[FIXED] How to make Textview will only show the last 4 digits numbers

Issue

My Textview is getting the data from SQLite, but I want to make Textview to show as follows:
************1234, instead of 1234123412341234.

enter image description here

Solution

    String number = "grou353fp23g3qprwog9512";
    String mask = number.replaceAll("\\w(?=\\w{4})", "*");

    textView.setText(mask);

Output is *******************9512
