First in your girdview adapter class take on variable exp.

int selected;

then make on method in grid view like that

public void selectedPosition(int postion) 
{
    selected = postion;
}

then you can also put a code in getview method of gridview. Like this

 if(position==selected)
 {
     imageView.setBackgroundColor(Color.WHITE);
 }
 else
 {
     imageView.setBackgroundColor(Color.parseColor("#578FFF"));
 }

now in onitemclick of grid view you can post like that

adapter.selectcrop(position);
adapter.notifyDataSetChanged();

here is a solution example I will give you step by step i think you can solve your problem using that.
