Is there possibility in android to provide TextView some text in Java code with setText(text) function with basic tags like and to make marked words underlined ?
You can use UnderlineSpan from SpannableString class:
SpannableString content = new SpannableString(); content.setSpan(new UnderlineSpan(), 0, content.length(), 0);
Then just use textView.setText(content);
textView.setText(content);
