项目开发中经常会用到Wifi连接

Wifi连接分两种情况有密码和无密码

一下两种方法分别是连接有密码和无密码的方法

经过小米2S和三星平板验证

//连接有密码的Wifi

private void connectToWifi(String SSID, String key) {

WifiManager wifi = (WifiManager) getSystemService(Context.WIFI_SERVICE);

WifiConfiguration wc = new WifiConfiguration();

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);

}

//连接无密码的Wifi

// 连接Wifi

private void connectToWifi(String SSID) {

WifiConfiguration config = new WifiConfiguration();

config.allowedAuthAlgorithms.clear();

config.allowedGroupCiphers.clear();

config.allowedKeyManagement.clear();

config.allowedPairwiseCiphers.clear();

config.allowedProtocols.clear();

config.SSID = "\"" + SSID + "\"";

//这个好像不太稳定，之前可以连接有密码的，现在又不行了，不清楚是什么原因

// config.wepKeys[0] = password; // 这里要注释掉 因为连接的是没有密码的Wifi

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

config.wepTxKeyIndex = 0;

WifiManager wifiManager = (WifiManager) context

.getSystemService(Context.WIFI_SERVICE);

wifiManager.enableNetwork(wifiManager.addNetwork(config), true);

}
