View margin not working after using databinding

Below is the code of the item layout of gridview. In this, the layout_margin is there in the design panel but when I run the there is no margin. I tried to check other tags like the background and found that it was working. A similar problem is with the layout_weights of linear_layout, the are also not working. These were working fine without data binding. Can someone please help me out in resolving this? '''
