通过调用WifiManager类：IntentFilterfilter=newIntentFilter();filter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);finalWifiManagerwifiManager=(WifiManager)getApplicationContext().getSystemService(Context.WIFI_SERVICE);;registerReceiver(newBroadcastReceiver(){@SuppressLint("UseValueOf")@OverridepublicvoidonReceive(Contextcontext,Intentintent){sb=newStringBuilder();scanList=wifiManager.getScanResults();sb.append("\nNumberOfWificonnections:"+""+scanList.size()+"\n\n");for(inti=0;i<scanList.size();i++){sb.append(newInteger(i+1).toString()+".");sb.append((scanList.get(i)).toString());sb.append("\n\n");}}
