I need to enter a mobile number in a edit field. I need to display the number in this format:
123-456-7890
For example: 1234567890 is my mobile number, while am entering this into the text field,
after the first 3 digits I need to place a '-', after the next 3 digits, I need to place another '-'.
If I enter 123 then automatically place '-' in text field, after 456 place another '-' ,no need of placing for the last 4 digits.
Seems similar to displaying text in currency format, but when getting text from that text field I need to get the actual mobile number without any '-' ("1234567890", not 123-456-7890)
Any ideas on how to do this?

Answer 1

Please try to add Listener on EditFiled and check length of entered phoneno ans set "-" at 3 and 7 position see following code may be help full.
editField.getEditField().setChangeListener(new FieldChangeListener() {
public void fieldChanged(Field field, int context) {
EditField sfield = (EditField)field;
String number = sfield.getText();
if (number.length() == 3 || number.length() == 7) {
setFormat(number);
}
}
});
add(editField);
Create follwoing method on mainscreen class
private void setFormat(String newPhoneNo){
editField.setText(newPhoneNo+"-");
}
Whenever you gettext form edit remove "-".

Please check this code,
public MyScreen()
{
setTitle("MyTitle");
final EditField ef = new EditField();
add(ef);
ef.setChangeListener(new FieldChangeListener()
{
public void fieldChanged(Field field, int context)
{
if (ef.getText().length() == 4 && !ef.getText().endsWith("-"))
{
ef.setText(""+ef.getText().substring(0,3)+"-"+ef.getText().charAt(3));
}
if (ef.getText().length() == 8 && !ef.getText().endsWith("-"))
{
ef.setText(""+ef.getText().substring(0,7)+"-"+ef.getText().charAt(7));
}
}
});
}

Try out by trying first the native TextField.PHONENUMBER constraint.
public void startApp()
{
mDisplay = Display.getDisplay(this);
mTextField = new TextField("Text Field Label:",null,MAXCHARS,TextField.PHONENUMBER);
mForm = new Form("MIDlet Developer Guide: Display a text field.");
mForm.append(mTextField);
mDisplay.setCurrent(mForm);
}
