Question

基本上我想要的是：当一个人回答＆＃34;没有＆＃34;单击按钮（否）我希望空文本视图更改为＆＃34;为什么？＆＃34;然后他们可以在edittext框中输入原因。然后最后一堂课可以列出所有问题。机器人。

 //I've tried a setText, super, etc. But I just can't get it right. Thanks in advance.

Answer 1

如果你的意思是按课程进行，那么，您可以使用EditTextInstance.getText()，然后您可以使用构造函数＆＃39;将此返回的字符串传递给其他活动（通过intent.putExtra()）或类＆＃39;。

Answer 2

使用putExtra（）发送字符串“为什么？”或者其他的东西。使用getString（）;

检索它

如何在另一个类的List中设置EditText？
