检测网络状态 1.1 实现思路 获得ConnectivityManager对象 ConnectivityManager主要用于查看网络状态和管理网络连接相关的操作 获取ConnectivityManager...对象 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE...对象 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE...对象 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE...对象 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE
ConnectivityManager cm = (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); // 获取代表联网状态的...NetWorkInfo对象 NetworkInfo wifiInfo = cm.getNetworkInfo(ConnectivityManager.TYPE_WIFI); return wifiInfo...= null && wifiInfo.isConnected() 返回true则是wifi环境，并且可以正常使用，否则wifi 不能用 ConnectivityManager主要管理和网络连接相关的操作...connectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE);...()==ConnectivityManager.TYPE_WIFI){ //判断WIFI网 }else if( networkInfo.getType()==ConnectivityManager.TYPE_MOBILE
获取 WIFI 状态 : WIFI 状态可以使用 ConnectivityManager 获取 , 调用 getActiveNetworkInfo 方法获取 NetworkInfo 后 , 先判定当前网络是否连接...) 方法 , 跨进程获取 ConnectivityManager 服务 ; // 获取连接管理器 ConnectivityManager connectivityManager..., 就说明当前是 WIFI 网络 ; networkInfo.getType() == ConnectivityManager.TYPE_WIFI 2 ....connectivityManager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE...); // 获取网络信息 NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
对象 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE...); //获取ConnectivityManager对象对应的NetworkInfo对象 //获取WIFI连接的信息 NetworkInfo wifiNetworkInfo...= connMgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI); //获取移动数据连接的信息 NetworkInfo dataNetworkInfo...= connMgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE); if (wifiNetworkInfo.isConnected() &...对象 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE
= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context...一般可以通过ConnectivityManager来完成该工作。

package com.who; import android.app.Activity; import android.content.Context; import android.net.ConnectivityManager...activity) { Context context = activity.getApplicationContext(); // 获取手机所有连接管理对象（包括对wi-fi,net等连接的管理） ConnectivityManager...connectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE...); if (connectivityManager == null) { return false; } else { // 获取NetworkInfo对象 NetworkInfo...[] networkInfo = connectivityManager.getAllNetworkInfo(); if (networkInfo !
= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService(...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService(...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService(...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService(...connMgr = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo

在android中判断网络需要用到ConnectivityManager，下面的方法演示了如何用ConnectivityManager判断当前是否联网： public static boolean...isNetworkConnected() { ConnectivityManager cm = (ConnectivityManager) AppContext.getInstance..., ConnectivityManager.TYPE_WIFI, ConnectivityManager.TYPE_WIMAX, ConnectivityManager.TYPE_ETHERNET..., ConnectivityManager.TYPE_BLUETOOTH 五种，其中只有ConnectivityManager.TYPE_MOBILE, ConnectivityManager.TYPE_WIFI...是跟互联网有关的，可见ConnectivityManager并不是专门管理互联网连接的，还负责蓝牙等连接。
(); ConnectivityManager connectivityManager = (ConnectivityManager)context.getSystemService(Context.CONNECTIVITY_SERVICE...); 2、获取NetworkInfo对象 // 获取NetworkInfo对象 NetworkInfo[] networkInfo = connectivityManager.getAllNetworkInfo...= null) { // 获取手机所有连接管理对象(包括对wi-fi,net等连接的管理) ConnectivityManager manager = (ConnectivityManager...= null) { //获取手机所有连接管理对象(包括对wi-fi,net等连接的管理) ConnectivityManager manager = (ConnectivityManager...= null) { //获取手机所有连接管理对象 ConnectivityManager manager = (ConnectivityManager)
(intent.getAction())) { ConnectivityManager manager = (ConnectivityManager) context .getSystemService...ConnectivityManager和NetworkInfo ConnectivityManager主要用来干什么 Monitor network connections (Wi-Fi, GPRS,...ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context .CONNECTIVITY_SERVICE...connectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE);...connectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE);
mgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo...conManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE...conMan = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE...); State mobile = conMan.getNetworkInfo(ConnectivityManager.TYPE_MOBILE) .getState...(); State wifi = conMan.getNetworkInfo(ConnectivityManager.TYPE_WIFI) .getState
final int NETWORK_TYPE_UNKNOWN = 0; public static int getNetworkType(Context context) { ConnectivityManager...connectMgr = (ConnectivityManager) context.getSystemService( Context.CONNECTIVITY_SERVICE...= null) { if (info.getType() == ConnectivityManager.TYPE_MOBILE) { switch...)) { ConnectivityManager connectivityManager = (ConnectivityManager) getSystemService(...Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo
= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context.getSystemService...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context.getSystemService...NetworkInfo mMobileNetworkInfo = mConnectivityManager .getNetworkInfo(ConnectivityManager.TYPE_MOBILE...= null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService...= null) { return mNetworkInfo.getType() == ConnectivityManager.TYPE_WIFI;
回调接口（NetEvevt） BaseActivity实现这个接口 直接上代码 NetUtil import android.content.Context; import android.net.ConnectivityManager...connectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE...); NetworkInfo activeNetworkInfo = connectivityManager .getActiveNetworkInfo(); if (activeNetworkInfo...= null && activeNetworkInfo.isConnected()) { if (activeNetworkInfo.getType() == (ConnectivityManager.TYPE_WIFI...)) { return NETWORK_WIFI; } else if (activeNetworkInfo.getType() == (ConnectivityManager.TYPE_MOBILE
However, the ConnectivityManager API provides a more robust method to request a callback only when specified...public class MainActivity extends Activity { private ConnectivityManager.NetworkCallback networkCallback...; private ConnectivityManager connectivityManager; @Override protected void onCreate(Bundle savedInstanceState...= (ConnectivityManager) getSystemService(Context.CONNECTIVITY_SERVICE); connectivityManager.registerNetworkCallback...(networkCallback); } private class NetworkCallbackImpl extends ConnectivityManager.NetworkCallback
