android TextInputLayout changes EditText style after setting error to null

Question

for the first time I\'m using the new Android\'s widget TextInputLayout, it\'s very nice but I\'m facing some problem using setError method

this is my xml

Answer 1

I have a trick to solve this problem simply:

1,new a class extend android.support.design.widget.TextInputEditText ; 2,overrvide getBackground() method ,make it return null;

becasue the method updateEditTextBackground() in TextInputLayout will judge if editText's background drawable is null,and now always return null,result is editText's background will not be changed by error text color.
