BaseAdapater 中 EditText 中的恢复信息

问题描述

我尝试保存编辑文本的数据。我给你看界面让你知道我的问题。 [这是我的申请][1]

所以我所说的编辑文本在“成分”下。我在我的 baseAdapter 脚本中向您展示了我的函数 getView()：

@Override

public View getView(int position,View convertView,ViewGroup parent) {
    View row = convertView;
    if (row == null) {
        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        row = inflater.inflate(R.layout.add_row_ingredient,null,true);
    }

    Spinner spinner = (Spinner) row.findViewById(R.id.row_typeofquantity);
    if (spinner != null) {
        ArrayAdapter<String> arrayAdapter = new ArrayAdapter<String>(this.context,R.layout.spinner_item,whichunity);

        arrayAdapter.setDropDownViewResource(R.layout.spinner_dropdown_item);
        spinner.setAdapter(arrayAdapter);
        System.out.println(listofingredient.size()+" "+position);

        if (position == spinnerlist.size())
        {
            spinnerlist.add(position,spinner);
        }
        else
        {
            spinnerlist.set(position,spinner);
        }
    }

    EditText name = (EditText) row.findViewById(R.id.edit_name_ingredient);
    if (name != null)
    {
        if (position == editTextArrayListName.size())
        {
            editTextArrayListName.add(position,name);
        }
        else
        {
            editTextArrayListName.set(position,name);
        }

    }
    EditText howmany = (EditText) row.findViewById(R.id.edit_quantity_ingredient);
    if (howmany !=null)
    {


        if (position == editTextArrayListDescription.size()) {
            editTextArrayListDescription.add(position,howmany);
        }
        else
        {
            editTextArrayListDescription.set(position,howmany);
        }

    }
    return row;

}

所以，首先我尝试将我的不同视图放在不同的 ArrayList 中，以便在搜索我需要的不同信息后。此方法适用于微调器，但不适用于编辑文本。 一直以来，我的两个编辑文本在调用函数 gettext() 后什么都不返回。 所以此时，我在不同的论坛（如stackoverflow）中搜索解决方案。我找到了方法：

            public void onFocusChange(View v,boolean hasFocus) {
               if (!hasFocus) {
                  final int position = v.getId();
                  final EditText Caption = (EditText) v;
                  myItems.get(position).className = Caption.getText().toString();
               }
          }
         });

But the problem is that I have an indexoutofrange for v.getId() so,i try to put the position give in paramater of getView() but if i understand well; that can't be work because at the moment of the event function will be called,it takes a random position and not the position of my row in my listView.

So my question how I can solve this problem? 

Thanks for your answer and sorry,my english is far to be perfect.
