You can use the following method:

ConnectivityManager conectivtyManager = (ConnectivityManager) ctx.getSystemService(Context.CONNECTIVITY_SERVICE);  
if (conectivtyManager.getActiveNetworkInfo() != null  
    && conectivtyManager.getActiveNetworkInfo().isAvailable()  
    && conectivtyManager.getActiveNetworkInfo().isConnected()) {  
    isConnected = true;  
} else {  
    isConnected= false;  
}  

Hope it helps!

For wifi:

ConnectivityManager mgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = mgr.getNetworkInfo(ConnectivityManager.TYPE_WIFI);
connected = networkInfo != null && networkInfo.isConnected();

For Mobile:

ConnectivityManager mgr = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo networkInfo = mgr.getNetworkInfo(ConnectivityManager.TYPE_MOBILE);
connected = networkInfo != null && networkInfo.isConnected();
