将动态生成的表单的edittext数据保存到服务器

Question

我已经根据后端提供的json数据根据类型即String、int和spinner生成了动态表单。

1. 我创建了一个 recylerview 适配器，并在 pojo 类中添加了额外的变量作为答案，并为它提供了 setter 方法。

2. 现在，表单已根据类型生成，但我需要将数据保存到服务器。为了保存数据，我需要使用各自的 id 和类型获取每个 edittext 值，我需要循环它，但我不能这样做。我无法使用其 ID 和类型定义 edittext 值。我希望你们能帮助我。

3. 在方法 callRetrofitSaveForm() i 中有三个参数要发布到服务器。供应商 ID，ii。用户身份 iii. formData，我对 param iii 有疑问，因为它有要传递的格式。我用改造来解析，问题出在第三个参数formData。

第三个参数的取值格式是

 [{"id":"24","label":"Customer ID","value":"102"},{"id":"25","label":"Amount","value":"2000"}]

我的适配器

 @Override
public void onBindViewHolder(MyViewHolder holder, int position) {
    HelpForm.FormSetting formSetting=formArrayList.get(position);
    final String description = formArrayList.get(position).getLabel();
    Log.d("cjjdnjcnjd",description);

    if (formSetting.getType().equals("STRING")){
        Log.d("dndjkd",String.valueOf(holder.getAdapterPosition()));
        holder.textViewString = new TextView(activity);
        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);
        holder.editTextString = new EditText(activity);
        holder.linearLayout.addView(holder.editTextString);
        editTextListString.add(holder.editTextString);
    }
    if (formSetting.getType().equals("INT")){
        holder.textViewInt = new TextView(activity);
        holder.linearLayout.addView(holder.textViewInt);
        holder.textViewInt.setText(formSetting.getLabel());
        holder.textViewInt.setPadding(24, 4, 24, 2);
        holder.textViewInt.setTextColor(context.getResources().getColor(R.color.colorTexts));
        holder.textViewInt.setTextSize(15);

        holder.editTextINT = new EditText(activity);
        holder.linearLayout.addView(holder.editTextINT);

    }

    if (formSetting.getType().equals("DATE")){
        holder.textViewDate = new TextView(activity);
        holder.linearLayout.addView(holder.textViewDate);
        holder.textViewDate.setText(formSetting.getLabel());

        holder.textViewDate.setPadding(24, 4, 24, 2);
        holder.textViewDate.setTextColor(context.getResources().getColor(R.color.colorTexts));
        holder.textViewDate.setTextSize(15);

        holder.editTextDate = new EditText(activity);
        holder.linearLayout.addView(holder.editTextDate);
    }

    if(formSetting.getType().equals("DROPDOWN")){
         holder.textViewSpinner = new TextView(context);
        holder.linearLayout.addView(holder.textViewSpinner);
        holder.textViewSpinner.setText(formSetting.getLabel());
        holder.textViewSpinner.setPadding(16, 4, 8, 4);

        holder.spinner = new Spinner(context);
        holder.linearLayout.addView(holder.spinner);


        ArrayList<String> err = new ArrayList<>();
        err = formSetting.getOptions();
        holder.spinner.setAdapter(new ArrayAdapter<String>(context, android.R.layout.simple_dropdown_item_1line, err));

    }


    VendorFormActivity.save.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            callRetrofitSaveForm();
        }
    });

}

@Override
public int getItemCount() {

    return formArrayList.size();

}

public class MyViewHolder extends RecyclerView.ViewHolder {

    TextView textViewString,textViewInt,textViewDate;
    LinearLayout linearLayout;
    EditText editTextString,editTextINT,editTextDate;
    Spinner spinner;
    TextView textViewSpinner;


    public MyViewHolder(View itemView) {
        super(itemView);
        linearLayout=itemView.findViewById(R.id.dynamiccontainer);
    }
}

Answer 1

您可以抓取父视图并循环遍历它并获取所有editText。

private HashSet<EditText> getTextViews(ViewGroup root){
    HashSet<EditText> views=new HashSet<>();
    for(int i=0;i<root.getChildCount();i++){
        View v=root.getChildAt(i);
        if(v instanceof EditText){
            views.add((EditText)v);
        }else if(v instanceof ViewGroup){
            views.addAll(getTextViews((ViewGroup)v));
        }
    }
    return views;
}
