言簡意賅的說吧。設定androidwifi連線，

1.new 一個wificonfiguration物件。

2.設定這個物件的一些屬性。

1. WifiConfiguration wc = new WifiConfiguration();  
2. wc.SSID = "\""+sr.SSID+"\"";      //<span style="color: rgb(255, 0, 0); ">這個地方一定要注意了。旁邊的“是不能夠省略的。密碼的地方也一樣。</span>
3. wc.preSharedKey = "\""+etPassword.getText().toString()+
   "\"";      //該熱點的密碼
4. wc.hiddenSSID = true;  
5. wc.status = WifiConfiguration.Status.ENABLED;  
6. wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);  
7. wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);  
8. wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);  
9. wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);  
10. wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);  
11. wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);  
12. wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);  

3.判斷wifi是否加密：

1. publicstaticint getSecurity(ScanResult result) {  
2.     if (result.capabilities.contains(
   "WEP")) {  
3.         return1;  
4.     } elseif (result.capabilities.contains("PSK")) {  
5.         return2;  
6.     } elseif (result.capabilities.contains("EAP")) {  
7.         return3;  
8.     }  
9.     return0;  
10. }  

4.連線未加密wifi連線：

1. <pre name="code"class="java">WifiConfiguration config = new WifiConfiguration();  
2. config.SSID = "\"" + sr.SSID + "\"";  
3. config.allowedKeyManagement.set(KeyMgmt.NONE);  
4. int networkId = wifiManager.addNetwork(config);  
5. if(networkId != -1){  
6.     wifiManager.enableNetwork(networkId, false);  
7.     wifiManager.saveConfiguration();  
8. }
