How to replace these characters "[" and "]" using regex?

Question

I have a string like this

String myString = "I love [stackoverflow]";

What I want to do is to replace the character "[" to <span style="color:red;"> and the character "]" to </span> to change the color of the word stackoverflow to red.

So the expected string result is "I love <span style="color:red;">stackoverflow</span>"

I am new in regex so I tried like this

String myString = "I love [Stackoverflow]";

myString.replaceAll("[",<span style="color:red;">).replaceAll("]","</span>");

but seems not the correct way because the android studio says

unclosed character class

What is the correct regex of that single character?

Don't use `replaceAll` since you're not even using regex. Use: `myString.replace("[",).replace("]","");` — anubhava, Jul 27 '19 at 10:08
I think this is the correct answer, I am a newbie in regex so I do not have an idea how regex works. — Noryn Basaya, Jul 27 '19 at 10:11

String myString = "I love [stackoverflow]";

    myString = myString.replace("[", "<b><font color=\"#FF0000\">").replace("]", "</font>");

    etEmail = (EditText) findViewById(R.id.et_email);
    etEmail.setText(Html.fromHtml(myString));
