1.检测网络是否可用
public boolean isNetWorkConnected() {
ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
return ni != null && ni.isConnectedOrConnecting();
}
需要权限：
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
2.获取网络连接方式
public static final int NETTYPE_WIFI = 0x01;
public static final int NETTYPE_CMWAP = 0x02;
public static final int NETTYPE_CMNET = 0x03;
/**
* 获取当前网络类型
*
* @return 0：没有网络 1：WIFI网络 2：WAP网络 3：NET网络
*/
public int getNetworkType() {
int netType = 0;
ConnectivityManager cm = (ConnectivityManager)getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo ni = cm.getActiveNetworkInfo();
if(ni != null) {
int nType = ni.getType();
if(nType == ConnectivityManager.TYPE_MOBILE) {
String extraInfo = ni.getExtraInfo();
if(!isEmpty(extraInfo)) {
if (extraInfo.toLowerCase().equals("cmnet")) {
netType = NETTYPE_CMNET;
} else {
netType = NETTYPE_CMWAP;
}
}
} else if (nType == ConnectivityManager.TYPE_WIFI) {
netType = NETTYPE_WIFI;
}
}
return netType;
}
