我正在尝试从 web 服务获取数据并根据 web 服务的响应创建动态自定义字段。然后用户将填写字段，然后单击上传按钮后，它将数据从动态自定义字段发送到网络服务，然后开始上传。我想知道如何从自定义字段中获取数据，因为它们是动态创建的，我无法访问它们。这是我的代码。这是我在从 web 服务获得响应后创建字段的图片，我需要您的帮助。

如果我理解正确，您的问题是从动态创建的字段中获取数据。EditText您可以通过保存在您的类中动态创建的来解决它。

这是您保存字段的代码（我没有检查语法）。我已经用 //BUBBLE 注释标记了更改的块。

简而言之，我创建了一个 ArrayListEditText

private List<EditText> dynaFields = null;

然后列表在字段创建之前被实例化：

// BUBBLE create a list with the exact size of input fields
this.dynaFields = new ArrayList<EditText>(WebData.size());

最后，一旦创建了字段，我就将它们添加到列表和视图中：

// instantiate and add the current field to the list and view
EditText newField = new EditText(this);
this.dynaFields.add (newField)
layout.addView(newField);

我在你的 if 语句中做了一些小的简化，所以我可以只使用一个 EditText 对象。

要获取组件，只需在 onClick 方法中遍历数组：

public void onClick(View arg0)
{
    TextField currText;
    for (currText : UploaderActivity.this.dynaFields) {
     // TODO: get the current EditText text and have fun!
    }    
}

创建时在 EditText 对象上设置标签（result.Id），然后浏览主布局，然后

int mainChildsCount = mainGroup.getChildCount();
for(int i=0;i<mainChildsCount;i++){
    View v = mainGroup.getChildAt(i);   
    if(v instanceof EditText){
        //recognize them here by their tags     
    }
}

Take

int dynId = 1001;

Now, when you are creating EditTexts dynamically, set their ids by using

.setId(dynId++);

Then at the time of sending EditTexts' data to web-service; retrive values from EditTexts by getting them using ID you have seted at the time of creating.

At time of retriving, you can start retriving using 1001 and increment them by 1.

use this :

    String unm, pwd;

    YourComponent.setOnClickListener(new View.OnClickListener() {  //  OR  In  onClick

                @Override
                public void onClick(View arg0)
                {
                     unm = username.getText().toString();
                     pwd = password.getText().toString();
                }
            });

Now, use these unm and pwd strings.

You can get the components by their ID's 

for (int i = 1001; i < 1001 + componentCount; i++) {
  View currView = getViewById (i);
  if (currView instanceof EditText) { 
      EditText currentComponent = (EditText) currView;
  }
}
