Html.fromHtml in DataBinding - Android

I think that the view should not have any logic/transformation to display the data. What I'd recommend to do is creating a BindingAdapter for this:

@BindingAdapter({"android:htmlText"})
public static void setHtmlTextValue(TextView textView, String htmlText) {
    if (htmlText == null)
        return;

    Spanned result;
    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
        result = Html.fromHtml(htmlText, Html.FROM_HTML_MODE_LEGACY);
    } else {
        result = Html.fromHtml(htmlText);
    }
    textView.setText(result);
}

Then within the layout call it as usual:

<TextView
                android:id="@+id/bid_footer"
                style="@style/MyApp.TextView.Footer"
                android:htmlText="@{viewModel.bidFooter} />

Where viewModel.bidFooter has the logic to get the String/Spanned/Chars with the text, taking into consideration not having any direct dependence to context, activity, etc

Think you need to import html first in the xml

<data>
    <import type="android.text.Html"/>
</data>

<TextView
    android:id="@+id/txtDateCreate"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@{Html.fromHtml(String.format(@string/DateCreate,others.created))}" />

The line below is deprecated in Android N (API level 24).

Html.fromHtml(content)

Now you're supposed to provide two params (content and flag) like below:

Html.fromHtml(content, HtmlCompat.FROM_HTML_MODE_LEGACY)

So I'll suggest you use @BindingAdapter like below:

object BindingUtils {

@JvmStatic
@BindingAdapter("loadHtml")
fun loadHtml(textView: TextView, content: String?){
    if (!content.isNullOrEmpty()) {
        textView.text = if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
            Html.fromHtml(content, HtmlCompat.FROM_HTML_MODE_LEGACY)
        } else {
            Html.fromHtml(content)
        }
    }
}

}

and in your XML file:

 <data>
    <import type="com.example.utils.BindingUtils"/>
</data>
<TextView
        android:id="@+id/textView"
        android:layout_width="0dp"
        android:layout_height="wrap_content"
        app:loadHtml="@{String.format(@string/DateCreate,others.created))}"/>
