android - 使 ModalBottomSheetLayout 始终展开

Question

我正在使用 ModalBottomSheetLayout在 Jetpack Compose 中。每当它显示为 modalBottomSheetState.show() ，它显示 HalfExpanded或 Expanded取决于其内容的高度。这是来自源代码:

val anchors = if (sheetHeight < fullHeight / 2) {
        mapOf(
            fullHeight to Hidden,
            fullHeight - sheetHeight to Expanded
        )
    } else {
        mapOf(
            fullHeight to Hidden,
            fullHeight / 2 to HalfExpanded,
            max(0f, fullHeight - sheetHeight) to Expanded
        )
    }
    Modifier.swipeable(
        state = sheetState,
        anchors = anchors,
        orientation = Orientation.Vertical,
        enabled = sheetState.currentValue != Hidden,
        resistance = null
    )

然后 show()像这里一样工作:

 internal val isHalfExpandedEnabled: Boolean
    get() = anchors.values.contains(HalfExpanded)

/**
 * Show the bottom sheet with animation and suspend until it's shown. If half expand is
 * enabled, the bottom sheet will be half expanded. Otherwise it will be fully expanded.
 *
 * @throws [CancellationException] if the animation is interrupted
 */
suspend fun show() {
    val targetValue =
        if (isHalfExpandedEnabled) HalfExpanded
        else Expanded
    animateTo(targetValue = targetValue)
}

我想知道我们是否可以将其设置为始终 Expanded不知何故

您可以使用:

scope.launch { state.animateTo(ModalBottomSheetValue.Expanded) }

代替

scope.launch { state.show() }
