Android中获取手机设备信息、RAM、ROM存储信息，如宽、高、厂商名、手机品牌

借鉴：https://www.jianshu.com/p/ca869aa2fd72

今天有两个工具类总结，代码里都有注释，直接看代码。

一、首先第一个，主要获取手机设备信息DeviceInfoUtils。

  1. public class DeviceInfoUtils {
  2.  
  3.     /**
  4.      * 获取当前手机系统语言。
  5.      *
  6.      * @return 返回当前系统语言。例如：当前设置的是“中文-中国”，则返回“zh-CN”
  7.      */
  8.     public static String getSystemLanguage() {
  9.         return Locale.getDefault().getLanguage();
  10.     }
  11.  
  12.     /**
  13.      * 获取当前系统上的语言列表(Locale列表)
  14.      */
  15.     public static Locale[] getSystemLanguageList() {
  16.         return Locale.getAvailableLocales();
  17.     }
  18.  
  19.     /**
  20.      * 获取当前手机系统版本号
  21.      */
  22.     public static String getSystemVersion() {

  24.     }
  25.  
  26.     /**
  27.      * 获取手机型号

  29.     public static String getSystemModel() {

  31.     }
  32.  
  33.     /**
  34.      * 获取设备宽度（px）

  52.         TelephonyManager tm = (TelephonyManager) ctx.getSystemService(Activity.TELEPHONY_SERVICE);
  53.         if (tm != null) {
  54.             return tm.getDeviceId();

  56.         return null;
  57.     }
  58.

  121.     }
  122.  
  123.     /**
  124.      * 显示ID
  125.      */
  126.     public static String getDeviceDisplay() {
  127.         return Build.DISPLAY;
  128.     }
  129.  
  130.     /**
  131.      * ID
  132.      */
  133.     public static String getDeviceId() {

  186. }

二、第二个主要获取RAM、ROM存储信息SDCardUtils。

  1. public class SDCardUtils {
  2.  
  3.     private static final int INTERNAL_STORAGE = 0;
  4.     private static final int EXTERNAL_STORAGE = 1;
