(1)判断网络是否可用
public static boolean isConn(Context context) {
boolean bisConnFlag = false;
ConnectivityManager conManager = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo network = conManager.getActiveNetworkInfo();
if (network != null) {
bisConnFlag = conManager.getActiveNetworkInfo().isAvailable();
}
return bisConnFlag;
}
(2)判断wifi是否可用
public static boolean isWifiActive(Context icontext) {
Context context = icontext.getApplicationContext();
ConnectivityManager connectivity = (ConnectivityManager) context
.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo[] info;
if (connectivity != null) {
info = connectivity.getAllNetworkInfo();
if (info != null) {
for (int i = 0; i < info.length; i++) {
if (info[i].getTypeName().equals("WIFI")
&& info[i].isConnected()) {
return true;
}
}
}
}
return false;
}
