Unity在5.3以上的版本里把状态栏的显隐功能去掉了，但是iOS的没有去掉，果然安卓不是亲儿子啊，前两天做项目，需要这个功能，我开发用的是5.6版本，怎么找都没找到这个功能，还以为放在其他地方了呢，还特意去官网看了Unity的更新内容，结果百度了一下，果然5.3以后，安卓就没有这个功能了。后来在网上看到有人写了两个代码，就把这个问题搞定了，我稍微整理了一下，下面放代码。

上面的代码是调用了Unity打包成安卓后自动生成的UnityPlayerActivity类里面的状态栏显示隐藏的方法，所以不需要任何其他的安卓的jar包。文章源自大腿Plus-https://www.zhaoshijun.com/archives/513

可以直接将上面的代码拖到任意一个GameObject上，但是只有发布出来后才能看到效果。文章源自大腿Plus-https://www.zhaoshijun.com/archives/513 文章源自大腿Plus-https://www.zhaoshijun.com/archives/513

你好，我用这个出现一个问题， 5.3的时候mUnityPlayer.setOnSystemUiVisibilityChangeListener是好着的，5.5之后我在安卓部分添加了 mUnityPlayer.setOnSystemUiVisibilityChangeListener 函数后，发现这个函数并不能完全监听到所有的消息，有时候会丢消息，导致我的显示有时候会有问题， 我可以留个QQ交流下 493213418

@ Rex 这个可能和Unity版本的问题，我记得在哪个版本里面Unity的Activity里面的内容发生了一些变化，还用之前的方法可能会存在问题。

哦，那有没有什么参考可以说下，这部分内容用的人比较少~~ 困扰很久了~
B1
@ Rex 这个我也没怎么用过，可以问一下安卓原生开发的人，好久没有碰安卓原生的东西了，我也不太清楚了。

@ 大腿Plus 好的，谢谢了

你好 这种方法很实用 我想问一下 有什么方法可以获取状态栏的高度吗 因为不同机型他的状态栏高度不一样 如果有的话 可以尽量说详细点
B1
@ 上面有个状态栏样式的那个可以控制占用上方屏幕的像素，不用去获取状态栏宽度，只要设置好UI锚点应该不会有什么问题
