问题描述

如何解析 Android 平板电脑的 /proc/cpuinfo 虚拟文件以获取处理器内核和时钟速度的信息?我不需要上述文件提供的所有信息；就这两个位.有人可以帮忙吗?

How can I parse /proc/cpuinfo virtual file of my Android tablet to get information of the processor's core and clockspeed? I don’t need all information provided by the above file; just these two bits. Can someone please help?

推荐答案

• 目前尚不清楚您是否希望在您的应用中使用这些信息，还是仅供您自己使用.

  • It is not clear if you want this information inside your app, or just for your own use.

    您可以使用 adb 获取此信息:

    you can get this information on with adb:

    adb shell cat /proc/cpuinfo
    

    如果你想在你的应用中使用这些信息，创建一个简单的函数来返回一个Map，例如，

    If you want to use this information in your app, create a simple function to return a Map<String,String>, for example,

    public static Map<String, String> getCpuInfoMap() {
        Map<String, String> map = new HashMap<String, String>();
        try {
            Scanner s = new Scanner(new File("/proc/cpuinfo"));
            while (s.hasNextLine()) {
                String[] vals = s.nextLine().split(": ");
                if (vals.length > 1) map.put(vals[0].trim(), vals[1].trim());
            }
        } catch (Exception e) {Log.e("getCpuInfoMap",Log.getStackTraceString(e));}
        return map;
    }
    

    注意，这不会得到多个cpus信息，会覆盖.无论如何，大多数值都是相似的.或修改以创建 CpuInfoMap 列表.

    Note, this will not get multiple cpus information, overwrites. Most of the values are similar anyways. or Modify to create List of CpuInfoMaps.

    试试，

    Log.d("getCpuInfoMap test", getCpuInfoMap().toString());
