我有一个线性布局，里面有3个不同的相对布局。我想将这个根线性布局分成3个相等的部分。我已经将线性布局中的权重总和设置为3，每个亲戚的宽度都设置为0。我隐藏了这个亲戚中的一个，其他两个没有按预期居中。这是xml代码

You have to visibility gone of Relative layout. 您必须消除相对布局的可见性。
NumeroPreventivi.setVisibility(View.GONE);
have you visibility gone or invisible of Relative Layout?because if you doing visibility gone of layout then its work perfectly and if you are doing visibility invisible then this layout existence true. 您是否对相对布局的可见性消失了或看不见？因为如果您对布局的可见性消失了，那么它的工作就完美了；如果您对可见性进行了隐藏，那么该布局就成立了。 i mean this layout take area of layout. 我的意思是这种布局占据了布局面积。
at run time you have to change weight sum of layouts. 在运行时，您必须更改布局的权重总和。
