android 网络监测 _android

不操千曲而后晓声，观千剑而后识器。这篇文章主要讲述android 网络监测相关的知识，希望能为你提供帮助。

public class NetWorkStateReceiver extends BroadcastReceiver { @Override public void onReceive(Context context, Intent intent) {System.out.println("网络状态发生变化"); //检测API是不是小于23，因为到了API23之后getNetworkInfo(int networkType)方法被弃用 if (android.os.Build.VERSION.SDK_INT < android.os.Build.VERSION_CODES.LOLLIPOP) {//获得ConnectivityManager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() & & dataNetworkInfo.isConnected()) { Toast.makeText(context, "WIFI已连接,移动数据已连接", Toast.LENGTH_SHORT).show(); } else if (wifiNetworkInfo.isConnected() & & !dataNetworkInfo.isConnected()) { Toast.makeText(context, "WIFI已连接,移动数据已断开", Toast.LENGTH_SHORT).show(); } else if (!wifiNetworkInfo.isConnected() & & dataNetworkInfo.isConnected()) { Toast.makeText(context, "WIFI已断开,移动数据已连接", Toast.LENGTH_SHORT).show(); } else { Toast.makeText(context, "WIFI已断开,移动数据已断开", Toast.LENGTH_SHORT).show(); } //API大于23时使用下面的方式进行网络监听 }else {System.out.println("API level 大于23"); //获得ConnectivityManager对象 ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); //获取所有网络连接的信息 Network[] networks = connMgr.getAllNetworks(); //用于存放网络连接信息 StringBuilder sb = new StringBuilder(); //通过循环将网络信息逐个取出来 for (int i=0; i < networks.length; i++){ //获取ConnectivityManager对象对应的NetworkInfo对象 NetworkInfo networkInfo = connMgr.getNetworkInfo(networks[i]); sb.append(networkInfo.getTypeName() + " connect is " + networkInfo.isConnected()); } Toast.makeText(context, sb.toString(),Toast.LENGTH_SHORT).show(); } } }
