RecyclerView onClickListener

Question

因此，经过 5 个月的网络开发后，我需要回到 Android，但我注意到我的一些旧代码不再工作了。我有一个带有数据适配器的 RecyclerView，但项目的 onClickListener 没有响应任何内容。这是我的代码的样子：

 public class ProjectAdapter extends RecyclerView.Adapter<ProjectAdapter.ViewHolder> {
    private List<Project> itemsData;

    OnItemClickListener mItemClickListener;

    public ProjectAdapter(List<Project> itemsData) {
        this.itemsData = itemsData;
    }

    // Create new views (invoked by the layout manager)
    @Override
    public ViewHolder onCreateViewHolder(ViewGroup parent,
                                                   int viewType) {
        // create a new views
        View itemLayoutView = LayoutInflater.from(parent.getContext())
                .inflate(R.layout.item_layout, parent, false);

        // create ViewHolder
        ViewHolder vh = new ViewHolder(itemLayoutView);
        return vh;
    }

    // Replace the contents of a view (invoked by the layout manager)
    @Override
    public void onBindViewHolder(ViewHolder viewHolder, int position) {

        viewHolder.txtViewId.setText(String.valueOf(itemsData.get(position).getId()));
        viewHolder.txtViewName.setText(itemsData.get(position).getName());

    }

    // inner class to hold a reference to each item of RecyclerView
    public class ViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener{

        public TextView txtViewName, txtViewId;

        public ViewHolder(View itemLayoutView) {
            super(itemLayoutView);
            txtViewName = (TextView) itemLayoutView.findViewById(R.id.item_name);
            txtViewId = (TextView) itemLayoutView.findViewById(R.id.item_id);

        }

        @Override
        public void onClick(View v) {
            System.out.println("onClick");
            TextView tv = (TextView) v.findViewById(R.id.item_name);
            String id = tv.getText().toString();
            mItemClickListener.onItemClick(v, getAdapterPosition(), id); //OnItemClickListener mItemClickListener;
        }
    }

    public interface OnItemClickListener {
        public void onItemClick(View view, int position, String id);
    }

    public void SetOnItemClickListener(final OnItemClickListener mItemClickListener) {
        this.mItemClickListener = mItemClickListener;
    }

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

项目活动.java

 projectAdapter.SetOnItemClickListener(new ProjectAdapter.OnItemClickListener() {
    @Override
    public void onItemClick(View v, int position, String id) {
        System.out.println("onItemClick" + id);
        ActionActivity(id);
    }
});

显示列表，点击不起作用，甚至没有日志到控制台。有人知道我做错了什么吗？我使用 SDK v23 作为编译 sdk 版本。我的最低 SDK 版本是 v19。

找到View后添加点击是这样的：

 public ViewHolder(View itemLayoutView) {
            super(itemLayoutView);
            txtViewName = (TextView) itemLayoutView.findViewById(R.id.item_name);
            txtViewId = (TextView) itemLayoutView.findViewById(R.id.item_id);
           // here
           itemLayoutView.setOnClickListener(this);
        }

将项目点击侦听器设置为回收站视图行：

 public ViewHolder(View itemLayoutView) {
        super(itemLayoutView);
        itemLayoutView.setOnClickListener(new OnClickListener() {
              @Override
              public void onClick(View v) {
                   TextView tv = (TextView) v.findViewById(R.id.item_name);
                   String id = tv.getText().toString();
                   mItemClickListener.onItemClick(getLayoutPosition(), v, id);
              }
        });
        txtViewName = (TextView) itemLayoutView.findViewById(R.id.item_name);
        txtViewId = (TextView) itemLayoutView.findViewById(R.id.item_id);

    }
