防止TextInputLayout使TextInputEditText更高

问题描述

我想要该密码切换功能，看来TextInputLayout具有该功能，而不是TextInputEditText.但是，正如您在下面的代码中看到的那样，即使我将高度设置为wrap_content和app:hintEnabled="false"，但是TextInputEditText的高度也会变高，如果TextInputEditText在TextInputLayout中.将其与TextInputLayout之外的TextInputEditText的高度进行比较.

I want that password toggle feature, and it seems TextInputLayout has that feature, not TextInputEditText. But as you see the code below, even though I set the height to wrap_content and app:hintEnabled="false", the height of TextInputEditTextgets taller if the TextInputEditText is in TextInputLayout. Compare that to the height of the TextInputEditText outside the TextInputLayout.

由于我不使用该提示动画，因此不需要TextInputLayout来增加TextInputEditText的高度.如何防止TextInputLayout增加TextInputEditText的高度?

Since I do not use that hint animation, there is no need that the TextInputLayout to increase the height of TextInputEditText. How can I prevent TextInputLayout from increasing the height of TextInputEditText?

推荐答案

到目前为止，我发现的唯一解决方案是将android:layout_height设置为固定大小.例如40dp.

Only solution I have found so far is to set android:layout_height to fixed size. For example 40dp.
