Android5.0以上状态栏沉浸式简单适配

Activity初始化onCreate中调用如下方法即可

override fun initUI() {
        setSupportActionBar(binding.toolbar)//设置toolbar
        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
            val window: Window = activity.window
            val decorView: View = window.getDecorView()
            if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {
                //fitsSystemWindows过时替代方法--安卓11及以上才有windowInsetsController
                decorView.windowInsetsController?.systemBarsBehavior =
                    WindowInsetsController.BEHAVIOR_SHOW_BARS_BY_SWIPE
            } else {
                //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
                val option: Int = (View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
                        or View.SYSTEM_UI_FLAG_LAYOUT_STABLE)
                decorView.systemUiVisibility = option
            }
            //让view空出状态栏高度
            val resourceId =
                resources.getIdentifier("status_bar_height", "dimen", "android")
            if (resourceId > 0) {
                var statusBarHeight = resources.getDimensionPixelSize(resourceId)
                binding.root.setPadding(0, statusBarHeight, 0, 0)
            }
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
            window.setStatusBarColor(Color.TRANSPARENT)
            //导航栏颜色也可以正常设置
            //window.setNavigationBarColor(Color.TRANSPARENT);
        }
    }
