Android RelativeLayout用纯java设置margin的办法

RelativeLayout rl =    new RelativeLayout(this);    
           
            MarginLayoutParams mp = new MarginLayoutParams(20,20);  //item的宽高
            mp.setMargins(0, 0, 25, 0);//分别是margin_top那四个属性
            RelativeLayout.LayoutParams lp = new RelativeLayout.LayoutParams(mp);
            lp.addRule(RelativeLayout.ALIGN_PARENT_RIGHT);
           
            Button bt = new Button(this);
            bt.setLayoutParams(lp);
           
            rl.addView(bt);
