Android判斷是Wifi還是4G網路代碼_Android

本文執行個體為大家分享了Android判斷是Wifi還是4G網路的具體代碼，供大家參考，具體內容如下

package com.chengxinet.bobo.utils;import android.content.Context;import android.net.ConnectivityManager;import android.net.NetworkInfo;import android.telephony.TelephonyManager;/** * Created by Administrator on 2016/1/7. */public class NetworkUtils {  public static boolean isNetworkAvailable(Context c) {    Context context = c.getApplicationContext();    // 擷取手機所有串連管理對象（包括對wi-fi,net等串連的管理）    ConnectivityManager connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);    if (connectivityManager == null) {      return false;    } else {      // 擷取NetworkInfo對象      NetworkInfo[] networkInfo = connectivityManager.getAllNetworkInfo();      if (networkInfo != null && networkInfo.length > 0) {        for (NetworkInfo aNetworkInfo : networkInfo) {//          System.out.println(i + "===狀態===" + networkInfo[i].getState());//          System.out.println(i + "===類型===" + networkInfo[i].getTypeName());          // 判斷當前網路狀態是否為串連狀態          if (aNetworkInfo.getState() == NetworkInfo.State.CONNECTED) {            return true;          }        }      }    }    return false;  }  /**   * 判斷WIFI是否開啟   * @param context   * @return   */  public static boolean isWifiEnabled(Context context) {    ConnectivityManager mgrConn = (ConnectivityManager) context        .getSystemService(Context.CONNECTIVITY_SERVICE);    TelephonyManager mgrTel = (TelephonyManager) context        .getSystemService(Context.TELEPHONY_SERVICE);    return ((mgrConn.getActiveNetworkInfo() != null && mgrConn        .getActiveNetworkInfo().getState() == NetworkInfo.State.CONNECTED) || mgrTel        .getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS);  }  /**   * 判斷是否是3G網路   * @param context   * @return   */  public static boolean is3rd(Context context) {    ConnectivityManager cm = (ConnectivityManager) context        .getSystemService(Context.CONNECTIVITY_SERVICE);    NetworkInfo networkINfo = cm.getActiveNetworkInfo();    if (networkINfo != null        && networkINfo.getType() == ConnectivityManager.TYPE_MOBILE) {      return true;    }    return false;  }  /**   * 判斷是wifi還是3g網路   * @param context   * @return   */  public static boolean isWifi(Context context) {    ConnectivityManager cm = (ConnectivityManager) context        .getSystemService(Context.CONNECTIVITY_SERVICE);    NetworkInfo networkINfo = cm.getActiveNetworkInfo();    if (networkINfo != null        && networkINfo.getType() == ConnectivityManager.TYPE_WIFI) {      return true;    }    return false;  }}
