i have found alternative. alternative not looking for. love learn explanation of this.
the layout_marginleft , layout_marginright much.
remove margins first, see view properly. start addding margins again accordingly.
there few things need observer here.
layout_marginbottom pushing left_corner far center_parent
layout_marginright pushing left_corner far center_parent have make mind on want controls places , aligned what.
