java - 如何保存在android中动态添加的多个Edittext的数据？

Question

我有一些 EditText，并且我正在尝试保存它们的值到ArrayList，但是我的使用添加按钮添加 EditText，该按钮添加 LinearLayout，并且 EditText 位于正在创建的 LinearLayout 内。

通常拥有固定数量的EditTexts很容易保存，但是我如何保存连续数量的EditTexts。我在下面的方法 createNewLinearLayout() 中添加 LinearLayouts，并且我想保存来自这些 LinearLayouts 的 EditTexts 的输入。

我怎样才能做到这一点？

我建议:

        for (int i =0;i<LinearLayout.getChildCount();i++)
        {

            EditText edt= new EditText (this);
            edt = LinearLayout.getChildAt(i);
            YourAarraylist[i]=edt.getText().toString();

        }

如果您的 LinearLayout 中有多个 View ，您可以像这样重复 for :

for (int i =0;i<LinearLayout.getChildCount();i++)
    {
        LinearLayout secondLayout= (LinearLayout) LinearLayout.getChildAt(i);
     //   and then:

        EditText edt= new EditText (this);
        edt = secondLayout.getChildAt(indexofyoutEdittext);//You should know this because it's the order of the views you add in your layout

        YourAarraylist[i]=edt.getText().toString();

    }
