Android relative layout and hide a child that other view defines to be above it

Question

I have a relative layout that has 2 children.
The first child has android:layout_above="@+id/other_child”
I see that if the second child is invisible my layout is working fine.
But is this safe?
What I am trying to do is if the second child is visible to have the first above the other.

该实现看起来不错，但最简单的方法是使用线性布局（即使就性能而言）。
