Android Gridview appearing different in a real device

Question

I am currently working on an android application, but I am little confused with the gridview. I have managed to complete the whole code for gridview and I got it right when I run it on the emulator with Nexus 4 and Nexus 7. But when I am running it on a real device (htc 816 G) I am not getting the grid view as desired. Please check my code and help me.

This is what I am getting on emulator
