created issue #1

Mar 29, 2021 03:57PM

Compose version: 1.0.0-beta03

Steps to reproduce:

Run application with Demo composable
Tap/click on the Snackbar's background

Actual behavior: Box behind receives input events (we can see a ripple effect)

Expected behavior: Box behind doesn't receive input events

@Composable
fun Demo() {
    val scaffoldState = rememberScaffoldState()
    LaunchedEffect(Unit) {
        scaffoldState.snackbarHostState.showSnackbar(
            message = "Are you sure you want to uninstall the tool?",
            actionLabel = "Yes",
            duration = SnackbarDuration.Indefinite
        )
    }
    MaterialTheme {
        Scaffold(
            scaffoldState = scaffoldState,
            snackbarHost = {
                SnackbarHost(
                    it,
//                    Modifier.pointerInput(Unit) { detectTapGestures {  } }
                ) { data ->
                    Snackbar(
                        snackbarData = data,
                        actionOnNewLine = true
                    )
                }
            }
        ) {
            Box(Modifier.fillMaxSize().background(Color.Blue).clickable { })
        }
    }
}

commit c60f33e229e31ab328ef6b59dab63b264954831c
Author: Alexandre Elias <aelias@google.com>

Semantics no-op cleanups

Partly in response to lmr's broad code review, I did a pass of
superficial API/implementation cleanup. The main changes are:

- I changed each Boolean SemanticsProperty where false is equivalent to
not being present to take "Unit" instead. This is conceptually
clearer: it avoids questions like "can I cancel out a semantics from a
merged child by setting it to false?" Because "property = Unit" looks
weird, I also changed the style of these to "property()".

- I moved the Semantics id generator closer to where it's used, in
SemanticsModifierCore. I made it internal and an AtomicInt.
(Note that integer ids are heavily used in the Android
AccessibilityNodeInfo APIs so I can't simply remove them entirely.)

- I deleted dead code. Some examples include SemanticsHintOverrides,
a public API not connected to anything, and SemanticsPropertyKey
merge() open method which is never called. (In both cases I have
a different plan in mind for accessibility.)

Fixes: 145951226
Fixes: 145955412
Test: existing tests
Relnote: "Single-value semantics properties now use a calling style.
For example, 'semantics { hidden = true }' is now written as:
'semantics { hidden() }'."

commit dfbfcd90a67d66d7eab8a7381e85ae9f831cea4a
Author: Matvei Malkov <malkov@google.com>
Date: Wed Mar 31 17:25:02 2021

Add experimental support for a version of Surface that handles click and make a regular Surface to block touches behind it.

Clickable Surface allows us to handle many issues at once:
1. Allows to define clicks on the Surface layout node, making a11y to be correct
2. Allows to define clicks in the single layout node without the need to transfer indication hnadling to the node below (because of the clipping inside the surface)
3. Allows for a desired default behaviour in a non-clickable Surface when we block pointer events from going under the surface. Throughout the many components it is seens like a desiged behaviour and often leads to bugs (snackbar, Drawer, modal sheet & card being norable examples of surfaces that shouldn't allow touches behind it).

To make this work properly, I refactored ModalBottomSheetLayout to work with the sheet-based swipeable (instead of content-based), since sheet is not blocking clicks.

With this one overload we solve many issues so it seems like a worthy experiment.
Relnote: BEHAVIOUR-BREAKING: Surface now consumes clicks, making clicks added via Surface(Modifier.clickable) to be a no-op. Please, use new experimental overload of Surface that accepts onClick.
Relnote: Added a new Surface overload that handles clicks as well as other clickable functionality: indication, interactionSource, enabled/disabled. It wasn't possible to use a regular non-clickable Surface with the Modifier.clickable because the Surface will not clip the ripple indication in those cases.
Test: Added new for an overload
