将子视图添加到两个布局(多个父级)

Question

我想将相同的视图添加到之前添加到另一个的新RelativeLayout.

 RelativeLayout1
   -- View1
   -- ScrollView
      -- Linear Layout2

我有一个视图添加到线性layout2,它被添加到scrollview.我想将相同的子视图添加到View1的RelativeLayout1.

我这样添加视图,

MyCustomScrollView scrollView = new MyCustomScrollView(context);
  layout2 = new LinearLayout(context);

  for(int i=0;i<10;i++)
     layout2.addView(list.get(i));

  scrollView,add(layout2);
  relativeLayout1.addView(scrollView);

现在我想在View1的位置将相同的视图从列表添加到RelativeLayout1

 RelativeLayout1.remove(view1);
 RelativeLayout1.addView(list.get(0),0);

A View不能是两个ViewGroup父母的孩子.

随意克隆View并将克隆添加到第二个父级.
