RecyclerView onClickListener

Question

因此,经过5个月的web开发,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.这就是我的代码:

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();
    }
}

ProjectsActivity.java

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

列表显示,单击不起作用,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之后添加一个点击:

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);
        }
