我創(chuàng)建了一個(gè)需要處理 WiFi 的應(yīng)用程序。我有這段代碼this.wifiManager = (WifiManager) this.context.getSystemService(Context.WIFI_SERVICE);String currentSSID = wifiManager.getConnectionInfo().getSSID();問(wèn)題是當(dāng)我已經(jīng)連接到熱點(diǎn)時(shí)當(dāng)前的 SSID 是有效的但是當(dāng)我斷開連接時(shí)它返回最后一個(gè)熱點(diǎn)的 SSID 而不是像 or 之類的null東西equivalent。

經(jīng)過(guò)一些實(shí)驗(yàn)后，我發(fā)現(xiàn)當(dāng)與 hospot 的連接丟失時(shí)，wifiInfo 不會(huì)更新，因此要修復(fù)它，您可以使用
ConnectivityManager manager = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
boolean isConnected = manager.getNetworkInfo(ConnectivityManager.TYPE_WIFI).isConnected();
this.wifiManager = (WifiManager) this.context.getSystemService(Context.WIFI_SERVICE);
String currentSSID = wifiManager.getConnectionInfo().getSSID();
/*
Surround your ssid with " when you compare it with the ssid of the wifimanager
because it will return your SSID surouded by quotes
*/
if(currentSSID.equals("\"" + your_net_ssid + "\"") && isConnected){
//You are realy connected to the hospot
}else{
//The connection dont exist
}
希望這會(huì)很有用！
