获取已连接的WiFi名称

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>

//获取SSID
//完美解决9.0的机型，必须请求GPS权限并打开GPS才可以正确获取到WIFI名称
private String getNetConfListForSSID() {String ssid = "";WifiManager mWifiManager = (WifiManager) getApplicationContext().getSystemService(Context.WIFI_SERVICE);if (mWifiManager != null) {WifiInfo info = mWifiManager.getConnectionInfo();//android10.0需要申请新添加的隐私权限ACCESS_FINE_LOCATION，如果还需要后台获取或者使用wifi api则还需要申请后台使用定位权限ACCESS_BACKGROUND_LOCATION//链接：https://www.jianshu.com/p/7c05a99f94daif(!IsNullString(info.getSSID())){ssid = info.getSSID();Log.e("lgq","---直接获取ssid:"+ssid);}else{int networkId = info.getNetworkId();@SuppressLint("MissingPermission")List<WifiConfiguration> netConfList = mWifiManager.getConfiguredNetworks();if(netConfList==null){return "";}for (WifiConfiguration wificonf:netConfList){if(wificonf.networkId == networkId){Log.e("lgq","---间接获取ssid："+ssid);}}}}if (ssid!=null && ssid.startsWith("\"")) {ssid = ssid.substring(1);}if (ssid!=null && ssid.endsWith("\"")) {ssid = ssid.substring(0, ssid.length() - 1);}return ssid;
}//判断字符是否为空或者没数据
public static boolean IsNullString(String str) {if (str != null && !TextUtils.isEmpty(str) && !TextUtils.equals("", str.trim())) {return false;} else {return true;}
}

获取wifi的mac地址

public class D2WifiAdminSimple {private final Context mContext;public D2WifiAdminSimple(Context context) {mContext = context;}//获取SSID//完美解决9.0的机型，必须请求GPS权限并打开GPS才可以正确获取到WIFI名称public String getWifiConnectedSsid() {String  ssid="";WifiManager mWifiManager=(WifiManager)mContext.getApplicationContext().getSystemService(Context.WIFI_SERVICE);if(mWifiManager!=null){WifiInfo info=mWifiManager.getConnectionInfo();int networkId=info.getNetworkId();List<WifiConfiguration> netConfList=mWifiManager.getConfiguredNetworks();for (WifiConfiguration wificonf:netConfList){if(wificonf.networkId == networkId){ssid=wificonf.SSID;}}}if (ssid!=null && ssid.startsWith("\"")) {ssid = ssid.substring(1);}if (ssid!=null && ssid.endsWith("\"")) {ssid = ssid.substring(0, ssid.length() - 1);}return ssid;}public String getWifiConnectedBssid() {WifiInfo mWifiInfo = getConnectionInfo();String bssid = null;if (mWifiInfo != null && isWifiConnected()) {bssid = mWifiInfo.getBSSID();}return bssid;}// get the wifi info which is "connected" in wifi-settingprivate WifiInfo getConnectionInfo() {WifiManager mWifiManager = (WifiManager) mContext.getApplicationContext().getSystemService(Context.WIFI_SERVICE);WifiInfo wifiInfo = mWifiManager.getConnectionInfo();return wifiInfo;}private boolean isWifiConnected() {NetworkInfo mWiFiNetworkInfo = getWifiNetworkInfo();boolean isWifiConnected = false;if (mWiFiNetworkInfo != null) {isWifiConnected = mWiFiNetworkInfo.isConnected();}return isWifiConnected;}private NetworkInfo getWifiNetworkInfo() {ConnectivityManager mConnectivityManager = (ConnectivityManager) mContext.getApplicationContext().getSystemService(Context.CONNECTIVITY_SERVICE);NetworkInfo mWiFiNetworkInfo = mConnectivityManager.getNetworkInfo(ConnectivityManager.TYPE_WIFI);return mWiFiNetworkInfo;}
}

private D2WifiAdminSimple mWifiAdmin;

String strWifiBSSID = mWifiAdmin.getWifiConnectedBssid();

1、添加权限

<uses-permission android:name="android.permission.INTERNET"/>
<!-- 网络状态 -->
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />

2、创建监听广播NetWorkChangReceiver

public class NetWorkChangReceiver extends BroadcastReceiver {/*** 获取连接类型** @param type* @return*/private String getConnectionType(int type) {String connType = "";if (type == ConnectivityManager.TYPE_MOBILE) {connType = "3G网络数据";} else if (type == ConnectivityManager.TYPE_WIFI) {connType = "WIFI网络";}return connType;}@Overridepublic void onReceive(Context context, Intent intent) {if (WifiManager.WIFI_STATE_CHANGED_ACTION.equals(intent.getAction())) {// 监听wifi的打开与关闭，与wifi的连接无关int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, 0);Log.e("lgqTAG", "wifiState:" + wifiState);switch (wifiState) {case WifiManager.WIFI_STATE_DISABLED:break;case WifiManager.WIFI_STATE_DISABLING:break;}}// 监听网络连接，包括wifi和移动数据的打开和关闭,以及连接上可用的连接都会接到监听if (ConnectivityManager.CONNECTIVITY_ACTION.equals(intent.getAction())) {//获取联网状态的NetworkInfo对象NetworkInfo info = intent.getParcelableExtra(ConnectivityManager.EXTRA_NETWORK_INFO);if (info != null) {//如果当前的网络连接成功并且网络连接可用if (NetworkInfo.State.CONNECTED == info.getState() && info.isAvailable()) {if (info.getType() == ConnectivityManager.TYPE_WIFI || info.getType() == ConnectivityManager.TYPE_MOBILE) {Log.i("lgqTAG", getConnectionType(info.getType()) + "连上");}} else {Log.i("lgqTAG", getConnectionType(info.getType()) + "断开");}}}}
}

3、配置广播

<!--监听网络状态-->
<receiver android:name=".NetWorkChangReceiver" ><intent-filter><action android:name="android.net.conn.CONNECTIVITY_CHANGE" /><action android:name="android.net.wifi.WIFI_STATE_CHANGED" /><action android:name="android.net.wifi.STATE_CHANGE" /></intent-filter>
</receiver>

4、注册广播

private NetWorkChangReceiver netWorkChangReceiver;

netWorkChangReceiver = new NetWorkChangReceiver();
IntentFilter filter = new IntentFilter();
filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
filter.addAction(ConnectivityManager.CONNECTIVITY_ACTION);
registerReceiver(netWorkChangReceiver, filter);

5、退出时

unregisterReceiver(netWorkChangReceiver);

2、判断网络连接方式——wifi。2G，3G。4G。5G

public class Constants {/*** Unknown network class*/public static final int NETWORK_CLASS_UNKNOWN = 0;/*** wifi net work*/public static final int NETWORK_WIFI = 1;/*** "2G" networks*/public static final int NETWORK_CLASS_2_G = 2;/*** "3G" networks*/public static final int NETWORK_CLASS_3_G = 3;/*** "4G" networks*/public static final int NETWORK_CLASS_4_G = 4;}

public static int getNetWorkClass(Context context) {TelephonyManager telephonyManager = (TelephonyManager) context.getSystemService(Context.TELEPHONY_SERVICE);switch (telephonyManager.getNetworkType()) {case TelephonyManager.NETWORK_TYPE_GPRS:case TelephonyManager.NETWORK_TYPE_EDGE:case TelephonyManager.NETWORK_TYPE_CDMA:case TelephonyManager.NETWORK_TYPE_1xRTT:case TelephonyManager.NETWORK_TYPE_IDEN:return Constants.NETWORK_CLASS_2_G;case TelephonyManager.NETWORK_TYPE_UMTS:case TelephonyManager.NETWORK_TYPE_EVDO_0:case TelephonyManager.NETWORK_TYPE_EVDO_A:case TelephonyManager.NETWORK_TYPE_HSDPA:case TelephonyManager.NETWORK_TYPE_HSUPA:case TelephonyManager.NETWORK_TYPE_HSPA:case TelephonyManager.NETWORK_TYPE_EVDO_B:case TelephonyManager.NETWORK_TYPE_EHRPD:case TelephonyManager.NETWORK_TYPE_HSPAP:return Constants.NETWORK_CLASS_3_G;case TelephonyManager.NETWORK_TYPE_LTE:return Constants.NETWORK_CLASS_4_G;default:return Constants.NETWORK_CLASS_UNKNOWN;}
}

public static int getNetWorkStatus(Context context) {//等于1时是wifi网络，等于4是4G网络，等于3是3G网络int netWorkType = Constants.NETWORK_CLASS_UNKNOWN;ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();if (networkInfo != null && networkInfo.isConnected()) {int type = networkInfo.getType();if (type == ConnectivityManager.TYPE_WIFI) {netWorkType = Constants.NETWORK_WIFI;} else if (type == ConnectivityManager.TYPE_MOBILE) {netWorkType = getNetWorkClass(context);}}return netWorkType;
}

3、判断网络是否连接

/*** 判断是否有网络连接* @param context* @return*/
public static boolean isNetworkConnected(Context context) {//true是链接，false是没链接if (context != null) {ConnectivityManager mConnectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();if (mNetworkInfo != null) {return mNetworkInfo.isAvailable();}}return false;
}
