以编程方式安装Android WiFi

Question

你知道如何在我的Android应用程序中建立一个发送密码的wifi连接吗？

Answer 1

将SSID及其密码传递给以下方法.

public void connectToAP(String ssid, String passkey) {
    Log.i(TAG, "* connectToAP");

    WifiConfiguration wifiConfiguration = new WifiConfiguration();

    String networkSSID = ssid;
    String networkPass = passkey;

    Log.d(TAG, "# password " + networkPass);

    for (ScanResult result : scanResultList) {
        if (result.SSID.equals(networkSSID)) {

            String securityMode = getScanResultSecurity(result);

            if (securityMode.equalsIgnoreCase("OPEN")) {

                wifiConfiguration.SSID = "\"" + networkSSID + "\"";
                wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
                int res = wifiManager.addNetwork(wifiConfiguration);
                Log.d(TAG, "# add Network returned " + res);

                boolean b = wifiManager.enableNetwork(res, true);
                Log.d(TAG, "# enableNetwork returned " + b);

                wifiManager.setWifiEnabled(true);

            } else if (securityMode.equalsIgnoreCase("WEP")) {

                wifiConfiguration.SSID = "\"" + networkSSID + "\"";
                wifiConfiguration.wepKeys[0] = "\"" + networkPass + "\"";
                wifiConfiguration.wepTxKeyIndex = 0;
                wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE);
                wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40);
                int res = wifiManager.addNetwork(wifiConfiguration);
                Log.d(TAG, "### 1 ### add Network returned " + res);

                boolean b = wifiManager.enableNetwork(res, true);
                Log.d(TAG, "# enableNetwork returned " + b);

                wifiManager.setWifiEnabled(true);
            }

            wifiConfiguration.SSID = "\"" + networkSSID + "\"";
            wifiConfiguration.preSharedKey = "\"" + networkPass + "\"";
            wifiConfiguration.hiddenSSID = true;
            wifiConfiguration.status = WifiConfiguration.Status.ENABLED;
            wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
            wifiConfiguration.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
            wifiConfiguration.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
            wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
            wifiConfiguration.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP);
            wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.RSN);
            wifiConfiguration.allowedProtocols.set(WifiConfiguration.Protocol.WPA);

            int res = wifiManager.addNetwork(wifiConfiguration);
            Log.d(TAG, "### 2 ### add Network returned " + res);

            wifiManager.enableNetwork(res, true);

            boolean changeHappen = wifiManager.saveConfiguration();

            if(res != -1 && changeHappen){
                Log.d(TAG, "### Change happen");

                AppStaticVar.connectedSsidName = networkSSID;

            }else{
                Log.d(TAG, "*** Change NOT happen");
            }

            wifiManager.setWifiEnabled(true);
        }
    }
}

public String getScanResultSecurity(ScanResult scanResult) {
    Log.i(TAG, "* getScanResultSecurity");

    final String cap = scanResult.capabilities;
    final String[] securityModes = { "WEP", "PSK", "EAP" };

    for (int i = securityModes.length - 1; i >= 0; i--) {
        if (cap.contains(securityModes[i])) {
            return securityModes[i];
        }
    }

    return "OPEN";
}

不要忘记在Manifest文件中添加必要的权限.

100%有效.

通过这种方式,您可以连接到您的特定Wif此代码用于MainActivity.java

////////////// >>> Wifi Connection(WP2)<<< ////////////////

        WifiConfiguration wifiConfig = new WifiConfiguration();

        wifiConfig.SSID = String.format("\"%s\"", "Wifi name");
        wifiConfig.preSharedKey = String.format("\"%s\"", "Wifi password");

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

另外,不要忘记将此代码包含在AndroidManifest.xml中

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