智能電視的網絡狀態和ip獲取(有線和無線)

1、網絡類型

//獲取網絡類型
ConnectivityManager connectivity = (ConnectivityManager) mContext.getSystemService(Context.CONNECTIVITY_SERVICE);
	if (connectivity == null) {
	    Log.w(Constants.TAG, "couldn't get connectivity manager");
	    return null;
	}

	NetworkInfo activeInfo = connectivity.getActiveNetworkInfo();
	if (activeInfo == null) {
	    if (Constants.LOGVV) {
		Log.v(Constants.TAG, "network is not available");
	    }
	    return null;
	}
	return activeInfo.getType();
	
	
	//判斷類型networkType = activeInfo.getType()
	  private int translateNetworkTypeToApiFlag(int networkType) {
        switch (networkType) {
            case ConnectivityManager.TYPE_MOBILE:
            	  DebugUtil.debugInfo("DownloadThread translateNetworkTypeToApiFlag: network type = TYPE_MOBILE");
                return DownloadManager.Request.NETWORK_MOBILE;

            case ConnectivityManager.TYPE_WIFI:
            	DebugUtil.debugInfo("DownloadThread translateNetworkTypeToApiFlag: network type = TYPE_WIFI");
                return DownloadManager.Request.NETWORK_WIFI;
            case 9: //新增，安卓智能電視網絡類型
            	DebugUtil.debugInfo("DownloadThread translateNetworkTypeToApiFlag: network type = 9");
                return 9;
            default:
            	DebugUtil.debugInfo("DownloadThread translateNetworkTypeToApiFlag: network type = UnKnow");
                return 0;
        }
    }

2、ip獲取

//獲取wifi ip
	// <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"/>
	public String getlocalip(Context m_Context){  
		String ip = "";
		try {
				DebugUtils.printInfo(TAG, "getlocalip");
				WifiManager wifiManager = (WifiManager)m_Context.getSystemService(Context.WIFI_SERVICE);    
		        WifiInfo wifiInfo = wifiManager.getConnectionInfo();    
		        int ipAddress = wifiInfo.getIpAddress();    
		        if(0 == ipAddress){
		        	ip =  "獲取失敗";  
		        }
		       ip = ((ipAddress & 0xff) + "." + (ipAddress>>8 & 0xff) + "." +(ipAddress>>16 & 0xff)+"."+(ipAddress>>24 & 0xff));  
		       DebugUtils.printInfo(TAG, "ip=" + ip);
		} catch (Exception e) {
			DebugUtils.printInfo(TAG, "getlocalip 異常:" + e.toString());
			e.printStackTrace();
		}
		return ip;
    }
	
	//獲取有線和無線ip
	private String getIP(){
		String ip = "";
		try {
			for (Enumeration<NetworkInterface> en = NetworkInterface.getNetworkInterfaces(); en.hasMoreElements(); ){
				NetworkInterface intf = en.nextElement(); 
				if (intf.getName().toLowerCase().equals("eth0") || intf.getName().toLowerCase().equals("wlan0")){
					for (Enumeration<InetAddress> enumIpAddr = intf.getInetAddresses(); enumIpAddr.hasMoreElements();) { 
						InetAddress inetAddress = enumIpAddr.nextElement();   
						if (!inetAddress.isLoopbackAddress()) {    
								String ipaddress = inetAddress.getHostAddress().toString();   
								if(!ipaddress.contains("::")){//ipV6的地址    
									Log.e(TAG, "get ip=" + ipaddress);
									ip = ipaddress;
									
									Toast.makeText(getApplicationContext(), "" + ip, Toast.LENGTH_SHORT).show();
									return ip;     
								}    
							}    
						}   
					} else {  
						continue;   
					} 
			} 
		} catch (Exception e) {
			e.printStackTrace();
		}
		Log.e(TAG, "get ip 失敗");
		return ip;
		
	}
	
	//獲取設備名
	 public String getDeviceName(){
	        return new Build().MODEL;
	 }

分析:
(1)intf.getName().toLowerCase().equals("eth0") || intf.getName().toLowerCase().equals("wlan0")

這裏表示:僅過濾無線和有線的ip. networkInterface是有很多的名稱的 比如sim0,remt1.....等等.我不需要用到就直接過濾了

(2)if(!ipaddress.contains("::")){//ipV6的地址

這裏表示: 過濾掉ipv6的地址.不管無線還是有線 都有這個地址, 我這邊顯示地址大體是:fe80::288:88ff:fe00:1%eth0 fe80::ee17:2fff:fece:c0b4%wlan0 一般都是出現在第一次循環.第二次循環就是真正的ipv4的地址.
