完整的解决方案：

try {

WifiManager wifi = (WifiManager)

context.getSystemService(Context.WIFI_SERVICE);

WifiConfiguration wc = new WifiConfiguration();

wc.SSID = "\"SSIDName\"";

wc.preSharedKey = "\"password\"";

wc.hiddenSSID = true;

wc.status = WifiConfiguration.Status.ENABLED;

wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);

wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);

wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);

wc.allowedPairwiseCiphers

.set(WifiConfiguration.PairwiseCipher.TKIP);

wc.allowedPairwiseCiphers

.set(WifiConfiguration.PairwiseCipher.CCMP);

wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);

boolean b=wifi.isWifiEnabled();

if (b) {

wifi.setWifiEnabled(false);

Toast.makeText(context, "yes", Toast.LENGTH_SHORT).show();

} else {

wifi.setWifiEnabled(true);

Toast.makeText(context, "no", Toast.LENGTH_SHORT).show();

}

//Log.d("WifiPreference", "enableNetwork returned " + b );

} catch (Exception e) {

e.printStackTrace();

}
