Android 判断手机网络状态

1，获取网络管理者ConnectivityManager mConMan = (ConnectivityManager )context.getSystemService(Context.CONNECTIVITY_SERVICE);像很多Android的服务管理者一样都是通过getSystemService();获得

2.同理得到wifi管理者 WifiManager

3。我们先判断是否连接wifi ： WifiInfo wifiInfo = WifiManager.getConnectionInfo(); int wifi = WifiManager.getWiFiState();

4.如果wifi没连接测继续判断是否是手机网络 NetworkInfo info = mConMan .getNetworkInfo(ConnectivityManager.TYPE_MOBILE);

代码如下：

ConnectivityManager mConnMgr = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
WifiManager wifiManager = (WifiManager) context
.getSystemService(Context.WIFI_SERVICE);
int wifiState = wifiManager.getWifiState();
WifiInfo wifiInfo = wifiManager.getConnectionInfo();
if (wifiInfo.getNetworkId() != -1
&& (wifiState == WifiManager.WIFI_STATE_ENABLED)) {
return WIFI_CONNECT;
} else {
NetworkInfo netInfo = mConnMgr
.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (netInfo == null || !netInfo.isConnected()
|| !netInfo.isAvailable()) {
return NO_NET_CONNECT;
} else {
String name = netInfo.getExtraInfo();
if (netInfo.getType() == ConnectivityManager.TYPE_MOBILE
&& name.toLowerCase().equals("cmwap")) {
return WAP_CONNECTED;
} else {
return NET_CONNECTED;
}
}
}
