剪切区域中的操作栏裁剪

Question

当我使用全屏剪切时，我有下一个 屏幕。如何解决这个问题？

剪影：

window.attributes.layoutInDisplayCutoutMode = WindowManager.LayoutParams.LAYOUT_IN_DISPLAY_CUTOUT_MODE_SHORT_EDGES

全屏：

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {
if (visible) {
window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
)
} else {
window.decorView.systemUiVisibility = (View.SYSTEM_UI_FLAG_LAYOUT_STABLE
or View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION
or View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN
or View.SYSTEM_UI_FLAG_HIDE_NAVIGATION // прячем панель навигации
or View.SYSTEM_UI_FLAG_FULLSCREEN // прячем строку состояния
or View.SYSTEM_UI_FLAG_IMMERSIVE_STICKY)
}
}

透明

val color = ContextCompat.getColor(this, R.color.transparent_dark)
window.statusBarColor = color
window.navigationBarColor = color

默认情况下的操作栏(非自定义工具栏(：

<style name="AppTheme.Viewer" parent="Theme.AppCompat.Light.DarkActionBar">
<item name="windowActionModeOverlay">true</item>
<item name="actionBarStyle">@style/MyTheme.ActionBar</item>
</style>
<style name="MyTheme.ActionBar" parent="Widget.AppCompat.ActionBar">
<item name="elevation" tools:targetApi="lollipop">0dp</item>
<item name="background">@color/transparent_dark</item>
</style>

谷歌没有帮助我。

默认情况下，操作栏处理 WindowInset 并在系统元素应该位于的位置添加填充(状态栏、导航栏和剪切像我一样(。 如果将操作栏添加到布局中，则可以自行决定如何处理窗口插图。

themedAppBarLayout(R.style.MyTheme_Viewer_ActionBarOverlay) {
id = Id.toolbar
backgroundColorResource = R.color.transparent_dark
doOnApplyWindowInstets { v, insets, _ ->
v.updateLayoutParams<ViewGroup.MarginLayoutParams> {
// Added indent only on top. 
// ActionBar takes up the entire width of the screen without indentation.
topMargin = insets.systemWindowInsetTop
// If there is a cutout, we get its dimensions
val cutoutRight = insets.displayCutout?.safeInsetRight ?: 0
val cutoutLeft = insets.displayCutout?.safeInsetLeft ?: 0
// Subtract the cutout size from WindowInsets, for fullscreen
rightMargin = insets.systemWindowInsetRight - cutoutRight
leftMargin = insets.systemWindowInsetLeft - cutoutLeft
}
insets
}
toolbar = toolbar {
lparams(width = matchParent, height = wrapContent)
}
}

fun View.doOnApplyWindowInstets(block: (View, WindowInsetsCompat, Rect) -> WindowInsetsCompat) {
val initialPadding = recordInitialPaddingForView(this)
ViewCompat.setOnApplyWindowInsetsListener(this) { v, insets ->
block(v, insets, initialPadding)
}
doFromSdk(20) {
requestApplyInsetsWhenAttached()
}
}

@RequiresApi(Build.VERSION_CODES.KITKAT_WATCH)
fun View.requestApplyInsetsWhenAttached() {
if (isAttachedToWindow) {
requestApplyInsets()
} else {
addOnAttachStateChangeListener(object : View.OnAttachStateChangeListener {
override fun onViewAttachedToWindow(v: View) {
v.removeOnAttachStateChangeListener(this)
v.requestApplyInsets()
}
override fun onViewDetachedFromWindow(v: View) = Unit
})
}
}

fun recordInitialPaddingForView(view: View) =
Rect(view.paddingLeft, view.paddingTop, view.paddingRight, view.paddingBottom)
