Question

I need to extract only numeric values ​​from String str="sdfvsdf68fsdfsf8999fsdf09" . How can I extract numbers from an alpha numeric string in android?

Answer 1

 String str="sdfvsdf68fsdfsf8999fsdf09"; String numberOnly= str.replaceAll("[^0-9]", ""); 

update:

 String str="fgdfg12°59'50\" Nfr | gdfg: 80°15'25\" Efgd"; String[] spitStr= str.split("\\|"); String numberOne= spitStr[0].replaceAll("[^0-9]", ""); String numberSecond= spitStr[1].replaceAll("[^0-9]", ""); 

Answer 2

 public static String getOnlyNumerics(String str) { if (str == null) { return null; } StringBuffer strBuff = new StringBuffer(); char c; for (int i = 0; i < str.length() ; i++) { c = str.charAt(i); if (Character.isDigit(c)) { strBuff.append(c); } } return strBuff.toString(); } 

Answer 3

 public static int extractNumberFromAnyAlphaNumeric(String alphaNumeric) { alphaNumeric = alphaNumeric.length() > 0 ? alphaNumeric.replaceAll("\\D+", "") : ""; int num = alphaNumeric.length() > 0 ? Integer.parseInt(alphaNumeric) : 0; // or -1 return num; } 

You can set the value to 0 or -1 (what to do if there is no number at all in the alphanumeric format) according to your needs
