Android WiFi功能开发

Android WiFi功能开发

1、功能说明

         在桌面弹窗用 滑动按钮 进行wifi的开关、wifi切换、wifi密码记录。

2、功能

在桌面启动弹窗

WindowManager wm = this.getWindowManager();
		int width = wm.getDefaultDisplay().getWidth();
		int hight = wm.getDefaultDisplay().getHeight();
		LayoutInflater inflater = (LayoutInflater) this
				.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		View mainview = inflater.inflate(R.layout.dialog_target, null);
		setContentView(mainview, new LayoutParams(width * 10 / 13,
				hight * 3 / 5));

打开/关闭WiFi

/**
	 * 打开Wifi网卡
	 */
	public void openNetCard() {
		if (!mWifiManager.isWifiEnabled()) {
			mWifiManager.setWifiEnabled(true);

		}
	}

	/**
	 * 关闭Wifi网卡
	 */
	public void closeNetCard() {
		if (mWifiManager.isWifiEnabled()) {
			mWifiManager.setWifiEnabled(false);

		}
	}

扫描周边网络

/**
	 * 扫描周边网络
	 */
	public void scan() {
		mWifiManager.startScan();
		listResult = mWifiManager.getScanResults();
		if (listResult != null) {
			Log.i(TAG, "当前区域存在无线网络，请查看扫描结果");
		} else {
			Log.i(TAG, "当前区域没有无线网络");
		}
	}

连接/断开wifi

/**
	 * 连接指定网络
	 */
	public void connect() {
		mWifiInfo = mWifiManager.getConnectionInfo();

	}

	/**
	 * 断开当前连接的网络
	 */
	public void disconnectWifi() {
		int netId = getNetworkId();
		mWifiManager.disableNetwork(netId);
		mWifiManager.disconnect();
		mWifiInfo = null;
	}

根据不同加密方式，用密码和名称连接指定wifi

/**
	 * 连接到指定的wifi
	 */
	public int connectwifi(String name,String password,String capabilities){
		WifiConfiguration config = new WifiConfiguration();
		config.allowedAuthAlgorithms.clear();  
        config.allowedGroupCiphers.clear();  
        config.allowedKeyManagement.clear();  
        config.allowedPairwiseCiphers.clear();  
        config.allowedProtocols.clear();  
//		config.SSID = "\"HI-LINK_4E77\"";
		config.SSID = "\"" +name+ "\"";
//	    config.preSharedKey = "\"12345678\"";
		if(capabilities.equals("[ESS]")){
//			config.wepKeys[0] = "";  
			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(capabilities.contains("WEP")){
			config.hiddenSSID = true;  
            config.wepKeys[0] = "\"" + password + "\"";  
			 config.allowedAuthAlgorithms.set(WifiConfiguration.AuthAlgorithm.OPEN);
            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 {
		config.preSharedKey = "\""+password +"\"";
        config.hiddenSSID = true;
        config.status = WifiConfiguration.Status.ENABLED;
        config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.TKIP);
        config.allowedGroupCiphers.set(WifiConfiguration.GroupCipher.CCMP);
        config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.TKIP);
        config.allowedPairwiseCiphers.set(WifiConfiguration.PairwiseCipher.CCMP); 
        config.allowedKeyManagement.set(WifiConfiguration.KeyMgmt.WPA_PSK);
        config.allowedProtocols.set(WifiConfiguration.Protocol.WPA);  
		}
        int netId = mWifiManager.addNetwork(config);
        mWifiManager.enableNetwork(netId, true);
        return netId;
	}
