Answer 1

不确定它是否对您有帮助。您可以尝试使用正则表达式，也可以在此处添加其他特殊字符。

boolean result = yourString.contains("[-+.^:,]");

Answer 2

使用此方法检查特殊字符：

    Pattern p = Pattern.compile("[&%$#@!()*^]"); //<---- you can add more characters to check here 
    Matcher m = p.matcher(myEditText2);
    if (m.find()) {
        editText.setError("you can not enter special Character");
        return false;
    }

导入这些包：

import java.util.regex.Matcher;
import java.util.regex.Pattern;
