今天在一位很牛逼的学长的博客里面看到了这段代码后，很是激动啊，于是就“偷”了过来，嘿嘿。。。。为自己也为更多需要它的程序媛
直接上代码：
public class GetNetWorkStateActor extends FusionActor {
@Override
public boolean processFusionMessage(FusionMessage msg) {
// TODO Auto-generated method stub
msg.setResponseData(checkNet());
return false;
}
private int checkNet() {
// TODO Auto-generated method stub
ConnectivityManager connectivityManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo mobNetInfoActivity = connectivityManager
.getActiveNetworkInfo();
int netFlag = 0;
if (mobNetInfoActivity != null) {
switch (mobNetInfoActivity.getType()) {
case ConnectivityManager.TYPE_ETHERNET:
// ethernet
netFlag = 1;
break;
case ConnectivityManager.TYPE_WIFI:
// wifi
netFlag = 2;
break;
case ConnectivityManager.TYPE_MOBILE:
// gprs
if(isFastMobileNetwork(context)){
//2g
netFlag = 3;
}else{
//3g
netFlag = 4;
}
break;
default:
break;
}
} else {
//no network
netFlag = 0;
}
return netFlag;
}
private static boolean isFastMobileNetwork(Context context) {
TelephonyManager telephonyManager = (TelephonyManager) context
.getSystemService(Context.TELEPHONY_SERVICE);
switch (telephonyManager.getNetworkType()) {
case TelephonyManager.NETWORK_TYPE_1xRTT:
return false; // ~ 50-100 kbps

}
}
}
