Showing video & Images in grid view In android

I am developing an application which has to show images& video in an grid view & all this data comes from server as a json. I got json parsing but very much confused how to show both images & video in single grid view. At the same time if user select any cell of that grid view it must display that contain.

Please give some links and demos for such an application. 

 I think it must work like in bu开发者_如何学Pythonild gallery view in android phone.

Thank You.
