    You need to use Html.fromHtml() too. For example:

    AlertDialog.setMessage(Html.fromHtml("Hello "+"<b>"+"World"+"</b>"));

    Update:
    Looks like Html.fromHtml(String source) has been deprecated in the Latest Android Nougat version. Although deprecation doesn’t mean that you need to change your code now, but it’s a good practice to remove deprecated code from your app as soon as possible.
    The replacement is Html.fromHtml(String source, int flags). You just need to add an additional parameter mentioning a flag. 

    if (android.os.Build.VERSION.SDK_INT >= android.os.Build.VERSION_CODES.N) {
   AlertDialog.setMessage(Html.fromHtml("Hello "+"<b>"+"World"+"</b>", Html.FROM_HTML_MODE_LEGACY));
} else {
   @Suppress("DEPRECATION")
   AlertDialog.setMessage(Html.fromHtml("Hello "+"<b>"+"World"+"</b>"));
}

    For more details have a look at this answer.
