//dgel's solution doesn't work for me: when I tap on the picker, formatting disappears again.This bug is caused by input filter set on EditText inside NumberPicker when setDisplayValues isn't used. So I came up with this workaround:
var mInputTextField = java.lang.Class.forName("android.widget.NumberPicker").getDeclaredField("mInputText");
mInputTextField.setAccessible(true);
var mInputText = <android.widget.EditText>mInputTextField.get(this._android);
mInputText.setFilters([]);
}
}
