如何以编程方式为LinearLayout指定layout_below？

Question

我想以编程方式执行此类操作 -

<RelativeLayout1>
  <LinearLayout name = 1>
  <LinearLayout below = 1>
<RelativeLayout1>

我试着这样做:

LinearLayout.LayoutParams params = (LinearLayout.LayoutParams)mButtonContainer.getLayoutParams();

params有weight田野,width田野,但没有layout_below...感谢您的帮助!

同 addRule

RelativeLayout.LayoutParams relativeParams = new RelativeLayout.LayoutParams(LayoutParams.FILL_PARENT, LayoutParams.FILL_PARENT);
relativeParams.addRule(RelativeLayout.BELOW, idOfTheViewBelow);
