commit c60f33e229e31ab328ef6b59dab63b264954831c

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() }'."

Waiting for an official one, you can use this composable function; It is performance optimized:

AutoSize: Create API

See design doc go/autosize

Test: Tested equals(), checked that the stepBased implementation was falling back to minFontSize = maxFontSize if minFontSize > maxFontSize and throwing IllegalArgumentExceptions with all other potential combinations of illegal arguments, checked if getFontSize() acts as intended including edge cases like when overflow always and never occurs.

AutoSize: Implement ParagraphLayoutCache logic

Also add autoSize parameter to TextAnnotatedStringElement and TextAnnotatedStringNode

Test: Checked valid and invalid sequences of font sizes, different constraints, different texts, Ellipsis/Visual overflow behavior, compatibility with the em unit and behavior when minLines is greater than 1. All works as intended.

Publish AutoSize Text

AutoSize is now public and sealed and does not expose any API. All methods are moved to the internal TextAutoSize, which will let us publish the API for custom AutoSize implementations in the future if needed.

Test: Existing
Bug: 139320827
Relnote: "Support for auto-sizing text. Pass an AutoSize instance (e.g. AutoSize.StepBased) to your favorite text composable (like BasicText) and see your text size adapt to the available space!"

Hello, out of curiosity, is is something for compose 1.8 or later?

jo...@google.com <jo...@google.com> #13Oct 29, 2024 07:46AM

This will land in 1.8, pending possible API refinements. We will comment on this issue when the change is included in a release.

pr...@google.com <pr...@google.com> #14Oct 30, 2024 05:38PM

The following release(s) address this bug.It is possible this bug has only been partially addressed:

androidx.compose.foundation:foundation:1.8.0-alpha05
androidx.compose.foundation:foundation-android:1.8.0-alpha05
androidx.compose.foundation:foundation-jvmstubs:1.8.0-alpha05
androidx.compose.foundation:foundation-linuxx64stubs:1.8.0-alpha05

an...@justdice.io <an...@justdice.io> #15Nov 1, 2024 10:59AM

I tested out androidx.compose.foundation:foundation:1.8.0-alpha05 and noticed that BasicText with an autoSize argument just cuts off the text with maxLines set to 1.

On Android Views, when using android:autoSizeTextType="uniform" and android:maxLines="1", the TextView properly sizes down until the min text size is reached.

<LinearLayout
        android:layout_width="15dp"
        android:layout_height="wrap_content">
        <TextView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:autoSizeTextType="uniform"
            android:autoSizeMinTextSize="2sp"
            android:autoSizeMaxTextSize="14sp"
            android:maxLines="1"
            android:text="Test" />
</LinearLayout>

Box(Modifier.width(15.dp)) {
        BasicText("Test", autoSize = AutoSize.StepBased(2.sp, 14.sp), maxLines = 1)
}
