    Suppose in out text/paragraph of textview, some words are clickable or hyperlinked. In case you have a task to open those hyperlinked text in a webview of any browser you have to use SpannableStringBuilder. Below code with details will help you to open those specific hyperlinked words which are appearing on textview.

    // storing data into a string object
    String text=pagesPostDetail.getPOST().getPost_detail();
    // reading html text if any        
    CharSequence sequence = Html.fromHtml(text);
    // creating object of SpannableStringBuilder class
    SpannableStringBuilder strBuilder = new SpannableStringBuilder(sequence);
    UnderlineSpan[] underlines = strBuilder.getSpans(0, 10, UnderlineSpan.class);
    // now searching underlines text from start to end 
    for(UnderlineSpan span : underlines) {
        int start = strBuilder.getSpanStart(span);
        int end = strBuilder.getSpanEnd(span);
        int flags = strBuilder.getSpanFlags(span);
        ClickableSpan myActivityLauncher = new ClickableSpan() {
              public void onClick(View view) {
    	       // ACTION_VIEW to open intent webview chooser
                   Intent intent = new Intent(Intent.ACTION_VIEW, Uri.parse(text));
                   context.startActivity(intent);
                   }
              };
        strBuilder.setSpan(myActivityLauncher, start, end, flags);
        }
    // finally attaching to the textview
    post_detail_Textview.setText(strBuilder);
    post_detail_Textview.setLinksClickable(true);
    post_detail_Textview.setMovementMethod(LinkMovementMethod.getInstance());
