RecyclerView onItemClick 侦听器 [英] RecyclerView onItemClick Listener

问题描述

如何实现 RecyclerView onItemClick 监听器，就像我们使用 ListView 一样，这是我使用 ListView 的旧适配器类:

How to implement RecyclerView onItemClick listener as we do with ListView, this is my old Adapter class using ListView:

public class GenreAdapter extends BaseAdapter {

....

@Override
public View getView(final int position, View convertView, ViewGroup parent) {
    // convert view = design
    View v = convertView;
    if (v == null) {
        holder = new ViewHolder();
        v = vi.inflate(Resource, null);
        holder.textTitle = (TextView) v.findViewById(R.id.textTitle);
        v.setTag(holder);
    } else {
        holder = (ViewHolder) v.getTag();
    }

    holder.textTitle.setText(genreArrayList.get(position).getTitle());

    v.setOnClickListener(new OnClickListener() {

       @Override
       public void onClick(View v) {                          

           Bundle bundle = new Bundle();
           bundle.putSerializable("data", genreArrayList);
           bundle.putInt("current", position);             

           Intent intent = new Intent(context, MovieActivity.class);
           intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
           intent.putExtras(bundle);
           context.startActivity(intent);

        }
    });

    return v;
}

static class ViewHolder {
    public TextView textTitle;
}

MainFragment.java:-

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        view = inflater.inflate(R.layout.fragment_main, container, false);

        /* Initialize recycler view */
        mRecyclerView = (RecyclerView) view.findViewById(R.id.recycler_view);
        mRecyclerView.setLayoutManager(new LinearLayoutManager(getActivity()));

        mRecyclerView.addItemDecoration(new DividerItemDecoration(getActivity(), DividerItemDecoration.VERTICAL_LIST));

        list = new ArrayList<MainPoho>();
        adapter = new MainAdapter(getActivity(), list);
        mRecyclerView.setAdapter(adapter);

        .......

}

这是我使用 RecyclerView 的新 Adapter 类:

And here is my new Adapter class using RecyclerView :

public class MyRecyclerAdapter extends RecyclerView.Adapter<FeedListRowHolder> {

    private List<FeedItem> feedItemList;
    private Context mContext;

    public MyRecyclerAdapter(Context context, List<FeedItem> feedItemList) {
        this.feedItemList = feedItemList;
        this.mContext = context;
    }

    @Override
    public FeedListRowHolder onCreateViewHolder(ViewGroup viewGroup, int i) {
        View v = LayoutInflater.from(viewGroup.getContext()).inflate(R.layout.list_row, null);
        FeedListRowHolder mh = new FeedListRowHolder(v);
        return mh;
    }

    @Override
    public void onBindViewHolder(FeedListRowHolder feedListRowHolder, int i) {
        FeedItem feedItem = feedItemList.get(i);        
        feedListRowHolder.title.setText(Html.fromHtml(feedItem.getTitle()));
    }

    @Override
    public int getItemCount() {
        if(feedItemList !=null){
            return feedItemList.size();
          } else {
            return 0;
          }
    }

<小时>

public class FeedListRowHolder extends RecyclerView.ViewHolder {
    protected TextView title;

    public FeedListRowHolder(View view) {
        super(view);
        this.title = (TextView) view.findViewById(R.id.title);
    }

FeedItem.java:-

public class FeedItem {
    private String title;

    public String getTitle() {
        return title;
    }

    public void setTitle(String title) {
        this.title = title;
    }

}

推荐答案

首先在你的 viewHolder 中存储整个视图:

first store whole view in your viewHolder:

  public class FeedListRowHolder extends RecyclerView.ViewHolder {
     protected TextView title;
     protected View mRootView;

    public FeedListRowHolder(View view) {
        super(view);
        this.title = (TextView) view.findViewById(R.id.title);
        mRootView = view;
    }

然后在 onBindViewHolder 设置点击监听器:

then set click listener at onBindViewHolder:

@Override
public void onBindViewHolder(FeedListRowHolder feedListRowHolder, int i) {
    FeedItem feedItem = feedItemList.get(i);        
    feedListRowHolder.title.setText(Html.fromHtml(feedItem.getTitle()));
    feedListRowHolder.mRootView.setOnClickListener(new OnClickListener(){

        @Override
        public void onClick(View v) {

        }
   });
}
