);
    mDataset.remove(position);
    notifyItemRemoved(position);
}

// Provide a suitable constructor (depends on the kind of dataset)
public MainGridAdapter(List<MainListItem> myDataset) {
    mDataset = myDataset;
}

// Create new views (invoked by the layout manager)
@Override
public MainGridAdapter.ViewHolder onCreateViewHolder(ViewGroup parent,
        int viewType) {
    // create a new view
    View v = LayoutInflater.from(parent.getContext()).inflate(
            R.layout.list_item_grid_line, parent, false);
    // set the view's size, margins, paddings and layout parameters
    ViewHolder vh = new ViewHolder(v);
    return vh;
}

// Replace the contents of a view (invoked by the layout manager)
@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
    // - get element from your dataset at this position
    // - replace the contents of the view with that element     
    OnClickListener clickListener = new OnClickListener() {
        @Override
        public void onClick(View v) {
            onItemClicked(position);
        }
    };
    holder.itemView.setOnClickListener(clickListener);
    holder.txtHeader.setOnClickListener(clickListener);
    holder.txtFooter.setOnClickListener(clickListener);
    final MainListItem item = mDataset.get(position);
    holder.txtHeader.setText(item.getTitle());
    if (TextUtils.isEmpty(item.getDescription())) {
        holder.txtFooter.setVisibility(View.GONE);
    } else {
        holder.txtFooter.setVisibility(View.VISIBLE);
        holder.txtFooter.setText(item.getDescription());
    }
}

// Return the size of your dataset (invoked by the layout manager)
@Override
public int getItemCount() {
    return mDataset.size();
}

public abstract void onItemClicked(int position);

}

在绑定事件中实现单击处理程序，使其只有一个事件实现

执行此:

mAdapter = new MainGridAdapter(listItems) {         
    @Override
    public void onItemClicked(int position) {
        showToast("Item Clicked: " + position, ToastPlus.STYLE_INFO);
    }
};

同样可以做长时间点击

你可以实现View。OnClickListener到你的ViewHolder类

public static class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        
    public Item item
    @InjectView(R.id.tv_title) 
    public TextView tvTitle;
    @InjectView(R.id.rl_row) 
    public RelativeLayout rlRow;

    public ViewHolder(View v) {
        super(v);
        ButterKnife.inject(this, v);
        v.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        Log.e("item title",item.getTitle());
    }
}

和onBindViewHolder设置你的视图持有人的项目:

public void onBindViewHolder(ViewHolder holder, int position) {
    holder.tvTitle.setText(objects.get(position).getTitle());
    holder.item = objects.get(position);
}
