How to format edittext (android) -

i need format edittext add dot.

when input more 3 numbers put dot after first number (like this: 1.000)

but when input have more 4 numbers put dot after second number (like this: 10.000)

i tried addtextchangedlistener didn't work.

this algorithm add numbers @ end , move dot, next example:

you have @ begining 0.00 insert 1 , have 0.01 insert 5 , have 0.15 insert 9 , have 1.59

try modified code , adapt need.

youtedittext.addtextchangedlistener( new textwatcher() {             boolean mediting = false;              public void ontextchanged(charsequence s, int start, int before, int count) { }              public void beforetextchanged(charsequence s, int start, int count, int after) { }              public void aftertextchanged(editable s) {                 if(!mediting) {                     mediting = true;                     string digits = s.tostring().replaceall("\\d", "");                     numberformat nf = new decimalformat( "#,##0.00" );                     try{                         string formatted = nf.format(double.parsedouble(digits)/100);                         s.replace(0, s.length(), formatted);                     } catch (numberformatexception nfe) {                         s.clear();                     }                     mediting = false;                 }             }         }); 

other thing need put focus @ end of text, can next code:

youredittext.setonfocuschangelistener(new view.onfocuschangelistener() {             @override             public void onfocuschange(view v, boolean hasfocus) {                 if(hasfocus){                     amount.setselection(amount.gettext().length());                 }             }         });  

i hope can you.
