找不到处理意图{（有附加）}错误的activity

Question

在activity A中，一旦点击了一个按钮，activity B就会为一个结果启动（startActivityForResult）。在activity B中，用户填写信息并点击一个按钮。单击此按钮后，会添加一些额外的信息，并调用setResult，传递RESULT_OK和意图。

我遇到的问题是将Edittext添加到意图中会导致一个错误消息，即没有处理文本的activity。有没有人知道为什么添加topping1会导致这个错误。

这是错误消息：

Answer 1

完成结果的activity后，不需要添加startActivity（intent）；，而是：

  /*
    rest of your code
  */

  setResult(Activity.RESULT_OK, intent) /* Setting the Result to pass the OK (-1) 
  Result and including the intent with its data. */
  finish() /* Ending the  Activity. */
