setError EditText (в) врежется

Question

Я пытаюсь использовать метод setError() на EditText, но каждый раз, когда он выходит из строя с этим журналом:

Я звоню setError обычно внутри фрагмента, например:

mEditText.setError("test") 

Может кто-нибудь мне помочь?

Answer 1

Я использовал библиотеку MaterialEditText для воспроизведения свойства Floating Label Lollipop в KitKat .. потому что несколько месяцев назад AppCompat все еще не выполнял эту работу. Эта проблема возникала только тогда, когда я пытался установитьError на MaterialEditText. Я обновил AppCompat до самой новой версии + TextInputLayout + Android EditText, и я получил все, что работает правильно: метод setError и плавающая метка как в KitKat, так и в Lollipop.
