这个作品。

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

private final Context mContext;
private List<ServiceListModel> categoryList;
private View.OnClickListener onClickListener;

public ServiceListAdapter(Context mContext, List<ServiceListModel> categoryList, View.OnClickListener onClickListener) {
    this.categoryList = categoryList;
    this.mContext = mContext;
    this.onClickListener = onClickListener;
}

@Override
public ViewHolder onCreateViewHolder(final ViewGroup parent, final int viewType) {
    final LayoutInflater inflater = LayoutInflater.from(parent.getContext());
    final RowServiceListBinding binding = DataBindingUtil.inflate(inflater, R.layout.row_service_list, parent, false);
    return new ViewHolder(binding.getRoot(), binding);
}

@Override
public void onBindViewHolder(final ViewHolder holder, final int position) {
    holder.binding.rlService.setOnClickListener(onClickListener);
    holder.binding.rlService.setTag(position);
}

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

public class ViewHolder extends RecyclerView.ViewHolder {
    private final RowServiceListBinding binding;

    public ViewHolder(final View view, final RowServiceListBinding binding) {
        super(view);
        this.binding = binding;
    }

    @UiThread
    public void bind(final ServiceListModel mAddressModel) {
        //this.binding.setAddress(mAddressModel);
    }
}
}

在活动/片段中使用

ServiceListAdapter adapter = new ServiceListAdapter(context, serviceList, new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            switch (v.getId()) {
                case R.id.rlService:
                    int pos = (int) v.getTag();
                    serviceList.remove(position);
                    break;
            }
        }
    });

让我们看看如何在Jetpack / AndroidX中实现这一点

你需要像这样在viewmodel类中创建一个观察对象

private MutableLiveData<Integer> adapterItem = new MutableLiveData<>();

public MutableLiveData<Integer> getAdapterItem() {
    return adapterItem;
}

public void setAdapterItem(int adapterItem) {
    this.getAdapterItem().setValue(adapterItem);
}

然后在适配器类中，确保将viewmodel引用作为构造函数的参数传递，然后在vieholder上实现clicklistener

    public MyViewHolder(@NonNull View itemView) {
        super(itemView);
        if(itemView != null){
            itemView.setOnClickListener(v -> {
                int adapterPosition = getAdapterPosition();
                viewModel.setAdapterItem(adapterPosition);
            });

        };
    }

然后从活动课上观察变化

    viewModel.getAdapterItem().observe(this, position -> {
        Log.w(TAG, "clicked: " + ridesArray.get(position));
    });

以下是我所做的。这个解决方案同时支持onClick和onLongClick在两个RecyclerView项目和视图内的RecyclerView项目(内部视图)。

我在我选择的视图上标记viewHolder:

public RecyclerViewAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View itemView = LayoutInflater.from(parent.getContext()).inflate(R.layout.layout_item, null);
    ViewHolder viewHolder = new ViewHolder(itemView);

    itemView.setOnClickListener( this);
    itemView.setOnLongClickListener(this);
    viewHolder.imageIV.setOnClickListener(this);
    viewHolder.imageIV.setOnLongClickListener(this);

    viewHolder.imageIV.setTag(viewHolder);
    itemView.setTag(viewHolder);

    return viewHolder;
}

我使用holder.getPosition()在onClick()方法中检索位置(onLongClick类似):

public void onClick(View view) {
    ViewHolder holder = (ViewHolder) view.getTag();
    int position = holder.getPosition();

    if (view.getId() == holder.imageIV.getId()){
        Toast.makeText(context, "imageIV onClick at" + position, Toast.LENGTH_SHORT).show();
    } else {
        Toast.makeText(context, "RecyclerView Item onClick at " + position, Toast.LENGTH_SHORT).show();
    }
}

带有getChildPosition的变体也可以工作。请注意，对于内部视图，在onClick()中使用:

int position = recyclerView.getChildPosition((View)view.getParent());

在我看来，这个解决方案的优点是，当一个人点击图像，只有onclick()图像侦听器被调用，而当我结合Jacob的解决方案为一个RecyclerView项目视图和我的解决方案为内部视图的RecyclerView项目视图onclick()也被调用(当点击图像)。

试试这个，很简单。这对我很管用。顺便说一句，我发现setOnClickListener对RecyclerView不生效。

recycler.setOnTouchListener(new OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        if (event.getAction() == MotionEvent.ACTION_UP) {
            // anything todo
        }

        return true;
    }
});

你可以很容易地在ViewHolder类中定义setOnClickListener，如下所示:

public class ViewHolder extends RecyclerView.ViewHolder {
    TextView product_name;

    ViewHolder(View itemView) {
        super(itemView);
        product_name = (TextView) itemView.findViewById(R.id.product_name);
        itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                int itemPosition = getLayoutPosition();
                Toast.makeText(getApplicationContext(), itemPosition + ":" + String.valueOf(product_name.getText()), Toast.LENGTH_SHORT).show();
            }
        });
    }
}

对我来说，这是最好的方法:

class YourRecyclerAdapter extends RecyclerView.Adapter<ContactViewHolder> implements View.OnClickListener { 
  ...
  @Override
  public void onClick(View view) {
        int itemPosition = vRecycle.getChildPosition(view);
        //And use itemPosition to get the item from your collection. This way you dont restrain the ViewHolder with a OnClick callback
    }
  ...
}
