HTML formatting in Android's new data binding library

Question

Using the new data binding library of Android, can I use HTML formatting for TextView through XML only or do I have to use Html.fromHtml programmatically?

Answer 1

You must import Html and then call the fromHtml method :

<data>
    <import type="android.text.Html"/>
</data>
…
<TextView
    android:text="@{Html.fromHtml(@string/my_html)}"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"/>

Answer 2

In case if you want to use string with html tags and combine it with string parameters, it could be done in a such way:

In layout:

<TextView
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@{activity.formattedString}" />

In your activity (for ex):

public CharSequence getFormattedString() {
    if(selectedItem == null) return null;
    String str = String.format(Html.toHtml(SpannedString.valueOf(this.getResources().getText(R.string.your_tagged_string))), parameter);
    return Html.fromHtml(str);
}
