多行在TextInputLayout中不起作用 [英] Multiline does not work inside TextInputLayout

问题描述

无论我做什么，我都无法使EditText在TextInputLayout中多行显示(必须为字符计数器添加InputLayout). 因此，当我输入内容时，它会水平移动，而不是过一会再换行. 如您所知，在普通EditText内，多行可以解决问题，但在这种情况下不行.你怎么认为?谢谢.

Whatever I do, I couldn’t manage to make my EditText multilined inside TextInputLayout (had to add InputLayout for character counter). So when I enter something, it goes horizontally instead of going to a new line after a while. As you know very well, inside normal EditTexts, multiline does the trick but not in this case. What do you think? Thank you.

推荐答案

我做到了.您必须为相关的EditText添加以编程方式" edittext.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_MULTI_LINE);.

I did it. You have to add 'programatically' edittext.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_FLAG_MULTI_LINE); for your related EditText.

在我的情况下，有趣的是，当您将多行代码添加到xml多行时不起作用(使用TextInputLayout)，但是这种方式有效.希望对我们中的一些人有帮助.

The interesting thing in my case is when you add multiline code to xml multiline does not work(with TextInputLayout) but it works this way. Hope it s helpful for some of us.
