如何连接到特定的WIFI网络在Android中编程？

问题描述

我想设计的应用程序，显示无线网络列表提供连接到网络时选择它。我已经实现了部分显示的扫描结果。现在我想连接到由从扫描结果列表中的用户选择一个特定的网络。谁能告诉我该怎么做呢？

I want to design an app which shows a list of wifi networks available and connect to the network when it is selected. I have implemented the part showing the scan results. Now i want to connect to a particular network selected by the user from the list of scan results.Can anyone please tell me how to do this?

推荐答案

您需要创建这样的WifiConfiguration例如：

You need to create WifiConfiguration instance like this:

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，WEP的网络，你需要做的：

Then, for WEP network you need to do this:

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

有关WPA网络，你需要添加密码是这样的：

For WPA network you need to add passphrase like this:

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

有关开放式的网络，你需要做的：

For Open network you need to do this:

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

然后，你需要将它添加到Android的WiFi管理器设置：

Then, you need to add it to Android wifi manager settings:

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

最后，您可能需要启用它，因此Android连接到它：

And finally, you might need to enable it, so Android connects to it:

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：如果WEP，如果你的密码是十六进制，你不需要用引号括起来。

UPD: In case of WEP, if your password is in hex, you do not need to surround it with quotes.
