Java 无法连接到WPA2 android

我正在使用以下代码连接android中的WPA2（我可以连接WEP和WPA）。但我只得到“扫描”状态。我无法连接WPA2网络。你能告诉我我需要做些什么改变才能使这个代码与wpa2 WiFi相关吗

private boolean saveWepConfigAndEnableNetwork(String ssid, String pass) {
    isAlreadyPresend = false;
    WifiConfiguration wc = new WifiConfiguration();
    wc.SSID = "\"" + ssid + "\""; // IMP! This should be in Quotes!!
    wc = checkPreviousConfiguration(wc);
    wc.hiddenSSID = true;
    wc.status = WifiConfiguration.Status.DISABLED;
    wc.priority = 40;
    wc.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
    wc.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
    wc.allowedProtocols.set(WifiConfiguration.Protocol.WPA);
    wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    wc.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED);
    wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    wc.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
    wc.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104);
    wc.preSharedKey = "\"" + pass + "\"";

    wc.wepKeys[0] = "\"" + pass + "\""; // This is the WEP Password
    wc.wepTxKeyIndex = 0;

    boolean res1 = wifi.setWifiEnabled(true);
    int res = 0;
    if(isAlreadyPresend){
        res = wifi.addNetwork(wc);
    }else{
        res = wifi.updateNetwork(wc);
    }

    Log.d("WifiPreference", "add Network returned " + res);
    boolean es = wifi.saveConfiguration();
    Log.d("WifiPreference", "saveConfiguration returned " + es);
    boolean b = wifi.enableNetwork(res, true);
    Log.d("WifiPreference", "enableNetwork returned " + b);
    return b;
}

// Check if this SSID is already stored. If it is, return that
// configuration.
// If not, return the configuration being tested.
public WifiConfiguration checkPreviousConfiguration(WifiConfiguration wc) {
    List<WifiConfiguration> configs = wifi.getConfiguredNetworks();
    for (WifiConfiguration config : configs) {
        if (config.SSID.equals(wc.SSID)){
            isAlreadyPresend = true;
            return config;
        }
    }
    return wc;
}

private boolean saveWepConfigAndEnableNetwork（字符串ssid，字符串pass）{
isAlreadyPresend=假；
WifiConfiguration wc=新的WifiConfiguration（）；
wc.SSID=“\”“+SSID+”\”“；//IMP！应该用引号括起来！！
wc=检查先前的配置（wc）；
wc.hiddenSSID=true；
wc.status=WifiConfiguration.status.DISABLED；
wc.priority=40；
wc.allowedKeyManagement.set（WifiConfiguration.keymanagement.NONE）；
wc.allowedProtocols.set（WifiConfiguration.Protocol.RSN）；
wc.allowedProtocols.set（WifiConfiguration.Protocol.WPA）；
wc.allowedAuthAlgorithms.set（WifiConfiguration.AuthAlgorithm.OPEN）；
wc.allowedAuthAlgorithms.set（WifiConfiguration.AuthAlgorithm.SHARED）；
wc.allowedPairwisecipher.set（WifiConfiguration.Pairwiseciper.CCMP）；
wc.allowedPairwisecipher.set（WifiConfiguration.Pairwiseciper.TKIP）；
AlloweGroupCiphers.set（WifiConfiguration.GroupCipher.WEP40）；
AlloweGroupCiphers.set（WifiConfiguration.GroupCipher.WEP104）；
wc.preSharedKey=“\”+通过+“\”；
wc.wepKeys[0]=“\”“+pass+”\”“；//这是WEP密码
wc.wepTxKeyIndex=0；
布尔值res1=wifi.setWifiEnabled（真）；
int res=0；
如果（isAlreadyPresend）{
res=wifi.addNetwork（wc）；
}否则{
res=wifi.updateNetwork（wc）；
}
Log.d（“WifiPreference”，“添加返回的网络”+res）；
布尔es=wifi.saveConfiguration（）；
Log.d（“WifiPreference”、“saveConfiguration returned”+es）；
布尔b=wifi.enableNetwork（res，true）；
Log.d（“WifiPreference”、“enableNetwork returned”+b）；
返回b；
}
//检查此SSID是否已存储。如果是，请将其退回
//配置。
//如果没有，返回正在测试的配置。
公共无线配置检查先前配置（无线配置wc）{
List configs=wifi.getConfiguredNetworks（）；
用于（WifiConfiguration config:configs）{
if（config.SSID.equals（wc.SSID））{
isAlreadyPresend=真；
返回配置；
}
}
返回wc；
}

以下是我用来连接WPA2的代码

// Adding a WPA or WPA2 network
public static void changeNetworkWPA(WifiManager wifiManager, String ssid, String password) {
    WifiConfiguration config = changeNetworkCommon(ssid);
    // Hex passwords that are 64 bits long are not to be quoted.
    config.preSharedKey = quoteNonHex(password, 64);
    config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
    config.allowedProtocols.set(WifiConfiguration.Protocol.WPA); // For WPA
    config.allowedProtocols.set(WifiConfiguration.Protocol.RSN); // For WPA2
    config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
    config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_EAP);
    config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
    config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
    config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
    config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
    updateNetwork(wifiManager, config);
}
