It seems there is no way to get screenshot from screen of a device that is not rooted.Here,CommonsWare says:

If you mean "screenshot of somebody else's activity", that is not supported, for obvious privacy and security reasons.

Although you can get screenshot of emulator when your App is running!

Edit:

But there exists a library that is called ASL(Android Screenshot Library):

Android Screenshot Library (ASL) enables to programmatically capture screenshots from Android devices without requirement of having root access privileges. Instead, ASL utilizes a native service running in the background, started via the Android Debug Bridge (ADB) once per device boot.

I did not try it,but you can see more details in about it here.
