Changing the color of only one world in a text view

Question

I am create an android app with android studio that retrieves text from mysqli database using volley library into a text view. I want to check if the text contains "@" and if to does it it should be coloured red. That Is, I want only the "@" to be changed. Please guys how will I achieve that?

Please show some work. Do you have code to get the text and display without colours? — Tomas By, Dec 07 '17 at 17:36

if text.contains("@") {
text.setTextColor(Color.RED);
}

I already did that but it changes all the texts in the text view. – Jude Dec 07 '17 at 18:02

This will change the color of only one word in this case "@"

Esto cambiara el color de una sola letra, en este caso "@"

String newText = String.valueOf(text.getText()).replace("@","<font color='#fff0000'>@</font>");
        text.setText(Html.fromHtml(newText));
