Question

this is my xml

Answer 1

I ran into similar problem and found a simple solution for it. This problem occurs if we set a custom background drawable/color to the EditText inside the TextInputLayout. Solution to this would be to subclass the the TextInputLayout and override the setError() and drawableStateChanged() methods and set our custom drawable/color as the EditText's background again. For Example, I had a rounded corner drawable set for my EditText's background, below is my subclass,

public class RoundedBorderedTextInputLayout extends TextInputLayout {
    private Context context;

    public RoundedBorderedTextInputLayout(Context context) {
        super(context);
        this.context = context;
    }

    public RoundedBorderedTextInputLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
        this.context = context;
    }

    public RoundedBorderedTextInputLayout(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
        this.context = context;
    }

    @Override
    protected void drawableStateChanged() {
        super.drawableStateChanged();

        EditText editText = getEditText();
        if(editText != null) {
            editText.setBackground(ContextCompat.getDrawable(this.context, R.drawable.custom_rounded_edittext));
        }
    }

    @Override
    public void setError(@Nullable final CharSequence error) {
        super.setError(error);

        EditText editText = getEditText();
        if(editText != null) {
            editText.setBackground(ContextCompat.getDrawable(this.context, R.drawable.custom_rounded_edittext));
        }
    }
}

And then use your custom class in the xml,

Hope this helps. Happy Android coding :)
