java - Format Price in 0.00 format in android using edittext -

i trying mask price value in 0.00 format. here code

float temp = 0;  decimalformat mdecimalformat = new decimalformat("###.00");  @override public void ontextchanged(charsequence s, int start, int before, int count) {      if(s.tostring()!=null)     {          mmasedittext.removetextchangedlistener(this);         temp = float.parsefloat(s.tostring());         mmasedittext.settext(""+mdecimalformat.format(addnumber(temp)));         mmasedittext.setselection(start+1);         mmasedittext.addtextchangedlistener(this);      } }  public float addnumber(float numtemp){     float result=0.00f;     result = numtemp + result;     return result; } 

but when pressing decimal, want cursor go 1 more step. not able dot callback. when pressing button, remove digits, index out of bound exception. can tell me how button , dot button callback before ontextchanged listener?

recommended way of formatting currency , prices:

    locale loc = locale.getdefault();     numberformat nf = numberformat.getcurrencyinstance(loc);     nf.setcurrency(currency.getinstance(loc));     nf.setmaximumfractiondigits(2);     nf.setminimumfractiondigits(2);      system.out.println(nf.format(23.5634));     system.out.println(nf.format(0.5));
