如何解决单击水平 RecyclerView 中的项目的问题？

Question

我有一个横向回收视图。有一些按钮。我将在下面提供我的代码。所以问题是当我点击一个按钮时，没有发生任何事情。它只是认为我没有点击它。我有另一个回收站视图，但垂直视图和代码非常相似，但第二个视图有效。我一直在努力寻找一个错误。我真的希望你能帮助我。谢谢。

我的主要是：

  adapter1 = new RecyclerViewAdapterContinentsList(this, idList,continentList);
            recyclerViewForContinents.setAdapter(adapter1);
            adapter1.setClickListener(new RecyclerViewAdapterContinentsList.ItemClickListener() {
                @Override
                public void onItemClick(View view, int position) {
                    Toast.makeText(getApplicationContext(),"name",Toast.LENGTH_SHORT).show();
                    
                }
            });

recyclerView class:

public class RecyclerViewAdapterContinentsList extends RecyclerView.Adapter<RecyclerViewAdapterContinentsList.ViewHolder>{
    private List<String> mId;
    private List<String> mName;
    private LayoutInflater mInflater;
    private ItemClickListener mClickListener;
    Context context;

    RecyclerViewAdapterContinentsList(Context context, List<String> id, List<String> name) {
        this.mInflater = LayoutInflater.from(context);
        this.mId = id;
        this.mName = name;
        this.context = context;
    }

    // inflates the row layout from xml when needed
    @Override
    public ViewHolder onCreateViewHolder (ViewGroup parent, int viewType) {
        View view = mInflater.inflate(R.layout.activity_recycler_view_adapter_countinent_list, parent, false);
        return new ViewHolder(view);
    }

    // binds the data to the TextView in each row
    @Override
    public void onBindViewHolder(ViewHolder holder,final int position) {
        String id = mId.get(position);
        String name = mName.get(position);
        holder.continentBtn.setText(name);
    }

    // total number of rows
    @Override
    public int getItemCount() {
        return mName.size();
    }


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

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

        @Override
        public void onClick(View view) {
            if (mClickListener != null) {
                Toast.makeText(context,"name",Toast.LENGTH_SHORT).show();
                mClickListener.onItemClick(view, getAdapterPosition());}
        }
    }

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

    void setClickListener(RecyclerViewAdapterContinentsList.ItemClickListener itemClickListener) {
        Toast.makeText(context,"name",Toast.LENGTH_SHORT).show();
        this.mClickListener = itemClickListener;
    }

    public interface ItemClickListener {
        void onItemClick(View view, int position);
    }
}

Answer 1

更改您的 ViewHolder 代码以将 OnClickListener 附加到按钮而不是 itemView。

ViewHolder(View itemView) 
{
    super(itemView);
    continentBtn = itemView.findViewById(R.id.continentBtn);
    continentBtn.setOnClickListener(this);  // <-- button not itemView
}

在您的 ViewHolder 中，itemView 是您布局的根视图组 R.layout.activity_recycler_view_adapter_countinent_list，RecyclerView 可以使用 setOnItemClickListener.

监听整行的点击事件

Answer 2

很简单，

首先你在你的按钮视图中给出 id 比在你的适配器中 onBindViewHolder

在视图中设置监听器并在监听器中执行任何事件。

 @Override
    public void onBindViewHolder(@NonNull final recycler_item_ads.ViewHolder holder, final int position) {
        holder.installnow.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {

                   //here print toast
                } 
              
            }
        });

holfer.install 现在是我在布局文件中的按钮
