I know there is a lot of location depending on your ROM or device
我知道有很多位置取决于您的 ROM 或设备
like /data/wifi/bcm_supp.confor /data/misc/wifi/wpa_supplicant.conf

You need to create a WifiConfigurationinstance like this:
您需要创建一个WifiConfiguration这样的实例：
String networkSSID = "test";
String networkPass = "pass";
WifiConfiguration conf = new WifiConfiguration();
conf.SSID = "\"" + networkSSID + "\""; //
Then, for WEP network you need to do this:
然后，对于 WEP 网络，您需要这样做：
conf.wepKeys[0] = "\"" + networkPass + "\"";
conf.wepTxKeyIndex = 0;
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
For WPA network you need to add passphrase like this:
对于 WPA 网络，您需要像这样添加密码：
conf.preSharedKey = "\""+ networkPass +"\"";
For Open network you need to do this:
对于开放网络，您需要执行以下操作：
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
Then, you need to add it to Android Wi-Fi manager settings:
然后，您需要将其添加到 Android Wi-Fi 管理器设置中：
WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
wifiManager.add(conf);
And finally, you might need to enable it, so Android connects to it:
最后，您可能需要启用它，以便 Android 连接到它：
List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
for (WifiConfiguration i : list) {
if (i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
wm.disconnect();
wm.enableNetwork(i.networkId, true);
wm.reconnect();
break;
}
}
In case of WEP, if your password is in hex, you do not need to surround it with quotation marks.
在 WEP 的情况下，如果您的密码是十六进制的，则不需要用引号将其括起来。
