Android通过代码自动连接WiFi

// wc.SSID = "\"" + scanRet.SSID + "\"";
void connect() {
WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
WifiConfiguration wc = new WifiConfiguration();
String SSID = "qvtest";
String key = "12345678";

wc.SSID = "\"" + SSID + "\""; // wifi名称
wc.preSharedKey = "\"" + key + "\""; // wifi密码
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);
int res = wifi.addNetwork(wc);
boolean b = wifi.enableNetwork(res, false);

Toast.makeText(WiFiActivity.this, "res = " + res + "\n" + b + "",
Toast.LENGTH_LONG).show();
}
