processedMessageText can be mixed text with hyperlinks. So "test http://anysite.com" can't be directly converted to a link but the link has to be extracted and only this should be underlined and clickable.
Otherwise there could be a ActivityNotFoundException if the link is not valid.

to extract links, code from

talk-android/app/src/main/java/com/nextcloud/talk/chat/data/model/ChatMessage.kt

Line 167 in 7ca68b3

fun isLinkPreview(): Boolean {

will be helpful. This is the code which decides if the *LinkPreviewMessageViewHolder is applied.

However thinking about that there can be multiple links inside a message this gets more complicated. Then there might have to be more complex logic similar like it's used for the chip mentions:

talk-android/app/src/main/java/com/nextcloud/talk/utils/DisplayUtils.kt

Line 220 in 9d62a6f

fun searchAndReplaceWithMentionSpan(

link.setSpan(UnderlineSpan(), 0, link.length, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE)
binding.messageText.text = link

binding.messageText.setOnClickListener {
val browserIntent = Intent(Intent.ACTION_VIEW, Uri.parse(processedMessageText.toString()))
browserIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK)
context.startActivity(browserIntent)
}

removing
app:textAutoLink="all"
works and may be mandatory to fix the bug.

However this will change the behavior of all ChatMessage types and automatic link detection won't work as described in
