    You have to do two things:

    • be sure to have imported right appcompat-v7 library in your project structure -> dependencies
    • change the theme in the preview window to not an AppCompat theme. Try with Holo.light or Holo.dark for example.

    Please see the following link – here is where I found a solution that worked for me.

    Rendering problems in Android Studio v 1.1 / 1.2

    Changing the Android Version when rendering layouts worked for me – I flipped it back to 21 and my “Hello World” app then rendered the basic activity_main.xml OK – at 22 I got this error. I borrowed the image from this posting to show you where to click in the Design tab of the XML preview. What is wierd is that when I flip back to 22 the problem is still gone :-).

    I have faced this issue when I introduced additional supporting libraries in my project IntelliJ IDEA

    So for me “File” -> “Invalidate Caches…”, and select “Invalidate and Restart” option to fix this.

    To use the class ActionBarOverlayLayout you need to include this in the dependencies section of build.gradle file:

    compile 'com.android.support:design:24.1.1'
    

    Sync the project once again and then you will find no problem

    I faced this error when I created second activity in my project in the newly updated Android Studio,I solved it simply by copy pasting the whole xml code from first layout to the second and then I just removed the code that’s unnecessary.
