我无法在布局中找到微调框和编辑文本

代码如下所示，它只能多次查找出EditText

try {
                int count = my_linear_layout1.getChildCount();
                //EditText ed[] = new EditText[count];
                for (int i = 1; i < count; i++) {
                    View row = my_linear_layout1.getChildAt(i);

                    row = my_linear_layout1.findFocus();
                    if(row instanceof EditText)
                    {
                        // you got the Edit Text  if (v.getClass().equals(TextView.class))
                        EditText textOut = (EditText) row.findViewById(R.id.OBSpn);
                        String data = textOut.getText().toString();
                    }

                    else if(row instanceof Spinner)
                    {
                        // you got the Spinner
                        Spinner Spin = (Spinner) row.findViewById(R.id.SPNOBS);
                        String data1 = Spin.getSelectedItem().toString();
                    }

                }

            } catch (Exception e) {
                e.printStackTrace();
            }

使用ListView代替LinearLayout。遵循此文档。 https://developer.android.com/reference/android/widget/ListView

我的问题是为什么ScrollView不能成为父布局，而不需要相对布局。
