Android Question convert string to number

[b4anewbie]

hi guys
I just got a problem . I need to convert an edittext string into a number so as to use for a calculation .
I have tried the following :
Dim i AsInt
i = EditText.Text + 1

but unfortunately it doesn't work at all !

please someone tell me how to do that . in vb we do sth like this :
Val(sting)

but I don't know how it is done in B4A . by the way , I've searched allover the forum but nothing found !

Thanks in advance

Your code is correct. The compiler will convert the string automatically.
However you should use IsNumber to make sure that the text is actually a valid number:

If IsNumber(EditText.Text) Then
 Dim i As Int = EditText.Text + 1
End If

You can include this function is yout favorite module (utils).

public Sub Val(Txt As String) As Double
If IsNumber(Txt) Then
Return Txt
Else
Return 0
End If
End Sub


And you can replace txt by txt.replace(",",".") or similar in evaluated code.
