从动态创建的编辑文本字段中获取数据，然后单击上传按钮将其发送到Web服务

Question

我试图从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，用户将填写这些字段，然后单击“上载”按钮后，它将把数据从动态自定义字段发送到Web服务，然后开始上载。 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，所以我无法访问它们。 这是我的代码。 这是我从网络服务获得响应后创建字段的照片，我需要您的帮助。

Answer 1

如果我理解正确，那么您的问题是从动态创建的字段获取数据。 您可以通过将动态创建的EditText保存在类中来解决此问题。

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。

        }//end of If request code
      }//end of If result code
    }//end of onActivityResult
}//end of main

简而言之，我创建了一个EditText的ArrayList。

private List<EditText> dynaFields = null;

然后，在创建字段之前就实例化了该列表：

// 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);

我在您的if语句中做了一些小的简化，因此我只能使用一个EditText对象。

要获取组件，只需在onClick方法中遍历数组即可：

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

Answer 2

在创建EditText对象时设置它们的标签（result.Id），然后浏览您的主布局，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     
    }
}

Answer 3

采取

int dynId = 1001;

现在，当您动态创建EditText时，请使用以下命令设置其ID

.setId(dynId++);

然后，在将EditTexts的数据发送到Web服务时； 通过使用您在创建时设置的ID来获取EditTexts中的值。

检索时，您可以使用1001开始检索并将其递增1。

用这个 ：

    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();
                }
            });

现在，使用这些unm和pwd字符串。

您可以通过其ID获得组件

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