记录几段常用的与状态栏有关的代码，备做不时之需。

实现沉浸式状态栏，kotlin代码：

fun steepStatusBar() {


    var release=android.os.Build.MODEL
    if (release!=null){
        if (release.contains("HUAWEI")){
            var  window = window
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        }

    }

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            //5.x开始需要把颜色设置透明，否则导航栏会呈现系统默认的浅灰色
            var  window = window
            var  decorView = window.decorView
            //两个 flag 要结合使用，表示让应用的主体内容占用系统状态栏的空间
            var option = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
            decorView.systemUiVisibility = option
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
            window.statusBarColor = Color.TRANSPARENT
        } else {
            var  window = window
            var attributes = window.attributes
            var  flagTranslucentStatus = WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS
            var  flagTranslucentNavigation = WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION
            attributes.flags = flagTranslucentStatus
            attributes.flags = flagTranslucentNavigation
            window.attributes = attributes
        }
    }
}

动态设置隐藏或显示状态栏，kotlin代码：

        window.addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN) //隐藏状态栏
//        window.clearFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN) //显示状态栏
