Android EditText 验证和正则表达式

Question

我即将为 android 创建 editText 验证，我使用了 if..else 语句，但编码似乎不适用于我的应用程序...我想让所有字段都是强制性的，如果您将一个字段留空，您无法继续，我也对电话号码的验证感到好奇，因为我来自马来西亚，所以有效的电话号码是例如：0133999504，不允许使用“-”符号或任何字母..只有数字和“+”号有效..身份证号码也是一样，马来西亚的身份证号码就像身份证号码，我也想要“-”符号不允许只有字母和数字才有效.. 发生错误时如何使editText框边框突出显示？..下面是我的完整编码..有什么想法或解决方案吗？
