首先在AndroidManifest.xml添加權(quán)限

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

1,判斷是否有網(wǎng)絡(luò)連接

public boolean isNetworkConnected(Context context) { if (context != null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo(); if (mNetworkInfo != null) { return mNetworkInfo.isAvailable(); } } return false; }
2.判斷WIFI網(wǎng)絡(luò)是否可用

public boolean isWifiConnected(Context context) { if (context != null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo mWiFiNetworkInfo = mConnectivityManager .getNetworkInfo(ConnectivityManager.TYPE_WIFI); if (mWiFiNetworkInfo != null) { return mWiFiNetworkInfo.isAvailable(); } } return false; }
3.判斷MOBILE網(wǎng)絡(luò)是否可用

public boolean isMobileConnected(Context context) { if (context != null) { ConnectivityManager mConnectivityManager = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo mMobileNetworkInfo = mConnectivityManager .getNetworkInfo(ConnectivityManager.TYPE_MOBILE); if (mMobileNetworkInfo != null) { return mMobileNetworkInfo.isAvailable(); } } return false; }
4.判斷網(wǎng)絡(luò)類型

//返回值 -1：沒有網(wǎng)絡(luò) 1：WIFI網(wǎng)絡(luò)2：wap網(wǎng)絡(luò)3：net網(wǎng)絡(luò)public static int GetNetype(Context context){ int netType = -1; ConnectivityManager connMgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkInfo = connMgr.getActiveNetworkInfo(); if(networkInfo==null){ return netType; } int nType = networkInfo.getType(); if(nType==ConnectivityManager.TYPE_MOBILE){ if(networkInfo.getExtraInfo().toLowerCase().equals("cmnet")){ netType = 3; } else{ netType = 2; } } else if(nType==ConnectivityManager.TYPE_WIFI){ netType = 1; } return netType; }
