Android检查手机网络状态及网络类型的方法

本文实例讲述了Android检查手机网络状态及网络类型的方法。分享给大家供大家参考。具体分析如下：

//judge network status is connecting or not
public static boolean checkNetworkConnected(Context context) {
if (null!=context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
if (null!=networkInfo) {
 return networkInfo.isAvailable();
 }
}
 return false;
}
//judge Wifi status is connecting or not
public static boolean checkWifiStatus(Context context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
if (null!=networkInfo
&& networkInfo.getType() == ConnectivityManager.TYPE_WIFI) {
return true;
 }
return false;
}
//judge 3G status is connecting or not
public static boolean check3GStatus(Context context) {
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = connectivityManager.getActiveNetworkInfo();
if (null!=networkInfo
&& networkInfo.getType() == ConnectivityManager.TYPE_MOBILE) {
return true;
 }
return false;
}

希望本文所述对大家的Android程序设计有所帮助。
