I make a simple client tweeter and run into a problem. In the tweet text there are mentions about the user, for example: @ user98 how to make it stand out in the text and be clickable?

    You need to use the Spannable interface. It is intended for styling text. For example:

    enter image description here

    Adding marking is carried out by the method:

    Spannable.setSpan(Object span, int start, int end, int flags);

    Deletion, respectively, by the method:

     Spannable.removeSpan(Object span);

    Text selection example:

     // Create spannable text and set style. Spannable text = new SpannableString("This is underline and bold text."); text.setSpan(new UnderlineSpan(), 8, 17, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); text.setSpan(new StyleSpan(Typeface.BOLD), 22, 26, Spanned.SPAN_EXCLUSIVE_EXCLUSIVE); // Set spannable text in TextView. TextView textView = (TextView) findViewById(R.id.text); textView.setText(text);

    Here is a good article on this topic in Russian - http://developer.alexanderklimov.ru/android/theory/spannable.php

    • For clickability, appropriately, ClickableSpan along with UnderlineSpan and / or with other spans. - Andrew Grow
