1. 扫描WIFI热点
调用WifiManager.startScan()
final int MSG_SCAN_START = 0x01; //final int MSG_SCAN_COMPLETE = 0x02; private Handler mHandler = new Handler() { public void handleMessage(Message msg) { if (MSG_SCAN_START == msg.what) { if(debugScan)ALog.d(TAG, "start scan wifi access point"); mWifiManager.startScan();//启动扫描 //we should start scan again to refresh wifi list state after every 10 sec mHandler.sendEmptyMessageDelayed(MSG_SCAN_START, 10 * 1000); } /* if (MSG_SCAN_COMPLETE == msg.what) { onWifiScanSuccess(); }*/ }; };
监听WIFI状态变化
IntentFilter filter = new IntentFilter(); //WIFI 开关 filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION); //网络连接状态, filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION); //扫描结果 filter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION); wifiReceiver = new WifiChangedReceiver(); registerReceiver(wifiReceiver, filter);
扫描完成后,通过获取ScanResult来显示列表,
//ScanResult 中, 包含了SSID, BSSID, 加密码类型等信息. mWifiManager.getScanResults();
要完整的状态还需要配合 WifiConfiguration一起:
//如验证失败原因 switch (mConfig.disableReason) { case WifiConfiguration.DISABLED_AUTH_FAILURE: summary.append(context.getString(R.string.wifi_disabled_password_failure)); break; case WifiConfiguration.DISABLED_DHCP_FAILURE: case WifiConfiguration.DISABLED_DNS_FAILURE: summary.append(context.getString(R.string.wifi_disabled_network_failure)); break; case WifiConfiguration.DISABLED_UNKNOWN_REASON: case WifiConfiguration.DISABLED_ASSOCIATION_REJECT: summary.append(context.getString(R.string.wifi_disabled_generic)); break;
2. WIFI开关
//开关的代码比较简单: WifiManager.setWifiEnabled(boolean open)
状态监听:
if (WifiManager.WIFI_STATE_CHANGED_ACTION.equals(intent.getAction())) {// 这个监听wifi的打开与关闭，与wifi的连接无关 int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, 0); Log.i(TAG, "wifiState" + wifiState); switch (wifiState) { case WifiManager.WIFI_STATE_DISABLED: break; case WifiManager.WIFI_STATE_DISABLING: break; case WifiManager.WIFI_STATE_ENABLED:{ Log.i(TAG, "WIFI_STATE_ENABLED"); mHandler.sendEmptyMessageDelayed(MSG_SCAN_START, 1000); break; } // }
3. WIFI热点连接
/*** * 配置要连接的WIFI热点信息 * @param SSID * @param password * @param type 加密类型 * @return */ public WifiConfiguration createWifiInfo(String SSID, String password, int type) { Log.e(TAG, "SSID = " + SSID + "## Password = " + password + "## Type = " + type); WifiConfiguration config = new WifiConfiguration(); config.allowedAuthAlgorithms.clear(); config.allowedGroupCiphers.clear(); config.allowedKeyManagement.clear(); config.allowedPairwiseCiphers.clear(); config.allowedProtocols.clear(); config.SSID = "\"" + SSID + "\""; /*//增加热点时候 如果已经存在SSID 则将SSID先删除以防止重复SSID出现 WifiConfiguration tempConfig = wifiAdmin.IsExsits(SSID); if (tempConfig != null) { settingWifimin.AdwifiManager.removeNetwork(tempConfig.networkId); } */ // 分为三种情况：没有密码 用wep加密 用wpa加密 if (type == SECURITY_NONE) { // WIFICIPHER_NOPASS config.wepKeys[0] = ""; config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); config.wepTxKeyIndex = 0; } else if (type == SECURITY_WEP) { // WIFICIPHER_WEP config.hiddenSSID = true; config.wepKeys[0] = "\"" + password + "\""; config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.SHARED); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP40); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.WEP104); config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.NONE); config.wepTxKeyIndex = 0; } else if (type == SECURITY_WPA) { // 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); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP); config.status = WifiConfiguration.Status.ENABLED; */ 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); config.allowedProtocols.set(WifiConfiguration.Protocol.WPA); config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP); config.allowedPairwiseCiphers .set(WifiConfiguration.PairwiseCipher.CCMP); config.status = WifiConfiguration.Status.ENABLED; } /*config.proxySettings = ProxySettings.NONE; config.ipAssignment = m_ipAssignment; config.linkProperties = new LinkProperties(m_linkProperties);*/ return config; }
连接:
int networkId = WifiManager.addNetwork(WifiConfiguration config); //若已存在, 无需调用, 当然, 也可调用remove WifiManager.removeNetwork(int networkId); //最后 WifiManager.enableNetwork(int NetworkId, boolean disableOther)
断开连接:
//获取networkId public int getNetworkIdFromConfigByName(String name){ int id = -1; List<WifiConfiguration> mWifiConfigList = WifiManager.getConfiguredNetworks(); for(WifiConfiguration conf : mWifiConfigList){ if(conf.SSID.equals(name)){ return conf.networkId; } } return id; } //删除WIFI并断开: private boolean RemoveWifi(int netId){ return mWifiManager.removeNetwork(netId); }
