import appcompat v7 in eclipse

Question

I set up Android SDK in eclipse, and then have made a project. But I met some error like followings

---

error: Error retrieving parent for item: No resource found that matches the given name 'Theme.AppCompat.Light'

Someone recommends to import the "android-support-v7-appcompat" in "android-sdk/extras/android/support/"

But I cann't fine the directory and file. Instead, I found the file "appcompat-v7-24.0.0" in "C:\Users\user\android-sdks\extras\android\m2repository\com\android\support\appcompat-v7\24.0.0".

I tried to import this file, but Import window of eclipse doesn't display any project. So I can't solve this problem.

How I can solve this problem? Help me...
