EditText 与适配器有问题

    public class AdapterList extends RecyclerView.Adapter<AdapterList.ParentViewHolder>{
    private String mDataSet[];
    private Context context;

    public AdapterList(Context context,String data[]) {
        mDataSet = data;
        this.context=context;
    }

    @Override
    public ParentViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
        return new ParentViewHolder(LayoutInflater.from(context).inflate( R.layout.adap,null ));
    }

    @Override
    public void onBindViewHolder(final ParentViewHolder holder, final int position) {
//        holder.anameTxtView.setText(mDataSet.get(position).getDname());
//        holder.abalanceTxtView.setText(mDataSet.get(position).getDbalance());
        holder.editText.setText( mDataSet[position] );

        holder.editText.setOnFocusChangeListener(new View.OnFocusChangeListener() {
            @Override
            public void onFocusChange(View v, boolean hasFocus) {
                if (!hasFocus){
                    String str=holder.editText.getText().toString();
                    holder.editText.setText( str );
                    mDataSet[position]=str;
                }
            }
        });

    }


    @Override
    public int getItemCount() {
        return mDataSet.length;
    }

    class ParentViewHolder extends RecyclerView.ViewHolder {
        private EditText editText;

        public ParentViewHolder(View itemView) {
            super(itemView);
            editText= (EditText) itemView.findViewById(R.id.text);
        }
    }
}

我想看着 gif 一切都会清楚我的问题是什么

适配器
