记录我的bug，关于setVisibility()出现的奇怪问题

啥都不说，先看代码

RelativeLayout insuranceChild = (RelativeLayout) findViewById(R.id.insuranceChild);
insuranceChild.setVisibility(View.GONE);

RelativeLayout insuranceAgecoverAge = (RelativeLayout) findViewById(R.id.insuranceAgecoverAge);
insuranceAgecoverAge.setVisibility(View.GONE);

RelativeLayout insuranceLimit = (RelativeLayout) findViewById(R.id.insuranceLimit);
insuranceLimit.setVisibility(View.VISIBLE);

没有什么问题吧，外层是linearLayout,下面还有其他布局，但是，模拟器，nexus5没问题，在小米，三星就出现下面的布局全部消失的情况，一个劲的找啊，
然后看布局

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

看起来也没有问题吧，奇怪的是，三个RelateLayout必须两个以上显示，才会正常，毫无头绪寻找

最后

就说一个词

view

杨峥啊，你这布局
