我已经使用recylerview视图适配器创建了动态edittext表单。我需要验证所有空字段。
我在VendorFormActivity上具有“提交”按钮，并且必须从适配器的字段进行提交，因此我已经从适配器创建了单击活动的按钮。
我在提交按钮时也从适配器调用了改造API。
我有四种情况的JSON数据类型：字符串，整数，日期和下拉列表类型，以在Android中创建表单。
问题出在某些字段中，只有字符串类型，如果我一次验证所有内容，应用程序将崩溃，并且仅在最后一个字段中显示验证消息。因此，遇到了问题。
我还需要询问我需要调用哪种方法来调用适配器上的Submit按钮，或者需要从Activity本身进行调用。现在，已经在onBindViewHolder上调用了Submit按钮。
适配器代码发布在这里：

public void onBindViewHolder(final DynamicFormAdapter.MyViewHolder holder, final int position) {

holder.linearLayout.addView(holder.textViewString);
holder.textViewString.setText(formSetting.getLabel());
holder.textViewString.setPadding(24, 4, 24, 2);
holder.textViewString.setTextColor(context.getResources().getColor(R.color.colorTexts));
holder.textViewString.setTextSize(15);
