问题描述

I want to check the 10 digit phone number whether all 10 digits are same or different. If same means Invalid mobile number alert will be displayed. I want a code in LWUIT.

推荐答案

将TextField的最大大小设置为10.它仅允许10位数字.还要将数字约束设置为该TextField.它仅允许数字值.查看示例代码，

set the TextField max size to 10. It allows only 10 digits. Also set the numeric constraint to that TextField. It allows only numeric value. See the sample code,

TextField txtf = new TextField();
txtf.setConstraint(TextField.NUMERIC);
txtf.setInputModeOrder(new String[] {"123"});
txtf.setMaxSize(10);
form.addComponent(txtf);

还要检查TextField中文本的长度.如果长度不是10位数，则可以显示警报.

Also check the length of the text in TextField. If length isn't 10 digit, you can showing the alert.

要检查重复的数字，请使用 addDataChangeListener .您可以在此侦听器内部处理验证.

For checking repeated numbers, Use addDataChangeListener. You can handle the validation inside of this listener.
