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

Action bar rendering issue

I am new to Android Studio. I had this action bar disappearing in design panel. Basically nothing was being rendered on the design view. no action bar no textView nothing. then i read that i should switch my theme to some other theme and that worked but i wanted to keep the normal apptheme. API changing didnt do anything to it.
what worked was:
changing the appcompat line in build.gradle to
implementation 'com.android.support:appcompat-v7:26.0.0-beta1'
it started working like a charm until today.I was learning how fragments work so i made two blank fragments and the rendering issue came again. just to check it wasnt some bad luck:
I made a new project.
problem was there.
changed build.gradle file.
problem disappeared.
added 2 blank frags (with xml) to the proj.
problem came again.
now ill tell you what all ive done which doesnt work for me:
updated android studio
build.gradle appcompat code change
theme change (works but i want apptheme)
API change
changing style.xml(brings back textView in the design view but not the action bar)
please help.following is the stack :

It could be the version of appcompat you using in your build gradle, I had the same problem using
implementation 'com.android.support:appcompat-v7:28.0.0-alpha3'
so I just used
implementation 'com.android.support:appcompat-v7:28.0.0-alpha1'

and the following error message
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?

Not sure what the issue is, i triad all the solutions already available on stackoverflow which says some issue with 9 patch image not updated properly but nothing helped. Note: this error only comes the moment I add seekbar control in xml.
Thanks

It seems this is an issue and it is being handled by google HERE:
Some other people are facing the same issue and the fix is always to change the preview API from 24 to 23 (or any other version).
You may need to download a previous version of SDK.. You don't need to change your build.gradle... Just download the SDK and Android Studio will allow you to change the SDK in Layout Preview
