如何修复RecyclerView OnClick缺口显示错误？

Question

我正在设置一个包含多个ImageButtons的RecyclerView，每个ImageButton都有一个OnClick动作（启动一个Activity）我的问题是，OnClick动作不能用于ImageButtons，而是在每个ImageButton之间的一个小空间（如果我想点击在第一个按钮上，我必须点击第一个和第二个按钮之间的空格）

我试过改变图像大小

RecyclerView适配器：

   public class RecyclerViewAdapter extends RecyclerView.Adapter<RecyclerViewAdapter.ViewHolder>
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        View view = mInflater.inflate(R.layout.recycler_view, parent, false);
        return new ViewHolder(view);
    }

    // binds the data to the ImageButton in each row
    @Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        int currentCategory = mData.get(position).getImage();
        holder.categoriesButton.setImageResource(currentCategory);
    }

    // stores and recycles views as they are scrolled off screen
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {
        ImageButton categoriesButton;

        ViewHolder(View itemView) {
            super(itemView);
            categoriesButton = itemView.findViewById(R.id.image_Button_Category_id);
            itemView.setOnClickListener(this);
        }

        @Override
        public void onClick(View view) {
            if (mClickListener != null) mClickListener.onItemClick(view, getAdapterPosition());
        }
    }

    // convenience method for getting data at click position
    public int getItem(int id) {
        return mData.get(id).getImage();
    }

    // allows clicks events to be caught
    public void setClickListener(ItemClickListener itemClickListener) {
        this.mClickListener = itemClickListener;
    }

    // parent activity will implement this method to respond to click events
    public interface ItemClickListener {
        void onItemClick(View view, int position);
    }

RecyclerLayout：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android="http://schemas.android.com/apk/res/android" 
android:layout_width="match_parent"
android:layout_height="match_parent">
  <ImageButton
    android:id="@+id/image_Button_Category_id"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />

这是我的MainActivity：

  private void setRecyclerViewOn(ArrayList<Category> list) {
    RecyclerView recyclerView = findViewById(R.id.recyclerView_id);
    recyclerView.setLayoutManager(new LinearLayoutManager(this));
    adapter = new RecyclerViewAdapter(this, list);
    adapter.setClickListener(this);
    recyclerView.setAdapter(adapter);
}

@Override
public void onItemClick(View view, int position) {
    Toast.makeText(this, "You clicked " + adapter.getItem(position) + " on row number " + position, Toast.LENGTH_SHORT).show();
    startActivity(createIntent(position));
}

预期结果：单击侦听器必须位于每个ImageButton上

尝试在onBindView（）上添加click侦听器

@Override
    public void onBindViewHolder(ViewHolder holder, int position) {
        int currentCategory = mData.get(position).getImage();
        holder.categoriesButton.setImageResource(currentCategory);
        holder.vategoriesButton.setOnClickListener(...)
    }
