【移动应用开发技术】Android中怎么获取设备状态信息

这期内容当中在下将会给大家带来有关Android中怎么获取设备状态信息，文章内容丰富且以专业的角度为大家分析和叙述，阅读完这篇文章希望大家可以有所收获。1通过build获取手机硬件信息运用反射获取Build信息，然后从build中得到对应字段的值。这种情况适用于获取所有的build信息。或者直接调用Build类直接拿里面的字段名，如：android.os.Build.MODEL;//手机型号。这是为了获取单独某个手机信息的方法，直接调用Build的字段即可拿到对应信息，简单快捷。别忘了加权限<uses-permission

android:name="android.permission.READ_PHONE_STATE"/>下面是Build类的字段所对应的信息String

builder2.通过getSystemService()来获取Ip地址Context.getSystemService()这个方法是非常实用的方法，只须在参数里输入一个String字符串常量就可得到对应的服务管理方法，可以用来获取绝大部分的系统信息，各个常量对应的含义如下。WINDOW_SERVICE(“window”)Thetop-levelwindowmanagerinwhichyoucanplacecustomwindows.ThereturnedobjectisaWindowManager.LAYOUT_INFLATER_SERVICE(“layout_inflater”)ALayoutInflaterforinflatinglayoutresourcesinthiscontext.ACTIVITY_SERVICE(“activity”)AActivityManagerforinteractingwiththeglobalactivitystateofthesystem.POWER_SERVICE(“power”)APowerManagerforcontrollingpowermanagement.ALARM_SERVICE(“alarm”)AAlarmManagerforreceivingintentsatthetimeofyourchoosing.NOTIFICATION_SERVICE(“notification”)ANotificationManagerforinformingtheuserofbackgroundevents.KEYGUARD_SERVICE(“keyguard”)AKeyguardManagerforcontrollingkeyguard.LOCATION_SERVICE(“location”)ALocationManagerforcontrollinglocation(e.g.,GPS)updates.SEARCH_SERVICE(“search”)ASearchManagerforhandlingsearch.VIBRATOR_SERVICE(“vibrator”)AVibratorforinteractingwiththevibratorhardware.CONNECTIVITY_SERVICE(“connection”)AConnectivityManagerforhandlingmanagementofnetworkconnections.WIFI_SERVICE(“wifi”)AWifiManagerformanagementofWi-Ficonnectivity.WIFI_P2P_SERVICE(“wifip2p”)AWifiP2pManagerformanagementofWi-FiDirectconnectivity.INPUT_METHOD_SERVICE(“input_method”)AnInputMethodManagerformanagementofinputmethods.UI_MODE_SERVICE(“uimode”)AnUiModeManagerforcontrollingUImodes.DOWNLOAD_SERVICE(“download”)ADownloadManagerforrequestingHTTPdownloadsBATTERY_SERVICE(“batterymanager”)ABatteryManagerformanagingbatterystateJOB_SCHEDULER_SERVICE(“taskmanager”)AJobSchedulerformanagingscheduledtasksNETWORK_STATS_SERVICE(“netstats”)ANetworkStatsManagerforqueryingnetworkusagestatistics.Note:SystemservicesobtainedviathisAPImaybecloselyassociatedwiththeContextinwhichtheyareobtainedfrom.Ingeneral,donotsharetheserviceobjectsbetweenvariousdifferentcontexts(Activities,Applications,Services,Providers,etc.)ParametersnameThenameofthedesiredservice.ReturnsTheserviceornullifthenamedoesnotexist.要获取IP地址需要用到Context.CONNECTIVITY_SERVICE，这个常量所对应的网络连接的管理方法。代码如下需要权限：<uses-permission

android:name="android.permission.ACCESS_NETWORK_STATE"

/>/**获得IP地址，分为两种情况，一是wifi下，二是移动网络下，得到的ip地址是不一样的*/

public

static

String

getIPAddress()

{

Context

context=MyApp.getContext();

NetworkInfo

info

=

((ConnectivityManager)

context

.getSystemService(Context.CONNECTIVITY_SERVICE)).getActiveNetworkInfo();

if

(info

!=

null

&&

info.isConnected())

{

if

(info.getType()

==

ConnectivityManager.TYPE_MOBILE)

{//当前使用2G/3G/4G网络

try

{

//Enumeration<NetworkInterface>

en=NetworkInterface.getNetworkInterfaces();

for

(Enumeration<NetworkInterface>

en

=

NetworkInterface.getNetworkInterfaces();

en.hasMoreElements();

)

{

NetworkInterface

intf

=

en.nextElement();

for

(Enumeration<InetAddress>

enumIpAddr

=

intf.getInetAddresses();

enumIpAddr.hasMoreElements();

)

{

InetAddress

inetAddress

=

enumIpAddr.nextElement();

if

(!inetAddress.isLoopbackAddress()

&&

inetAddress

instanceof

Inet4Address)

{

return

inetAddress.getHostAddress();

}

}

}

}

catch

(SocketException

e)

{

e.printStackTrace();

}

}

else

if

(info.getType()

==

ConnectivityManager.TYPE_WIFI)

{//当前使用无线网络

WifiManager

wifiManager

=

(WifiManager)

context.getSystemService(Context.WIFI_SERVICE);

WifiInfo

wifiInfo

=

wifiManager.getConnectionInfo();

//调用方法将int转换为地址字符串

String

ipAddress

=

intIP2StringIP(wifiInfo.getIpAddress());//得到IPV4地址

return

ipAddress;

}

}

else

{

//当前无网络连接,请在设置中打开网络

}

return

null;

}

/**

*

将得到的int类型的IP转换为String类型

*

@param

ip

*

@return

*/

public

static

String

intIP2StringIP(int

ip)

{

return

(ip

&

0xFF)

+

"."

+

((ip

>>

8)

&

0xFF)

+

"."

+

((ip

>>

16)

&

0xFF)

"."

(ip

&

0xFF);

}3.获得Mac地址我们知道mac地址是网卡的唯一标识，通过这个可以判断网络当前连接的手机设备有几台。代码如下：

public

static

String

getMacAddress(){

/*获取mac地址有一点需要注意的就是android

6.0版本后，以下注释方法不再适用，不管任何手机都会返回"02:00:00:00:00:00"这个默认的mac地址，这是googel官方为了加强权限管理而禁用了getSYstemService(Context.WIFI_SERVICE)方法来获得mac地址。*/

//

String

macAddress=

"";

//

WifiManager

wifiManager

=

(WifiManager)

MyApp.getContext().getSystemService(Context.WIFI_SERVICE);

//

WifiInfo

wifiInfo

=

wifiManager.getConnectionInfo();

//

macAddress

=

wifiInfo.getMacAddress();

//

return

macAddress;

String

macAddress

=

null;

StringBuffer

buf

=

new

StringBuffer();

NetworkInterface

networkInterface

=

null;

try

{

networkInterface

=

NetworkInterface.getByName("eth2");

if

(networkInterface

==

null)

{

networkInterface

=

NetworkIn
