Question

I would like to have an EditText with the background as a \"normal\" EditText but with the error handling of a TextInputEditText (error message appearing at the bottom, and

Arranging the accepted solution with https://stackoverflow.com/a/40379564/2914140 and https://stackoverflow.com/a/44744941/2914140, I wrote another class. When an EditText has a special background (background_1) it changes to a background_2 on error. When the error disappears, it again returns to background_1. No red fill is executed.

public class YourTextInputLayout extends TextInputLayout {

    private Drawable drawable1; // Normal background.
    private Drawable drawable2; // Error background.

    public YourTextInputLayout(Context context) {
        super(context);
    }

    public YourTextInputLayout(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public YourTextInputLayout(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

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

        replaceBackground();
    }

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

        replaceBackground();
    }

    public void setDrawable1(Drawable drawable) {
        this.drawable1 = drawable;
    }

    public void setDrawable2(Drawable drawable) {
        this.drawable2 = drawable;
    }

    private void replaceBackground() {
        EditText editText = getEditText();
        if (editText != null) {
            editText.setBackground(isErrorEnabled() ? drawable2 : drawable1);
            Drawable drawable = editText.getBackground();
            if (drawable != null) {
                drawable.clearColorFilter();
            }
        }
    }
}

In your activity/fragment call after initialization in onCreate() / onCreateView():

YourTextInputLayout inputLayout = ...;
inputLayout.setDrawable1(ContextCompat.getDrawable(getContext(), R.drawable.background_1));
inputLayout.setDrawable2(ContextCompat.getDrawable(getContext(), R.drawable.background_2));

In your XML layout call it by:
