EditText field in Android to corectly format -

-

as title asks, want correctly monitor edit text field format entered numbers currency "." being l=placed or inserted after last 3 digits of cell.

in user inputs numbers , field expands edittext reflect numbers entered reflect currency, example below:

user enters "123456789"

the edittext reflect : "123.456.789"

any suggestions or comments welcome.

try this

edittext variablename = .... variablename.addtextchangedlistener(new textwatcher() {         @override         public void beforetextchanged(charsequence s, int start, int count, int after) {          }         @override         public void ontextchanged(charsequence s, int start, int before, int count) {          }         @override         public void aftertextchanged(editable s) {                             if(3 == s.length() % 4){                 s.append('.'); // change fire event again, careful, avoid infinite loops             }         }     });
