Android ResourceNotFoundException in preview custom View

I've got a custom view, let's call it CustomView. In the initialization, I call the following method
textPaint.setTypeface(ResourcesCompat.getFont(getContext(),R.font.pretty_font));
In the app, this view works perfectly and the font is displayed as it should but the problem is that the preview of the view wont load in the editor with the following details:
android.content.res.Resources$NotFoundException: Font resource ID
0x7f090000 could not be retrieved.

Why won't this resource be loaded in the editor but it has no problem running in the app?
FYI, MinSdk = 21 and TargetSdk = 28

Don't call setTypeface in design mode. Use:
if (!isInEditMode()) {
textPaint.setTypeface(ResourcesCompat.getFont(getContext(),R.font.pretty_font))
}

I 'm trying to use more the 'android.material.xxx' than support.design.widget.
I also tried the support.design version but it doesn't seems to work :/
What might be the problem here ?
Thanks in advice.

Had the same problem..
Adding the following line of code to your TextInputLayout will fix this issue:
app:passwordToggleDrawable="#string/string_name"
Worked for me

Android Studio not rendering AppCompatButton in preview and design

I have this AppCompatButton :
<android.support.v7.widget.AppCompatButton
android:id="#+id/btn1"
android:layout_width="0dp"
style="#style/buttons_style"
android:text="#string/text1" />
But Android Studio designer preview displays it like this, how can make it update the preview show complete preview? :
There are errors in designer, saying AppCompatButton is raising exceptions while rendering :

i guess he's missing n layout_height attribute in #style/buttons_style

TTS breaks Android Studio's layout preview renderer

I have a custom layout (extends LinearLayout) which implements the TextToSpeech.OnInitListener interface. Everything works fine except when opening an activity which contains this layout in Android Studio's editor.
The render of the preview fails because Android Studio can't find the TextToSpeech.OnInitListener class :

I've already tried to rebuild, clear the cache, refresh the layout, remove the implements of my layout class and replace it with a plain listener, and to put every TTS related code inside a if (!this.isInEditMode) block, with no success.
Could you help me ?

failed to convert OK into a drawable
The graphics preview in the layout may not be accurate
Paint setShadowLayer is not supported
I've booted up Android Studio and have a couple of views laid out on the XML; except they do not show up on the preview! I can only assume this means that android studio is not drawing whatever is on the XML; any explanation as to why? What can I do so that android studio 'draws' it?
