/**
 * Edit text that removes hint when it is focused.
 * If text is centered horizontally and hint is set, on some devices cursor can look ugly in the center of hint.
 * So, this editText automatically hides hint when focus is on, and shows it back when focus is out
 * <p>
 * ! Important !
 * Use {@link #setSavedHint(CharSequence)} instead of {@link #setHint(CharSequence)}
