篇首语:本文由小常识网(cha138.com)小编为大家整理,主要介绍了如何在cordova-plugin-statusbar插件基础上增加获取状态栏高度功能相关的知识,希望对你有一定的参考价值。
最近做项目,有一个功能需求需要获取状态栏高度,但是遍寻各种插件,都没有此功能,自己又不会写原生代码,很无奈。但是在cordova-plugin-statusbar插件git仓库的issues里,看到有人提出了同样的需求,并且有人实现了这个功能且发起了pr,只是插件官方并没有合并到主分支上且release新版本。于是,自己去合并请求的仓库里找到了相关代码,加到了自己本地的插件代码里。目前仅实践了android,所以先把安卓相关的改动贴出来记录一下(红色代码部分),之后实践了ios后再来补上。
PS:如果已经添加了platform的话,直接修改plugins里面的内容,打包的时候是不会生效的,所以要么去平台编译后的代码里添加修改,或者修改后重新添加platform
