What's the equal of textView.setText( (Html.fromHtml(htmlString , Html.FROM_HTML_MODE_LEGACY))); in compose?

html parsing to AnnotatedString is not implemented. There are samples for building AnnotatedStrings here https://cs.android.com/androidx/platform/frameworks/support/+/androidx-master-dev:ui/ui-text-core/samples/src/main/java/androidx/ui/text/samples/AnnotatedStringBuilderSamples.kt;l=125 and android's stock html -> spanned implementation is here https://cs.android.com/android/platform/superproject/+/master:frameworks/base/core/java/android/text/Html.java;l=1?q=Html.java&sq=&ss=android

Habib, have you made progress toward this? I'm also need to do this, but I've been putting it off.

[Kazemihabib1996]

No actually I asked this out of curiosity as I couldn't find any API for that when I've been studying AnnotatedStrings

[Kazemihabib1996]

I needed that for a Bullet thenI found

with(DensityAmbient.current) {
            // this box is acting as a character, so it's sized with font scaling (sp)
            Box(
                modifier = Modifier
                    .preferredSize(8.sp.toDp(), 8.sp.toDp())
                    .alignWithSiblings {
                        // Add an alignment "baseline" 1sp below the bottom of the circle
                        9.sp.toIntPx()
                    },
                backgroundColor = contentColor(),
                shape = CircleShape
            )
        }

in JetNews sample.

I see. I'm looking into the possibility of converting a SpannedString to an AnnotatedString

[pardom]

Then you can use it more generically, e.g. for Html.fromHtml or https://github.com/noties/Markwon

[pardom]

Doesn't look like AnnotatedString has an equivalent of ClickableSpan. It appears you can only style text.

[Adam Powell]

A SpannedString to AnnotatedString is going to be a lossy conversion, AnnotatedString is deliberately less open-ended to avoid a bunch of issues we had with SpannedString

[pardom]

Yeah, SpannedString is very open-ended 😆 I used it to implement Slack style tokenization once, which was neat, but felt unnerving considering the lack of an interface for spans.

[Adam Powell]

not to mention the troubles that happen as soon as you want to parcel it.
