Android L中RecolyerView的挑战

Question

我已经使用recyclerview玩了一段时间。是否有任何简单的方法将onclicklistener放入RecyclerView中的项目？我尝试在viewholder中实现它。onClick事件从未被触发。

并且我使用NotifyItemInserted(position)向RecycerView中添加新值。UI不会自动刷新。需要上下拉来刷新。但是当我调用NotifyDataSetChanged(..)时，它就可以了。

谢谢你的建议。

这是我测试的第一个Android L组件，我正在那里堆放。

下面是我的适配器类：

public class AdapterRecyclerView extends RecyclerView.Adapter<AdapterRecyclerView.MyViewHolder> {

private List<String> arrExperiences;

//Provide a reference to the type of views that you are using - Custom ViewHolder
public class MyViewHolder extends RecyclerView.ViewHolder {

    public TextView tvExperienceTitle;
    public TextView tvExperienceDesc;

    public MyViewHolder(RelativeLayout itemView) {
        super(itemView);
        tvExperienceTitle = (TextView) itemView.findViewById(R.id.tv_experience_title);
        tvExperienceDesc = (TextView) itemView.findViewById(R.id.tv_experience_desc);
    }

}

//Provide a suitable constructor : depending on the kind of dataset.
public AdapterRecyclerView(List<String> arrExperiences){
    this.arrExperiences = arrExperiences;
}

//Create new view : invoke by a Layout Manager
@Override
public AdapterRecyclerView.MyViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    RelativeLayout view = (RelativeLayout) LayoutInflater.from(parent.getContext()).inflate(R.layout.view_item_recycler, parent, false);
    MyViewHolder myViewHolder = new MyViewHolder(view);
    return myViewHolder;
}

@Override
public void onBindViewHolder(AdapterRecyclerView.MyViewHolder viewHolder, int position) {
    //get element from your dataset at this position.
    //replace the content of the view with this element.
    viewHolder.tvExperienceTitle.setText(arrExperiences.get(position));
}

@Override
public int getItemCount() {
    return arrExperiences.size();
}

public void addExperience(String experience, int position){
    arrExperiences.add(position, experience);
    notifyItemInserted(position);
    //notifyDataSetChanged();
}

public void removeExperience(){
    int index = (int) (Math.random() * arrExperiences.size());
    arrExperiences.remove(index);
    notifyItemRemoved(index);
    //notifyDataSetChanged();
}
}

只需在适配器中添加以下内容：

@Override
public void onBindViewHolder(AdapterRecyclerView.MyViewHolder viewHolder, int position) {
    yourItems.setOnClickListener(new OnClickListener() {
       @Override
       public void onClick(View v) {
          //do your stuff
       }
   });
}
