String s = "10<sup>12 </sup>";
textView.setText(Html.fromHtml(s)); // 12 will cropped 
// solution:
s = "10<sup>12 </sup>\t	"; // add behind ending of sup tag the tabulator \t, 
// but not char \t but only press to TAB key!!! in source code
textView.setText(Html.fromHtml(s)); // 12 is visible correctly
