Multiline does not work inside TextInputLayout

问题

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.

回答1:

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

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.

This works too:

android:inputType="textPersonName | textMultiLine"
