pls try this.
To handle the case that more than one character is inserted (e.g. copy and
paste, click a text editor) and less than one character is inserted (e.g.
delete text, e.text="")
public void verifyText(VerifyEvent e) {
boolean result=true;
if (e.text.length()==1){
result = "0123456789.".indexOf(e.text) >= 0 ;
}
e.doit = result;
}
