如何以编程方式连接到 Android 中的特定 Wi-Fi 网络？

问题描述 投票：0回答：12

我想设计一个应用程序，显示可用的 Wi-Fi 网络列表并连接到用户选择的网络。

我已经实现了显示扫描结果的部分。现在我想连接到用户从扫描结果列表中选择的特定网络。

我该怎么做？

您需要创建 

WifiConfiguration
实例，如下所示：

String networkSSID = "test";
String networkPass = "pass";

WifiConfiguration conf = new WifiConfiguration();
conf.SSID = "\"" + networkSSID + "\"";   // Please note the quotes. String should contain ssid in quotes

然后，对于 WEP 网络，您需要执行以下操作：

conf.wepKeys[0] = "\"" + networkPass + "\""; 
conf.wepTxKeyIndex = 0;
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);

对于 WPA 网络，您需要添加如下密码：

conf.preSharedKey = "\""+ networkPass +"\"";

对于开放网络，您需要执行以下操作：

conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);

然后，您需要将其添加到 Android wifi 管理器设置中：

WifiManager wifiManager = (WifiManager)context.getSystemService(Context.WIFI_SERVICE); 
wifiManager.addNetwork(conf);

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 + "\"")) {
         wifiManager.disconnect();
         wifiManager.enableNetwork(i.networkId, true);
         wifiManager.reconnect();               

         break;
    }           
 }

UPD：对于 WEP，如果您的密码是十六进制，则不需要用引号引起来。

之前的答案有效，但解决方案实际上可以更简单。不需要循环遍历已配置的网络列表，因为当您通过 WifiManager 添加网络时会获取网络 ID。

所以完整的、简化的解决方案看起来像这样：

WifiConfiguration wifiConfig = new WifiConfiguration();
wifiConfig.SSID = String.format("\"%s\"", ssid);
wifiConfig.preSharedKey = String.format("\"%s\"", key);

WifiManager wifiManager = (WifiManager)getSystemService(WIFI_SERVICE);
//remember id
int netId = wifiManager.addNetwork(wifiConfig);
wifiManager.disconnect();
wifiManager.enableNetwork(netId, true);
wifiManager.reconnect();

在连接 WIFI 网络之前，您需要检查 WIFI 网络的安全类型 ScanResult 类是否具有功能。该字段为您提供网络类型

参考：https://developer.android.com/reference/android/net/wifi/ScanResult.html#capability

WIFI 网络有三种。

首先，实例化一个WifiConfiguration对象并填写网络的SSID（注意必须用双引号括起来），将初始状态设置为禁用，并指定网络的优先级（40左右的数字似乎效果很好）。

WifiConfiguration wfc = new WifiConfiguration();

wfc.SSID = "\"".concat(ssid).concat("\"");
wfc.status = WifiConfiguration.Status.DISABLED;
wfc.priority = 40;

现在是更复杂的部分：我们需要填写 WifiConfiguration 的几个成员来指定网络的安全模式。 对于开放网络。

wfc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
wfc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wfc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
wfc.allowedAuthAlgorithms.clear();
wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);

对于使用 WEP 的网络；请注意，WEP 密钥也用双引号引起来。

wfc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
wfc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wfc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
wfc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
wfc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);

if (isHexString(password)) wfc.wepKeys[0] = password;
else wfc.wepKeys[0] = "\"".concat(password).concat("\"");
wfc.wepTxKeyIndex = 0;

对于使用 WPA 和 WPA2 的网络，我们可以为两者设置相同的值。

wfc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
wfc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
wfc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
wfc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
wfc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);

wfc.preSharedKey = "\"".concat(password).concat("\"");

最后，我们可以将网络添加到 WifiManager 的已知列表中

WifiManager wfMgr = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
int networkId = wfMgr.addNetwork(wfc);
if (networkId != -1) {
 // success, can call wfMgr.enableNetwork(networkId, true) to connect
}

感谢@raji-ramamoorthi 和@kenota

对我有用的解决方案是该线程中上述贡献者的组合。

要得到

ScanResult
，这就是过程。

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);
if (wifi.isWifiEnabled() == false) {
            Toast.makeText(getApplicationContext(), "wifi is disabled..making it enabled", Toast.LENGTH_LONG).show();
            wifi.setWifiEnabled(true);
        }

BroadcastReceiver broadcastReceiver = new BroadcastReceiver() {
            @Override
            public void onReceive(Context c, Intent intent) {
                 wifi.getScanResults();
            }
        };

注意

unregister
，在
onPause
和
onStop
住这个
unregisterReceiver(broadcastReceiver);

public void connectWiFi(ScanResult scanResult) {

            Log.v("rht", "Item clicked, SSID " + scanResult.SSID + " Security : " + scanResult.capabilities);

            String networkSSID = scanResult.SSID;

            conf.status = WifiConfiguration.Status.ENABLED;
            conf.priority = 40;

在 API 级别 29 中，

WifiManager.enableNetwork()
方法已弃用。根据 Android API 文档（查看此处）：

  1. 请参阅 WifiNetworkSpecifier.Builder#build() 了解触发 Wi-Fi 网络连接的新机制。
  2. 有关添加 Wi-Fi 的新 API，请参阅 addNetworkSuggestions(java.util.List)、removeNetworkSuggestions(java.util.List) 自动连接到 wifi 时要考虑的网络。兼容性 注意：对于面向 Build.VERSION_CODES.Q 或更高版本的应用程序，此 API 将始终返回 false。

从 API 级别 29 开始，要连接到 WiFi 网络，您将需要使用 

WifiNetworkSpecifier
。您可以在 https://developer.android.com/reference/android/net/wifi/WifiNetworkSpecifier.Builder.html#build()

找到示例代码

如果您的设备知道 Wifi 配置（已存储），我们就可以绕过火箭科学。只需循环遍历配置检查 SSID 是否匹配。如果是这样，请连接并返回。

设置权限：

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" />
<uses-permission android:name="android.permission.CHANGE_WIFI_STATE" />

连接：

    try {
    String ssid = null;
    if (wifi == Wifi.PCAN_WIRELESS_GATEWAY) {
        ssid = AesPrefs.get(AesConst.PCAN_WIRELESS_SSID,
                context.getString(R.string.pcan_wireless_ssid_default));
    } else if (wifi == Wifi.KJ_WIFI) {
        ssid = context.getString(R.string.remote_wifi_ssid_default);
    }

    WifiManager wifiManager = (WifiManager) context.getApplicationContext()
            .getSystemService(Context.WIFI_SERVICE);

    List<WifiConfiguration> wifiConfigurations = wifiManager.getConfiguredNetworks();

    for (WifiConfiguration wifiConfiguration : wifiConfigurations) {
        if (wifiConfiguration.SSID.equals("\"" + ssid + "\"")) {
            wifiManager.enableNetwork(wifiConfiguration.networkId, true);
            Log.i(TAG, "connectToWifi: will enable " + wifiConfiguration.SSID);
            wifiManager.reconnect();
            return null; // return! (sometimes logcat showed me network-entries twice,
            // which may will end in bugs)
        }
    }
} catch (NullPointerException | IllegalStateException e) {
    Log.e(TAG, "connectToWifi: Missing network configuration.");
}
return null;

我绞尽脑汁去理解为什么你的 WPA/WPA2 答案不起作用......经过几个小时的尝试，我发现了你缺少的东西：

conf.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);

WPA 网络需要！！！

现在，它可以工作了:)

您可以对这个活动进行子类化，以强制连接到特定的 wifi： https://github.com/zoltanersek/android-wifi-activity/blob/master/app/src/main/java/com/zoltanersek/androidwifiactivity/WifiActivity.java

您需要对此活动进行子类化并实现其方法：

public class SampleActivity extends WifiBaseActivity {
  @Override
  protected void onCreate(Bundle savedInstanceState) {
      super.onCreate(savedInstanceState);
  }

  @Override
  protected int getSecondsTimeout() {
      return 10;
  }

  @Override
  protected String getWifiSSID() {
      return "WifiNetwork";
  }

  @Override
  protected String getWifiPass() {
      return "123456";
  }
}

我也尝试连接到网络。 上面提出的解决方案均不适用于hugerock t70。 函数 wifiManager.disconnect();不会与当前网络断开连接。 因此无法重新连接到指定的网络。 我修改了上面的代码。 对我来说，下面的代码完美运行：

String networkSSID = "test";
String networkPass = "pass";

WifiConfiguration conf = new WifiConfiguration();
conf.SSID = "\"" + networkSSID + "\"";   
conf.wepKeys[0] = "\"" + networkPass + "\""; 
conf.wepTxKeyIndex = 0;
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40); 
conf.preSharedKey = "\""+ networkPass +"\"";

WifiManager wifiManager =         
(WifiManager)context.getSystemService(Context.WIFI_SERVICE);    

int networkId = wifiManager.addNetwork(conf);
wifi_inf = wifiManager.getConnectionInfo();

/////important!!!
wifiManager.disableNetwork(wifi_inf.getNetworkId());
/////////////////

wifiManager.enableNetwork(networkId, true);

试试这个方法。这很简单：

public static boolean setSsidAndPassword(Context context, String ssid, String ssidPassword) {
    try {
        WifiManager wifiManager = (WifiManager) context.getSystemService(context.WIFI_SERVICE);
        Method getConfigMethod = wifiManager.getClass().getMethod("getWifiApConfiguration");
        WifiConfiguration wifiConfig = (WifiConfiguration) getConfigMethod.invoke(wifiManager);

        wifiConfig.SSID = ssid;
        wifiConfig.preSharedKey = ssidPassword;

        Method setConfigMethod = wifiManager.getClass().getMethod("setWifiApConfiguration", WifiConfiguration.class);
        setConfigMethod.invoke(wifiManager, wifiConfig);

        return true;
    } catch (Exception e) {
        e.printStackTrace();
        return false;
    }
}

对于那些试图在 Xamarin 和/或毛伊岛实现这一目标的人来说只是一个更新：

  String networkSSID = "your network name as visible in your network tab";
  String networkPass = "your network key";

  WifiConfiguration conf = new WifiConfiguration();
  conf.Ssid = "\"" + networkSSID + "\"";
  conf.PreSharedKey = "\"" + networkPass + "\"";
  int netId = wifiMgr.AddNetwork(conf);
  wifiMgr.Disconnect();
  wifiMgr.EnableNetwork(netId, true);
  wifiMgr.Reconnect();

...确保您之前在设备上忘记了网络并请求许可（例如在应用程序启动时:)

    status = await Permissions.RequestAsync<Permissions.LocationWhenInUse>();
    status = await Permissions.RequestAsync<Permissions.NearbyWifiDevices>();
