android - 删除 InteractionState 后，Jetpack Compose Beta 1 中提升按下状态

Question

在 compose-beta01 之前，使用 InteractionState 在 Jetpack Compose 中提升按下状态非常容易:

@Composable
fun App() {
    val interactionState = remember { InteractionState() }
    val pressed = interactionState.contains(Interaction.Pressed)

    MyComposable(Modifier.clickable(interactionState = interactionState) { })
}

InteractionState 在 beta01 中被删除，现在有明显的方法可以复制这种行为。如何使用 clickable 修饰符提升按下状态？

Answer 1

您是否尝试过应用Compose beta01发行说明中解释的内容？ ？

InteractionState has been replaced with [Mutable]InteractionSource

• Interfaces are responsible for emitting / collecting Interaction events.
• Instead of passing interactionState = remember { InteractionState() } to components such as Button and Modifier.clickable(), use interactionSource = remember { MutableInteractionSource() }.
• Instead of: Interaction.Pressed in interactionState you should instead use the extension functions on InteractionSource, such as InteractionSource.collectIsPressedAsState().
• For complex use cases you can use InteractionSource.interactions to observe the stream of Interactions. See the InteractionSource documentation and samples for more information.
• (I85965, b/152525426, b/171913923, b/171710801, b/174852378)

因此，在您的示例中，我会尝试以下操作:

val interactionSource = remember { MutableInteractionSource() }
val pressedState = interactionSource.collectIsPressedAsState()

MyComposable(
    Modifier.clickable(
        interactionSource = interactionSource,
        indication = LocalIndication.current
    ) {}
)
