Question

我知道这是一个容易的话题，但我总是得到错误..我从xml文件中获取数据包含的字符串，如262626我试图将此字符串转换为MB（/ 1024）表单。但它没有转换为int或long可以有人帮助我吗？

这是我测试的内容

String size = parser.getValue(e, parser.KEY_FileSizeInByte);
Log.i("menuItems",size);

    try {
        int s = Integer.parseInt(size);
        Log.i("s", getString(s));
    }
    catch (Exception e1) {
        Log.i("error", e1.getMessage());
    }

我也测试了

Integer.valueOf(str);

这是我收到的错误：

Answer 1

这是你的日志错误。这里：

Log.i("s", getString(s));

那是尝试使用给定的标识符获取资源。你只想要：

Log.i("s", String.valueOf(s));

为什么我不能将String转换为Integer
