回到正题：
对于
int wcgID = mWifiManager.addNetwork(wcg);
wcgid=-1的出现，本人亲测，是因为WifiConfiguration内参数不正确所导致的，如果出现这个问题，可以尝试替换成：public WifiConfiguration createWifiInfo(String SSID, String password, WifiCipherType type) { Log.v(TAG, "SSID = " + SSID + "## Password = " + password + "## Type = " + type); WifiConfiguration config = new WifiConfiguration(); config.allowedAuthAlgorithms.clear(); config.allowedGroupCiphers.clear(); config.allowedKeyManagement.clear(); config.allowedPairwiseCiphers.clear(); config.allowedProtocols.clear(); config.SSID = "\"" + SSID + "\""; WifiConfiguration tempConfig = this.isExsits(SSID); if (tempConfig != null) { mWifiManager.removeNetwork(tempConfig.networkId); } // 分为三种情况：1没有密码2用wep加密3用wpa加密 if (type == WifiCipherType.WIFICIPHER_NOPASS) {// WIFICIPHER_NOPASS config.wepKeys[0] = ""; config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); config.wepTxKeyIndex = 0; } else if (type == WifiCipherType.WIFICIPHER_WEP) { // WIFICIPHER_WEP config.hiddenSSID = true; config.wepKeys[0] = "\"" + password + "\""; config.allowedAuthAlgorithms .set(WifiConfiguration.AuthAlgorithm.SHARED); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40); config.allowedGroupCiphers .set(WifiConfiguration.GroupCipher.WEP104); config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); config.wepTxKeyIndex = 0; } else if (type == WifiCipherType.WIFICIPHER_WPA) { // WIFICIPHER_WPA config.preSharedKey = "\"" + password + "\""; config.hiddenSSID = true; config.allowedAuthAlgorithms .set(WifiConfiguration.AuthAlgorithm.OPEN); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK); config.allowedPairwiseCiphers .set(WifiConfiguration.PairwiseCipher.TKIP); // config.allowedProtocols.set(WifiConfiguration.Protocol.WPA); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); config.allowedPairwiseCiphers .set(WifiConfiguration.PairwiseCipher.CCMP); config.status = WifiConfiguration.Status.ENABLED; } return config; }
