和你一起终身学习，这里是程序员Android

经典好文推荐，通过阅读本文，您将收获以下知识点:

一、获取手机基本信息(厂商、型号等参数)
二、设备信息获取实现图

八、DeviceInfoUtils 封装类
九、SDCardUtils 封装类

下面将讲解以上信息的获取方法。

一、 获取手机基本信息(厂商、型号等参数)

以小米手机为例，手机常用的基本信息可以在

Settings

–> 

About Phone

中看到，
例如下图：

小米手机设备信息图

那么如何获取这些设备信息呢？ 

Android

中 通常通过 

android.os.Build

类方法可以获取更多手机设备信息。

二、 设备信息获取实现图

获取手机IMEI、宽、高、是否有SD卡，RAM、ROM、SD卡、是否联网、网络类型

默认语言，设备名，型号、厂商、Fingerprint、Android 版本、SDK版本、Google 安全patch、发布时间、版本类型、用户名

产品名、ID、产品名、主板名

三、 获取手机设备 宽、高、IMEI 信息方法

获取手机宽、高、

IMEI

信息方法如下：

/*** 获取设备宽度（px）**/public static int getDeviceWidth(Context context) {return context.getResources().getDisplayMetrics().widthPixels;}/*** 获取设备高度（px）*/public static int getDeviceHeight(Context context) {return context.getResources().getDisplayMetrics().heightPixels;}/*** 获取设备的唯一标识， 需要 “android.permission.READ_Phone_STATE”权限*/public static String getIMEI(Context context) {TelephonyManager tm = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);String deviceId = tm.getDeviceId();if (deviceId == null) {return "UnKnown";} else {return deviceId;}}

注意：获取

IMEI

 需要获取手机状态权限

<!-- 读取手机IMEI的设备权限 --><uses-permission android:name="android.permission.READ_PHONE_STATE" />

如果是

Android 6.0

 之后的代码请使用动态申请权限的方法申请权限，否认会报安全异常的错误

SecurityException

，进而导致运行报错。

如需了解更多 系统安全权限的内容，请看 之前写的文章 Android 系统权限使用详解

四、 获取手机厂商名、产品名、手机品牌、手机型号、主板名、设备名的方法

获取手机厂商名、产品名、手机品牌、手机型号、主板名、设备名的方法如下:

/*** 获取厂商名* **/public static String getDeviceManufacturer() {return android.os.Build.MANUFACTURER;}/*** 获取产品名* **/public static String getDeviceProduct() {return android.os.Build.PRODUCT;}/*** 获取手机品牌*/public static String getDeviceBrand() {return android.os.Build.BRAND;}/*** 获取手机型号*/public static String getDeviceModel() {return android.os.Build.MODEL;}/*** 获取手机主板名*/public static String getDeviceBoard() {return android.os.Build.BOARD;}/*** 设备名* **/20000public static String getDeviceDevice() {return android.os.Build.DEVICE;}/***** fingerprit 信息* **/public static String getDeviceFubgerprint() {return android.os.Build.FINGERPRINT;}

五、 获取手机硬件名、SDK版本、android版本 、语言支持、默认语言等方法

获取手机硬件名、

SDK版本

、

android版本

 、语言支持、默认语言等方法如下:

/*** 硬件名** **/public static String getDeviceHardware() {return android.os.Build.HARDWARE;}/*** 主机** **/public static String getDeviceHost() {return android.os.Build.HOST;}/**** 显示ID* **/public static String getDeviceDisplay() {return android.os.Build.DISPLAY;}/*** ID** **/public static String getDeviceId() {return android.os.Build.ID;}/*** 获取手机用户名** **/public static String getDeviceUser() {return android.os.Build.USER;}/*** 获取手机 硬件序列号* **/public static String getDeviceSerial() {return android.os.Build.SERIAL;}/*** 获取手机Android 系统SDK** @return*/public static int getDeviceSDK() {return android.os.Build.VERSION.SDK_INT;}/*** 获取手机Android 版本** @return*/public static String getDeviceAndroidVersion() {return android.os.Build.VERSION.RELEASE;}/*** 获取当前手机系统语言。*/public static String getDeviceDefaultLanguage() {return Locale.getDefault().getLanguage();}/*** 获取当前系统上的语言列表(Locale列表)*/public static String getDeviceSupportLanguage() {Log.e("wangjie", "Local:" + Locale.GERMAN);Log.e("wangjie", "Local:" + Locale.ENGLISH);Log.e("wangjie", "Local:" + Locale.US);Log.e("wangjie", "Local:" + Locale.CHINESE);Log.e("wangjie", "Local:" + Locale.TAIWAN);Log.e("wangjie", "Local:" + Locale.FRANCE);Log.e("wangjie", "Local:" + Locale.FRENCH);Log.e("wangjie", "Local:" + Locale.GERMANY);Log.e("wangjie", "Local:" + Locale.ITALIAN);Log.e("wangjie", "Local:" + Locale.JAPAN);Log.e("wangjie", "Local:" + Locale.JAPANESE);return Locale.getAvailableLocales().toString();}

六、 获取 SD 卡存储信息

SD卡信息

1.判断SD是否挂载方法

判断

SD

是否挂载方法如下:

/*** 判断SD是否挂载*/public static boolean isSDCardMount() {return Environment.getExternalStorageState().equals(Environment.MEDIA_MOUNTED);}

2. 获取SD 存储信息的方法

获取

SD

 存储信息的方法如下:

/*** 获取手机存储 ROM 信息** type：用于区分内置存储于外置存储的方法** 内置SD卡 ：INTERNAL_STORAGE = 0;** 外置SD卡：EXTERNAL_STORAGE = 1;* **/public static String getStorageInfo(Context context, int type) {String path = getStoragePath(context, type);/*** 无外置SD 卡判断* **/if (isSDCardMount() == false || TextUtils.isEmpty(path) || path == null) {return "无外置SD卡";}File file = new File(path);StatFs statFs = new StatFs(file.getPath());String stotageInfo;long blockCount = statFs.getBlockCountLong();long bloackSize = statFs.getBlockSizeLong();long totalSpace = bloackSize * blockCount;long availableBlocks = statFs.getAvailableBlocksLong();long availableSpace = availableBlocks * bloackSize;stotageInfo = "可用/总共："+ Formatter.formatFileSize(context, availableSpace) + "/"+ Formatter.formatFileSize(context, totalSpace);return stotageInfo;}

3. 获取手机ROM （内置存储，外置存储）存储路径的方法

获取手机

ROM

 存储信息的方法如下：

/*** 使用反射方法 获取手机存储路径** **/public static String getStoragePath(Context context, int type) {StorageManager sm = (StorageManager) context.getSystemService(Context.STORAGE_SERVICE);try {Method getPathsMethod = sm.getClass().getMethod("getVolumePaths",null);String[] path = (String[]) getPathsMethod.invoke(sm, null);switch (type) {case INTERNAL_STORAGE:return path[type];case EXTERNAL_STORAGE:if (path.length > 1) {return path[type];} else {return null;}default:break;}} catch (Exception e) {e.printStackTrace();}return null;}/*** 获取 手机 RAM 信息 方法 一* */public static String getTotalRAM(Context context) {long size = 0;ActivityManager activityManager = (ActivityManager) context.getSystemService(context.ACTIVITY_SERVICE);MemoryInfo outInfo = new MemoryInfo();activityManager.getMemoryInfo(outInfo);size = outInfo.totalMem;return Formatter.formatFileSize(context, size);}/*** 手机 RAM 信息 方法 二* */public static String getTotalRAMOther(Context context) {String path = "/proc/meminfo";String firstLine = null;int totalRam = 0;try {FileReader fileReader = new FileReader(path);BufferedReader br = new BufferedReader(fileReader, 8192);firstLine = br.readLine().split("\\\\s+")[1];br.close();} catch (Exception e) {e.printStackTrace();}if (firstLine != null) {totalRam = (int) Math.ceil((new Float(Float.valueOf(firstLine)/ (1024 * 1024)).doubleValue()));long totalBytes = 0;}return Formatter.formatFileSize(context, totalRam);}/*** 获取 手机 可用 RAM* */public static String getAvailableRAM(Context context) {long size = 0;ActivityManager activityManager = (ActivityManager) context.getSystemService(context.ACTIVITY_SERVICE);MemoryInfo outInfo = new MemoryInfo();activityManager.getMemoryInfo(outInfo);size = outInfo.availMem;return Formatter.formatFileSize(context, size);}

七、获取手机 RAM、ROM存储信息

1.RAM:

运行时内存，此大小直接决定手机运行的流畅度，相当于电脑内存。

2.ROM :

手机存储（分内置

SD卡

，外置

SD卡

），此大小直接决定着手机可以存储资源的大小，相当于电脑硬盘。

以红米手机为例：

RAM= 1904716KB= 1.82G

红米4 手机 RAM、ROM存储信息

红米4 memory 信息 meminfo

3.获取 

RAM

存储信息的方法如下：

/*** 获取 手机 RAM 信息* */public static String getRAMInfo(Context context) {long totalSize = 0;long availableSize = 0;ActivityManager activityManager = (ActivityManager) context.getSystemService(context.ACTIVITY_SERVICE);MemoryInfo memoryInfo = new MemoryInfo();activityManager.getMemoryInfo(memoryInfo);totalSize = memoryInfo.totalMem;availableSize = memoryInfo.availMem;return "可用/总共：" + Formatter.formatFileSize(context, availableSize)+ "/" + Formatter.formatFileSize(context, totalSize);}

4. 获取手机

ROM

存储信息的方法如下：

/*** 获取手机存储 ROM 信息** type：用于区分内置存储于外置存储的方法** 内置SD卡 ：INTERNAL_STORAGE = 0;** 外置SD卡：EXTERNAL_STORAGE = 1;* **/public static String getStorageInfo(Context context, int type) {String path = getStoragePath(context, type);/*** 无外置SD 卡判断* **/if (isSDCardMount() == false || TextUtils.isEmpty(path) || path == null) {return "无外置SD卡";}File file = new File(path);StatFs statFs = new StatFs(file.getPath());String stotageInfo;long blockCount = statFs.getBlockCountLong();long bloackSize = statFs.getBlockSizeLong();long totalSpace = bloackSize * blockCount;long availableBlocks = statFs.getAvailableBlocksLong();long availableSpace = availableBlocks * bloackSize;stotageInfo = "可用/总共："+ Formatter.formatFileSize(context, availableSpace) + "/"+ Formatter.formatFileSize(context, totalSpace);return stotageInfo;}
