Android 正则表达式 匹配 (数字)x(数字)

Java

// 匹配 (数字)x(数字) 格式的字符串
String mPattern = "(\\d+)(x|X)(\\d+)";
Pattern r = Pattern.compile(mPattern);
Matcher m = r.matcher(chosedFile);
if (m.find()) {
    try {
        // 得到两个数字的值
        int x= Integer.parseInt(m.group(1));
        int y= Integer.parseInt(m.group(3));
    } catch (NumberFormatException e) {
        e.printStackTrace();
    }
}
