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任何网络。
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。
我怎么做呢?

这是一个你可以子类化的活动，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
你需要子类化这个活动并实现它的方法:
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";
}
}

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;
}
}

对我有效的解决方案是在这个线程中结合以上贡献者。
获取ScanResult的过程如下。
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();
}
};
注意在onPause和onStop上取消注册。
public void connectWiFi(ScanResult scanResult) {
try {
Log.v("rht", "Item clicked, SSID " + scanResult.SSID + " Security : " + scanResult.capabilities);
String networkSSID = scanResult.SSID;
String networkPass = "12345678";
WifiConfiguration conf = new WifiConfiguration();
conf.SSID = "\"" + networkSSID + "\""; // Please note the quotes. String should contain ssid in quotes
conf.status = WifiConfiguration.Status.ENABLED;
conf.priority = 40;
if (scanResult.capabilities.toUpperCase().contains("WEP")) {
Log.v("rht", "Configuring WEP");
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
conf.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
conf.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
conf.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
if (networkPass.matches("^[0-9a-fA-F]+$")) {
conf.wepKeys[0] = networkPass;
} else {
conf.wepKeys[0] = "\"".concat(networkPass).concat("\"");
}
conf.wepTxKeyIndex = 0;
} else if (scanResult.capabilities.toUpperCase().contains("WPA")) {
Log.v("rht", "Configuring WPA");
conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
conf.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
conf.preSharedKey = "\"" + networkPass + "\"";
} else {
Log.v("rht", "Configuring OPEN network");
conf.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
conf.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
conf.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
conf.allowedAuthAlgorithms.clear();
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
conf.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
conf.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
}
WifiManager wifiManager = (WifiManager) WiFiApplicationCore.getAppContext().getSystemService(Context.WIFI_SERVICE);
int networkId = wifiManager.addNetwork(conf);
Log.v("rht", "Add result " + networkId);
List<WifiConfiguration> list = wifiManager.getConfiguredNetworks();
for (WifiConfiguration i : list) {
if (i.SSID != null && i.SSID.equals("\"" + networkSSID + "\"")) {
Log.v("rht", "WifiConfiguration SSID " + i.SSID);
boolean isDisconnected = wifiManager.disconnect();
Log.v("rht", "isDisconnected : " + isDisconnected);
boolean isEnabled = wifiManager.enableNetwork(i.networkId, true);
Log.v("rht", "isEnabled : " + isEnabled);
boolean isReconnected = wifiManager.reconnect();
Log.v("rht", "isReconnected : " + isReconnected);
break;
}
}
} catch (Exception e) {
e.printStackTrace();
}
}

我也试着连接到网络。 以上提出的解决方案都不适用于hugerock t70。 wifiManager.disconnect()函数;不断开当前网络。 Аnd因此不能重新连接到指定的网络。 我修改了上面的代码。 对我来说，代码bolow工作完美:
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);
我绞尽脑汁才明白为什么你的WPA/WPA2答案不管用……经过几个小时的尝试，我找到了你所缺少的:
conf.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
需要WPA网络!!!!
现在，它工作了:)
