安卓隐藏状态栏和导航栏

• 参考代码
• 设置了 FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS 表明 Window 负责系统 bar 的 background 绘制，绘制透明背景的系统 bar（状态栏和导航栏）

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {val insetsController = this.window.insetsController// 隐藏状态栏insetsController?.hide(WindowInsets.Type.statusBars())// 隐藏导航栏insetsController?.hide(WindowInsets.Type.navigationBars())// 隐藏标题栏supportActionBar?.hide()// 设置状态栏是透明的this.window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)// 设置导航栏是透明的this.window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION)this.window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)// 解决隐藏状态栏时，顶部出现黑长条问题，该属性可以让布局内容延伸到状态栏显示this.window.attributes.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES} else {this.window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)this.window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_NAVIGATION)this.window.setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN)this.window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)}

• 配合onWindowFocusChanged效果更加，可以实现状态栏和导航栏在触摸的时候出现而后自动隐藏

override fun onWindowFocusChanged(hasFocus: Boolean) {super.onWindowFocusChanged(hasFocus)// 判断是否有焦点if (hasFocus && Build.VERSION.SDK_INT >= Build.VERSION_CODES.R) {val decorView = window.decorViewdecorView.setSystemUiVisibility(android.view.View.SYSTEM_UI_FLAG_LAYOUT_STABLEor android.view.View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY)}}
