Is it possibile to use extension functions in databinding?

Question

I want to htmlize some data and set in the text view via data binding? Is it possible?

ie.If i have an extension function like this

 fun TextView.htmlText(txt: String?) {

txt.let {
    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
        Html.fromHtml(txt, Html.FROM_HTML_MODE_COMPACT)
    } else {
        Html.fromHtml(txt)
    }
 
}

}

how can i put this extension function in databinding instead of this android:text="@{model.text}"

Answer 1

I did it using binding adapter

 @BindingAdapter("app:text")
@JvmStatic
fun htmlText(view: TextView, text: String?) {
    text?.let {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.N) {
            view.text = Html.fromHtml(it.trim(), Html.FROM_HTML_MODE_COMPACT)
        } else {
            view.text = Html.fromHtml(it.trim())
        }
    }
}

like this.
