Answer 1

In order to set color in grid cell while inflating grid cell's layout, in your baseadapter class create a cell's array then set the color as you wish.

Like

LayoutInflater li = (LayoutInflater) mContext
                .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        grd = li.inflate(R.layout.grid_item, null);
FrameLayout dgcl = (FrameLayout) grd.findViewById(R.id.grditm);
        parent_l[position] = dgcl;

then

parent_l[21].setBackgroundColor(Color.RED);

here griditm is the id of the layout grid_item
