推荐答案
Check below code:
public boolean checkNetworkStatus() {
final ConnectivityManager connMgr = (ConnectivityManager) this
.getSystemService(Context.CONNECTIVITY_SERVICE);
final android.net.NetworkInfo wifi = connMgr
.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
final android.net.NetworkInfo mobile = connMgr
.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
if (wifi.isAvailable()) {
Toast.makeText(this, "Wifi connection.", Toast.LENGTH_LONG).show();
return true;
} else if (mobile.isAvailable()) {
Toast.makeText(this, "GPRS connection.", Toast.LENGTH_LONG).show();
return true;
} else {
