Android Studio Err Msg: Render Problem. Failed to find sytle 'coordinatorLayoutStyle' in current theme.

Hi there,

As a complete noobie in this field i have the same issue. but where do i add these lines?
Under R.values.styles in the styles.xml i found similar lines but when i delete thoses and add these it gives me an error messege.

these are the lines already there

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

and when i replace them with your lines it marks @style/Widget.Design.CoordinatorLayout with red and gives tme the error messege:
Cant resolve symbol '@style/Widget.Design.CoordinatorLayout'
Validates recource reference inside Android XML files.

Thx for any Help,
Leon

Insert this line as below into the application theme.

<style name="AppTheme.NoActionBar">
<item name="coordinatorLayoutStyle">@style/Widget.Design.CoordinatorLayout</item>
</style>

I just forgot to Quote your comment in mine

Add the two dependencies in your build.gradle(app) :
dependencies {
implementation 'com.android.support:appcompat-v7:27.0.2'
implementation 'com.android.support:design:27.0.2'
}

And, instead of 27.0.2, use your library version( i.e 28.x.x ).

Thanks alot for the fast reply.

Those 2 dependencies are already my build.gradle(app) but its 28.0.0-apha3.

Does that change anything?

Leon

If you already have those 2 dependcies, then keep your old style name="AppTheme.NoActionBar" and try to build. Do you have any error messages?

I can build but i still get an error:
Render Problem
Failed to find style 'coordinatorLayoutStyle' in current theme

On a different forum i found out that if you change the 28.0.0-alpha3 to 28.0.0-alpha1 then it sovles the Render Problem
Failed to load AppCompat ActionBar with unknown error.

but now if im getting the Error NullPointerException and i dont know why

By 'keep your old style…', I mean that style without 'coordinatorLayoutStyle' in your style.xml.
If that, will you still get error msg 'Failed to find style 'coordinatorLayoutStyle' ?

I dont have a style with coordinator in it :/ .

This is the code in styles.xml

<resources>

<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
    <!-- Customize your theme here. -->
    <item name="colorPrimary">@color/colorPrimary</item>
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item>
    <item name="colorAccent">@color/colorAccent</item>
</style>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
</style>

<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />

<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />

There also is a styles.xml (v21) what is that and what does it mean?

Code from that one:

<resources>

<style name="AppTheme.NoActionBar">
    <item name="windowActionBar">false</item>
    <item name="windowNoTitle">true</item>
    <item name="android:statusBarColor">@android:color/transparent</item>
</style>

The Codes and Programmes written over here is damn perfect and perfect solution for the queries over here, I would really like to thank the developers for sharing it. Really appreciate it .

My android studio is only V2.2.3. I could not reproduce the issue when I created a new simple 'hello world' app today at home.
Hope some friends else with the V3.1.2 of Android Studio will help you. Sorry.

On a different forum i found out that if you change the 28.0.0-alpha3 to 28.0.0-alpha1 then it sovles the Render Problem

I'm using android studio 3.1.2 and got same problem. When i change the library from alpha3 to alpha1, it works. If you still got errors, maybe you need to rebuild

Hey, its been some time since i checked back on this post since i managed to fix the issue with your idea. but untis now i have always been using empty activities. today its the first time i am using a basic activity. aaaaand the problem is back. If you have any ideas id be thrilled to hear them!!!

Hello,

I am actually getting the same trouble, and your answer will be very helpful.

However, I am not sure where exactly should I put the code you mentioned (below)

<style name="AppTheme.NoActionBar">
<item name="coordinatorLayoutStyle">@style/Widget.Design.CoordinatorLayout</item>
</style>

I am opening "content_main.xml" on Android Studio.
And do not know where exactly.

Thank you
