Android滚动视图无法正常运行时不能在屏幕上显示
[英]Android scroll view does not work well fits on the screen when it should not
问题描述
My project is to create the email field dynamic , in the sense that I can have one, two , and others. 
我的项目是创建动态的email字段，从这个意义上讲，我可以拥有一个，两个和其他字段。 So I thought about putting the whole right side with the details in a ScrollView . 因此，我考虑将整个右侧和详细信息放在ScrollView中。 The problem is that the scroolview never appears , is not scrollable and can not figure out what is wrong ,I would not want that would fit onto the screen but you can scroll . 问题是scroolview永远不会出现，无法滚动并且无法找出问题所在，我不希望它适合屏幕，但是您可以滚动。 can someone help me ? 有人能帮我吗 ？ thanks so much 非常感谢

Try to only use ScrollView for various email EditText and also given weight to ScrollView so it will taken rest space for showing multiple email EditText : 尝试仅对各种电子邮件EditText使用ScrollView，还要对ScrollView赋予权重，这样它将占用余下空间来显示多个电子邮件EditText：
