Make specific substring of SpannableString editable

Question

Im trying to make certain substrings of a SpannableString editable.

Im able to identify and make clickable any substring that matches my criteria using matcher.find() and ClickableSpan()

Im also able to make the substring editable using

myTxtView.setFocusable(true);
myTxtView.setEnabled(true);
myTxtView.setClickable(true);
myTxtView.setFocusableInTouchMode(true);
myTxtView.setCursorVisible(true);
myTxtView.setInputType(InputType.TYPE_CLASS_TEXT);
myTxtView.requestFocus();

The problem is the entire textview becomes editable, not just the substrings that where matched.

Here is the code

final SpannableString hashText = new SpannableString(myTxtView.getText().toString());

while (matcher2.find()) {

  //find and match strings

  hashText.setSpan(new ClickableSpan() {

    @Override
    public void onClick(View widget) {

    //do something on click       

    }

    @Override
    public void updateDrawState(TextPaint ds) {
      super.updateDrawState(ds);
      ds.setColor(Color.parseColor("#A8000000"));
      ds.setUnderlineText(true);

    }

  },matcher2.start(),matcher2.end(),1);

}
  myTxtView.setText(hashText);
  myTxtVIew.setMovementMethod(LinkMovementMethod.getInstance());
  myTxtView.setFocusable(true);
  myTxtView.setEnabled(true);
  myTxtView.setClickable(true);
  myTxtView.setFocusableInTouchMode(true);
  myTxtView.setCursorVisible(true);
  myTxtView.setInputType(InputType.TYPE_CLASS_TEXT);
  myTxtView.setInputType(InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

I've played around a bit with Editable.Factory() with no success. Not sure how or if that is applicable to my case.

You need to use ClickableSpan to perform the things you want, here is some codeSnippet which will help you

SpannableString spanString = new SpannableString(text);
    Matcher matcher = Pattern.compile("@([A-Za-z0-9_-]+)").matcher(spanString);

    while (matcher.find())
    {
        spanString.setSpan(new ForegroundColorSpan(Color.parseColor("#0000FF")), matcher.start(), matcher.end(), 0); //to highlight word havgin '@'
        final String tag = matcher.group(0);
        ClickableSpan clickableSpan = new ClickableSpan() {
            @Override
            public void onClick(View textView) {
                Log.e("click", "click " + tag);
                String searchText=tag.replace("@",""); //replace '@' with blank character to search on google.
                Intent browserIntent = new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.google.co.in/search?q=" + searchText));
                startActivity(browserIntent);
            }
            @Override
            public void updateDrawState(TextPaint ds) {
                super.updateDrawState(ds);

            }
        };
        spanString.setSpan(clickableSpan, matcher.start(), matcher.end(), Spanned.SPAN_EXCLUSIVE_EXCLUSIVE);
    }
