1. 扫描WIFI热点

调用WifiManager.startScan()

  1. 	final int MSG_SCAN_START = 0x01;
  2. 	//final int MSG_SCAN_COMPLETE = 0x02;
  3. 	private Handler mHandler = new Handler() {
  4. 		public void handleMessage(Message msg) {
  5. 			if (MSG_SCAN_START == msg.what) {
  6. 				if(debugScan)ALog.d(TAG, "start scan wifi access point");
  7. 				mWifiManager.startScan();//启动扫描
  8. 	        	//we should start scan again to refresh wifi list state after every 10 sec
  9. 	        	mHandler.sendEmptyMessageDelayed(MSG_SCAN_START, 10 * 1000);
  10. 			}
  11. /*			if (MSG_SCAN_COMPLETE == msg.what) {
  12. 				onWifiScanSuccess();
  13. 			}*/
  14. 		};
  15. 	};

 监听WIFI状态变化

  1. IntentFilter filter = new IntentFilter();
  2. //WIFI 开关		 
  3. filter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
  4. //网络连接状态,	 
  5. filter.addAction(WifiManager.NETWORK_STATE_CHANGED_ACTION);
  6. //扫描结果		 
  7. filter.addAction(WifiManager.SCAN_RESULTS_AVAILABLE_ACTION);
  8. 		 wifiReceiver = new WifiChangedReceiver();
  9. 		 registerReceiver(wifiReceiver, filter);

 扫描完成后,通过获取ScanResult来显示列表, 

  1. //ScanResult 中, 包含了SSID, BSSID, 加密码类型等信息.
  2. mWifiManager.getScanResults();

 要完整的状态还需要配合 WifiConfiguration一起:

  1. //如验证失败原因
  2.                switch (mConfig.disableReason) {
  3.                     case WifiConfiguration.DISABLED_AUTH_FAILURE:
  4.                         summary.append(context.getString(R.string.wifi_disabled_password_failure));
  5.                         break;
  6.                     case WifiConfiguration.DISABLED_DHCP_FAILURE:
  7.                     case WifiConfiguration.DISABLED_DNS_FAILURE:
  8.                         summary.append(context.getString(R.string.wifi_disabled_network_failure));
  9.                         break;
  10.                     case WifiConfiguration.DISABLED_UNKNOWN_REASON:
  11.                     case WifiConfiguration.DISABLED_ASSOCIATION_REJECT:
  12.                         summary.append(context.getString(R.string.wifi_disabled_generic));
  13.                         break;

 

2.  WIFI开关

  1. //开关的代码比较简单:
  2. WifiManager.setWifiEnabled(boolean open)

 

状态监听:

  1. 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
  2. 	            int wifiState = intent.getIntExtra(WifiManager.EXTRA_WIFI_STATE, 0);
  3. 	            Log.i(TAG, "wifiState" + wifiState);
  4. 	            switch (wifiState) {
  5. 		            case WifiManager.WIFI_STATE_DISABLED:
  6. 		                break;
  7. 		            case WifiManager.WIFI_STATE_DISABLING:
  8. 		                break;
  9. 		            case WifiManager.WIFI_STATE_ENABLED:{
  10. 		            	Log.i(TAG, "WIFI_STATE_ENABLED");
  11. 		            	mHandler.sendEmptyMessageDelayed(MSG_SCAN_START, 1000);
  12. 		            	break;
  13. 		            }
  14. 	            //
  15. 	            }

 

3. WIFI热点连接

  1. 	/*** 
  2. 	* 配置要连接的WIFI热点信息     
  3. 	* @param SSID 
  4. 	* @param password 
  5. 	* @param type  加密类型

  7. 	*/       
  8. 	public WifiConfiguration createWifiInfo(String SSID, String password, int type) {    
  9. 	     
  10. 		Log.e(TAG, "SSID = " + SSID + "## Password = " + password + "## Type = " + type);

  21. 			WifiConfiguration tempConfig = wifiAdmin.IsExsits(SSID);    
  22. 			if (tempConfig != null) {    
  23. 			settingWifimin.AdwifiManager.removeNetwork(tempConfig.networkId);     
  24. 		} */   
  25. 	   
  26. 		// 分为三种情况：没有密码   用wep加密  用wpa加密

  42. 		
  43. 		} else if (type == SECURITY_WPA) {   // WIFICIPHER_WPA    
  44. 			config.preSharedKey = "\"" + password + "\"";

  67. 		config.linkProperties = new LinkProperties(m_linkProperties);*/
  68. 		return config;    
  69. 	}

 连接:

  1. int networkId = WifiManager.addNetwork(WifiConfiguration config);
  2. //若已存在, 无需调用, 当然, 也可调用remove
  3. WifiManager.removeNetwork(int networkId);
  4.  
  5. //最后
  6. WifiManager.enableNetwork(int NetworkId, boolean disableOther)

 

断开连接:

  1. //获取networkId
  2. public int getNetworkIdFromConfigByName(String name){
  3. 		int id = -1;
  4.                 List<WifiConfiguration> mWifiConfigList = WifiManager.getConfiguredNetworks();
  5.  
  6. 		for(WifiConfiguration conf : mWifiConfigList){
  7. 			if(conf.SSID.equals(name)){
  8. 				return conf.networkId;
  9. 			}
  10. 		}
  11. 		return id;
  12. 	}
  13.  
  14. //删除WIFI并断开:
  15. private boolean  RemoveWifi(int netId){
  16. 		return mWifiManager.removeNetwork(netId);
  17. 	}
