在RecycleView列表的Item中若有EditText输入框时，因为ViewHolder复用，所以输入一个Item的数值后，滑动List会在下一个位置也重复出现此数值。

解决方法参考如下：

public class HaoLiaoAdapter extends RecyclerView.Adapter<HaoLiaoAdapter.ViewHolder> {

public void setDataList(ArrayList<RiLiaoBean> dataList) {
    this.dataList = dataList;
    notifyDataSetChanged();
}

private ArrayList<RiLiaoBean> dataList;

public HaoLiaoAdapter() {
    dataList = new ArrayList<>();
}

@Override
public ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
    View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.haoliao_item_layout, parent, false);
    return new ViewHolder(v, new CustomTextWatcher());
}

@Override
public void onBindViewHolder(ViewHolder holder, int position) {
    RiLiaoBean riLiaoBean = dataList.get(position);
    if (riLiaoBean.getType() == 0) {//未上报
        holder.inHaoLiaoEditText.setVisibility(View.VISIBLE);
        holder.haoliaoTextView.setVisibility(View.GONE);
        holder.customTextWatcher.updatePosition(position);
        if(riLiaoBean.getCfhaoqty()>0) {
            holder.inHaoLiaoEditText.setText(riLiaoBean.getCfhaoqty() + "");
        }else {
            holder.inHaoLiaoEditText.setText(null);
        }
    } else {//已上报
        holder.inHaoLiaoEditText.setVisibility(View.GONE);
        holder.haoliaoTextView.setVisibility(View.VISIBLE);
        holder.haoliaoTextView.setText(riLiaoBean.getCfhaoqty() + "包");
    }
    holder.dateTitleTextView.setText(riLiaoBean.getHaoliaodate() + "(" + riLiaoBean.getRiling() + "日龄)");
    holder.biaozhunTextView.setText("标准日耗：" + riLiaoBean.getBzrlh() + "包");

}

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

public class ViewHolder extends RecyclerView.ViewHolder {
    @BindView(R.id.dateTitleTextView)
    TextView dateTitleTextView;
    @BindView(R.id.biaozhunTextView)
    TextView biaozhunTextView;
    @BindView(R.id.haoliaoTextView)
    TextView haoliaoTextView;
    @BindView(R.id.inHaoLiaoEditText)
    EditText inHaoLiaoEditText;
    CustomTextWatcher customTextWatcher;

    public ViewHolder(View view, CustomTextWatcher customTextWatcher) {
        super(view);
        ButterKnife.bind(this, view);
        this.customTextWatcher = customTextWatcher;
        inHaoLiaoEditText.addTextChangedListener(customTextWatcher);
    }
}

private class CustomTextWatcher implements TextWatcher {
    private int position;

    public void updatePosition(int position) {
        this.position = position;
    }

    @Override
    public void beforeTextChanged(CharSequence s, int start, int count, int after) {

    }

    @Override
    public void onTextChanged(CharSequence s, int start, int before, int count) {

    }

    @Override
    public void afterTextChanged(Editable s) {
        if(s.toString()!=null&&!s.toString().equals("")) {
            dataList.get(position).setCfhaoqty(Double.parseDouble(s.toString()));
        }
    }
}

}
