在程序中連接WIFI熱點(diǎn),如果此WIFI熱點(diǎn)已配置過,那就非常簡單.教科書上都有.但如果是一個(gè)新的WIFI網(wǎng)絡(luò),那問題就來了.按習(xí)慣,先在網(wǎng)上搜了一遍,如果有現(xiàn)成的.那事情就算搞定了.誰知,竟然找不到完整的代碼.難道沒人連接成功過?

看來只能是自力更生了.看一下類庫的說明http://developer.android.com/reference/android/net/wifi/WifiConfiguration.html#allowedAuthAlgorithms

1.連接WEP加密方式的WIFI

 調(diào)試花了不少時(shí)間,但還是成功了.附上源碼.

 1 WifiManager wifi = (WifiManager) getSystemService(wifi.this.WIFI_SERVICE);
 2 
 3       WifiConfiguration wc = new WifiConfiguration();
 4 
 5       /* ---------------------WEP連接方式---------------------*/
 6       
 7       wc.SSID = "\"SSID\"";
 8       wc.hiddenSSID = false;
 9 
10       wc.status = WifiConfiguration.Status.ENABLED;
11 
12       wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
13       wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
14 
15       wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
16       wc.wepTxKeyIndex = 0;
17 
18       wc.wepKeys[0] = "PSW";
19 
20       int res = wifi.addNetwork(wc);
21 
22       boolean b = wifi.enableNetwork(res, true);
23 
24 /* ---------------------WEP連接方式END---------------------*/
25 
26 
27  

2.連接WPA加密方式的WIFI

 1 WifiConfiguration wc = new WifiConfiguration();
 2                 
 3                 /*----------------------WPA連接方式------------------------*/
 4                 wc.SSID = "\"SSID\"";
 5                 wc.hiddenSSID = false;
 6 
 7                 wc.status = WifiConfiguration.Status.ENABLED;
 8                 
 9 
10                 wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
11                 wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
12                 wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
13                 wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
14                 
15                 wc.preSharedKey = "\"PSW\"";
16 
17                 int res = wifi.addNetwork(wc);
18 
19                 boolean b = wifi.enableNetwork(res, true);
20                 /*----------------------WPA連接方式END------------------------*/

還有附上我的WIFI配置截圖.無線路由是TP-LINK,比較常見的一款路由器.
