Android 状态栏透明实现

如一下代码

 if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) {
            //5.0 透明
            //getWindow.setStatusBarColor(Color.TRANSPARENT)
            val window = window
            window.clearFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
            window.decorView.systemUiVisibility = View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN or View.SYSTEM_UI_FLAG_LAYOUT_STABLE
            window.addFlags(WindowManager.LayoutParams.FLAG_DRAWS_SYSTEM_BAR_BACKGROUNDS)
            window.statusBarColor = Color.TRANSPARENT
        } else if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
            //4.4 透明
            window.addFlags(WindowManager.LayoutParams.FLAG_TRANSLUCENT_STATUS)
        }
