Android获取设备信息

试行2025-06-01 18:38

使用java:

bash 复制代码 
 List<TableMessage> dataList=new ArrayList<TableMessage>();
        //获取设备信息

        Hashtable<String,String> ht= MyDeviceInfo.getDeviceAllInfo2(LoginActivity.this);

        for (Map.Entry<String, String> entry : ht.entrySet()) {
            String key = entry.getKey();
            String value = entry.getValue();
            Log.d("Hashtable", "Key: " + key + ", Value: " + value);
            dataList.add(new TableMessage(key,value));
        }

       // String cpuABI = Build.CPU_ABI; // CPU架构（如arm64、x86）
        //int cpuCount = Runtime.getRuntime().availableProcessors(); // 逻辑核心数
//        String info = "架构：" + cpuABI + "+
//        核心数：" + cpuCount;
       // dataList.add(new TableMessage("核心数:",cpuCount+""));

        DialogTableDeviceInfo dialogTableDeviceInfo=new DialogTableDeviceInfo();

        dialogTableDeviceInfo.show(LoginActivity.this,"设备信息",dataList);
