实际应用开发时,如果存在需要用户获取大量数据的情况,最好是先判断下网络类型,提示用户当前的网络类型,是否需要连接Wifi,etc.
(手机流量太贵啦,当然土豪是无视这玩意的, (/ □ \)).
定义网络连接类型:
public static final int NETTYPE_NULL = 0x00; //未连接网络 public static final int NETTYPE_WIFI = 0x01; //WIFI public static final int NETTYPE_MOBILE = 0x02;//MOBILE
判断网络连接类型:
/* * 获取当前网络类型 * @param context * @return */ public int getNetType(Context context) { int netType = NETTYPE_NULL; ConnectivityManager connectivityManager = (ConnectivityManager)context .getSystemService(Context.CONNECTIVITY_SERVICE); NetworkInfo activeNetworkInfo = connectivityManager.getActiveNetworkInfo(); if (activeNetworkInfo == null) { return netType; } int nType = activeNetworkInfo.getType(); if (nType == ConnectivityManager.TYPE_WIFI) { netType = NETTYPE_WIFI; }else if (netType == ConnectivityManager.TYPE_MOBILE) { netType = NETTYPE_MOBILE; } return netType; }
当然,想访问网络状态,AndroidMainfest.xml中要加入权限:
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
