Answer 1

may be dependency error. dependencies must be like

dependencies {

    compile 'com.android.support:recyclerview-v7:22.2.0'
    compile 'com.android.support:appcompat-v7:22.2.0'
    compile 'com.android.support:design:22.2.0'
}

Answer 2

1. First update android studio to latest version (beta) 1.3 beta version. [Using menu option 'Check for updates' from android studio]

2. Render your preview using Android M preview.

If you are not able to find the beta update change android studio settings(Updates), then update that patch and render with M preview

To display a sketch you need to delete a line

<tools:showIn="@layout/activity_main"> 

from main RelativeLayout

Answer 4

Edit your code into build.gradle file as below.

compileSdkVersion 24

buildToolsVersion "24.0.2"

compile 'com.android.support:appcompat-v7:24.2.1'

compile 'com.android.support:design:24.2.1'

testCompile 'junit:junit:4.12'

Answer 5

Try to add these dependencies

compile 'com.android.support:appcompat-v7:23.1.1'
compile 'com.android.support:design:23.1.1'

Answer 6

This is a known issue. It is open on the Android Open Source Project Issue Tracker:

https://code.google.com/p/android/issues/detail?id=175595

The workaround described by the Android project member is:

Workaround: Try rendering with M preview using AS v1.3 preview.

Another way to workaround this issue is to replace your android.support.design.widget.CoordinatorLayout with a FrameLayout when you want to edit it in the visual design editor, make your changes to the layout and then change it back to a CoordinatorLayout when you are finished.
