android 判断网络连接是否可用

1、判断连接的工具类类名：Network_status

2、/** * 判断网络连接是否可用 * @param context * @return */pu水瑞侮瑜bli艘早祓胂c static boolean is_Network_Available(Context context) { ConnectivityManager cm = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); if (cm == null) { } else { //如果仅仅是用来判断网络连接 //则可以使用 cm.getActiveNetworkInfo().isAvailable(); NetworkInfo[] info = cm.getAllNetworkInfo(); if (info != null) { for (int i = 0; i < info.length; i++) { if (info[i].getState() == NetworkInfo.State.CONNECTED) { return true; } } } } return false; }

3、/** * 判断GPS是否打开 * @param context * @return */public static boolean is_Gps_Enabled(Context context) { LocationManager lm = ((LocationManager) context .getSystemService(Context.LOCATION_SERVICE)); List<String> accessibleProviders = lm.getProviders(true); return accessibleProviders != null && accessibleProviders.size() > 0; }

4、/** * 判断WIFI是否打开 * @param context * @return */pu水瑞侮瑜bli艘早祓胂c static boolean is_Wifi_Enabled(Context context) { ConnectivityManager mgrConn = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); TelephonyManager mgrTel = (TelephonyManager) context .getSystemService(Context.TELEPHONY_SERVICE); return ((mgrConn.getActiveNetworkInfo() != null && mgrConn .getActiveNetworkInfo().getState() == NetworkInfo.State.CONNECTED) || mgrTel .getNetworkType() == TelephonyManager.NETWORK_TYPE_UMTS); }

5、/** * 判断是否是3G网络 * @param context * @return */public static boolean is_3rd(Context context) { ConnectivityManager cm = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkINfo = cm.getActiveNetworkInfo(); if (networkINfo != null && networkINfo.getType() == ConnectivityManager.TYPE_MOBILE) { return true; } return false; }

6、/** * 判断是wifi还是3g网络 * @param context * @return true(wifi) */public static boolean is_Wifi(Context context) { ConnectivityManager cm = (ConnectivityManager) context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo networkINfo = cm.getActiveNetworkInfo(); if (networkINfo != null && networkINfo.getType() == ConnectivityManager.TYPE_WIFI) { return true; } return false; }
