我的edittext能够过滤虚拟键盘上的字符和数字但不占用空格字符..请帮助

Answer 1

而不是'||' 我用'&&'替换并得到了答案....

Answer 2

!Character.isLetterOrDigit(source.charAt(i)) || Character.isSpaceChar(source.charAt(i))

是您想要的代码，假设您不想要空格字符并且只想要数字或字符。

Answer 3

使用这个条件

for (int i = start; i < end; i++) { 
    if (!Character.isLetterOrDigit(source.charAt(i))) {
        if (!Character.isSpaceChar(source.charAt(i)))
            return "";
    }
}
