编辑文本无法正常工作android

Question

您好我正在尝试使用编辑文本进行列表视图，用户可以在其中输入他想要的数字但是我的代码在我添加第一个字符后不断在编辑框之间跳转有没有办法阻止它？我尝试删除获取焦点并删除 addTextWatcher。但是，当我删除 addtextwatcher 时，没有记录文本。如果您需要更多信息，请告诉我，因为我对这个 android 生活有点陌生。这是我的适配器代码： 公共 CreateWKOAdapter（上下文上下文、ArrayList 项、ListView 列表视图） { 充气机 = LayoutInflater.from(context); this.mContext = 上下文； this.items = 项目； this.listview = 列表视图； }

@Override
public int getCount()
{
    return items.size();
}

@Override
public CreateWKOItem getItem(int position)
{
    return items.get(position);
}

@Override
public long getItemId(int position)
{
    return position;
}

@Override
public View getView(int position, View convertView, ViewGroup parent)
{
    ViewHolder holder = null;
    if (convertView == null)
    {
        holder = new ViewHolder();

        convertView = inflater.inflate(R.layout.create_wko_layout_item, null);
        holder.name_text_view = (TextView) convertView.findViewById(R.id.text_name);
        holder.header = convertView.findViewById(R.id.relativeLayout1);
        holder.input = convertView.findViewById(R.id.oclick_layout);
        holder.image_view = (ImageView) convertView.findViewById(R.id.foto_createwko);
        holder.sets_edit_text = (CustomEditText) convertView.findViewById(R.id.sets_edit_text);
        holder.reps_edit_text = (CustomEditText) convertView.findViewById(R.id.rep_edit_text);
        holder.checkbox = (ImageView) convertView.findViewById(R.id.image_chk);

        holder.header.setTag(holder.input);

        convertView.setTag(holder);
    }
    else
    {
        holder = (ViewHolder) convertView.getTag();

    }


    if (visibleindex == position)
    {
        holder.input.setVisibility(View.VISIBLE);
        if(holder.sets_edit_text != null)
        {
            final EditText clone = holder.sets_edit_text;
            holder.sets_edit_text.postDelayed(new Runnable()
            {
                @Override
                public void run()
                {
                    clone.requestFocus();
                    Log.i("su", "Request focus");
                }
            }, 300);
        }
    }
    else
    {
        holder.input.setVisibility(View.GONE);
    }

    CreateWKOItem item = getItem(position);

    if(item.isShouldShowCheckBox())
    {
        holder.checkbox.setVisibility(View.VISIBLE);
    }
    else
    {
        holder.checkbox.setVisibility(View.GONE);
    }
    String image_drawable_str = item.getName().toLowerCase().replace(" ", "_");
    Drawable drawable = getImageFromDrawableByString(image_drawable_str);
    if (drawable != null)
    {
        holder.image_view.setImageDrawable(drawable);
    }
    else
    {
        holder.image_view.setImageResource(R.drawable.bg_count);

    holder.sets_edit_text.setTag(item);
    holder.reps_edit_text.setTag(item);

    holder.sets_edit_text.addTextWatcher();
    holder.reps_edit_text.addTextWatcher();

    holder.header.setOnClickListener(new View.OnClickListener()
    {

Answer 1

简单的解决方案：保留您的 TextBox 侦听器，并将括号留空。也许是安卓？您可能正在查看一个错误。

Answer 2

我要做的是注释掉 notifyDataSetChanged();但仅限于设置代表。
