Problem in xml preview

[ialokim]

Thanks for your issue, I've noticed that too already, but didn't look into it.

If you have some time, could you investigate why exactly this is happening? I suspect the application context required in line 57 to cause the problem. Maybe we could just display a "dummy" flag while in xml preview mode with isInEditMode()?

I think the same thing, we need to use the isInEditMode() method but unfortunately I have not time today to investigate this. I'm going to take a look this weekend 😃

After investigate I added this method in my CustomPhoneInputLayout class :

    @Override
    protected void prepareView() {
         if (!isInEditMode())
            super.prepareView();
    }

It's not the more elegant solution but it works. I can now scroll in the preview mode but the PhoneField layout isn't displayed. To go more deeper I think we can add isInEditMode() in prepareView() by wrapping the adapter (and in all location when it is called) and the editText is still displayed.

Checking this fix with the sample app results in always getting another error:
java.lang.ClassNotFoundException: com.google.i18n.phonenumbers.NumberParseException.

This class is imported in PhoneField.java, but for some reason it is not available while displaying the xml preview. The isInEditMode() method doesn't work in this case as the PhoneInputLayout.java extends the PhoneField and for now, I don't have any other ideas.

Would be great if you could clone the repository and try to preview the sample app's main_layout.xml in your Android Studio version to confirm it's not an odd problem with my local configuration.
