android連接指定的wifi

❶ Android如何添加隱藏的無線wifi配置文件

1、打開 設定 頁面，點擊 Wi-Fi

2、點擊 添加WLAN網路

3、手動輸入路由器的SSID、無線密碼等參數，點擊 儲存，保存無線配置文件

4、無線配置文件添加完成，無線信號顯示已連接

注意：添加了無線配置文件，手機重啟後（或手機從外面拿回家）會自動連接路由器的無線信號，不需要重新添加無線配置文件。

❷ android怎麼自動連接以zd開頭的wifi，知道密碼，想用代碼直接連接

public class WifiAutoConnectManager {
private static final String TAG = WifiAutoConnectManager.class.getSimpleName();
WifiManager wifiManager;
// 定義幾種加密方式，一種是WEP，一種是WPA，還有沒有密碼的情況 public enum WifiCipherType { WIFICIPHER_WEP, WIFICIPHER_WPA, WIFICIPHER_NOPASS, WIFICIPHER_INVALID }
// 構造函數 public WifiAutoConnectManager(WifiManager wifiManager) { this.wifiManager = wifiManager; }
// 提供一個外部介面，傳入要連接的無線網 public void connect(String ssid, String password, WifiCipherType type) { Thread thread = new Thread(new ConnectRunnable(ssid, password, type)); thread.start(); }
// 查看以前是否也配置過這個網路 private WifiConfiguration isExsits(String SSID) { List<WifiConfiguration> existingConfigs = wifiManager.getConfiguredNetworks(); for (WifiConfiguration existingConfig : existingConfigs) { if (existingConfig.SSID.equals("\"" + SSID + "\"")) { return existingConfig; } } return null; }
private WifiConfiguration createWifiInfo(String SSID, String Password, WifiCipherType Type) { WifiConfiguration config = new WifiConfiguration(); config.allowedAuthAlgorithms.clear(); config.allowedGroupCiphers.clear(); config.allowedKeyManagement.clear(); config.allowedPairwiseCiphers.clear(); config.allowedProtocols.clear(); config.SSID = "\"" + SSID + "\""; // nopass if (Type == WifiCipherType.WIFICIPHER_NOPASS) { config.wepKeys[0] = ""; config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); config.wepTxKeyIndex = 0; } // wep if (Type == WifiCipherType.WIFICIPHER_WEP) { if (!TextUtils.isEmpty(Password)) { if (isHexWepKey(Password)) { config.wepKeys[0] = Password; } else { config.wepKeys[0] = "\"" + Password + "\""; } } config.allowedAuthAlgorithms.set(AuthAlgorithm.OPEN); config.allowedAuthAlgorithms.set(AuthAlgorithm.SHARED); config.allowedKeyManagement.set(KeyMgmt.NONE); config.wepTxKeyIndex = 0; } // wpa if (Type == WifiCipherType.WIFICIPHER_WPA) { config.preSharedKey = "\"" + Password + "\""; config.hiddenSSID = true; config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK); config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP); // 此處需要修改否則不能自動重聯 // config.allowedProtocols.set(WifiConfiguration.Protocol.WPA); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP); config.status = WifiConfiguration.Status.ENABLED; } return config; }
// 打開wifi功能 private boolean openWifi() { boolean bRet = true; if (!wifiManager.isWifiEnabled()) { bRet = wifiManager.setWifiEnabled(true); } return bRet; }
class ConnectRunnable implements Runnable { private String ssid;
private String password;
private WifiCipherType type;
public ConnectRunnable(String ssid, String password, WifiCipherType type) { this.ssid = ssid; this.password = password; this.type = type; }
@Override public void run() { // 打開wifi openWifi(); // 開啟wifi功能需要一段時間(我在手機上測試一般需要1-3秒左右)，所以要等到wifi // 狀態變成WIFI_STATE_ENABLED的時候才能執行下面的語句 while (wifiManager.getWifiState() == WifiManager.WIFI_STATE_ENABLING) { try { // 為了避免程序一直while循環，讓它睡個100毫秒檢測…… Thread.sleep(100); } catch (InterruptedException ie) { } }
WifiConfiguration wifiConfig = createWifiInfo(ssid, password, type); // if (wifiConfig == null) { Log.d(TAG, "wifiConfig is null!"); return; }
WifiConfiguration tempConfig = isExsits(ssid);
if (tempConfig != null) { wifiManager.removeNetwork(tempConfig.networkId); }
int netID = wifiManager.addNetwork(wifiConfig); boolean enabled = wifiManager.enableNetwork(netID, true); Log.d(TAG, "enableNetwork status enable=" + enabled); boolean connected = wifiManager.reconnect(); Log.d(TAG, "enableNetwork connected=" + connected); } }
private static boolean isHexWepKey(String wepKey) { final int len = wepKey.length();
// WEP-40, WEP-104, and some vendors using 256-bit WEP (WEP-232?) if (len != 10 && len != 26 && len != 58) { return false; }
return isHex(wepKey); }
private static boolean isHex(String key) { for (int i = key.length() - 1; i >= 0; i--) { final char c = key.charAt(i); if (!(c >= '0' && c <= '9' || c >= 'A' && c <= 'F' || c >= 'a' && c <= 'f')) { return false; } }
return true; }}

❸ Android手機如何設置wifi設備名

1、首先打開手機設置，點擊選擇「其他無線連接」按鈕。

❹ android wifi 開發中 如何判斷成功連接上了指定的wifi熱點

首先通過WifiManager對象獲取系統服務的WIFI_SERVICE，然後調用getConnectionInfo（）獲得WifiInfo對象，再通過WifiInfo對象獲取已連上wifi的SSID(實際上是housyunhin說的WifiInfo.getSSID（）和其他wifi信息)，之後判斷是否匹配即可

❺ android 命令怎麼連接wifi點
