如何根据appbar自动给Android的状态栏着色

Question

根据应用栏的材质3规格，不仅应用栏本身，状态栏也应该在滚动应用栏下的列表时调整其颜色。如何实现这一目标？我们应该在每个屏幕中手动执行此操作吗？ https://m3.material.io/components/top-app-bar/guidelines

Answer 1

在您希望状态栏适应其颜色的每个屏幕中，您可以手动处理此行为。使用

WindowInsetsController

和

getWindowInsetsController()

方法。此方法从Android 11开始可用：

// Obtain an instance of the WindowInsetsController
val windowInsetsController = window?.insetsController

// Set the appearance of the system bars
windowInsetsController?.setSystemBarsAppearance(APPEARANCE_STABLE_TOP, APPEARANCE_STABLE_TOP)

// For example, you can listen to the scroll events and update the appearance flags accordingly
