我写了一个库来处理android回收视图项目点击事件。你可以在https://github.com/ChathuraHettiarachchi/RecycleClick上找到完整的教程

RecycleClick.addTo(YOUR_RECYCLEVIEW).setOnItemClickListener(new RecycleClick.OnItemClickListener() {
            @Override
            public void onItemClicked(RecyclerView recyclerView, int position, View v) {
                // YOUR CODE
            }
        });

或处理项目长按即可使用

RecycleClick.addTo(YOUR_RECYCLEVIEW).setOnItemLongClickListener(new RecycleClick.OnItemLongClickListener() {
            @Override
            public boolean onItemLongClicked(RecyclerView recyclerView, int position, View v) {
                // YOUR CODE
                return true;
            }
        });

感谢@marmor，我更新了我的答案。

我认为在ViewHolder类构造函数中处理onClick()并通过OnItemClickListener接口将其传递给父类是一个很好的解决方案。

MyAdapter.java

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder>{

private LayoutInflater layoutInflater;
private List<MyObject> items;
private AdapterView.OnItemClickListener onItemClickListener;

public MyAdapter(Context context, AdapterView.OnItemClickListener onItemClickListener, List<MyObject> items) {
    layoutInflater = LayoutInflater.from(context);
    this.items = items;
    this.onItemClickListener = onItemClickListener;
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View view = layoutInflater.inflate(R.layout.my_row_layout, parent, false);
    return new ViewHolder(view);
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    MyObject item = items.get(position);
}

public MyObject getItem(int position) {
    return items.get(position);
}


class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
    private TextView title;
    private ImageView avatar;

    public ViewHolder(View itemView) {
        super(itemView);
        title = itemView.findViewById(R.id.title);
        avatar = itemView.findViewById(R.id.avatar);

        title.setOnClickListener(this);
        avatar.setOnClickListener(this);
        itemView.setOnClickListener(this);
    }

    @Override
    public void onClick(View view) {
        //passing the clicked position to the parent class
        onItemClickListener.onItemClick(null, view, getAdapterPosition(), view.getId());
    }
}
}

适配器在其他类中的使用:

MyFragment.java

public class MyFragment extends Fragment implements AdapterView.OnItemClickListener {

private RecyclerView recycleview;
private MyAdapter adapter;

    .
    .
    .

private void init(Context context) {
    //passing this fragment as OnItemClickListener to the adapter
    adapter = new MyAdapter(context, this, items);
    recycleview.setAdapter(adapter);
}

@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
    //you can get the clicked item from the adapter using its position
    MyObject item = adapter.getItem(position);

    //you can also find out which view was clicked
    switch (view.getId()) {
        case R.id.title:
            //title view was clicked
            break;
        case R.id.avatar:
            //avatar view was clicked
            break;
        default:
            //the whole row was clicked
    }
}

}

 main_recyclerview.addOnItemTouchListener(new RecyclerView.OnItemTouchListener() {
        @Override
        public boolean onInterceptTouchEvent(RecyclerView rv, MotionEvent e)
        {
            int position=rv.getChildAdapterPosition(rv.findChildViewUnder(e.getX(),e.getY()));

            switch (position)
            {
                case 0:
                {
                    wifi(position);
                    adapter2.notifyDataSetChanged();
                }
                break;

                case 1:
                {
                    sound(position);
                    adapter2.notifyDataSetChanged();
                }
                break;

                case 2:
                {
                    bluetooth(position);
                    adapter2.notifyDataSetChanged();
                }
                break;


            }
            return true;
        }

        @Override
        public void onTouchEvent(RecyclerView rv, MotionEvent e)
        {

        }

        @Override
        public void onRequestDisallowInterceptTouchEvent(boolean disallowIntercept) {

        }
    });

Recyclerview动画没有经过测试，其他正常。我认为它已经优化到最大。接口有其他用途，可以暂时忽略。

public abstract class BaseAdapterRV<VH extends BaseViewHolder> extends RecyclerView.Adapter<VH> implements AdapterInterface {
    public final String TAG = getClass().getSimpleName();

    protected final Activity mActivity;
    protected final LayoutInflater mInflater;
    protected ItemClickInterface<?, Integer> mListener;

    public BaseAdapterRV(Activity activity) {
        mActivity = activity;
        mInflater = LayoutInflater.from(mActivity);
    }

    @Override
    public final VH onCreateViewHolder(ViewGroup parent, int viewType) {
        return onCreateViewHolder(parent, viewType, mInflater);
    }

    @Override
    public final void onBindViewHolder(VH holder, int position) {
        holder.itemView.setTag(R.id.tag_view_click, position);
        //创建点击事件
        holder.itemView.setOnClickListener(mListener);
        holder.itemView.setOnLongClickListener(mListener);
        onBindVH(holder, position);
    }


    ///////////////////////////////////////////////////////////////////////////
    // 以下是增加的方法
    ///////////////////////////////////////////////////////////////////////////

    /**
     * 注意!涉及到notifyItemInserted刷新时立即获取position可能会不正确
     * 里面也有onItemLongClick
     */
    public void setOnItemClickListener(ItemClickInterface<?, Integer> listener) {
        mListener = listener;
        notifyDataSetChanged();
    }

    @NonNull
    protected abstract VH onCreateViewHolder(ViewGroup parent, int viewType, LayoutInflater inflater);

    protected abstract void onBindVH(VH holder, int position);

}

这是接口

/**
 * OnItemClickListener的接口
 * 见子类实现{@link OnItemClickListener}{@link OnItemItemClickListener}
 */
public interface ItemClickInterface<DATA1, DATA2> extends View.OnClickListener, View.OnLongClickListener {

    void onItemClick(DATA1 data1, DATA2 data2);

    boolean onItemLongClick(DATA1 data1, DATA2 data2);
}

这是一个抽象类

public abstract class OnItemClickListener<DATA> implements ItemClickInterface<View, DATA> {
    @Override
    public void onClick(View v) {
        onItemClick(v, (DATA) v.getTag(R.id.tag_view_click));
    }

    @Override
    public boolean onLongClick(View v) {
        return onItemLongClick(v, (DATA) v.getTag(R.id.tag_view_click));
    }

    @Override
    public boolean onItemLongClick(View view, DATA data) {
        return false;
    }
}

你只需要它

    mAdapter.setOnItemClickListener(new OnItemClickListener<Integer>() {
        @Override
        public void onItemClick(View view, Integer integer) {

        }

        @Override
        public boolean onItemLongClick(View view, Integer integer) {
            return true;
        }
    });

跟进MLProgrammer-CiM的优秀RxJava解决方案

消费/观察点击

Consumer<String> mClickConsumer = new Consumer<String>() {
        @Override
        public void accept(@NonNull String element) throws Exception {
            Toast.makeText(getApplicationContext(), element +" was clicked", Toast.LENGTH_LONG).show();
        }
    };

ReactiveAdapter rxAdapter = new ReactiveAdapter();
rxAdapter.getPositionClicks().subscribe(mClickConsumer);

RxJava 2.+

将原tl;dr修改为:

public Observable<String> getPositionClicks(){
    return onClickSubject;
}

PublishSubject#asObservable()被移除。只需要返回PublishSubject，它是一个可观察对象。

在这里，你可以处理多个点击看到下面的代码，这是非常有效的

    public class RVNewsAdapter extends RecyclerView.Adapter<RVNewsAdapter.FeedHolder> {

    private Context context;
    List<News> newsList;
    // Allows to remember the last item shown on screen
    private int lastPosition = -1;

    public RVNewsAdapter(List<News> newsList, Context context) {
        this.newsList = newsList;
        this.context = context;
    }

    public static class FeedHolder extends RecyclerView.ViewHolder implements OnClickListener {

        ImageView img_main;
        TextView tv_title;
        Button bt_facebook, bt_twitter, bt_share, bt_comment;


        public FeedHolder(View itemView) {
            super(itemView);

            img_main = (ImageView) itemView.findViewById(R.id.img_main);
            tv_title = (TextView) itemView.findViewById(R.id.tv_title);
            bt_facebook = (Button) itemView.findViewById(R.id.bt_facebook);
            bt_twitter = (Button) itemView.findViewById(R.id.bt_twitter);
            bt_share = (Button) itemView.findViewById(R.id.bt_share);
            bt_comment = (Button) itemView.findViewById(R.id.bt_comment);

            img_main.setOnClickListener(this);
            bt_facebook.setOnClickListener(this);
            bt_twitter.setOnClickListener(this);
            bt_comment.setOnClickListener(this);
            bt_share.setOnClickListener(this);

        }


        @Override
        public void onClick(View v) {

            if (v.getId() == bt_comment.getId()) {

                Toast.makeText(v.getContext(), "Comment  " , Toast.LENGTH_SHORT).show();

            } else if (v.getId() == bt_facebook.getId()) {

                Toast.makeText(v.getContext(), "Facebook  " , Toast.LENGTH_SHORT).show();

            } else if (v.getId() == bt_twitter.getId()) {

                Toast.makeText(v.getContext(), "Twitter  " , Toast.LENGTH_SHORT).show();

            } else if (v.getId() == bt_share.getId()) {

                Toast.makeText(v.getContext(), "share  " , Toast.LENGTH_SHORT).show();

            }
            else {
                Toast.makeText(v.getContext(), "ROW PRESSED = " + String.valueOf(getAdapterPosition()), Toast.LENGTH_SHORT).show();
            }
        }
    }

    @Override
    public void onAttachedToRecyclerView(RecyclerView recyclerView) {
        super.onAttachedToRecyclerView(recyclerView);
    }

    @Override
    public FeedHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = LayoutInflater.from(parent.getContext()).inflate(R.layout.feed_row, parent, false);
        FeedHolder feedHolder = new FeedHolder(view);

        return feedHolder;
    }

    @Override
    public void onBindViewHolder(FeedHolder holder, int position) {

        holder.tv_title.setText(newsList.get(position).getTitle());


        // Here you apply the animation when the view is bound
        setAnimation(holder.img_main, position);
    }

    @Override
    public int getItemCount() {
        return newsList.size();
    }


    /**
     * Here is the key method to apply the animation
     */
    private void setAnimation(View viewToAnimate, int position) {
        // If the bound view wasn't previously displayed on screen, it's animated
        if (position > lastPosition) {
            Animation animation = AnimationUtils.loadAnimation(context, android.R.anim.slide_in_left);
            viewToAnimate.startAnimation(animation);
            lastPosition = position;
        }
    }


}
