TextField

[onestep]

If You want to make a TextField with calculator
(only adding and 1 number, if you press on 5 it
show 5 then 6 it show 11 then 3 it show 14 aso)
and then use this code

int oldnumber =0;

public void itemStateChanged(Item item){
if (item instanceof TextField){
TextField text=(TextField)item;
int newNumber=oldNumber+Integer.parseInt(text.getString().substring(text.getString().length()-1,text.getString().length()));
oldnumber=newnumber;
text.setString(""+newNumber);
so works it with Suns emulator but not in Nokia 6630. Why?

Hello onestep,

and welcome to Forum Nokia Discussion Boards!

so works it with Suns emulator but not in Nokia 6630. Why?

What happens with Nokia 6630?

nothing happens it only shows 0, but it must be the code
int newNumber=oldNumber+Integer.parseInt(text.getString().substring(text.getString().length()-1,text.getString().length()));
that the phone dont accept.

public void itemStateChanged(Item item){
if (item instanceof TextField){
TextField text=(TextField)item;
int newNumber=oldNumber+Integer.parseInt(text.getString().substring(text.getString().length()-1,text.getString().length()));
oldnumber=newnumber;
text.setString(""+newNumber);

Hey do one thing, draw the value of the oldnumber using the form.append(""+oldnumber);just for the testing.
And paint the output on the console after oldnumber=newnumber; and before this line.Check and let's us know the results.

With form.append(""+oldnumber) it only show 0 on the phone, but in the emulator it adds ok.
But I have this code for the TextField
public TextField getTextField() {
if (textField == null) {

textField = new TextField("tf", null, 32, TextField.NUMERIC);
textField.setString(""+0);
}
return textField;
}
and if I take +0 away from the textField.setString(""+0); the phone works but only with one number, if I add nr 1 it show 1 but when I add next number it shows 2 and that do it if I add nr5,nr0 or all the numbers.The phone has his own loop
This loop
Nr1 1+1+2+4+8+6+2+4+8+6 aso
Nr2 2+2+4+8+6+2+4+8 aso
Nr3 3+3+6+2+4+8+6+2 aso
Nr4 4+4+8+6+2+4+8+6 aso
Nr5 5+5+0+0+0 aso
Nr6 6+6+2+4+8+6 same loop as nr 1, Nr7 start with two 7 and then the same loop as nr 2
Nr8 has Nr3s loop and number nr 9 has nr 4s loop, if I start adding with a zero it shows only 0 and it is no matter which number I add.

I try with form.append(""+oldnumber) and textField.setString("");
and it show exact the same loops.

Is it only Nokia 6630 which behave so strange.
if I change
int newNumber=oldNumber+Integer.parseInt(text.getString().substring(text.getString().length()-1,text.getString().length()));
oldnumber=newnumber;
text.setString(""+newNumber);
to
int newNumber=Integer.parseInt(text.getString().substring(text.getString().length()-1,text.getString().length()));
int ANumber=newNumber;
int BNumber=ANumber+oldNumber;
oldnumber=BNumber;
text.setString(""+BNumber);
so works it in the emulator but in the phone its the same strange loops.
but if I change to
int ANumber=newNumber*0+1;
then it adds +1 both in the emulator and in the phone.
