Question

我有一个按钮，当我单击它时，该表单将在表单上添加更多的 edittext （我正在使用 addView ）。当我需要“添加更多商品”时，就像订单。

单击“保存”按钮时，如何获得所有edittext值？

View moreItem = inflater.inflate(R.layout.add_item, (LinearLayout) findViewById(R.id.linearItem), false);
final LinearLayout linearForm = (LinearLayout)findViewById(R.id.linearItem);
linearForm.addView(moreItem);

编辑文本位于R.layout.add_item

内部

Answer 1

在将editText至addView()添加到父视图时，可以通过运行循环来获取所有editText值。在“提交”按钮clickListener内，添加以下代码：

int count = parentLayout.getChildCount();
String[] editTextValues = new String[count];
    for (int i = 0; i < count; i++) {
        View view = parentlayout.getChildAt(i);          
        if (view instanceof EditText) {
            EditText edittext = (EditText) view;
            editTextValues[i] = editText.getText().toString();
        }
    }

Answer 2

感谢所有回复。

我创建一个clickcount变量以计算每个添加按钮的点击次数。我已经用

解决了这个问题

editText.setTag("et"+clickcount); //When I add more button

并进行for循环

for (int i = 1; i <= clickcount; i++) {
   editText= resultView.findViewWithTag("et"+i);
   String text= editText.getText().toString();
}

感谢 jitesh mohite 使用getTag（）的想法

最终列表edittext = new ArrayList <>（）; 按钮addbutton; 将每个值存储在列表中，并在需要的位置进行检索
