RecyclerView onClickListener [英] RecyclerView onClickListener

问题描述

因此，经过5个月的网络开发，我需要重新使用android，但我发现我的一些旧代码不再起作用.我有一个带有数据适配器的RecyclerView，但该项目的onClickListener没有响应.这是我的代码:

So after 5 months of webdevelopment I needed to get back into android but I noticed some of my old code isn't working anymore. I have a RecyclerView with a adapter for the data but the onClickListener for the items doesn't respond to anything. This is what my code looks like:

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

ProjectsActivity.java

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

显示该列表，单击不起作用，甚至不记录到控制台. 有人知道我在做什么错吗?我正在使用SDK v23作为编译SDK版本.我的最低SDK版本是v19.

The list gets showed, the click doesn't work, not even the log to the console. Does anybody know what I've been doing wrong? I'm using SDK v23 as the compile sdk version. My minimum SDK version is v19.

推荐答案

找到这样的视图后添加一个点击:

add a click after finding View like this:

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);
        }
