我已经使用notifyItemInserted(position)将新值添加到RecyclerView中.用户界面没有自动刷新.需要上下刷新.但是当我调用notifyDatasetChanged(..)时,没关系.

我已经将DefaultItemAnimator应用到RecyclerView.但是,当新的项目添加时,没有看到任何动画.

感谢提前任何想法.

这是我测试过的第一个Android L组件,我正在那里.

这是我的适配器类：

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();
}
}
